Two Different Trucks, Two Top 5 Finishes. Where Will He Finish This Year? | Mike Brown AMSOIL UCC 2026

Sled pulling is a motorsport where a truck tries to pull a heavy sled across a track. Success depends on traction, torque delivery, and drivetrain durability because the load is constant and extremely demanding.

A transmission rebuild means disassembling and replacing worn or failed internal parts to restore proper shifting and strength. In high-torque diesel builds—especially for pulling or racing—rebuilds are common because the drivetrain takes repeated shock loads.

“Making horsepower” refers to tuning and modifying an engine so it produces more power at the crankshaft. In diesel performance, that usually involves boosting fueling and airflow and managing heat and drivetrain stress to keep the truck reliable under load.

“700 horsepower” is a benchmark number diesel builders use to describe a high-output build. Chasing big horsepower targets usually means more stress on the transmission, turbo system, fuel system, and cooling.

“Test and tune” at a drag strip is an event format where drivers make runs to dial in their tune-up—fueling, boost, tire pressure, and launch technique—before more competitive racing. It’s especially important for diesel builds because small changes can noticeably affect traction and elapsed time.

“P pump” refers to the Bosch P-pump fuel injection system used on many older diesel engines. When someone says it’s “700 horse,” they’re talking about the truck’s approximate power output (often measured at the wheels or estimated), which is a common brag metric in diesel circles.

“12 valve” describes an engine head design with 12 valves total—typically 6 cylinders with two valves per cylinder—commonly associated with certain classic inline-diesel setups. In diesel performance talk, it usually signals a specific generation of engine architecture that’s popular for tuning and upgrades.

UCC is a competitive diesel event/series where trucks are built and tested against each other, typically emphasizing drag-race performance and track results. In this episode, the speaker references his first UCC competition and his finishing position.

A “deck plate” in a truck build is a fabricated panel/plate used to modify the truck’s bed or mounting area—often to support a specific drag-racing setup or to package components. Here, the speaker says he “put a deck plate together” as part of the build.

“Gutted” means removing interior/bed components to reduce weight. In drag racing, weight reduction helps acceleration and can improve elapsed time by lowering the mass the engine has to move.

“Single wheel” indicates a single rear wheel setup rather than dual rear wheels, which changes traction and how the truck transfers power. In drag builds, wheel/tire layout is a key part of getting consistent launches and avoiding wheelspin.

“Lock up early” refers to a torque-converter clutch engaging sooner than ideal. When it locks too early, the drivetrain can fall out of its optimal operating range, which can feel like the truck “falls on its face” under load.

Bosch is a major automotive supplier of diesel fuel-system components and electronics. In performance diesel builds, switching to Bosch hardware can improve fueling control and consistency, which matters when you’re trying to make repeatable power and avoid drivability issues. Here, it’s described as a “game changer” tied to tuning and safety behavior.

“Dummy proof” is a performance slang term meaning the system is designed to be harder to mess up—typically via safety interlocks, better tuning logic, and more predictable behavior. In racing builds, that often translates to fewer catastrophic failures when the driver is staging, launching, or making repeated passes. The host ties it to “tuning stuff and safeties” that reduce the chance of “blowing it up.”

A “bigger intake” means increasing the airflow path capacity so the engine can draw in more air. On turbocharged or supercharged diesels, more airflow can support more fuel and higher power while helping combustion stay efficient. The host pairs it with other airflow and drivetrain changes to improve both speed and serviceability.

DNJ Enforcer refers to a specific DNJ performance product used on diesel engines, commonly associated with internal protection or durability-focused upgrades. In this context, it’s part of the host’s “bigger intake” and fueling/airflow changes aimed at making the truck faster without breaking parts. The mention suggests a targeted upgrade rather than a generic maintenance item.

Belt-driven indicates an accessory drive system where power is transmitted via a belt. Belt drives can be more compact and simpler, but they may be more sensitive to wear, tension changes, and heat under hard use. The host contrasts it with switching to a gear-driven case, implying durability and packaging improvements.

A gear-driven case refers to a drivetrain/auxiliary drive arrangement where components are driven by gears rather than belts. Gear drives are often chosen for durability and more consistent power transfer under high load, which matters during repeated drag-race launches. The host says switching to a gear-driven setup “cleaned up the front of the motor” and made it easier to work on.

ECM stands for Engine Control Module, the factory computer that manages engine operation. Cummins ECMs are the OEM (original equipment manufacturer) control units used on many Cummins-powered diesel trucks. The host says these factory ECMs are being replaced by standalone systems for better tuning control and safety protections.

