Topic

Amsoil Ultimate Call Out Challenge 2026

UCC 2026 is a competition for diesel trucks. Teams race and test their trucks to see who can make the best runs while keeping the truck together.

Term

sled pull

A sled pull is when a truck tries to drag a heavy sled as far as possible. It’s hard on the truck in a different way than a straight-line drag race.

Place

Richland center in Wisconsin

Richland Center in Wisconsin is where he did some testing. Since it was on dirt, it can change how the truck grips compared to other surfaces.

Term

eighth mile

The “eighth mile” is a drag race distance—one-eighth of a mile. It focuses heavily on how hard the truck accelerates right off the line.

Term

shock settings

Shock settings are how you adjust the suspension dampers. Changing them can help the truck hook up and stay stable when it launches or hits bumps.

Term

change springs

Changing springs means swapping the suspension springs. It changes how the truck sits and how it squats or lifts under acceleration, which can affect traction.

Term

ODSS

ODSS is a name for a racing class or ruleset. It tells you what kind of diesel truck competition it was and what the rules were.

Term

670 index

“670 index” refers to a class/index number used in drag racing where competitors aim to run near a target elapsed time or performance index. Index racing helps level the field by rewarding consistency relative to the index.

Term

590

“590” is a class/index number used in diesel racing. It usually means the truck is competing under a specific target bracket or rules.

Car

2006 F250

A 2006 Ford F-250 is a heavy-duty pickup. Austin is using his F-250 as his race truck for diesel performance competitions.

six liter power stroke
Car

six liter power stroke

That “Power Stroke” is Ford’s diesel engine. When people say “six liter,” they mean a 6.0-liter version that’s popular for drag racing because it can be upgraded to make huge power.

Part

front rear forward link

That’s a special rear suspension arrangement. It uses link arms to control how the rear axle moves so the truck can launch harder and stay more stable.

Company

Warren diesel injection

That’s a company that makes and builds diesel fuel-injection parts. Here, they’re responsible for the injection setup on the race truck.

Company

Kade gather at max effort diesel

This is the shop/team that put the truck together. For a high-power diesel, assembly details matter a lot so everything works reliably.

Term

common kit

A “kit” usually means a set of parts meant to work together. Here it sounds like they’re using a packaged performance setup rather than piecing everything together from scratch.

Term

injectors

Injectors are what spray fuel into the engine. Bigger injectors can deliver more fuel, which helps make more power when the rest of the setup is built for it.

Company

SoCal billet

SoCal Billet is a brand of machined performance parts. “Billet” usually means parts made from solid metal, which can be stronger and more precise for racing.

Term

turbochargers

A turbocharger uses exhaust to push extra air into the engine. More air helps the engine burn more fuel, which is a big part of making high horsepower.

Term

nitrous

Nitrous is a system that adds extra oxygen to help the engine make a big power boost. It’s usually used for short bursts in racing, and it can be hard on the engine if the setup isn’t built for it.

Term

pro mod

Pro Mod is a drag racing class for cars/trucks that are heavily modified. It usually means the vehicle is built for serious, repeatable passes under racing rules.

Term

computerized stuff

That means they’re using more advanced engine computer tuning. The goal is usually to make power more consistent and safer for the engine.

Term

super flow dyno

SuperFlow is a type of dyno machine. The host is saying their biggest numbers came from that specific dyno, not from other test machines.

Term

common rails

A “common rail” is a diesel fuel system that keeps fuel under high pressure in a shared line. Then it sends that fuel to the injectors when the engine needs it, helping the engine make more power more precisely.

Term

high pressure oil pumps

Some diesel performance builds use oil pumps that make very high oil pressure. That high-pressure oil can be used to help control parts that need hydraulic force to work reliably when you’re making big power.

Term

ICP

ICP is the pressure the diesel system uses to control how much fuel gets injected. If ICP isn’t high enough or stable, the engine can’t inject fuel correctly—so power and consistency suffer.

Term

secondary low pressure pump

A “secondary low pressure pump” is an extra pump that helps keep fluid supply steady. Here it’s used to prevent oil from draining away, which helps protect the engine and turbo components.

Term

turbos

Turbos are forced-air devices that use exhaust gases to spin and push more air into the engine. They rely on good oil flow, so if oil supply is interrupted, they can wear out or fail.

Term

drag race

A drag race is a competition where vehicles race in a straight line to see who accelerates the fastest. It’s a good test of how well the engine and turbo can deliver power quickly.

Term

billet engine

A billet engine usually means some major engine parts are made from a solid block of metal. That can make them tougher for very high-power builds.

Term

fuel delivery

Fuel delivery is how the engine gets its fuel—how much and when. If it’s off by even a little, the engine can make less power or run poorly.

Term

roller

The roller is the part of the dyno that the truck’s drivetrain runs on. It helps the dyno apply resistance so you can test power under controlled conditions.

Concept

shake down

A shake down is an early test to make sure everything is working right. The idea is to find problems before the main event.

Term

regulator

A regulator is a device that keeps a system pressure at the right level. If it goes bad, the engine may not get the right pressure and won’t make the expected power.

Term

idle rail pressure

Diesel engines use a high-pressure fuel system. “Rail pressure” is how hard the fuel is being pushed to the injectors, and “idle rail pressure” is what it’s doing when the truck is just sitting and idling.

Term

PSI

PSI is a unit for pressure—basically how “strong” something is pushing. Here it’s used to describe how much pressure the fuel system is running at.

Concept

data logs

Data logs are recorded measurements from the truck’s sensors over time—things like rail pressure, boost, throttle position, temperatures, and engine speed. Teams use them to diagnose issues and verify that the tune and hardware are behaving correctly under real driving and racing conditions.

