Brand

6XD Gearbox

They’re the sponsor here, and the name suggests they make or support gearbox/transmission parts. It’s worth checking them out because sponsors like this usually have something performance-related to offer.

Topic

Road America

Road America is a well-known road course in the U.S., and it’s used here as the setting for discovering Pancho Weaver. For listeners, it helps to know that this is the kind of venue where serious racing cars and fabrication work show up.

Brand

Parnelli Jones

Parnelli Jones was a famous race driver. The host is using him as an example of the kind of big-name racing culture that was around Weaver’s family.

Brand

Dan Gurney

Dan Gurney is named alongside other legendary drivers, reinforcing that Weaver’s father was connected to top-tier racing figures. This helps listeners place the story in a historical motorsports network rather than a casual local scene.

Brand

Carol Shelby

Carol Shelby was a legendary figure in American racing and performance cars. Mentioning him suggests Weaver’s dad was connected to influential people who shaped how race cars are built.

Concept

TransM class

They’re referring to the Trans Am racing class. It’s a set of rules for what kinds of cars can race and what safety equipment they must have, but it still leaves room for teams to build and improve their cars.

Topic

innovation is welcome in this class

They’re talking about whether racing rules allow teams to experiment. The point is: some series are very strict, but this one is described as more open to new ideas.

Concept

safety standards and rules

Even when racing allows creativity, there are rules meant to keep people safe. Those rules usually cover how the car is built and what safety gear it must have.

Concept

cookie cutter kind of class

They mean a racing series where everyone builds the same kind of car. Here, they’re saying Trans Am isn’t like that—it lets teams try different approaches.

Concept

technology helps drive all that

They’re saying racing gets better as technology improves. Better brakes, engines, tires, and aerodynamics all help the car go faster and handle better.

3 Three Wheeler
Car

3 Three Wheeler

A three-wheeler is a vehicle that has three wheels instead of four. Because it has fewer wheels, it can handle and feel different than a normal car. The podcast is likely setting up a deeper explanation of how it works or why it’s notable.

Concept

Road race, GT1 type class car

“GT1 type” is shorthand for a high-performance grand touring-style race category. In practice, it usually implies a focus on aerodynamic efficiency, cooling capacity, and chassis setup to handle sustained cornering speeds—more like endurance/GT racing than short sprint touring-car racing.

Concept

chassis program

A chassis program is the development effort focused on the race car’s structure and dynamics—things like frame design, suspension geometry, stiffness, and how the car transfers loads. In racing, the chassis is often the foundation that determines how well the engine and aero can actually perform on track.

Concept

generation three weaver

“Generation three” indicates an iterative design evolution—major updates to the race car’s architecture and/or systems compared with earlier versions. Calling it a “Weaver” generation suggests the guest’s own development lineage and a structured approach to improving performance and integration over time.

Concept

cost about $100,000 less than the competitors

He’s talking about building a race car for less money than other teams. In racing, spending less can mean smarter design choices so you still get good performance.

Term

sound of the engine

He’s emphasizing that the car should sound impressive. In racing, exhaust and engine tuning can change the noise you hear.

Term

180 degree header system

A header is part of the exhaust that collects gases from the engine and routes them into the rest of the exhaust. A “180 degree” setup means the pipes are shaped to turn gases in a specific way, which can change both performance and the sound you hear.

Concept

tight constraints (for building a race exhaust)

Race parts aren’t just designed on paper—they have to physically fit in the car. “Tight constraints” means there’s very little room or flexibility, so building the part takes more work.

Term

paint scheme

A paint scheme is the specific color layout and graphics pattern used on a race car. In motorsports, it’s part of branding and fan recognition, and it can become “iconic” when repeated across seasons.

Brand

Menard yellow

Menard yellow is a bright yellow color tied to the Menards brand. Race teams often use sponsor colors so people can recognize them quickly.

Brand

STP

STP is a brand that has sponsored racing for a long time. When you see “STP” on a race car, it usually means that company was a sponsor.

Concept

test day (development and learning)

A test day is when a race team goes out to try the car and learn what works. They drive it hard to find problems and improve the car before real races.

Topic

Virginia test day

They mention a test session in Virginia where the team worked on the car. It’s part of the story of how the car was developed.

Concept

all-round tube construction (round tube chassis)

Instead of building the frame from square tubes, they used round tubes. Round tubes usually handle twisting forces better, which helps the car stay more stable under load.

Term

miter joint

A miter joint is a connection where two pieces are cut at angles (like a corner) so they meet at a specific angle before welding. In square-tube frames, frequent angle changes can require more miter joints, which can add weld complexity and potential weak points.

Term

butt weld

A butt weld is when two metal pieces are joined directly end-to-end. More joints can mean more welding work and more places where strength depends on the weld quality.

Term

CNC bend

CNC bending is a machine-controlled way to bend metal tubes very precisely. It lets you make the frame shape without as many cut-and-weld joints.

Term

torsional stiffness

Torsional stiffness is how resistant a chassis is to twisting forces. Higher torsional stiffness generally improves handling consistency because suspension and alignment geometry stay more stable when the car loads up over bumps and during cornering.

Term

sway bars

A sway bar helps keep the car from leaning too much in corners. The host is saying round shapes help the bar resist twisting forces.

Term

sprung through shock

“Sprung” just means the car’s suspension is doing the work of supporting the car. Instead of the tires taking everything, the springs and shocks share the load, especially when you corner.

