How Myer Set The All Time Points Record At UCC 2026
About this episode
After returning from UCC 2026, the Power Driven Podcast team breaks down how Meyer set the all-time points record. They explain the event’s structure—drag racing, dyno, and sled pulling—plus the scoring math and rule changes like limited drag passes and dyno load/traction constraints. The hosts also get into the build-and-tune grind behind the points run: dyno strategy, nitrous/boost control, drivetrain repeatability, and the kind of pit-crew logistics and repairs that decide who finishes strong.
Myer just made history at UCC 2026, becoming the first competitor to ever break the 3,000 point barrier with a total score of 3,393. This week Will sits down with Myer and guest Josh McCormack, a UCC 2025 competitor, to break down every run, every number, and every decision that went into the most dominant performance the event has ever seen.
Across three days of competition, Myer opened on the drag strip with a 4.903, followed it up with 3,620 horsepower on the Super Flow dyno to bank more than 1,200 points in that session alone, and closed out the weekend with a 355 foot sled pull. The crew breaks down the tuning decisions, the overnight chassis conversion between dyno day and sled pull day, and what it actually takes to put up competitive numbers across all three disciplines in a single weekend.
Having Josh in the room as a past UCC competitor adds real perspective to the debrief. The guys talk through what separated the top finishers from the rest of the field, why the West Coast teams dominated the leaderboard, and why pre-event testing at the drag strip and dyno is the difference between contending and just showing up. They also get into the sled pull setup, what happened on Myer's pull, and what the points game looks like when you are genuinely building toward something no one has ever done before.
This is an honest debrief from the guys who built the truck, drove it, and rewrote the record books at one of the most demanding diesel performance competitions in the country.

big power
"I mean, I mean, like I knew Cody Hawk had made big power and he's, [156.3s] you know, kind of tied into that, um, DHD crew,"
“Big power” just means the engine is making a lot more output than normal. The host is saying Cody Hawk’s setup was built to produce a lot more than stock.
“Big power” is shorthand in performance circles for significantly higher engine output than stock. Here, the host says Cody Hawk made big power, and that he had more testing and parts than others, suggesting a focus on extracting more horsepower/torque reliably.
Duramax
"So if the guys don't know, Cody Hawk brought a Duramax to compete. [163.9s] So there's Ford's Chevy's, you know, and Cummins all there competing."
Duramax is a type of diesel engine made by General Motors. The host is saying Cody Hawk showed up with a truck running that diesel engine to compete.
Duramax is GM’s name for its diesel engine family, most commonly associated with heavy-duty trucks. In this context, the host says Cody Hawk brought a Duramax to compete, meaning the competition truck is powered by a GM diesel rather than a gasoline setup.
built block
"Um, um, but yeah, Ziegler, he has a built block."
A built block means the engine internals are upgraded to survive more stress and make more power. It’s a common way racers describe an engine that’s been strengthened for performance.
A built block means the engine’s cylinder block has been strengthened or upgraded (for example, with stronger internals) to handle higher power and stress. The host ties it to Ziegler, implying his engine is prepared for big power rather than staying stock.
Ultimate Callout Challenge
"“But so for quick little recap, people that don't know ultimate call it challenge happens in Indianapolis every year.”"
Ultimate Callout Challenge is a diesel-truck event in Indianapolis. It’s not just one race—there are multiple parts over several days, and drivers earn points based on results.
Ultimate Callout Challenge is an event format for diesel trucks held in Indianapolis. It combines multiple disciplines across several days, including drag racing, and is used to determine overall points across competitors.
Indianapolis
"“...challenge happens in Indianapolis every year.”"
Indianapolis is the host city for the Ultimate Callout Challenge each year. In motorsports, it’s a major hub for racing events and diesel-truck competitions.
diesel trucks
"“It's a triathlon for diesel trucks.”"
Diesel trucks are trucks with diesel engines. Diesel engines make a lot of twisting force, and in competitions they’re often tuned to be much stronger.
Diesel trucks are heavy-duty vehicles powered by diesel engines, which use compression ignition rather than spark plugs. In performance events, diesel trucks are often modified for higher fuel delivery and boost to produce very high torque.
drag racing
"“So day one, you are doing drag racing.”"
Drag racing is racing in a straight line to see which vehicle gets up to speed faster. The results are usually based on how quickly they cover the track and how fast they’re going at the end.
Drag racing is a straight-line motorsport where two vehicles compete over a short distance to see who accelerates faster. In diesel-truck events, it’s typically measured with elapsed time and trap speed (how fast the truck is at the end).
subframe
"So for some people like Meyer, it's jacking a whole truck up and rolling a complete subframe underneath it."
A subframe is a strong metal frame inside the car that supports key parts like suspension. Swapping a subframe is a big job, but it can be used to change the car’s setup fast.
A subframe is a secondary structural frame that the main body mounts to, often carrying suspension and drivetrain components. The episode describes “rolling a complete subframe underneath it,” meaning the competitor swaps or installs a whole subframe assembly to change the vehicle’s setup quickly.
Heims
"And for other people like myself last year, it's a lot of Amazon wheel spacers and some, you know, bars with Heims on it."
Heims are joint hardware used on performance builds. They’re strong, allow movement in multiple directions, and are often used to make adjustable linkages.
Heims are spherical rod ends (often used in suspension and fabrication) that allow controlled movement while handling high loads. Here, “bars with Heims on it” suggests a custom linkage/attachment setup for the sled-pole configuration.
drag strip
"So a perfect score is 4.85 on the drag strip, 3000 horsepower and a three 295, sorry, 295 foot pole."
A drag strip is a straight track built for racing in a straight line. Cars run down it to see how fast they can go, and here it’s part of how they score points.
A drag strip is a purpose-built straight race track where cars or sleds run timed accelerations over a fixed distance. In this episode’s points system, the drag strip score is one of the inputs used to calculate total points.
horsepower
"So a perfect score is 4.85 on the drag strip, 3000 horsepower and a three 295, sorry, 295 foot pole."
