On this episode of the Power Driven Podcast, Todd, Will, and Myer break down what it took to get there and why the technology available to diesel builders right now is changing what is possible at every level of the sport.The guys dig into what that number actually means in context, where the money goes in a build like this, and why high level diesel performance is more attainable today than it has ever been. The conversation covers everything from drivetrain decisions to turbo costs to cylinder head development, all through the lens of what it took to put a tow truck in the fours.Pro Street diesel is growing fast and the boys make a strong case that now is the time to get in. Multiple trucks are running deep fives and dipping into the fours, the parts are better, and the price to compete has come way down compared to even a few years ago.Everything the guys talk about in this episode is available at PowerDriven.com.

In drag racing, that time is a key benchmark for how fast the vehicle accelerates under race conditions.","simplifiedExplanation":"That “4.99” is how many seconds it took to run the eighth-mile (about 660 feet). Faster time means quicker acceleration and usually more power."}},{"startTime":61.3,"endTime":77.0,"type":"concept","title":"data log","url":"/glossary/data-log","quote":"I mean, honestly is I checked the data log and I really only floored it for like 5.1 seconds. So right after the eighth mile...","canonicalId":"concept:data-log","priority":0.5,"confidence":0.9,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"A data log records sensor data during a run (like throttle position, boost/EGT, transmission behavior, and shift timing). Checking it helps the tuner confirm what the vehicle actually did versus what was expected.","simplifiedExplanation":"A data log is like a recorded report of what the truck’s systems were doing during the run. It helps them see exactly how the tune and shifts behaved."}},{"startTime":141.9,"endTime":164.6,"type":"concept","title":"Hail Mary passes","url":"/glossary/hail-mary-passes","quote":"...you're burning him up every past. Yeah, you're doing a Hail Mary passes like I remember that with, I mean, it's just even you guys and Josh and everything like five years ago we were going down the track and just hoping that the transmission would survive the drag race.","canonicalId":"concept:hail-mary-passes","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Hail Mary passes” describes runs made with little expectation of mechanical survival—essentially gambling that the drivetrain won’t fail before the end of the pass. It’s used here to describe earlier transmission setups that were prone to failing under repeated passes.","simplifiedExplanation":"That phrase means they were basically taking a chance and hoping the truck would make it through the run without breaking. It implies the car wasn’t fully reliable yet."}},{"startTime":428.0,"endTime":443.8,"type":"term","title":"torque converter lockup clutch","url":"/glossary/torque-converter-lockup-clutch","quote":"I would say the first problem I'll just throw out there is the torque converter lockup clutch drags when you're building boost at the starting line.","canonicalId":"term:torque-converter-lockup-clutch","priority":0.5,"confidence":0.9,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"The torque converter lockup clutch is a mechanism that locks the converter to reduce slip and improve efficiency. At the drag strip, if the lockup clutch drags while building boost, it can create heat and debris that damage the transmission.","simplifiedExplanation":"The lockup clutch is part of the torque converter system that helps the transmission transfer power more directly. If it starts dragging during a launch, it can overheat and wear out fast."}},{"startTime":709.2,"endTime":806.08,"type":"term","title":"band","url":"/glossary/band","quote":"Yeah.