Term

coil over shocks

A coil-over is basically a spring and a shock absorber working together. The spring supports the car, and the shock controls how fast the car moves up and down so it stays planted in turns.

Term

recoil

Recoil is the car’s bounce-back after it squats or compresses in a turn. If it bounces back too slowly or too much, you have to wait before you can put power down confidently.

Concept

wrap up (chassis)

“Wrap up” is how much the frame flexes when you load it in a corner. If the chassis flexes less, the car usually feels more controlled and you can get on the gas sooner.

Term

chassis twisting

When you turn hard, the car’s frame can twist like a wrench. If it twists too much, the wheels don’t stay in the best position, and the car feels less stable.

Term

rolling up into the corner

This is the car leaning as you start turning. The amount and speed of that lean changes how the tires grip and how the car feels when you turn in.

Term

G load

G load is just how hard the car is being pushed in a direction—like how strong the forces feel when you corner. More cornering G means the suspension and tires are working harder.

Concept

first set / second set (suspension settling)

The “first set” is the car’s initial bounce/settling when you load it in the turn. The “second set” is what happens after it finishes that movement—when the car is ready to hook up and accelerate.

Concept

round tube versus square tube

This is about the shape of the metal tubes in the car’s frame or cage. Different shapes can make the structure stiffer in different ways, which can help the car stay more stable in corners.

Chevrolet Camaro
Car

Chevrolet Camaro

They’re also talking about the Chevrolet Camaro. It’s a performance car with a big enthusiast following, so it’s common to hear it mentioned alongside other racing-oriented cars.

Chevrolet Corvette
Car

Chevrolet Corvette

They’re talking about the Chevrolet Corvette. It’s a sports car that many people buy because it’s built for performance and there are lots of parts and upgrades available.

dodge challengers
Car

dodge challengers

They’re mentioning the Dodge Challenger. It’s a muscle car people like for its power and style, and there are lots of upgrades available.

Term

mechanical grip

Mechanical grip is how well the tires can “grab” the road because of the car’s suspension and how it loads the tires. It’s the kind of grip you feel when the car sticks through turns even without downforce.

Term

steering rack

The steering rack is the mechanism that turns your steering wheel into the wheels turning left or right. Where it sits in the car matters because it can affect how the car behaves over bumps.

Term

uprights

Uprights are parts near the wheel that help connect the suspension to the wheel. Their position affects how the wheel moves and how the steering feels.

Term

bump steer

Bump steer is when hitting bumps makes the steering wheel turn by itself. Good suspension design keeps that from happening so the car stays predictable.

Concept

knife edge

“Knife edge” is a driving/handling concept describing a car balanced right at the limit of grip. When a car is on the knife edge, small inputs or disturbances can cause it to lose the line, so the driver and chassis must manage stability precisely.

Term

sequential transmissions

A sequential transmission means you shift up or down in order, like a step-by-step gearbox. Race cars like it because it can make shifting quicker and more consistent when you’re driving hard.

Term

FD field

“FD” is Formula Drift, a major drifting competition. Saying the “FD field” uses a certain gearbox is basically saying it’s common among drivers who really beat on their cars.

Term

CAD

CAD is a computer program for designing parts. Instead of guessing, you can test fitment virtually to make sure things clear and don’t hit when the car moves.

Term

center of gravity

Your car’s center of gravity is basically where the weight “balances.” If you lower it, the car tends to feel more stable and less likely to tip around in corners.

Term

ballast

Ballast is extra weight you add on purpose. Racers use it to meet rules or to help the car handle better by putting the weight in the right spot.

Term

14 inches of rear rubber

They’re talking about how wide the tires are. Wider tires usually grip the road better, but the car still has to be set up correctly so it doesn’t spin or slide.

Term

aero

Aero is how the car’s shape interacts with the air. The right aero setup can push the car down onto the tires for better grip and faster cornering.

Term

900 horsepower

Horsepower is how strong the engine is. More horsepower can help you go faster, but you still need enough tire grip to use it effectively.

Term

two inches off the ground

That’s how low the race car sits to the track. Sitting lower can help the car stick better, but if it’s too low it can hit the ground.

Term

600 foot pounds of torque

Torque is the engine’s pulling strength. It helps the car accelerate, but if it’s too much for the tires, the car can lose grip.

Concept

tame the monster

A race car can have so much power and grip that it feels hard to control. The goal is to drive smoothly so the tires keep traction and the car doesn’t get loose or slow you down.

Concept

driver coaching area and a car coaching area

They’re saying this series is like a training ground. Drivers learn how to handle the car better, and teams learn how to set the car up so it performs more consistently.

Concept

proven grounds

They mean this is a proving/testing place. You learn and improve in real race-like conditions before stepping up to bigger competition.

Topic

Daytona

They’re talking about Daytona as the track where they measured how fast the car is. Different tracks change how the car’s power and grip show up.

Term

NASCAR engine

They’re talking about the engine rules for NASCAR. This class allows older NASCAR-style engines, which affects how the car makes power and how teams tune it.

Concept

NASCAR Cup cars

In NASCAR, the “Cup” level is the top, most competitive series. The speaker is saying the engine tech they’re using traces back to that top-level Dodge racing program.

Company

Penske

Penske is a well-known NASCAR team. They also help with race-engine programs, so the engines mentioned here are tied to their Dodge racing history.

Term

R5

“R5” refers to a specific iteration of a NASCAR engine design used under the rules at the time. The speaker contrasts it with “R6,” implying a newer/allowed configuration within their Dodge NASCAR program.