Horsepower is a number that tells you how much power the engine can produce. Higher horsepower usually means the vehicle can accelerate harder, and here it’s used for scoring.
Horsepower is a measure of engine power—how much work the engine can do over time. In this episode, “3000 horsepower” is one of the scored targets in their points system.
stanced out
"And then here's a picture of it, freaking stanced out on these ridiculous axles with a trust for like just knowing that that is the exact same truck doing all this different stuff."
“Stanced out” means the truck is set up to look extra low and aggressive. It usually comes from lowering the suspension and fitting the wheels/tires so they sit just right for the look.
“Stanced out” refers to an exaggerated, low ride-height look where the suspension is lowered and the wheels sit very close to the fenders. In practice, it usually involves suspension changes and careful wheel/tire fitment to achieve the visual “stance.”
wheel spacers
"I would say it's a fan favorite because like they have to, like the, and people can go into the pits and watch these people bolted up their wheel spacers or"
Wheel spacers are parts that sit between your wheel and the car’s hub to push the wheel farther out. People use them to fit wheels/tires better or change stance, but they should be installed correctly for safety.
Wheel spacers are metal (or sometimes hub-centric) rings placed between the wheel and the hub to move the wheel outward. That can change track width and wheel fitment, but it also affects how loads are handled by the hub and studs.
sled pullers
"And then the sled pullers are like, well, you, none of you guys are real because sled pullers are it."
Sled pullers are race trucks/tractors that compete by dragging a heavy sled. Instead of racing down a track for speed, they try to pull the sled as far as possible or under a heavy load.
Sled pullers are vehicles built to compete in pulling events where a tractor or truck drags a weighted sled. The goal is typically to pull the sled the farthest or move it the most under a set load, emphasizing torque and traction rather than top speed.
P pump
"We were hitting about 1800 on the dino and we were a P pump and everybody else said these common rails."
A “P pump” is a type of diesel fuel-injection pump. It’s the part that controls how much fuel the engine gets, and different pump designs can change how easily a diesel can be tuned for big power.
“P pump” refers to a specific style of diesel fuel-injection pump used on certain older diesel engines (commonly associated with the Bosch P-pump design). In diesel performance circles, “P pump” is often treated as a distinct setup because it affects how the engine can be tuned and how much fuel it can deliver under boost.
common rails
"We were hitting about 1800 on the dino and we were a P pump and everybody else said these common rails."
“Common rail” is a modern diesel fuel system where fuel is kept under high pressure in a shared rail. The engine then uses electronics to send that fuel to the injectors, which can make tuning for power different than older systems.
“Common rails” refers to common-rail diesel fuel injection systems, where fuel is stored in a high-pressure rail and delivered to injectors electronically. In performance discussions, “common rail” setups are compared against older injection-pump designs (like “P pump”) because the hardware and tuning approach differ.
shift spike
"But yeah, I'll never forget the shift spike video or not shift spike."
A “shift spike” is what people call the sudden jump you can see when a vehicle changes gears. It can show up as a quick spike in RPM or how hard the truck feels right as the shift happens.
“Shift spike” likely refers to a noticeable spike in engine speed or power/torque during a transmission shift, often seen in performance videos or dyno/telemetry. It’s a shorthand for the moment when the drivetrain unloads/reloads as gears change, which can be especially dramatic on high-power diesel builds.
tire system
" [845.3s] Oh, we wanted to help work on our tire system because our tires were blowing up. [848.8s] So we want to fix that problem."
Your tire system is basically the tires and how they’re set up to grip the road. If the tires are “blowing up,” it means they’re failing—often from heat, pressure, or traction forces.
A tire system refers to the whole setup that determines how the tires behave, including tire choice and how they’re managed for traction. In this context, “tires were blowing up” suggests the setup was failing under the event’s loads, heat, or pressures.
dino
" [864.1s] But we've, we hit the dino in the last eight months, nine months, whatever it's been. [868.4s] I've hit the dino with three, the super flow dino with three different engines"
A “dino” is a testing machine that measures how much power an engine makes. It lets you test the same car/engine under controlled conditions so you can see what changes actually help.
“Dino” is shorthand for a dynamometer, a machine that measures engine output (like horsepower and torque) by loading the engine while it runs. Using a “super flow dino” implies they’re running controlled tests to compare different engine setups and tuning changes.
OEM
" [899.7s] Like the pistons that were in that caspist and wonder were not as good as OEM. [903.4s] I think OEM would have taken it, but some of the settings and tuning I did also [907.0s] didn't help."
OEM means “factory original” parts made for the vehicle. They’re saying the replacement pistons weren’t as good as the ones that came from the manufacturer.
OEM stands for “Original Equipment Manufacturer,” meaning the parts that came from the factory on that engine. When they say the pistons weren’t as good as OEM, they’re comparing aftermarket/alternative parts to the factory-spec components.
scattering
" [907.0s] didn't help. [907.8s] And so it ended up scattering."
“Scattering” here means the engine failed badly and internal parts got destroyed. It’s the kind of failure you’d see after something went wrong with the build or tuning.
In engine-builder slang, “scattering” usually means catastrophic internal failure—parts breaking apart and being destroyed. It’s often used when an engine lets go under stress, such as from detonation, overheating, or severe mechanical mismatch.
factory wet block
"I think part of all that dino testing, you're dino testing with a factory wet block and a cast factory style piston, which is not known to be like the most robust thing on earth."
It’s an engine design where coolant flows right around the cylinder liners. “Factory wet block” means they’re starting with the original, stock-style block instead of a more custom one.
A “wet block” is an engine block design where the coolant is in direct contact with the cylinder liners. Using a factory wet block means the base engine casting/liner setup is stock, rather than a fully custom dry-sleeve or aftermarket block.
cast factory style piston
"I think part of all that dino testing, you're dino testing with a factory wet block and a cast factory style piston, which is not known to be like the most robust thing on earth."