OEM means original equipment manufacturer—the factory parts and factory calibration that came with the vehicle. In engine control terms, OEM ECMs are the stock engine computers. The host is saying the factory OEM control strategy is being replaced for racing-focused tuning and safety behavior.

A dyno (dynamometer) is a machine that loads a vehicle’s drivetrain so you can measure power, torque, and how the engine responds under controlled conditions. It’s especially useful for tuning because you can make changes and immediately see the results.

A rev limiter is an engine control feature that prevents the engine from spinning too fast (too high RPM). When the limiter is active, the ECU cuts fuel and/or spark to protect the engine, which can feel like a sudden “limit” even if the vehicle seems smooth.

In diesel performance, a “standalone” usually refers to an aftermarket engine control unit (ECU) that replaces or bypasses the factory computer. It gives tuners more direct control over fueling and boost, but it’s expensive and requires careful setup to get consistent results.

PMU here refers to a programmable power management unit used in performance diesel setups to control and distribute power for engine-related functions. In this context, the speaker says it helps “get rid of” other components on the truck and that the system includes a Bosch unit plus the PMU.

A transmission controller is the electronic control unit that manages how an automatic transmission shifts and behaves. It uses sensor inputs and software logic to command shift timing, pressures, and sometimes torque management during shifts.

Amps (current) measure how much electrical power a circuit draws. Monitoring amps per circuit helps verify that an output is actually activating (for example, confirming a nitrous system is drawing the expected current).

A data log is a recorded set of engine and vehicle sensor readings over time (often from the ECU). In performance tuning, it’s how you verify what actually happened during a run—like whether a system activated or whether fueling and boost behaved as expected.

Nitrous (nitrous oxide) is an injection system that adds oxygen to the engine, allowing more fuel to be burned for a power boost. In drag racing and diesel performance, tuners watch nitrous activation and related pressures to confirm the system is working correctly and safely.

Bottle pressure refers to the pressure inside the nitrous supply tank (“bottle”). If bottle pressure doesn’t stay up during a run, the nitrous system may not deliver the intended amount, which can change power output and air-fuel behavior.

“Fuel only” means the engine made power without any nitrous contribution—so the run relied solely on the fuel and normal air intake. This is important when diagnosing whether a “nitrous pass” actually used nitrous or if the system failed to activate.

Tuning is adjusting the engine control strategy (fueling, timing, boost/air management, and other parameters) to match the setup and goals. With performance diesels, tuning is often validated using dyno pulls and then refined using track data logs.

The Dodge Charger is a full-size American performance sedan that’s commonly used as a platform for diesel and forced-induction builds. In a performance podcast context, it’s likely being discussed around turbo/“charger” setup changes—like experimenting with different turbo configurations and manifold setups to improve airflow and power. That kind of talk matters because the turbo choice and plumbing strongly affect how quickly the engine builds boost and how much power it can sustain.

“Atmosphere” in this context is almost certainly a reference to boost pressure (often measured in psi or bar) used for engine tuning and performance testing. The speaker’s “115 atmosphere” phrasing suggests a specific boost level they’re targeting for the truck’s setup.

Taterbilt is referenced as the source of the truck’s “115 atmosphere” setup, implying a builder or tuner identity tied to this diesel performance build. In enthusiast circles, such names often represent a specific shop’s calibration or hardware package.

Drag racing is a straight-line motorsport where cars compete over a short distance to see who accelerates the quickest. In this context, they’re talking about how the truck’s power delivery and traction setup affect launch and acceleration.

Sled pull suspension refers to suspension setup and components optimized for pulling a weighted sled in motorsport. The goal is usually to control weight transfer and keep the tires planted so the truck can put engine power to the ground without excessive wheelspin.

In diesel performance, “compounds” usually refers to compound turbocharging—using two turbochargers in sequence (or combination) to improve boost response and efficiency across a wider RPM range. The speaker ties it to dyno testing, suggesting the turbo setup is a key part of how they’re measuring performance.

Traction bars are suspension links designed to reduce axle wrap and control how the rear axle moves under hard acceleration. They help keep the tires planted by limiting unwanted movement that can cause wheel hop or loss of traction.

The segment describes how diesel performance competition evolves as power levels rise over time. As more competitors adopt better fueling/airflow control and engine management, the “bar” for winning shifts upward, so teams must keep improving rather than staying with last year’s setup.

Shock adjustments are changes to the suspension dampers (often rebound/compression settings) to control how the truck squats, transfers weight, and settles during launch. In drag racing, getting the shocks right can improve traction and reduce wheel hop or instability.

