About this episode

Cody Hawk talks through his second-year diesel competition push, including last year’s drivetrain failure and how the Duramax recovered enough to keep running. The crew lays out the build evolution—moving from a factory LB7 controller to a Bosch standalone setup—plus turbo and cooling upgrades aimed at track-ready power. With dyno testing, drag-strip passes, and a 2026 goal of “anything over 3000 horse again,” the team is chasing hardware while lining up event targets like Poland’s “make the hook.”

Technical Too Afraid to Ask
Term

main shaft

"Me and my guys had an awesome time. I guess I would say our only goal last year is to make sure it drove back into the trailer. And it didn't exactly do that as we snapped the main shaft and the trans, so we had to winch it in, but it was running."

A main shaft is a key rotating part inside the transmission. If it breaks, the transmission can’t send power to the wheels, so the truck can’t drive normally.

Term

trans

"And it didn't exactly do that as we snapped the main shaft and the trans, so we had to winch it in, but it was running."

“Trans” is shorthand for transmission, the drivetrain component that manages gear ratios and transfers engine torque to the wheels. In competition, transmission failures are common when power and torque exceed what the stock or lightly built drivetrain can handle.

Concept

winch it in

"And it didn't exactly do that as we snapped the main shaft and the trans, so we had to winch it in, but it was running."

“Winch it in” means pulling the truck with a cable when it can’t drive itself. It’s a recovery method after something breaks.

Term

power steering

"We had the engine spinning to utilize the power steering in the brakes and just no power to the ground."

Power steering helps you turn the steering wheel with less effort. Here, the host is saying the engine could still spin enough to run that system.

Term

brakes

"We had the engine spinning to utilize the power steering in the brakes and just no power to the ground."

Brakes are what slow the truck down. The host is saying the truck could still use its braking system while it was being recovered.

Term

Duramax

"As anyone on Facebook that owns a Duramax probably knows me by now. At least I would hope."

Duramax is the name people use for a Chevy diesel engine. It’s a popular engine to modify and race, so you’ll hear it a lot in diesel truck communities.

Term

chassis dyno

"Last year we ended up setting the Duramax world record for horsepower on a chassis dyno at 3140 with my guy Moore Luke behind the wheel."

A chassis dyno measures power and torque at the wheels while the vehicle is loaded and running on rollers. It’s commonly used for tuning verification and for comparing builds because it reflects real drivetrain output rather than just engine output on a test stand.

Concept

V8 platform

"And since then we have tried to push it and learn more as we go and try to put a V8 back on the podium at UCC. ...like you're the first V8 that I've interviewed. Everybody else has had Cummins motors."

A “V8 platform” here means a competition category/build centered around a V8 engine configuration rather than the more common diesel setups discussed in the episode. The hosts use it to highlight that the guest is competing with a V8 while others have different engine families (notably Cummins).

Topic

UCC podium push

"And since then we have tried to push it and learn more as we go and try to put a V8 back on the podium at UCC. ...it’s one Duramax versus 10 Cummins at a at a swing I feel."

They’re talking about trying to win (or place high) at UCC with a Duramax-based build. They also discuss how tough the competition is compared with other diesel setups.

Company

Dirty Hooker diesel

"And it seems like a lot of those advancements have taken place with the boys over at Dirty Hooker diesel. You have a good relationship with the guys over there."

Dirty Hooker diesel is a company/team that works on diesel performance. In this conversation, they’re helping with what the Duramax builder is doing for racing.

Topic

UCC and drag-strip preparation

"I remember the Saturday being at UCC and watching you and the crew thrash on the truck... Then after we're happy in the dyno. I'll have roughly two weeks of going to look drag strip just laying in some passes really getting acclimated to how it's set up now."

They’re talking about getting the truck ready for racing. That includes dyno testing and then practicing with drag-strip runs so the tune and setup work as expected.

Term

LB7 controller

"So that last year we were running a factory style LB7 controller. We got hooked up with the guys that actually this year and we went to a wash stand alone setup basically top tier control system you get the diesel game."

The LB7 controller is the truck’s factory computer for the diesel engine. It controls things like how the engine injects fuel, and it’s more limited than aftermarket tuning computers.

Term

stand alone setup

"We got hooked up with the guys that actually this year and we went to a wash stand alone setup basically top tier control system you get the diesel game."

A standalone setup is a different engine computer than the factory one. It lets the tuner control the diesel more directly and usually makes it easier to dial in performance.

Term

fine tune

"There's a lot more control. We're going to be able to see a lot more data and fine tune it in. Last year we had we had it together until each before UCC and right now we're three weeks ahead."

Fine-tuning means making small tweaks to the engine settings after testing. It’s how tuners dial in the tune so the truck runs right in real conditions, not just on paper.

LB7
Car

LB7

"So obviously I love my LB7 so it's an LB7 based RMAX 7-1 stock stroke big four built from the guys of the DHT."

LB7 is the name of a particular diesel engine used in some Duramax trucks. People like it because it’s common in the performance world, so there are lots of parts and tuning options for it.

Concept

stock stroke

"So obviously I love my LB7 so it's an LB7 based RMAX 7-1 stock stroke big four built from the guys of the DHT."

“Stock stroke” means the engine is using the same basic crankshaft throw as it came from the factory. It’s a way of building for power without changing that internal dimension.

Part

Rosler Turbo 400

"And we moved on from the 47 the DuraFlight the 47R8 the DuraFlight swap from the guys at Firepump and we ended up picking another transfer from the guys at Firepump, a Rosler Turbo 400."