A cast piston is made by pouring metal into a mold. It’s usually not as strong as a forged piston, so it can be a weak point when you push the engine hard.
A cast piston is made by pouring molten aluminum into a mold, which is typically cheaper and can be less strong than forged pistons. In high-power builds, piston strength and heat tolerance matter because weak pistons can fail under high cylinder pressure and heat.
tuning strategy
"If you have a, a weak engine and you can figure out the tuning strategy, the RPM range and stuff to make it not crack the block and keep the piston alive."
A tuning strategy is the planned approach to calibrating the engine’s control systems (fueling, ignition timing, boost, and more) to achieve target power while staying within safe mechanical limits. Here, the host ties it to avoiding block cracking and keeping pistons alive across the RPM range.
RPM range
"If you have a, a weak engine and you can figure out the tuning strategy, the RPM range and stuff to make it not crack the block and keep the piston alive."
The RPM range is the span of engine speeds where the tune is expected to work safely and effectively. High-power engines can behave differently at different RPMs, so tuners often target specific ranges to prevent knock, overheating, or mechanical failure.
forge pistons
"Then when you put those forge pistons and that, that deck plate and all that really strong hardware in there."
Forged pistons are made by shaping metal under high pressure, which typically produces stronger, more durable pistons than cast versions. In boosted/high-horsepower builds, forged pistons help resist cracking or deformation under high cylinder pressure.
deck plate
"Then when you put those forge pistons and that, that deck plate and all that really strong hardware in there."
In engine-building talk, a “deck plate” usually refers to a structural component used to support or reinforce the engine’s top end (often related to cylinder head/block sealing and stability under high boost). It’s part of the “strong hardware” the host contrasts with weaker stock components.
rev this thing out
"Do we rev this thing out in third, or do we finally grab overdrive? And we kind of made the call of, if I can take a cast, piston wonder to 58, 6,000"
To "rev it out" means to spin the engine faster and higher in RPM before shifting. That can help power, but it also puts more stress on engine parts.
To "rev this thing out" means to run the engine at high RPM up to (or near) its shift point or redline. Higher RPM can keep the engine in its power band, but it also increases stress on components like pistons, valves, valve springs, and the clutch/transmission.
cast piston
"And we kind of made the call of, if I can take a cast, piston wonder to 58, 6,000 on the drag strip, this freaking diamond piston, 64 should be able to do it."
A cast piston is an engine piston made by pouring metal into a mold. Different piston types can handle heat and stress differently, which matters when you’re pushing the engine hard on a drag strip.
A cast piston is made by pouring molten aluminum into a mold, which generally makes it less expensive and can be suitable for certain builds. In high-RPM drag applications, piston choice affects durability and how well the engine survives repeated pulls, especially when paired with the right valve-spring and RPM limits.
diamond piston
"And we kind of made the call of, if I can take a cast, piston wonder to 58, 6,000 on the drag strip, this freaking diamond piston, 64 should be able to do it. No problem."
"Diamond piston" is a brand of performance pistons. Here, they’re talking about using that piston to survive higher RPM and still make the car fast on the drag strip.
"Diamond piston" refers to a specific piston brand/model line (Diamond Pistons) known in performance circles for forged piston offerings. In this context, the speaker is comparing durability expectations between piston setups while planning RPM and shift strategy for drag racing.
power band
"Maybe we can bring the engine back down into the power band a little bit more, it'd be more efficient on doing shifting into overdrive. But this was a, this was a longevity game."
The "power band" is the part of the RPM range where the engine feels strongest. Shifting to keep the engine in that zone helps the car keep pulling hard.
The "power band" is the RPM range where an engine produces its strongest usable power and torque. Drag-racing shift decisions aim to keep the engine operating in that range so each gear change makes the car accelerate instead of falling off.
longevity game
"But this was a, this was a longevity game. Like I didn't want to hurt an engine or a clutch or transmission or whatever is going into overdrive."
They’re describing this as a "longevity game," meaning they wanted the car to last through the event. So they chose a safer RPM/shift plan instead of pushing it to the absolute limit every time.
The speaker frames the strategy as a "longevity game," meaning the goal is not just peak speed but surviving repeated runs without damaging the engine, clutch, or transmission. This changes how aggressively they push RPM and shift timing compared to a one-off qualifying pass.
clutch
"Like I didn't want to hurt an engine or a clutch or transmission or whatever is going into overdrive."
A clutch is what lets the engine power get transferred to the transmission. If you’re racing hard, the clutch can wear out or overheat, so the strategy has to protect it.
A clutch is the friction device that connects and disconnects engine power from the transmission. In drag racing, clutch wear and heat can become a limiting factor, so shift/RPM strategy is often chosen to avoid overheating or damaging the clutch while still staying fast.
valve float
"Um, which played with lighter valve springs before and experienced valve float on some of those cast piston motors. And so our valve spring game was, I would say above whale above average, I"
Valve float is when the engine revs so high that the springs can’t control the valves anymore. The engine can lose power and, in worst cases, the valves can get damaged.
Valve float happens when the engine spins so fast that the valve springs can’t keep the valves following the camshaft accurately. The result is loss of control over valve timing (often a power drop) and increased risk of contact damage between valves and other components.
valve spring
"Um, which played with lighter valve springs before and experienced valve float on some of those cast piston motors. And so our valve spring game was, I would say above whale above average, I"
Valve springs are parts that help control the engine’s valves. At high RPM they have to keep everything moving correctly—if they can’t, the engine can start to misbehave or get damaged.
Valve springs help keep the engine’s valves closed and control valve motion at higher RPM. When RPM climbs, springs must maintain proper valve timing and prevent float; otherwise the valves can lose contact with the cam profile, risking power loss or even engine damage.
valve trim
"I honestly think our valve trim would've been safe to 7,000. No problem."
“Valve trim” sounds like a tuning tweak for how the valves are set up to open and close. They’re saying their valve settings were probably safe up to about 7,000 RPM.