Because it relies on friction, it can generate significant heat if it must slip during engagement and disengagement.","simplifiedExplanation":"A “band” is like a friction strap inside the transmission. When it grabs, it holds a gear; when it releases, it has to let go smoothly—otherwise it slips and makes heat."}},{"startTime":1081.5,"endTime":1084.6,"type":"concept","title":"it finally hooked everything","url":"/glossary/it-finally-hooked-everything","quote":"Oh, that's cause it finally, it finally hooked everything.","canonicalId":"concept:it-finally-hooked-everything","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Hooked everything” means the drivetrain finally achieved enough traction and torque transfer for the engine to load the turbo and make the expected power. In practice, this often happens when the tires stop spinning and the transmission/torque converter behavior matches the traction available.","simplifiedExplanation":"They mean the truck finally got good traction and started transferring power to the ground. Once it hooks up, the turbo can build boost the way it’s supposed to."}},{"startTime":1106.0,"endTime":1111.4,"type":"term","title":"six 20","url":"/glossary/six-20","quote":"...you used to see, but you're like, man, I ran a six 20, but look at that mile an hour though.","canonicalId":"term:six-20","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Six 20” is shorthand for a 6.20-second elapsed time (ET) in drag racing. ET is a primary measure of acceleration and overall run performance, influenced by traction, gearing, and drivetrain efficiency.","simplifiedExplanation":"“Six 20” is a quick way of saying the car ran about 6.20 seconds. That’s how long it took to cover the race distance from the start."}},{"startTime":1171.0,"endTime":1175.2,"type":"term","title":"overdrive gear","url":"/glossary/overdrive-gear","quote":"[1166.8s]  And a lot of diesel racing is traditionally eighth mile now, but if you ever want to do\n[1171.0s]  a drag and drive event that's quarter mile, you can't run that in a turbo 400.\n[1175.2s]  You need an overdrive gear and they don't have that.","canonicalId":"term:overdrive-gear","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"An “overdrive gear” is a higher gear ratio that reduces engine RPM for a given speed. In drag-and-drive or longer-distance runs, overdrive can help keep the engine from running too fast while still maintaining acceleration.","simplifiedExplanation":"An “overdrive gear” is a gear that lets the car go faster without the engine screaming at high RPM. That can help for longer runs where you don’t want the engine to run out of steam or get too loud/hot."}},{"startTime":1177.3,"endTime":1177.3,"type":"term","title":"RPM","url":"/glossary/rpm","quote":"You don't have the RPM on the diesel. And so it's like, if you want to run quarter mile, you kind of need an overdrive.","canonicalId":"term:rpm","priority":0.9,"confidence":0.95,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"RPM (revolutions per minute) is how fast the engine is spinning. In diesel drag racing, RPM limits and gear limits matter because you may not have enough engine speed to keep accelerating through the quarter mile.","simplifiedExplanation":"RPM tells you how fast the engine is spinning. If the engine can’t spin fast enough, it can’t keep making power as you accelerate, especially in a race like the quarter mile."}},{"startTime":1196.0,"endTime":1196.0,"type":"term","title":"gear ratios","url":"/glossary/gear-ratios","quote":"Like a billet transfer case that you can put different gear ratios in. Which is cool.","canonicalId":"term:gear-ratios","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"Gear ratios determine how many times the driveshaft turns for each engine rotation. Changing gear ratios changes both acceleration and top-end speed, which is why it’s central to quarter-mile setups.","simplifiedExplanation":"Gear ratios are the “multipliers” between the engine and the wheels. Different ratios can make the truck accelerate harder or reach higher speed before the run ends."}},{"startTime":1232.0,"endTime":1232.0,"type":"term","title":"two, two 41 DLD transfer case","quote":"That's got a freaking two, two 41 DLD transfer case is why not?

So it doesn't have a planetary in there or anything now.","canonicalId":"term:four-low","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“4 Low” (four-wheel drive low range) uses a lower gear ratio for maximum torque at low speeds. The speaker says they removed it, which changes how the transfer case provides gearing and internal components.","simplifiedExplanation":"4 Low is the “low gear” mode for 4WD that gives more pulling power at slow speeds. Removing it means the transfer case no longer has that low-range function."}},{"startTime":1293.1,"endTime":1294.9,"type":"part","title":"planetary","quote":"So it doesn't have a planetary in there or anything now. So it's just kind of straight through...","canonicalId":"part:planetary","priority":0.2,"confidence":0.65,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"A planetary gearset is a compact gear arrangement used in many transfer cases to create different gear ratios, including low range. Removing the planetary gearset can simplify the unit and reduce weight, but it also removes low-range functionality."}},{"startTime":1300.2,"endTime":1304.1,"type":"term","title":"factory transfer case is 84 pounds","url":"/glossary/factory-transfer-case-is-84-pounds","quote":"And so I got rid of, I think that factory transfer case is 84 pounds. Like as reference, a DHD is a hundred pounds...","canonicalId":"term:factory-transfer-case-is-84-pounds","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"Weight is a major factor in performance and durability, especially in motorsports.