Term

R6 Dodge design

R6 is a newer allowed version of the race engine. When rules let you use a newer version, it can change how the car performs and how teams set up the rest of the program.

Term

Sebring

Sebring refers to the Sebring International Raceway in Florida, a famous endurance/road-racing venue. The speaker uses it as a reference point for a driver’s performance, indicating the driver has succeeded in high-profile road-course competition.

Term

points

“Points” are the season-long scoring totals that determine standings in NASCAR. The speaker is using the driver’s points position (third or possibly fourth) to gauge how competitive the program is.

Term

Atlanta race

“Atlanta race” refers to a NASCAR event at Atlanta Motor Speedway, used here as a benchmark for the driver’s points position. Points standings after specific races are a common way teams measure progress.

Concept

driver development program

A driver development program is like a training pipeline for racing talent. Instead of just putting someone in a car, you coach them and give them chances to improve step by step.

Term

road course

A road course is a type of race track with lots of corners, not just left turns on an oval. It usually demands different driving skills, so coaches focus on that style.

Term

saves his tires

“Saving tires” means managing tire wear so the car remains fast later in the race. The speaker credits Boris’s methodical approach—preserving tire grip early to have performance at the end—leading to frequent podiums.

Topic

Emsa GT type racing

This is about a different kind of racing where “GT” cars compete. The speaker is saying some drivers are coming from that background into Trans-Am.

Topic

Trans-Am

Trans-Am is a road-racing series where cars compete under a specific rule set and class structure. The speaker discusses rebuilding the class and growing participation toward a target “car field” size, highlighting how entry counts affect the health of the series.

Concept

car field count

Field count is just how many cars actually show up to race. More cars usually means more competition and a better event overall.

Concept

race smart

Race smart means you don’t just spend money—you make good decisions. With less budget, you focus on the choices that give the biggest payoff.

Concept

build our stuff. We don't buy it.

They’re saying they make their own racing parts instead of buying ready-made ones. That can save money and also let them tailor the car to how they race.

Topic

Baja 1000

The Baja 1000 is one of the most famous off-road desert races in North America, known for long-distance endurance and rough terrain. Mentioning it (along with other Baja events) frames the speaker’s background as endurance-focused off-road racing rather than circuit-only competition.

Topic

Baja 500

The Baja 500 is another big off-road desert race. Like the Baja 1000, it’s about endurance and handling rough terrain.

Concept

Lake Norman

Lake Norman is a big lake near Charlotte, North Carolina. The guest is describing how living there makes it easy to go boating and enjoy the outdoors.

Concept

shop (attached garage/workshop)

They’re talking about a workshop space on the property. For car people, a shop is where you can work on vehicles, store tools, and do projects.

Concept

Barnum Minions

It sounds like a local group or shop nickname. The point is that in racing communities, there are often dedicated crews that help people build and maintain cars.

Concept

TIG welder

A TIG welder is a tool for welding metal very precisely. It’s popular in racing because it makes strong, clean welds for custom parts.

Topic

Formula 1, Formula 5,000, Indy car, midgets, dirt champ cars, drag racing, funny car, and top fuel

The guest lists a wide range of racing categories (open-wheel, dirt, and drag) to illustrate how broad the Parnelli operation was. For listeners, it highlights how skills and engineering approaches can transfer across very different types of racing.

trophy trucks
Car

trophy trucks

Trophy trucks are race trucks built for desert off-road events. They’re made to survive big bumps and jumps while staying fast.

Concept

co-pilot

In off-road desert racing, a co-pilot (or navigator) helps manage pace, route information, and strategy—especially in events where navigation and timing matter as much as driving skill. The role can be critical for avoiding wrong turns and maintaining consistent performance over long distances.

Concept

single-seater

A single-seater is a race car made for just one driver. Building one yourself is a common way racers learn how cars are built and how to make them work.

Topic

Mickey Thompson Stadium series

The Mickey Thompson Stadium series refers to off-road racing events held in stadium-style venues, bringing desert-style vehicles to a more spectator-friendly format. These series helped popularize off-road racing by making it easier to watch and follow.

Topic

1977 Off-Road World Championship Grand Prix

This is a specific off-road race from 1977. The host is basically saying you can look up the footage to see what racing was like back then.

Term

fabrication process

They’re talking about fabrication—how parts get built and put together. The key idea is there isn’t only one “right” way, as long as it works well and looks decent.

Term

no lift shift

No lift shift means you don’t back off the gas when you shift. The car keeps making power through the gear change, so it accelerates harder.

Company

Enthmodo

Enthmodo is mentioned as the group that does the transmission work behind the “6XD” experience. They’re basically associated with the racing tech that lets you shift without lifting off the gas.

Term

reverse lockout

A reverse lockout is a safety/control feature that stops you from accidentally putting the car into reverse. It helps protect the transmission from being shifted into the wrong gear at the wrong time.

Term

four-speed NASCAR transmission

This is a racing-style 4-speed transmission NASCAR used for a while. It’s chosen because it’s cheaper and fits the race car’s layout, not because it’s meant for everyday driving.

Term

dog ring transmission

A dog-ring transmission is a race gearbox that shifts gears with metal “clutches” that lock into place quickly. It doesn’t use the smooth synchronizers you’d find in most street cars.

Term

Gen 7

“Gen 7” refers to NASCAR’s next-generation vehicle/competition rules package that changed how cars are built and what components are used. When he says the dog-ring four-speed was used before Gen 7, he’s pointing to a rules-driven shift in transmission technology.