“Valve trim” here appears to refer to a tuning adjustment related to the engine’s valve setup—often meaning changes to valve lift/timing or related calibration that affect how the engine breathes. The speaker is implying that their valve-related setup would have been safe up to a certain RPM.
forged piston
"It's really the first time I really had gone anywhere with a, a good, you know, deck plate billet, like a forged piston and it was an awesome feeling."
A forged piston is a stronger piston made by pressing metal into shape. When an engine is tuned for more power, the extra stress can break weaker pistons, so forged ones are often used.
A forged piston is a piston made by shaping metal under high pressure, which typically results in a stronger, more durable part than many stock cast pistons. In high-boost or high-RPM builds, forged pistons help resist cracking or deformation under extreme cylinder pressures.
stock pistons
"But I think that learning came from a year of playing with stock pistons, lighter valve springs stock valve."
“Stock pistons” are the factory-produced pistons that come in the engine from the manufacturer. In tuning, comparing stock pistons to forged or upgraded pistons helps determine how much cylinder pressure and RPM the engine can safely handle.
stock valve
"But I think that learning came from a year of playing with stock pistons, lighter valve springs stock valve. I mean, that's another reason we don't have as big of valves as some of these gys because we've been able to get so much power and airflow on a stock sized valve that we don't need to go as big."
“Stock valve” means the factory valve size and design rather than a larger aftermarket valve. The speaker argues they can make strong power and airflow even with stock-sized valves, which affects how much they need to upgrade the valve train.
airflow
"I mean, that's another reason we don't have as big of valves as some of these guys because we've been able to get so much power and airflow on a stock sized valve that we don't need to go as big."
In engine tuning, “airflow” refers to how much air the engine can move into the cylinders. More effective airflow (through intake/exhaust and valve sizing) generally supports higher power potential, especially when paired with the right fuel and ignition calibration.
waggler engine
"But I mean, it was awesome. You had your waggler engine that you'd put all his big down, hits through and you decided to refresh it."
“Waggler engine” appears to be a nickname for a specific engine build or setup used by the group, rather than a widely standardized technical term. The context suggests it’s an engine they had previously built and then refreshed.
honing strategy
"the honing strategy and the sleeve press and things like that."
Honing is like precision sanding inside an engine cylinder. A “honing strategy” means they choose the exact method so the cylinder surface is just right for the engine parts that will run inside it.
Honing is the controlled process of finishing the inside of a cylinder bore to get the right surface texture and geometry. A “honing strategy” is the specific plan for how that honing is done (abrasive choice, pattern, and targets) to match the sleeve and piston/ring setup.
sleeve press
"the honing strategy and the sleeve press and things like that."
A “sleeve press” is the tool/process used to put a cylinder liner into an engine block. Pressing it in correctly helps it seal well and stay stable over time.
A sleeve press refers to the press-fit process used to install an engine cylinder sleeve (a replaceable cylinder liner). The press operation controls how tightly the sleeve seats, which affects sealing, heat transfer, and long-term durability.
35 spline input shaft
"We snapped a 35 spline input shaft. Oh yeah."
The input shaft is a drivetrain part that transfers power from the engine into the transmission. “35 spline” means the shaft has a specific tooth pattern that locks it to the matching part, and in this case it broke under the testing loads.
An input shaft is the transmission component that receives torque from the engine and sends it into the gearbox. “35 spline” describes the number of spline teeth on the shaft, which mate to a matching part (like a clutch or gearbox input) and determine how torque is transmitted—more splines can mean more engagement area, but the shaft can still fail if loads exceed its strength.
Vegas testing
"And that drag that 35 spline had Vegas testing on it, which was three passes and like three or four dinopoles."
“Vegas testing” sounds like a specific test session the team did previously, likely in Las Vegas. They’re saying the part had already been tested on a few runs before it broke.
“Vegas testing” appears to be a shorthand for a specific test session or event the team runs in Las Vegas (or a branded testing program associated with that location). The key idea is that the 35-spline input shaft had already been through a limited set of prior test passes before failing again.
diesel scene
"And so he he got into the diesel scene wanted to kind of make more power."
“Diesel scene” just means the group of people who are into diesel engines. They often modify them to make more power than the factory setup.
“Diesel scene” refers to the enthusiast subculture around diesel engines, especially people who modify them for more power. In this context, it’s about chasing higher output from a diesel platform rather than stock performance.
seat belts
"...he was just finding like dual plated places for like the seat belts and stuff and just like drilling the weld nuts out or weld like where you spot welds out of it to get the plate to fall off."
Seat belts are what keep you from flying forward in a crash. In racing, people sometimes change the mounting hardware to save weight, but it has to stay safe and legal.
Seat belts are restraint systems that keep occupants secured during acceleration, braking, and impacts. In motorsport weight-reduction work, people may remove or relocate related mounting hardware, but doing so must still meet safety rules for the event.
spot welds
"...drilling the weld nuts out or weld like where you spot welds out of it to get the plate to fall off."
Spot welds are small, localized welds used to join sheet metal panels. For weight-reduction or fabrication, removing spot-welded sections can allow parts to be taken off cleanly, but it may require rework or reinforcement afterward.
pulling the trans
"I mean, I was barely back and the truck was in the air. We're pulling the trans. Like I look at the data, like they start pulling it."
“Pulling the trans” means removing the transmission from the vehicle to inspect or repair internal damage. After an input-shaft failure, the transmission often has to come out so the broken parts can be replaced and the driveline checked.
sensors
"And cause we have a good amount of data on that trans in like sensors and stuff. And I look at it. I'm like, like, this doesn't make sense, but I think the 35 spine snapped."
“Sensors” here refers to instrumentation used to monitor transmission behavior and other drivetrain signals. The speaker says they had “a good amount of data” from sensors, which they used to infer the likely internal failure before the transmission was removed.
input shaft snapped
"Sure enough, took it out. Input shaft snapped. Cool. Swap it out, put it back in."
The input shaft is a key spinning part inside the transmission that connects to the engine. If it “snapped,” it broke, so the transmission can’t transfer power anymore. That kind of failure usually happens fast and can cause other parts to get damaged.