How long the injectors pulsed on for?","canonicalId":"term:microseconds","priority":0.9,"confidence":0.95,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"Microseconds are a unit of time used to describe how long diesel fuel injectors stay open. In tuning, injector pulse width (how many microseconds the injector is commanded) is a direct way to control how much fuel enters the engine.","simplifiedExplanation":"Microseconds are just a very tiny unit of time. Here, they’re talking about how long the fuel injectors stay spraying fuel during each cycle."}},{"startTime":1387.9,"endTime":1390.4,"type":"term","title":"nitrous","url":"/glossary/nitrous","quote":"And then I had, I didn't have the nitrous all the way on. I had one.","canonicalId":"term:nitrous","priority":0.9,"confidence":0.95,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"Nitrous (nitrous oxide) is an add-on system that injects oxygen-rich gas into the engine to allow more fuel to burn. It’s commonly used in drag racing to create big, short bursts of power, and the timing/solenoid control matters a lot to avoid drivability issues."}},{"startTime":1501.2,"endTime":1504.9,"type":"term","title":"piston","url":"/glossary/piston","quote":"And so I was like, well, I'll just coat the piston as well. [1504.0s] You know, that makes sense.","canonicalId":"term:piston","priority":0.9,"confidence":0.95,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"The piston is the reciprocating part inside the engine cylinder that moves up and down to compress the air/fuel (or intake charge) and transfer force to the crankshaft. In high-stress builds, pistons are often coated or replaced to survive heat and cylinder pressures.","simplifiedExplanation":"A piston is the part inside the cylinder that moves up and down. It’s under a lot of heat and pressure, so builders sometimes use stronger pistons or add coatings to help it last."}},{"startTime":1556.9,"endTime":1556.9,"type":"term","title":"ceramic coating","url":"/glossary/ceramic-coating","quote":"We played with our coatings on there.

In drag/racing diesels, coatings can improve durability by lowering thermal stress and reducing the chance of overheating-related damage.","simplifiedExplanation":"A ceramic coating is a heat-resistant layer applied to parts like pistons. It helps keep the piston cooler and can make it last longer under hard use."}},{"startTime":1569.6,"endTime":1571.3,"type":"term","title":"total seal","quote":"They're not a total seal or anything special there. You don't want to try those.","canonicalId":"term:total-seal","priority":0.2,"confidence":0.5,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Total Seal” is commonly used to describe a premium piston ring brand/design known for improved sealing (often with special ring profiles). The speakers contrast their factory replacement rings against “total seal,” suggesting sealing quality affects power and reliability.","simplifiedExplanation":"“Total Seal” refers to a higher-end piston ring design meant to seal better. Better sealing can help the engine make more consistent power and reduce blow-by."}},{"startTime":1599.1,"endTime":1614.24,"type":"term","title":"horsepower","url":"/glossary/horsepower","quote":"So this time you're at 2100 horse, but you feel like you've done 25, 2600 on a PDD crank... it was going to be 25, 2600.","canonicalId":"term:horsepower","priority":0.9,"confidence":0.95,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"Horsepower is a common way to quantify engine power output. The speakers discuss target horsepower numbers (like 2100, 2500, 2600) and how the tune and hardware changes should translate into those figures.","simplifiedExplanation":"Horsepower is a number that describes how much power the engine can make.

Yep.","canonicalId":"term:good-rods","priority":0.5,"confidence":0.86,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Rods” are connecting rods, which transmit piston motion to the crankshaft. At high power levels, stronger rods (often upgraded materials or designs) help prevent rod failure from bending, stretching, or fatigue.","simplifiedExplanation":"Connecting rods are the parts that connect the pistons to the crankshaft. When an engine makes a lot of power, the rods have to be strong enough to survive the extra force."}},{"startTime":1772.3,"endTime":1777.9,"type":"term","title":"cylinder head","url":"/glossary/cylinder-head","quote":"And then the cylinder head, that's another fun thing for us.

In airflow-limited engines, that extra flow can raise the rpm where the engine can keep pulling efficiently.","simplifiedExplanation":"They’re saying the new head flows about 30 more units of air in testing. That extra breathing can help the engine keep making power at higher rpm."}},{"startTime":1817.1,"endTime":1819.5,"type":"term","title":"exhaust flow","url":"/glossary/exhaust-flow","quote":"Exhaust flow is actually in the realm. Might even be slightly less on this one than the last one.","canonicalId":"term:exhaust-flow","priority":0.5,"confidence":0.85,"source":"hybrid-fuzzy+gpt-5.4-nano","data":{"explanation":"“Exhaust flow” is the ability of the exhaust ports/valves to move spent gases out of the engine. Matching intake and exhaust flow is crucial because bottlenecks on either side can limit power and affect how well the engine scavenges at higher rpm.","simplifiedExplanation":"Exhaust flow is how easily the engine can push out burned gases. If the exhaust can’t keep up, the engine can’t breathe as well and power suffers."}},{"startTime":1933.0,"endTime":1937.9,"type":"term","title":"wet","url":"/glossary/wet","quote":"So a little over 4,400 pounds.