Concept

turn it on its side, rotate it 90 degrees

Instead of mounting the transmission the usual way, he rotated it so it fits better in the car. That can help with space and handling, but you have to redesign the oiling and shifting so it still works reliably.

Term

oil system

If you rotate a transmission, the oil doesn’t naturally sit where it used to. The oil system has to be redesigned so the gears and bearings still get enough lubrication.

Term

crank centerline

This is a measurement reference point on the engine. He’s using it to explain how close the bottom of the car is to the ground so the car can be low without scraping.

Term

fifth gear

With only four gears, the engine may not stay in the best RPM range as often. Adding a fifth gear can help the car accelerate and maintain speed more effectively.

Term

sequentials

Sequential transmissions let the driver shift through gears in order (typically one gear at a time) rather than using an H-pattern. In racing, sequentials are valued for fast, consistent shifts under load.

Concept

layover style

He’s describing a transmission mounting orientation (“layover”) that mirrors the earlier rotated four-speed approach. The goal is better packaging and clearance while keeping the gearbox’s lubrication and shifting behavior correct.

Term

guinea pig

He uses “guinea pig” to describe being the first to try a new setup or prototype. In racing engineering, early testing carries risk—things may break or need refinement before they become reliable.

Company

Haltech

Haltech makes aftermarket computers for cars (ECUs). They help your engine computer work with other car systems, so you can run a more modern setup without fighting compatibility issues.

Term

transmission interfaces

When you swap in an aftermarket engine computer, it may not “talk” to the transmission the same way the factory computer did. A transmission interface is the translator that helps everything work together.

Term

4L and 6L series transmissions

This is shorthand for certain GM transmission models. The important takeaway is that the aftermarket interface being discussed is made to work with those specific transmission families.

Term

standalone ECU

An ECU is the car’s engine computer. A standalone ECU is an aftermarket one that gives you more control over tuning, but it usually needs extra wiring/parts so it can work with the rest of the car.

Concept

plug and play solutions

Plug-and-play means the parts are made to install with less cutting, splicing, or custom wiring. It’s meant to be easier and more reliable than a complicated DIY wiring job.

Concept

road racing instead of off road racing

Road racing is usually smoother and more about staying planted and controlled on pavement. Off-road racing hits lots of bumps and rough terrain, which is tougher on both the driver and the car.

Concept

off road program

An off-road program is basically the whole racing operation behind the scenes—building the truck, keeping it running, and having people dedicated to the team. It’s more than just showing up to races.

Topic

King of the Hammers

King of the Hammers is a super tough off-road race. Cars and trucks have to survive rough desert terrain, so failures are common and preparation matters a lot.

Topic

Mint 400

The Mint 400 is a big off-road race near Las Vegas. Even if a team is doing great, one mechanical problem can ruin the whole result.

Term

drive shaft failure

A drive shaft is the part that sends power from the gearbox to the wheels. If it fails, the car can lose drive or stop completely, which is especially bad during a race.

Trans Am
Car

Trans Am

Trans Am is a racing series. The cars are built specifically for competition, and here they’re talking about developing their race car over several generations.

Concept

Gen one

“Gen one” means the first version of their race car design. They started with an initial build, then refined it later to make it stronger and faster.

Concept

Gen two

“Gen two” is the next improved version of their race car. They kept the same general tube-style frame, but made it stiffer by changing how the frame pieces were arranged.

Term

square tube construction

Square-tube construction means the frame is made from square metal tubes. The way those tubes are connected can make the car feel more solid and predictable when it’s being pushed hard.

Term

stiffer

“Stiffer” means the frame flexes less. When the car flexes less, the tires can keep better contact with the road and the handling feels more consistent.

Concept

Gen three

“Gen three” is the next big redesign. Instead of just tweaking the old frame, they changed the design more radically to improve how the car performs.

Topic

NASCAR stint

A “stint” just means a stretch of time doing something. They’re saying their NASCAR time happened at a different point than when they were building the Trans Am cars.

Company

Earnhearts

“Earnhearts” likely refers to the Earnhardt racing family. In NASCAR, that name is associated with major teams and a lot of racing know-how.

Term

waivers

“Waivers” here sounds like exceptions or approvals that let teams keep racing or use certain parts. It’s part of how teams recover after crashes and get back on track.

Concept

35 car field

A “35 car field” just means there were about 35 cars competing. They’re using that number to show how many teams relied on their parts and support.

Concept

build all those parts that got wrecked and smashed and broken

Racing breaks cars. This is describing how they’d go to races, then rebuild or replace the damaged parts so teams could keep competing.

Company

DEI

DEI is short for Dale Earnhardt Inc., a big NASCAR racing organization. The host is basically saying their shop was like a dream workplace for race preparation—very high-end and well resourced.

Topic

Earnhardt's group through a mutual friend

They’re talking about how the speaker got connected to a major NASCAR team through someone they both knew. That connection led to work inside a high-level racing shop.

Term

subcontractor

A subcontractor is someone hired to do a particular job for another company. The speaker is saying they started by helping out with specific work before becoming more involved.

Term

bodywork

Bodywork is the process of shaping, fitting, and mounting the car’s outer panels. In racing, getting it aligned correctly helps the car look right and behave consistently at speed.

Concept

reference table with a groove centerline

They use a big, super-accurate measuring platform with a line cut into it. That line helps them line up the chassis correctly so the frame isn’t crooked.