The input shaft is the transmission’s front shaft that receives rotational power from the engine. When the “input shaft snapped,” it means the shaft fractured under load, which typically causes sudden loss of drive and can scatter transmission parts.
test and tune window
"Swap it out, put it back in. We had like a 54 hour test. Four hour, four hour test and tune window. We hit it pretty early, like 120 or something in the morning or one."
A “test and tune window” is a block of time where you try the car/truck, check how it’s behaving, and make adjustments to get it working right. Here, they’re saying they had a few hours to test and dial things in after fixing the transmission.
A “test and tune window” is a scheduled period to run the vehicle, evaluate results, and adjust settings to improve performance or drivability. The speaker mentions a “four hour… test and tune window,” implying they were iterating quickly after the repair.
ECMs
"Ultimately, this is what sucked about Drag Race Day is what we were fighting a bunch of issues that I thought we, we, we swatched, we switched ECMs. We went from an 849 to a Bosch in the 849."
An ECM is the engine’s computer. It decides things like how much fuel to inject and when to spark, so changing it can change how the car runs—especially when you’re trying to launch hard.
ECM stands for Engine Control Module, the car’s computer that manages fueling, ignition timing, and other engine parameters. Swapping ECMs can change how the engine responds to nitrous, boost, and throttle input, which can dramatically affect launch consistency.
Bosch
"We went from an 849 to a Bosch in the 849. I was doing some things to get the boost up on the line. That way the moment you left the button, it was ready to make some power to"
Bosch is a company that makes automotive electronics. Here, it sounds like they swapped to a different engine computer so the car would respond differently during the race.
Bosch is a major automotive electronics supplier, and in this context it likely refers to an aftermarket or alternative engine management unit/ECM used for tuning. Switching to a Bosch controller can change calibration behavior—how the engine reacts to nitrous, boost, and launch control inputs.
boost
"[1541.9s] Guys, some numbers. [1542.5s] So normally you're leaving mid 20 pounds of boost, maybe 14. [1547.9s] I'm leaving at 14 and that with the 849 normally."
Boost is extra pressure that forces more air into the engine. More air usually means more power, so changing boost changes how hard the car accelerates.
Boost is the extra air pressure forced into the engine (typically by a turbocharger or supercharger) to increase how much oxygen the engine can burn. The speaker is comparing boost levels (mid-20s pounds vs 14 vs “lucky to get 10”) to explain why their launch and acceleration weren’t matching expectations.
popping and sputtering
"[1574.0s] a little bit different than what I could do with the 849, it didn't take it. [1576.8s] It was popping and sputtering really bad and it just coughed off the line."
That phrase describes the engine running rough—like it’s not burning the fuel cleanly. When it happens, the car can hesitate or stumble when you launch.
“Popping and sputtering” describes rough combustion—often from misfires, unstable fueling, or ignition/timing issues. The speaker links it to the timing change not matching what worked on the other setup, and it results in the car “cough[ing] off the line.”
timing
"we put the timing back to the timing back, at least close to [1602.5s] like a safe number because you put the timing too low, especially with nitrous coming in, like it cools down the burn."
“Timing” is when the engine lights the air-fuel mixture. If it’s set too early or too late—especially when using nitrous—the fuel may not burn correctly, which can cause popping or rough running.
In this context, “timing” means ignition timing—when the engine’s spark occurs relative to piston position. With nitrous, timing that’s too low can prevent the fuel from burning fully before the nitrous-related conditions change, leading to popping/backfiring.
injection vent
"it doesn't give the fuel enough time to burn and it'll [1612.9s] pop because the injection vent didn't happen soon enough for the burn to [1616.0s] actually happen what it was supposed to."
This is about when the engine’s injection system actually releases the injected gas/fuel. If it doesn’t happen soon enough for the engine’s current conditions, the mixture can fail to burn properly and you can get popping.
“Injection vent” is the moment/behavior of the nitrous (or fuel) injection system where the injected charge is delivered. If that delivery happens too late relative to the combustion event, the mixture won’t burn as intended, which can cause popping.
induction hardened head
"Cause it's an induction hardened head. And so there's, you know, there's an, a seat that's all perfect."
Induction hardening is a way of making the cylinder head’s surface tougher. It helps the valve contact area wear less, which matters when the engine is pushed hard.
An induction-hardened cylinder head is heat-treated using electromagnetic induction so the metal surface becomes much harder and more wear-resistant. This helps the valve seating surfaces survive repeated opening/closing and high heat/pressure conditions, especially in racing or high-output engines.
valve seating area
"And then I, uh, I set the, the valve seating area a little bit narrow. And as it wears, the seat gets wider and it kind of work hardens a little bit and gets, yeah, but yeah, it's just, just, just moves a little bit at first."
The valve seating area is where the valve seals against the head to keep combustion gases from leaking. If it’s set up right, it can wear in to a better sealing fit over time.
The valve seating area is the contact surface where the engine’s valve seals against the cylinder head. Its width/shape affects sealing quality and wear, and in this discussion it’s being intentionally set narrow so it “wears in” to the final working geometry.
work hardens
"And as it wears, the seat gets wider and it kind of work hardens a little bit and gets, yeah, but yeah, it's just, just, just moves a little bit at first."
Work hardening means the surface gets tougher after it’s been rubbed and loaded repeatedly. For valve seats, that can help them last longer when the engine is driven hard.
Work hardening (strain hardening) is when a metal becomes harder due to plastic deformation from repeated contact and friction. In valve seats, controlled wear can increase surface hardness so the seat holds up better under sustained high load.
seat flows more
"Well on a race gas engine, they make the seat 30,000 wide because a 30,000 seat flows more, because it's just got a tiny little pinch point."
This is about how easily air (or exhaust) can move past the valve. A certain seat shape can let more flow through, but it has to be durable enough for the engine’s output.
