Company

6XD Gearbox

This is a company that makes or supports gearbox (transmission) parts. They’re sponsoring the show, so they likely have something to do with the kind of drivetrain builds being discussed.

Term

3000 horsepower

That’s the power level the guest is known for—about 3,000 horsepower. Making that much power on a diesel usually takes serious modifications, not just a simple tune.

Concept

horsepower to the tire

Horsepower to the tire means the power that actually reaches the wheels. It’s different from engine horsepower because some power is lost through the drivetrain.

Term

break the beams

On a drag strip, there are sensors that time your run. When you “break the beams,” it means you passed through those sensors and your time gets recorded.

Term

Sancher shaft, 37 splines

Inside the transmission, there’s a shaft that connects to other parts using ridges (“splines”). Stronger spline setups help the transmission transfer power without stripping or failing.

Term

full manual valve bodies

The valve body is like the transmission’s control center for shifting. A “full manual” setup lets the driver control shifts more directly, which can make performance more consistent in racing.

Company

Texas Motorplex

Texas Motorplex is a drag racing track in Texas. The speaker’s point is that the event schedule and distance affect how they manage repairs and swaps.

Concept

full manual valve body

A “full manual valve body” means the transmission shifts only when you command it. Racers use it to make shifting more predictable when the truck is making huge power.

Part

connecting rod

The connecting rod connects the piston to the crankshaft. When an engine makes a lot of power, the forces inside the cylinders get huge, so the rod has to be very strong.

Part

wrist pin bushing

The wrist pin is the small pin that connects the piston to the rod. A bushing is like a low-friction sleeve that helps it move smoothly and last longer.

Term

blown head gasket

A head gasket is a seal between the engine parts. If it fails, the engine can start mixing fluids or losing compression, and it can quickly get worse.

Term

head studs ARP 2000

Head studs are stronger bolts that clamp the engine together. ARP 2000 is a specific strong material/grade meant to handle high power without the head lifting.

Term

boost test

They test the turbo/boost system to make sure it’s working correctly. It helps confirm there are no leaks after the repair.

Term

compound turbos

Compound turbos use more than one turbo to get better airflow. The goal is quicker boost and more power across the rev range.

Term

roll cage

A roll cage is a metal safety frame inside the truck. It helps protect you if the vehicle flips or gets hit hard, and race rules often require one.

Term

time slips

A time slip is the paper (or digital record) that shows how fast you ran in a race. Race trucks are built to produce consistent, measurable results like that.

Term

dino graphs

Dyno graphs are charts from a testing machine that measure power and torque. They help you see if your tune is actually making the numbers you’re paying for.

Part

U joint safety shields

These shields protect the area around the driveshaft’s joint. If the joint breaks, the shield helps keep broken pieces from getting loose.

Term

drive shaft safety loop

This is a safety strap/loop around the driveshaft. If something breaks, the loop helps keep the broken parts from flying around inside the truck.

Part

chrome molly tubing

Chromoly tubing is a strong type of metal used for safety parts. It’s chosen because it can handle big forces without failing.

Part

360 degree loop

A 360-degree loop wraps all the way around the driveshaft. If the shaft breaks, it gives protection from multiple directions.

Part

CNC ported

CNC porting means the engine’s airflow passages are precisely reshaped with a computer-controlled machine. The goal is to let air and exhaust move more easily for more power.

Concept

front wheel drive

Front-wheel drive (FWD) sends power to the front wheels, which affects traction, torque steer, and how easily the drivetrain can handle extreme power. Building a high-horsepower FWD setup is especially challenging because the front driveline components and engine mounts see huge stress.

Part

valve spring

Valve springs control the opening and closing of engine valves and help prevent valve float at high RPM. The speaker mentions a “hundred pound valve spring,” which suggests much stronger springs than stock to handle the increased stress from the high-power setup.

Concept

cylinder head

The cylinder head is the top part of an engine that houses the combustion chambers and typically the valves and related passages. Replacing or installing a cylinder head is a major repair step and often happens after severe engine stress—especially in high-power diesel builds.

Term

human error

In high-power racing, “human error” refers to mistakes by the driver, tuner, or crew—like incorrect settings, missed steps, or wrong parts. Even when the hardware is capable, errors can still cause failures.

Term

nitrous

Nitrous is a system that adds extra “boost” to make more power. If it doesn’t turn on when you expect, you’re basically racing with less power than planned.

Part

turbochargers

Turbochargers force more air into the engine, which enables higher fuel burn and more power. The speaker mentions bringing many turbochargers, implying they swap setups to match track/dyno conditions or to recover from failures.

Term

helmet

A helmet is protective gear that helps keep the driver safe. They’re mentioning it because the driver is getting out of the truck after a race and needs to stay composed.

Company

Yukon gear and axle

Yukon makes heavy-duty drivetrain parts like gears and axle components. For a fast diesel truck, those parts help the drivetrain survive the extra twisting force.

Term

dyno

A dyno is like a treadmill for a car. Instead of driving on the road, the engine runs while a machine measures power, and it can also apply resistance to simulate driving load.

Term

boost pressure

Boost pressure is how hard the turbo is pushing extra air into the engine. More boost can mean more power, but it also needs the right tuning to stay safe.

Concept

Two turbos

Running two turbos can help the engine make boost sooner and still flow enough air at higher RPM. The exact setup determines whether it feels more responsive or more powerful at the top.

Company

Cummins

Cummins makes diesel engines. They’re talking about the idea of putting a Cummins diesel engine into a car like a Viper.

Audi
Car

Audi

Audi is a well-known car brand from Germany. They’ve also raced in major endurance events like Le Mans, and the speaker is bringing up their diesel racing history.