Concept

frame rail

Frame rails are the main “beams” of the car’s frame. If you measure them carefully, you can tell whether the chassis is built straight and square, which matters a lot for handling.

Concept

ground clearance (mimicking ground clearance for the chassis)

They lift the chassis off the table so it sits like it would on the ground. That way, the measurements match the car’s real ride height instead of being taken in a “flat” position.

Term

4 inch by 3 inch tube

That measurement is the size of the metal tube used in the chassis. Bigger or stiffer tube sections help the frame resist flexing when the car is cornering or hitting bumps.

Term

eighth wall

“Eighth wall” refers to tube wall thickness—here, an eighth of an inch. Wall thickness is a key factor in chassis stiffness and strength, and it also influences weight.

Term

zero (measuring from the outside of that tube)

“Zero” is their starting point for measuring. Instead of guessing, they pick one fixed spot on the chassis and measure everything else from there.

Concept

centerline alignment

Race cars need to be built so the frame is lined up correctly. If a metal tube is slightly bent from welding, the car can “aim” a little off without anyone noticing, and that can hurt how it drives at speed.

Term

thick-wall rectangular tubing (four inches by three inches)

They’re talking about the size of the metal frame tube they used. Even with heavy-duty tubing, welding can still bend it slightly, and that can mess up the car’s alignment.

Concept

weld-induced tube arching (heat distortion)

When you weld metal, the heat can make it warp. Even if the tube starts straight, the weld can pull it into a curve, which then throws off the car’s alignment.

Term

straight edge

A straightedge is a precision reference tool used to detect bends or high spots in a fabricated tube. In this context, it’s used to verify whether the welded tube is actually straight relative to the intended alignment.

Concept

yaw (chassis misalignment)

Yaw is basically a sideways “aim” error—like the car is pointed a little off from where it’s actually going. If the frame is twisted or rotated slightly, the tires and body don’t work together the way they should.

Concept

body-on-skeleton chassis inconsistency

Even if the frame is close, the way the body gets bolted on can change how the whole car lines up. Small differences in mounting can lead to big differences in how the car behaves on track.

Concept

projecting a line

It’s a way to create a straight reference so you can tell if something is centered or bent. If the reference line doesn’t match the car’s real center, you can measure the error and fix it.

Concept

squaring up their four tires

It means making sure the car’s wheels are positioned evenly and the car isn’t crooked. When the measurements are off, the car can pull or handle inconsistently, so teams fix it by measuring and adjusting.

Concept

centerlines in the chassis

They mark the car’s true center so everything else can be aligned to it. If the body isn’t centered the same way every time, the race car can behave differently from one build to the next.

Concept

string bar program

They set up strings as straight guides, then measure how far each wheel is from those guides. If one side is different, the car won’t handle the same way corner to corner, so the strings help them correct it.

Concept

rear end's not leading on one side

“Rear end leading” describes a situation where the rear axle or rear structure is offset so one side effectively reaches the reference line first. Teams use measurement to ensure the rear is centered and not skewed, which affects straight-line tracking and corner balance.

Brand

Dale Earnhardt

This is a famous NASCAR driver’s name. The speaker is saying their measurement process ended up being useful for a team connected to Earnhardt.

Company

Ronnie Hopkins

They’re talking about a company that makes race-car chassis parts. If you buy from a supplier, you start with their design instead of building everything from scratch.

Company

Hendrick

They’re talking about Hendrick as another major team starting to build their own chassis. That can help them test changes faster and tailor the car to their drivers and setups.

Term

suspension things

This is about tuning the suspension so the tires stay planted and the car handles the way you want. Even small changes can make a big difference on track.

Term

tube placement

The chassis has a framework made of tubes. Where those tubes are placed affects how the car flexes, which changes how it feels and handles.

Concept

NASCAR rule packages and how they changed over time

Racing rules change what teams are allowed to do. When the rules change, teams often have to redesign parts and focus on different performance areas.

Concept

composite body panels vs all-steel sheet metal

Back then, race bodies were mostly steel and shaped using templates. Now many parts are made from composite material and come out of a mold, then you bolt them on—so the process is more standardized.

Term

diffuser

A diffuser is a shape under the race car that helps control air as it flows underneath. Better diffuser design can push the car down harder for more grip in corners.

Concept

prototypes for NASCAR

A prototype is an early test version. NASCAR teams build prototypes to make sure the design works and the parts fit together before they commit to building many cars.

Concept

NASCAR chassis

In racing, the chassis is basically the car’s skeleton. It’s what everything else bolts to—so it strongly affects how the car drives and how safely it’s built.

Company

Techniques

Techniques is described as a Michigan-based fabrication company that uses computer-controlled robotic tube bending and tube cutting, plus laser cutting of chassis components. The key point is that they provide a repeatable, CAD-driven kit process for building race car structures.

Concept

fish mouthing

When two tubes meet, you can cut the end of one tube so it matches the other tube’s shape. That makes the joint fit better and weld more cleanly.

Part

laser cut chassis components

Laser cutting is like using a super-precise machine to cut metal shapes. When it’s used for race-car parts, it helps the pieces fit together the way they’re supposed to, with less guesswork.

Concept

COT (car of tomorrow)

The COT, or “Car of Tomorrow,” was NASCAR’s next-generation race car platform introduced to standardize design and improve racing consistency. The speaker connects their chassis shop work to the start of building this new chassis generation.

Brand

Dodge sponsorship

When a race team is sponsored by a manufacturer like Dodge, it often determines what kind of engines they run. If the sponsorship changes, the whole engine setup can change too.