“Idle and coast to 200 foot” describes a specific test format where the vehicle is not driven at full throttle the whole time. It emphasizes drivability and control—how well the truck maintains speed and stability after power is reduced—rather than only peak acceleration.

In multi-discipline competitions, “consistency” means performing well in every event (not just winning one). The speaker contrasts one-off peak performances with being the truck/team that stays reliable and competitive across drag racing, dyno, and sled pulling.

A flexplate is the thin, stamped metal plate that bolts to the engine’s crankshaft and connects to the torque converter on an automatic transmission. When it comes loose, it can cause driveline vibration or catastrophic failure that forces a teardown and repair.

Intake valves are the poppet valves that open to let the air/fuel mixture enter the engine’s cylinders. In this story, “spit intake valves out” suggests a severe valvetrain failure where valves were forced out of their seats, leading to major front-end engine damage.

The cylinder head is the top casting of the engine that houses the combustion chambers and the valve train (intake/exhaust valves, springs, and related hardware). Swapping a backup cylinder head is a common emergency strategy after a valvetrain failure to get the engine running again.

Pistons are the moving parts that travel up and down in the cylinders, compressing the charge and transferring combustion force to the crankshaft. After valve damage, pistons may need reshaping/clearancing so valves won’t collide with the piston crown during operation.

The BMW 5 Series is a mid-size luxury sedan that’s often discussed in performance circles because it’s a comfortable daily driver with strong engine and drivetrain potential. In a diesel-performance podcast, it may come up in the context of targeting specific power or performance goals (for example, aiming for certain horsepower or torque levels). That makes it relevant because tuning and hardware changes can significantly affect real-world drivability and stress on the drivetrain.

“60 foot” is the elapsed time it takes the vehicle to cover the first 60 feet from the start line in drag racing. It’s a key indicator of launch quality—traction, clutch/torque converter behavior, and how well the truck transfers power to the ground. Improving 60-foot times often leads to better overall quarter-mile or eighth-mile results.

A trans brake is a transmission control feature used in drag racing that holds the transmission in a locked state at launch. That lets the engine build boost/torque against the drivetrain so the car can leave the line harder and more consistently. It’s especially common on automatic transmissions in diesel and performance builds.

The “eighth mile” is a drag-racing distance of 1/8 of a mile (660 feet). Many tracks and diesel/drag events use it because it can be easier to run more passes and it highlights early acceleration and launch/shift quality. Times are often discussed alongside 60-foot and quarter-mile equivalents.

Practice passes are repeated runs on track to gather consistent data and build driver familiarity. The speaker emphasizes that more passes can produce the same amount of useful information as fewer passes if the setup and learning process are managed well.

“Adjust this bar” likely refers to tuning a suspension or chassis bar (commonly a sway bar or a linkage) to change how the truck handles during cornering or traction events. Small changes can alter weight transfer and how quickly the truck responds to steering and throttle.

Preloading is setting a component’s starting tension or position before a run so it behaves consistently under load. In track driving, it often refers to suspension or drivetrain setup so the truck responds predictably when it starts to “bite” and transfer weight.

Fuel injectors are the components that meter and spray diesel fuel into the engine under precise timing and pressure. In performance builds, swapping injectors can change how the engine atomizes fuel, which affects power, smoke, and drivability.

Flux is referenced as the supplier involved with the diesel injector work, specifically Don and April at Flux providing injectors used in the build. In this context, it’s a performance parts/vendor relationship.

“67 bodies” refers to injector body sizing/variant used in diesel injector setups. Changing the injector body can alter flow characteristics and how much fuel the injector can deliver, which is a common lever in diesel performance tuning.

Cornerstone is mentioned as part of the team the host credits for the overall build/support. Here it functions as a shop or contributor to the truck’s preparation.

firepunk is credited as a shop/team involved in the host’s diesel build and race preparation. The host describes them as accommodating and supportive when he comes in to work.

“Piping and fab work” means custom fabrication—cutting, bending, and welding tubing and components to build or modify the truck’s intake, exhaust, charge-air, or fuel plumbing. In performance diesel builds, this is often needed to fit upgraded parts and optimize flow paths.

“Air Dogs” are aftermarket fuel systems used on diesel trucks, typically to provide steady fuel pressure and improve fuel delivery. They’re commonly used when tuning for more power so the engine doesn’t starve for fuel under load.

A fluid damper is a device that uses fluid movement to reduce vibration and smooth out oscillations in a system. On diesel performance setups, it’s often used to tame driveline or fuel-system-related harmonics that can show up during hard acceleration and tuning.