“Seat flows more” refers to how the valve seat geometry affects airflow through the intake/exhaust port. A narrower seat can create a smaller restriction (“pinch point”), improving flow, but it can also reduce durability if the seat is asked to handle extreme power.
race gas engine
"Well on a race gas engine, they make the seat 30,000 wide because a 30,000 seat flows more, because it's just got a tiny little pinch point."
A race gas engine is an engine tuned to use racing fuel. The speaker is comparing how valve seats are sized for racing versus other high-power setups.
A race gas engine is built to run on racing fuel, typically allowing more aggressive tuning and higher combustion performance than pump gas. Here it’s used to contrast valve-seat sizing: a narrower seat can improve flow, but it must still survive the engine’s power and heat.
toe width
"And, but I don't want to start at a toe width because you're giving up flow for, for nothing, you know, it's just like, so that's kind of where you're playing"
Toe width is about whether your tires point slightly toward each other or slightly away from each other. That small angle can change how the car turns and how quickly the tires wear.
Toe width refers to how much the tires are pointed inward or outward relative to the vehicle’s direction of travel, often discussed as a setup choice that affects steering response and tire wear. In racing, changing toe can trade off straight-line stability versus turn-in feel and grip consistency.
nitrous changes
"I just kind of made some basic tuning changes, um, nitrous changes,"
Nitrous is a power-boost system. “Nitrous changes” means they adjusted how the boost is used—like how much and when—so the car accelerates harder without losing traction or stressing the engine.
Nitrous changes refers to adjustments to a nitrous oxide system, typically involving how much nitrous is added and when it’s activated. Because nitrous dramatically increases power, tuning it affects traction, acceleration consistency, and whether the engine stays within safe operating conditions.
lean spot
"And it wasn't even, it was a, and remember it had that crazy lean spot. [1896.1s] Yeah."
A “lean spot” means the engine had too much air compared to fuel for a brief moment. That can make the car stumble or feel weak, and it can be hard on the engine if it happens badly.
A “lean spot” is a moment where the air-fuel mixture is too lean (not enough fuel relative to air). In drag racing, a lean condition can cause hesitation or bogging and can also be risky for engine health if it’s severe or prolonged.
mile an hour
"John was really happy with your mile an hour. [1909.3s] Yeah. [1909.5s] He's like, Oh, you guys are putting on some power."
“Mile an hour” is the car’s top speed at the end of the drag run. Higher trap speed usually means the car made more power and used it effectively.
“Mile an hour” here refers to trap speed—the speed measured at the end of the quarter-mile run. Trap speed is strongly tied to overall power and efficiency, and it helps interpret whether an ET was limited by launch/traction or by power.
499
"And so you've been 499 at 146. [1917.1s] And so you've been 499 at 146."
“499” is drag-racing shorthand for an elapsed time just under five seconds in the quarter-mile. It means the run was extremely fast.
“499” is shorthand for a sub-5.00-second quarter-mile elapsed time (ET), commonly used in drag racing to describe how fast the car runs. It indicates the car is very close to the “five-second” barrier, which is a major milestone for many builds.
60 foot
"Like the right way to go fast is have a good 60 foot. Like anyone could just throw power at the back end, but it's hard on everything."
In drag racing, “60-foot” is how fast the car gets to 60 feet from the start. It matters because the first part of the run is where traction and launch control make the biggest difference.
In drag racing, the “60-foot” time is how long the car takes to reach 60 feet from the start line. It’s a key indicator of launch quality—traction, clutch/launch technique, and how well the car hooks up early.
153 miles an hour
"that was a one 40, four 60 foot at five 14 with one 153 miles an hour. And that's just cause it was a dog out of the hole."
“153 miles an hour” is how fast the car was at the end of the run. It’s a big number, but the host is saying the start and acceleration still mattered more for what happened overall.
“153 miles an hour” is the terminal speed reported at the end of the run (typically at the quarter-mile mark in drag racing). It’s a speed metric, but the host is contrasting it with launch/acceleration issues that hurt the overall run.
dog out of the hole
"And that's just cause it was a dog out of the hole. Just you had no boost because not only when I let off the button"
“Out of the hole” means right when the car launches off the start. “Dog out of the hole” means it didn’t get going well at the beginning.
“Out of the hole” refers to the launch phase right after the start line in drag racing. Calling it a “dog out of the hole” means the car was slow to get moving, usually due to traction, tuning, or power delivery timing.
map
"Just you had no boost because not only when I let off the button, it went to a different part in the map and it like almost cut nitrous for the first little bit"
A “map” is the computer’s settings for how the car should run—like how much fuel and power to make. If it switches to a different setting at the wrong time, the car can feel slower or inconsistent.
In performance tuning, a “map” is the engine control strategy (fuel, ignition, boost targets, and nitrous timing) stored in the ECU. The host is saying the car switched to a different tune segment, which affected when nitrous came in and how quickly boost built.
505
"There's a third fast because poor boys did a 505. And so you're in third position after your first round with a five 14"
“505” is a quick way to say someone ran about 5.05 seconds in the race. It’s basically a time number used to compare who’s faster.
“505” is shorthand for a drag-racing elapsed time of about 5.05 seconds (often written as 5.0x). It’s used to compare how fast different cars run in the same event or round.
five 14
"And so you're in third position after your first round with a five 14, which I mean, I know a lot of people would have been super thrilled"
“Five 14” is a time—about 5.14 seconds—used in drag racing to show how fast the run was. It’s the kind of number racers compare to see who’s ahead.
“Five 14” is shorthand for an elapsed time around 5.14 seconds, commonly used in drag racing results. The host is using it to describe their performance relative to other runs in the event.
launch
"we need to, we need to make safe power, but we need to add some power. ... We need to fix the launch, but we can't go."
The launch is how the car gets moving right at the start. If the launch is bad, the tires can spin instead of accelerating hard.
In drag racing, “launch” refers to the initial acceleration off the line—when traction, throttle control, and power delivery determine whether the car hooks up or spins. The host says they need to fix the launch, meaning the car wasn’t transferring power to the ground reliably.