Concept

dynoing and tuning

The segment explains that Penske’s engine program involved developing engines, dynoing them, and tuning them. A dyno lets teams measure power and refine settings (like ignition timing and fuel delivery) before the engine ever sees race conditions.

Brand

Ford's

They switched from Dodge to Ford. That kind of switch usually means the team changes which engines they use and how they get them.

Company

Roush Yates

Roush Yates is mentioned as the source of Penske’s Ford engines via a leasing program. In top-level racing, teams may lease race engines from specialized builders to ensure consistent performance and support.

Concept

lease program

The “lease program” describes how race teams obtain engines from an outside supplier rather than building and maintaining their own engine shop. This can change staffing, processes, and how tuning responsibilities are handled.

Term

head work

“Head work” refers to modifications and preparation of the engine cylinder head, typically including porting, valve work, and surface/fitment corrections. In racing, cylinder head work is a major factor in airflow and combustion efficiency, which affects power.

Term

block work

“Block work” is engine-building work performed on the engine block, such as machining, fitting, and preparing the foundation for the rotating assembly. In racing programs, block work is critical for durability and for achieving the desired internal engine geometry.

Term

dyno work

“Dyno work” refers to testing engines on a dynamometer to evaluate power and tune settings. The transcript credits Danny Glad with dyno work, emphasizing how dyno results guide calibration decisions for race engines.

Concept

race weekend

A race weekend is everything you do around the event. It usually starts with travel and setting up, then you do practice/qualifying runs before the actual race.

Term

Grand Canyon

They mention the Grand Canyon to show how racing schedules are so packed that you don’t really stop for sightseeing. You’re focused on getting to the track and racing.

Topic

Formula One track

They mention it’s a Formula One track to give context about the venue. It signals that the track is big and professional, so the event schedule is more structured.

Concept

qualifying vs race day sessions

Qualifying is about getting a good starting spot, and the race is about finishing the event. Teams use practice sessions to make sure the car is working well before the race.

Concept

driver acclimated to the whole day

The first on-track run is often used to get the driver comfortable with track conditions, tire behavior, and the car’s baseline setup before making targeted changes. This “warm-up” approach reduces the chance of chasing problems that are really just driver adaptation.

Term

ride height

Ride height is how high the car sits. Changing it can change how the car grips the road and how it behaves in corners.

Concept

overlay

“Overlay” is a data-analysis method where video and sensor data are synchronized so the team can compare what the driver did (steering/throttle/braking) with what the car did (speed, line, and corrections). It helps translate driver feedback into measurable cause-and-effect for setup changes.

Term

throttle position

Throttle position tells you how much gas the driver is using. Teams look at it to understand how the car is accelerating and whether the driver is getting the traction they need.

Term

steering input

Steering input is basically how much the driver turns the wheel. Recording it helps the team understand the driver’s actions during the lap.

Term

brake pressure

Brake pressure refers to how much hydraulic force is being applied at the brakes, often tracked separately for front and rear. In racing, analyzing brake pressure helps diagnose balance issues like locking, under-braking, or instability under decel.

Concept

balance all that out

Changing the car for one corner can make it worse somewhere else. Teams adjust things so the car works well overall, because the lap is a whole package.

Term

corner speed

Corner speed is how fast you go while you’re turning. If you can carry more speed through the corner, you often end up faster for the whole lap.

Concept

amount is a weight is a placement

It’s saying that not only how heavy the car is matters, but also where that weight sits. Where the weight is placed can change how the car turns and how stable it feels.

Term

spare engine

A spare engine is a backup engine ready to install if the current one breaks. It helps the team get back on track faster, but it costs a lot to maintain.

Topic

Sonoma double header

A double header is two races at the same track in one weekend. They do it to help teams save money and reduce travel.

Concept

budgeting per race (local mileage vs West Coast travel)

They’re explaining how teams estimate what each race will cost. Races farther away usually cost more because of extra travel time and fuel.

Concept

amortizing expenses across multiple races

The speaker describes spreading costs over multiple events—e.g., an engine isn’t only used for one race. Instead, teams plan rebuild intervals and part replacement so the expense is “amortized” across the season rather than paid all at once.

Term

engine expense

They’re talking about the money spent to keep the race engine running. In racing, engines wear out and need rebuilds, so teams budget for that repeatedly.

Part

valve springs

Valve springs are small parts inside the engine that help the valves move correctly. Race teams often replace them on a schedule because hard driving can make them wear out faster.

Concept

engine refresh cycle (miles between rebuilds)

They’re talking about a schedule for when to service the engine. Instead of waiting for something to break, they run it for a while, check it, refresh key parts, and then keep racing.

Term

check clearances

Clearances are the tiny spaces inside the engine between parts. If those gaps aren’t right, the engine can run poorly or even get damaged, so teams measure them after a certain mileage or run time.

Term

shot rods out the pan

That phrase means the engine broke in a really dramatic way. A rod failed and ended up tearing through the bottom of the engine, usually destroying the engine and requiring a rebuild.

Term

mag checks

A “mag check” is a quick way to look for metal bits that shouldn’t be there. If the gearbox is shedding metal, it’s a warning sign that something is wearing out.

Concept

land speed project

This is a project where a team tries to set a top speed record on land. Instead of a normal racetrack, they use a special course designed to be very fast and predictable.

Concept

500 barrier

They’re talking about the big milestone of getting to 500 mph. At that speed, the car has to be extremely stable and efficient, and even small problems can stop the run.