The Rosler Turbo 400 is a turbocharger. A turbo forces more air into the engine, which helps the engine make more power—especially on a diesel when the fueling and tuning are set up to match.

Term

shaving about 4 to 500 pounds

"We're estimating we're shaving about 4 to 500 pounds on the truck."

Lighter weight helps the truck accelerate and stop more easily. Cutting a few hundred pounds can make a real difference on track.

Concept

3,000 horsepower

"[620.8s] which we talked about doing what I'm mentioning coming back from the less, [627.1s] guys at less performance fence out in Wyoming last year when we made our 3,000 horsepower. [632.6s] It was kind of like an off-handed comment. We're talking about it."

“3,000 horsepower” means the truck is making an enormous amount of power. Getting there usually takes a lot of upgrades, not just a simple tune.

Part

pull the engine out

"[641.9s] Mori Loge and Josh shot kind of just work. [644.8s] Said they're going to work on the truck for the weekend, pull the engine out, [647.5s] get it up so we can get refreshed and everything."

“Pull the engine out” means taking the engine out of the truck. That’s usually done when the work is too big to do with the engine still in place.

Concept

stop engine back in

"[688.0s] It's just a lot more extra work. If we wouldn't have done this, [690.8s] we would have had the truck ready to like three months ago. [692.7s] But we had to do a stop engine back in and go and it's a whole other level."

This means they took the engine out, then put it back in. After that kind of work, it usually takes extra time to get everything working right again.

Term

six 27

"You were eighth in racing. You ran a six 27. The truck made 1,930 horsepower."

In drag racing, people talk about how fast the car runs in seconds. “Six 27” means the truck ran in about 6.27 seconds for the race distance.

Term

100 miles an hour

"What happened from then to going on the dyno in Wyoming to make that big power number to you now, just like, Hey, like 100 miles an hour, all, all flames lit."

“100 miles an hour” is a speed reference likely tied to drag-racing trap speed (the speed at the end of the run). Trap speed helps indicate how well the car is accelerating and whether the power is being carried effectively to the finish.

Term

flames lit

"What happened from then to going on the dyno in Wyoming to make that big power number to you now, just like, Hey, like 100 miles an hour, all, all flames lit."

“Flames lit” means you can see flames coming out of the exhaust. It usually happens when the engine is running extremely hard, and it can mean a lot of heat and fuel is involved.

Term

pass

"So when I made that, that six 27 pass, that was my fifth pass ever on a drag strip."

A “pass” is just one run down the track during drag racing. Teams care because they want the car to do well repeatedly, not only once.

Car

Chevrolet Camaro

"...guys, they start with the old, old, like four gen Camaro or something. They got from their own foot and ma..."

The Chevrolet Camaro is a sports car that was made in different generations over many years. When people talk about older Camaros, they often mean the earlier versions that are popular to modify for more power or better performance. The podcast’s “four gen” comment is referring to one specific era of the Camaro model line.

Concept

full trial by fire

"And I kind of decided to do full trial by fire and try to put my, my full fully built race truck as fast as I could, but with no experience behind, behind the wheel."

“Trial by fire” here means jumping into high-stakes racing with little experience and learning through real competition. In motorsports, that approach increases the risk of mistakes and mechanical stress because the driver and setup haven’t been dialed in yet.

Company

DHT

"He's been day in, day out with me ever since we started this on the guys up at DHT. Again, they're one call away from answering anything I got..."

DHT sounds like the team or shop helping with the truck project. The speaker credits them for being available and supporting the build.

Part

feel injectors

"I got guys that dynamite build the, the biggest and baddest feel injectors on the planet."

Injectors control how diesel fuel is sprayed into the engine. Upgraded injectors are often used when people want the truck to make more power.

Company

Exergy

"Guys at Exergy, Jeff has been one call away ever since we decided to go down the Bosch route. [1128.5s] Bosch route."

Exergy is a company that makes performance parts for diesel trucks. Here, they’re being credited with fuel-system hardware that helps the truck make a lot more power.

Company

Bosch

"Guys at Exergy, Jeff has been one call away ever since we decided to go down the Bosch route. [1131.5s] They're awesome humans."

Bosch is a well-known parts maker for cars and trucks. In this episode, they’re talking about choosing Bosch components for the diesel fuel system.

Part

intercooler

"The guys that shied, we ended up getting one of their intercoolers this year. [1143.4s] It's quite cool. [1144.3s] It's quite beefy."

An intercooler is like a radiator for the air going into the engine. It cools that air so the engine can burn fuel more efficiently and handle more power.

Term

200 PSI

"It's quite beefy. [1146.3s] Hopefully it'll hold the 200 PSI we're planning to throw at it. [1152.3s] Yeah."

PSI is a measure of pressure. When they say “200 PSI,” they mean they’re planning to run the system at a very high pressure and want the parts to handle it safely.

Term

leak

"I'd say that all handed leak. [1154.2s] Right. [1154.7s] That's, that's the way we ended up seeing last year."

A leak in a diesel performance fuel/boost system can cause pressure loss, poor fueling/air control, and even safety issues. The segment suggests they previously saw a leak-related problem and are trying to improve the setup this time.

Topic

AMSOIL UCC

"But I think what I'm most looking forward to, if you can carve some time after the AMSOIL UCC, maybe we can schedule a time to get on another podcast and do it fresh"

AMSOIL UCC is a competition/event that people in diesel performance circles follow. They’re talking about doing another interview after that event.