PSI
"boost was above my 12 pounds or whatever I set. ... I think it was 13 pounds."
PSI is a way to measure pressure. Here it’s used to say how much boost pressure the turbo is making.
PSI (pounds per square inch) is a unit of pressure. In turbo/nitrous drag racing, PSI is commonly used to describe how much boost pressure the engine is running at.
instant 360 camera
"It's a visual reminder. ... Like do not do anything until that light turns green. ... and you were looking around on that instant 360 camera."
An instant 360 camera is a 360-degree action camera setup used to capture the driver’s perspective and surrounding area during a run. In racing, that footage helps analyze what the car did at launch and during the run (e.g., throttle behavior, wheel movement, and staging/launch technique).
limiter
"I was like, dude was, I was like, I was on the limiter and I was like, okay, like auto shift is on."
A limiter is a safety setting in the car’s computer that prevents the engine from going past a safe limit (like too high RPM). When you’re “on the limiter,” the car is basically holding you back to protect the engine.
A limiter is an ECU (engine computer) protection feature that caps something like RPM or throttle/boost so the engine can’t exceed safe limits. When the host says they were “on the limiter,” they mean the car’s control system was actively restricting output while they were testing.
auto shift
"okay, like auto shift is on. The kits are armed."
Auto shift means the car changes gears for you automatically. It’s often used to make runs more consistent when you’re testing or tuning.
Auto shift is a drivetrain control mode where the car automatically commands gear changes instead of the driver doing it manually. In a tuning/data-logging context, it helps keep launches and shifts consistent so AFR/boost behavior can be evaluated accurately.
got lean
"We noticed that it got lean and, um, right, right after you left the button, it got lean, which that's what normally does."
“Lean” means the engine has more air than fuel for the amount of boost/load. That can be risky because it can run hotter and potentially cause damage if it happens too early or too much.
“Lean” means the engine’s air-fuel mixture has too little fuel relative to air. Leaning out under boost can raise combustion temperatures and stress components, which is why the host is concerned it happens “way sooner than it should have.”
AFR sensor
"So I have an AFR sensor and the way with mine, with my tuning and the way I've done it in the past, like on my Vegas pass, that was a 4.99."
An AFR sensor tells you how much fuel is being used compared to air. If the mixture is “lean,” there’s relatively too little fuel; if it’s “rich,” there’s relatively too much fuel.
An AFR sensor measures the air-fuel ratio in the exhaust, which tells the ECU whether the mixture is rich (more fuel) or lean (less fuel). The host uses it to confirm when the engine goes lean earlier than expected during a boost/nitrous sequence.
turbo spooled
"It's, it's rich at first to get the turbo spooled. And once it's spooled, it makes boost, nitrous comes on, boosts there."
When the turbo is “spooled,” it’s spinning fast enough to start making boost. Before it’s spooled, the engine may need different fueling to get the turbo up to speed.
“Turbo spooled” means the turbocharger has reached enough speed to produce significant boost pressure. The host describes a typical sequence: rich mixture at first to spool the turbo, then boost builds and the fueling strategy changes.
pro street drag race file
"So you started with my pro street drag race file and I leave the line at 3400 RPM. You leave the line at 2800."
A “pro street drag race file” is a saved computer tune meant for drag racing. It’s designed to help the car launch and accelerate, but if it doesn’t match your setup, it can cause problems like running lean early.
A “pro street drag race file” is a pre-made ECU calibration strategy intended for drag racing use—typically optimized for launch, boost/spool behavior, and acceleration runs. The key point here is that the base tune’s launch/spool fueling targets may not match the car’s setup, so logs can reveal issues like going lean too soon.
air quantity
"there's a smoke map in the tuning that like kind of says like at this fuel quantity or this air quantity, allow this much fuel or whatever."
“Air quantity” is how much air the engine is pulling in. The ECU uses that to decide how much fuel to add; if it doesn’t add enough fuel for the air, the engine runs lean.
“Air quantity” is a measure of how much air the engine is ingesting (often inferred from airflow sensors or calculated load). Fueling tables that reference air quantity adjust how much fuel is allowed so the mixture stays within targets—too little fuel for the air makes the mixture lean.
fuel quantity
"there's a smoke map in the tuning that like kind of says like at this fuel quantity or this air quantity, allow this much fuel or whatever."
“Fuel quantity” means how much fuel the engine computer is telling the engine to inject. If the tune limits that too early, the engine can run lean and respond slower.
“Fuel quantity” is the ECU’s commanded amount of fuel for a given operating condition. When a smoke map ties allowed fuel to fuel/air quantity, changing those relationships can cause the engine to cut fuel too early, creating lean conditions during spool-up.
spool in
"someone had at some point selected the cells that you launch in or spool in and add a 30% and there was a huge 30% drop everywhere else."
“Spool in” means how fast the turbo builds boost after you hit the gas. If the tune cuts fuel too much during that moment, the car can feel like it’s slow to get going.
“Spool in” describes how quickly a turbocharger (or similar forced-induction system) builds boost after you apply throttle. If fueling is cut too aggressively during the spool-up window, it can delay the engine’s response and reduce acceleration right off the line.
30%
"someone had at some point selected the cells that you launch in or spool in and add a 30% and there was a huge 30% drop everywhere else."
The “30%” is a tuning change—basically the ECU was told to add or subtract a big chunk of fuel. Big percentage changes can make the car run too lean and feel delayed when you launch.
The “30%” refers to a calibration offset applied to fueling table cells, which then caused a large reduction elsewhere. In ECU tuning, percentage changes can have big effects on transient fueling (like launch), leading to lean conditions and delayed spool-up.
time slip
"[2274.5s] I knew it could do so much more. [2276.8s] I looked at the time slip, but I was a 134 60 foot. [2279.1s] I was like, of course, like my one of my slowest 60 foot ever would be the"
A time slip is the paper/printout the track gives you after your run. It shows how fast you went and split times like the first 60 feet.