Concept

wheel driven piston powered vehicle

This means the engine is a piston engine and it turns the wheels to move the car forward. That’s different from rockets or jets, which push forward using thrust.

Concept

thrust versus traction

Thrust is like pushing the vehicle forward with force from an engine’s exhaust. Traction is how well the tires grip the ground—if grip isn’t enough, the wheels can spin instead of accelerating.

Term

Viper V10s

They’re using two V10 engines—each one has ten cylinders arranged in a V shape. Using two engines is a way to make a huge amount of power for a record attempt.

Concept

top fuel car

Top Fuel is a drag racing class with super-powerful cars. The point here is that the owner has experience handling big power and keeping the car under control.

Concept

Bonneville, Utah

Bonneville, Utah is the famous location for land-speed racing on the Bonneville Salt Flats. The salt surface provides a hard, relatively low-friction track that helps vehicles achieve very high speeds, but it still requires careful planning for weather, surface condition, and safety.

Term

compressed air on board

They’re using stored air pressure in the car to help change gears. When you press a button, that air helps move the shift parts for you.

Term

two transmissions

They’re talking about a car that has two gearboxes. The tricky part is making sure both gearboxes shift together so the car doesn’t fight itself.

Term

air charge

An “air charge” is a quick push of pressurized air. It’s what actually makes the shifting happen when you hit the button.

Term

selenoid

A solenoid is like an electrically controlled valve. It decides when pressurized air gets sent to the mechanism that moves the shifter.

Concept

cancel the torque of the engine

They’re trying to reduce the twisting force from the engines. By arranging the engines so their forces oppose each other, the car should track straighter with less driver correction.

Concept

keep it on that black line on the salt

They’re talking about staying perfectly straight during very fast runs. The “black line” is a target to follow, and the car’s design is meant to reduce how much you have to steer to stay on it.

Term

differentials

A differential is what lets wheels turn at different speeds when you’re cornering. That matters because the inside and outside wheels don’t travel the same distance.

Concept

four-wheel drive

Four-wheel drive means the car can push with all four wheels instead of just two. That usually helps when the road is slippery or when you’re trying to put down a lot of power.

Term

MoTeX electronic system

This sounds like an electronic control system that helps coordinate multiple engine and drivetrain components. Instead of each system acting on its own, the computer helps them work together.

Concept

Sensors are the car’s “eyes and ears.” If you have a lot of them, the computer can make smarter decisions—but it also means the build is more complicated.

Nissan Juke
Car

Nissan Juke

The Nissan Juke is a small crossover, meaning it’s built to be easy to drive like a regular car but with a higher seating position. It’s known for having a unique, eye-catching design. The podcast mention sounds like it’s using the name “Juke” as a wordplay reference.

Concept

electronic setup and testing

With a complicated car, you can’t just bolt everything together—you have to program and fine-tune how it all works. Then you test it to make sure it behaves correctly when you drive hard.

Term

time travel

They’re joking that the project timeline feels impossible to predict. Big builds like this often take longer than expected because everything has to be tested and made to work together.

Company

SureThing Logistics

SureThing Logistics is referenced as a company the speaker will own, tying into the practical side of transporting cars to events. For racing builds, reliable logistics can be as important as the mechanical work.

Brand

Term

AVCS cam gears

AVCS cam gears refer to the camshaft timing components used on Subaru engines with AVCS (Active Valve Control System). Rebuilding AVCS cam gears can restore proper valve timing without purchasing brand-new parts, which can be expensive.

Part

bushings

Bushings are small parts that help connect components while absorbing movement and vibration. Upgrading them can make the car feel tighter, but it may also make the ride a bit harsher.

Part

short shifters

A short shifter is a drivetrain modification that reduces the lever travel between gears. That typically makes shifting feel quicker and more precise, especially in cars where the factory shifter action feels long.

Company

CarPoi

CarPoi is an aftermarket parts company. In this segment, it’s mentioned because it makes parts that improve shifting and handling on Subaru cars.

Concept

three wheel drive

“Three wheel drive” means the vehicle sends power to three wheels. Instead of just two wheels getting driven, three wheels help with traction.

Concept

slingshots

The speaker compares their concept to “slingshots,” referring to a category of three-wheeled vehicles that became popular in the early 2000s. The key point is that they view many of those designs as more style/novelty than performance-focused.

Concept

t-rex

They mention “T-rex” as another example of a three-wheeled vehicle from that era. They’re using it to say those kinds of cars didn’t really focus on performance.

Concept

street legal

“Street legal” means it’s meant to be allowed on public roads. That usually requires meeting rules for safety and equipment, not just being fast.

Concept

mass produce these chassis

They’re describing making the chassis in large numbers instead of one-off custom work. The goal is to make it easier for regular people to buy and build.

Part

laser coped

This sounds like using a laser to cut metal parts precisely. The benefit is that the pieces fit together better and are easier to repeat for many builds.

Concept

powder coated

Powder coating is a surface-finishing process where a dry powder is applied and then baked to form a durable protective layer. On a chassis, it helps resist corrosion and wear, which matters for longevity—especially if the vehicle will be street-driven.

Concept

three phase

They’re talking about building the vehicle in steps (“phases”). You start with a smaller package, then you can decide later whether to buy the next parts and keep going.

Concept

two car garage

They’re saying the build is meant to be doable at home, in a normal garage. That usually means the parts are designed to be assembled without a full machine shop.

Concept

kit

A “kit” is a package of parts you assemble yourself. Instead of buying a finished vehicle, you buy components and put them together.