A time slip is the official printout from a drag strip that lists your run results, including elapsed time (ET) and split times like 60-foot. It’s how drivers compare launches and performance run-to-run.
parachute
"[2310.1s] I mean that, that was showing. [2311.4s] And he had a parachute, which is pretty cool too. [2314.1s] Over 3000."
A parachute is a drag-race safety device that helps slow the car down at the end of the run. It’s used when the car is going too fast for brakes alone to be enough.
A drag-racing parachute is a safety and deceleration device deployed at high speed to help slow the car down before the end of the track. It’s especially common on high-speed, high-power cars where normal braking may not be enough to stop safely.
rule change
"[2315.9s] And over 3000 horse power. [2317.5s] That's something else, which I'm not going to get into the nitty gritty of it, [2320.9s] but there was a rule change that most of us weren't aware of."
A rule change in racing can alter what setups are allowed (or how they’re interpreted), which can force teams to adjust tuning, parts choices, or strategy. Even if the change is small, it can affect competitive performance because drag cars are highly optimized for specific constraints.
Toyota A90
"going down again. And so he, I asked for a 90 He's been fighting some cylinder head valve tulip bean problems over the past"
The Toyota Supra is a sports car made for fast driving. It’s sometimes talked about in terms of engine problems, especially involving the cylinder head and valves. That matters because it can affect how reliable the car is and how expensive repairs might be.
The Toyota Supra is a performance sports coupe known for its strong engine and tuning potential. In a podcast context, it may come up when discussing engine reliability or specific internal issues—like cylinder head valve-related problems—because those topics matter when modifying or maintaining high-performance cars. It’s often discussed as a platform people build for power while trying to keep the engine healthy.
overdrive
"Overdrive every time he was having overdrive problems. [2572.7s] I walked over there, the overdrive, so we're just not happy."
Overdrive is a higher gear in the transmission that lets the engine run at lower RPM for the same speed. If it’s having problems, the car may not shift or stay in that gear correctly.
In a transmission, overdrive is a gear ratio that makes the engine spin slower than it would in direct drive at the same road speed. In racing or track use, “overdrive problems” usually means the gearbox can’t hold that ratio reliably, which can hurt lap time and drivability.
valve when they originally built that engine
"So I don't think that that, um, cause he had a freedom build engine and they built good engines, but I don't think that when they originally built that engine, that's their specced 7,000 RPM."
They’re talking about whether the engine was built with the right valve parts for the kind of high-RPM use they’re aiming for. If it wasn’t, the engine can struggle to perform as intended.
This phrase is part of a discussion about how an engine is “specced” (specified) for certain performance targets. In context, it’s about whether the engine’s valve-related hardware was designed for the stated RPM and how that affects reliability and consistency.
7,000 RPM
"I don't think that when they originally built that engine, that's their specced 7,000 RPM. [2595.3s] Valvetrain set up my crap for all of it."
RPM is how fast the engine spins. At around 7,000 RPM, the engine has to control the valves very precisely, and the wrong parts or setup can limit how safely it can run.
RPM is engine speed, and 7,000 RPM is a high operating point where valve control becomes critical. The discussion implies the engine’s valve-spring/valvetrain hardware may not be specified or tuned to safely sustain that speed.
valvetrain
"Valvetrain set up my crap for all of it. [2597.4s] So that's how you still in the seven millimeter stems..."
The valvetrain is the set of parts that control the engine’s valves. If it’s not set up for high RPM, the valves may not follow the cam timing properly.
The valvetrain is the collection of components that operate the engine’s valves—commonly including springs, retainers, lifters/rockers, and related hardware. When the host says the “valvetrain set up” isn’t right for the target RPM, they’re pointing to valve control limits that can cause float or instability at high engine speeds.
7 millimeter stems
"So that's how you still in the seven millimeter stems, which a lot of the, um, the big, um, freedom engines, they put eight or a 5 sixteenths valve when they're doing the big RPM."
The valve stem is the part of the valve that the spring works against. The stem size matters because it changes how the valve and spring assembly behaves at high engine speeds.
The valve stem is the part of the valve that the spring sits on and that guides the valve’s movement. Stem diameter (here, “7 millimeter stems”) affects how the valve and spring package fits and how much material and stiffness you have for high-RPM control.
8 or a 5 sixteenths valve
"which a lot of the, um, the big, um, freedom engines, they put eight or a 5 sixteenths valve when they're doing the big RPM. [2606.3s] So the stem's thicker..."
They’re talking about using bigger valves for high-RPM driving. Bigger valves can help the engine breathe better at speed, but the rest of the valve setup has to be built to match.
This refers to valve size (diameter) used in higher-RPM performance builds. Larger valves can flow more air/fuel at high engine speeds, but they also require matching hardware (springs, stems, retainers) so the valvetrain can control the valve reliably.
running order
"You guys have drivers meeting you pick, you get the running order."
Running order is just the order of who goes first, second, third, etc. In racing, that order can matter because conditions and timing can change as the event goes on.
Running order is the sequence in which drivers/entries go during a timed event or competition session. It matters because track conditions, traffic, and strategy can change over time, so going earlier or later can affect results.
relief valve
"Cause the first hit was like 2600 when the relief valve blew open and we plugged that and away we went."
A relief valve is a safety device that opens if pressure gets dangerously high. When it opens, it can change how the car is running because the system has to relieve that pressure.
A relief valve is a safety valve that opens when system pressure gets too high. In a racing context, it can be tied to how boost/pressure is managed, and when it “blows open” it can interrupt the pressure you’re trying to run until the issue is corrected.
year of carnage
"So you did 31 100 and everybody else had to chase and your year for one reason or another was the year of carnage."
“Year of carnage” is slang for a season where lots of cars broke or failed. The idea is that it wasn’t just about driving—cars were getting wrecked by problems.
“Year of carnage” is a motorsport slang phrase meaning a season/event where many cars suffered failures or breakdowns. It’s used here to explain why other competitors couldn’t match the record—because reliability issues were widespread.