Concept

phase one, two or three

They’re talking about building the car in steps. You start with a basic setup, then upgrade it later as you want more performance or features.

Concept

air cooled, no radiator

Air cooling means the engine gets cooled by air instead of coolant flowing through a radiator. It can be simpler, but you have to make sure the airflow is right so the engine doesn’t overheat.

Term

roll cages and roll bars

A roll cage is a full structural framework of tubes designed to protect occupants during rollovers and impacts, while roll bars are partial versions. In track-oriented builds, these structures are often integrated with safety harness mounting points and reinforced mounting to maintain rigidity.

Concept

electric rear wheel drive

They’re describing a setup where an electric motor powers the back wheels. The goal is to drive efficiently (and possibly recharge on the way back) while still having fun.

Concept

turbocharged

Turbocharging is a way to make an engine produce more power. It forces extra air into the engine so it can burn more fuel and make more horsepower.

Term

brimbo brakes

Brembo is a brand that makes performance brakes. Better brakes help you stop harder and keep working even when you’re driving aggressively.

Springs help support the car and control how it reacts when you brake, turn, or hit bumps. Performance springs can make handling more predictable.

Term

Briggs lawnmower engine

They’re talking about a small, simple engine—like the kind you’d find in a lawnmower. Those engines are usually not very powerful, so the project is about making the whole setup more capable.

Concept

one wheel drive

“One wheel drive” here means a single-driven wheel setup (commonly front- or rear-wheel drive depending on the vehicle layout). With only one axle driving, torque can be harder to manage because the driven tire is more likely to spin, making traction control and tire choice especially important.

Concept

four different braking program

They’re talking about different ways the car can brake depending on the mode you choose. That can change how quickly it slows down and how stable it feels when you’re pushing it.

Concept

trike (three-wheeler) motorcycle license

They’re talking about how a three-wheeled vehicle might be treated like a motorcycle for licensing. That can change what paperwork and license you need compared with a normal car.

Concept

three-wheeler racing platform

They want to race a three-wheeled vehicle like a real motorsport. Because it’s not a normal car, it would likely need special rules and a different kind of setup to be safe and competitive.

Term

hydraulic disconnect in the rear wheel

This sounds like a system that can temporarily “separate” what the rear wheel is doing, using fluid pressure. The goal would be to help the vehicle grip better or behave more predictably when turning.

Term

turning brake

They’re describing a brake strategy used while turning. By locking one wheel, the car can be made to pivot or rotate more, but it’s tricky because it depends heavily on tire grip.

Term

rear brake only

They’re talking about a setup where braking is only applied at the back. That can change how the vehicle behaves when you slow down, which matters a lot for traction and control.

Term

regular clutch

They mention a normal clutch, like you’d find in a manual transmission. In a custom build, the clutch still matters because it controls how power gets to the drivetrain.

Term

parking brake

They’re describing a brake that works like a parking brake, but it’s been adapted for this vehicle. Instead of just holding the car still, it deploys something to touch the ground and create braking/holding force.

Concept

balancing point of the car front to rear weight

They want the braking force to act near where the car’s weight is balanced front-to-back. That helps the vehicle stay stable instead of tipping or twisting when the brake engages.

Term

dump the clutch

Dumping the clutch means letting the clutch out really fast to get the car moving quickly. It can make the launch violent, so it can stress parts like the transmission and driveshaft.

Concept

spin on its own axis

They’re describing a maneuver where the car rotates in place instead of just driving forward. It happens when the tires lose grip and the driver uses throttle and braking to keep it spinning.

Concept

rally is so intense and... destroy the Gearbox

Rally driving is rougher and more chaotic than normal street driving. The drivetrain gets hit with lots of sudden forces, so transmissions often need upgrades to last.

Term

aftermarket... tuning side of things

They’re talking about using an aftermarket computer/tuning setup instead of the factory one. That lets you adjust how the engine runs so it performs better with the modifications.

Term

stock ECU

The ECU is the car’s computer that controls things like fuel and ignition. A stock ECU uses the factory settings, which might not be ideal for a modified engine.

He’s talking about a V6 engine that’s 4.5 liters. The idea was to base it on a known engine design and modify it to fit the rules and performance goals.

Concept

power to weight recipe

He’s saying the car was faster because it had a good balance of power and weight. Less weight can make the same (or even less) power feel much quicker.

Car

off-road doom buggy

This is a custom off-road buggy built to take a beating. It’s designed for rough rides and hard use, not normal street driving.

Term

airbag

He means the suspension uses air instead of traditional springs. That can make the ride softer and help the vehicle stay controlled over rough ground.

Part

Mendiola gearbox

This is a stronger-than-stock transmission/gearbox brand. He’s using it because the buggy’s drivetrain gets hammered and needs to last.

Company

drive shaft shop out in Salisbury

They used a local shop in Salisbury that works on drive parts like axles. That matters because race/off-road vehicles put a lot of stress on those components.

Concept

off-road durability weaknesses

When you drive off-road hard, certain parts get stressed more than others and break first. Builders learn from failures and strengthen the weak spots so the car can handle the abuse better.

Term

paddle tires

Paddle tires are special off-road tires for sand. Their tread is shaped to grab and push through loose sand instead of getting stuck.

Term

wet sump

Wet sump means the engine oil sits in a pan under the engine and gets pumped around. It’s simpler than dry sump, which uses extra tanks to keep oil from starving during hard cornering or rough use.

Topic