Topic

UCC

UCC is the name of the competition/event they’re preparing for. The key idea is doing well across the whole weekend, not just one quick run.

Topic

SS race

The host mentions the “SS race” as a different event where they know the other drivers/entries well. That helps them predict what competitors will do.

Term

power plants

Here “power plant” basically means the engine setup that makes the truck’s power. It can involve swapping to a different engine or a major rebuild.

Term

transmissions

The transmission is what sends power from the engine to the wheels. In high-power diesel trucks, it often needs upgrades so it can handle the extra torque without failing.

Term

standalone

A “standalone” is an aftermarket computer for the engine. Instead of relying on the factory settings, it lets the tuner control things like fuel and boost more precisely for racing.

Term

tuning

Tuning is adjusting the engine’s settings so it makes the power you want. For diesel performance, that usually means controlling how much fuel and boost the engine runs.

Term

big injector

Big injectors are fuel injectors that can spray more fuel than the factory ones. More fuel can be needed when the engine is modified for higher boost and more power.

Term

compound turbo

A compound turbo setup uses two turbochargers instead of one. That can help the engine build boost faster at low speed while still making strong power at higher speeds.

Term

1800 horsepower

Horsepower is how much power the engine can make. 1,800 horsepower is a huge number—this is the kind of power you’d expect from very serious drag-race builds.

Term

track calculated power

“Track calculated power” is an estimate of horsepower figured out from how fast the vehicle runs on the track. It’s not the same as a dyno test, but it helps compare builds.

Term

Gays

“Gays” sounds like it’s meant to be a place or track name. The point is they’re saying the truck has already run those speeds at a specific venue before.

Term

4,800 pounds

“4,800 pounds” is how heavy the truck is. Heavier vehicles usually need more power to accelerate and reach the same speeds as lighter ones.

Term

super stock world

“Super stock” is a drag-racing class/category with rules that limit or define how vehicles are built. The host is saying they’re currently operating in that ruleset while continuing to tweak parts and strategy.

Ford F-150 Lightning
Car

Ford F-150 Lightning

The F-150 Lightning is a pickup truck that runs on electricity instead of gasoline or diesel. It’s designed to do normal truck jobs like carrying things, but it uses an electric motor for quick power. People may mention it when talking about what happens if a vehicle breaks down during work.

Concept

underdog

“Underdog” just means you’re not the favorite going in. Here, the host is saying the 6.0L diesel was doubted, but it still proved it could run with the top cars/trucks.

Term

head gasket issues

The head gasket is a seal inside the engine that keeps hot combustion gases, oil, and coolant from mixing. If it fails, the engine can overheat or start mixing fluids, which can become a big (and expensive) problem.

Brand

Air Dog

AirDog makes diesel fuel-system parts, like lift pumps and filters. When a diesel is making big power, it needs steady fuel delivery, and these parts help with that.

Part

engine back in it

They’re putting the engine back into the truck after taking it out. That usually happens when the truck needed major work—either to fix something or to upgrade it.

Term

warranties on injection

Diesel engines use an injection system to spray fuel into the cylinders. A warranty on injection means the sponsor is offering coverage if injection parts fail, which matters a lot on modified high-power trucks.

Brand

Hot Shot Secret

Hot Shot Secret is a brand that makes products for diesel trucks, commonly fuel additives. They’re mentioned here because they offer a warranty related to the injection system.

Term

dirt drags

Dirt drags are drag races on dirt. Since dirt grips differently than pavement, the tires and how the truck delivers power matter a lot.

Concept

over build

“Over build” means you build the truck stronger than the bare minimum needed. That way it can handle racing without breaking and forcing you to redo the whole project.

Term

built transmission

A built transmission is a regular transmission that’s been strengthened and upgraded so it can survive harder driving. Even then, it can still fail if you push it beyond what it was built to handle.

Term

drag strip

A drag strip is a race track made for quick straight-line acceleration. It’s tough on the car because launches and repeated runs put a lot of stress on the drivetrain.

Term

hot lap

A “hot lap” means running hard repeatedly without much break. Doing that can overheat and wear out parts faster.

Concept

proactive refreshment before it becomes a failure point

Instead of waiting until something breaks, you replace or rebuild it before it fails. That way you can avoid bigger damage and usually spend less overall.

Term

head studs

Head studs are stronger bolts that hold the engine’s top (the cylinder head) tightly to the engine block. People upgrade them on heavily modified engines so the head stays sealed when things get really powerful.

Term

four wheel drive launching

Four-wheel-drive launching means you accelerate hard from a stop while all four wheels are driving. It can help you get traction, but it can still stress the transmission and other drivetrain parts a lot.

Term

input shaft

The input shaft is a part inside the transmission that takes power coming from the engine and starts sending it through the gears. If it breaks, the drivetrain can’t transfer power anymore, and repairs get expensive.

Term

six-liter platform

“Six-liter platform” means they’re focusing on a 6.0-liter diesel engine setup. It’s a way of saying the same basic engine family, so the upgrades and problems are similar across builds.

Car

six-liter power stroke

A “6.0L Power Stroke” is a Ford diesel engine (6 liters) that a lot of people modify for more power. It’s a well-known platform in the diesel community, especially for performance and competition trucks.

Term

lockups

Lockup is when the torque converter stops “slipping” and starts working more like a direct connection. That can make the truck feel more consistent and can help it stay efficient during hard driving.

Term

converter

A torque converter is part of an automatic transmission that helps the engine apply power to the wheels, especially when you launch. A bigger converter can change how the truck accelerates and how it behaves under heavy throttle.

Term

overdrive

Overdrive is an extra gear that helps the engine spin slower when you’re going fast. If you lose it, the engine stays at higher RPM, which can hurt how the truck accelerates.

Term

rev limiter

The rev limiter is a safety cutoff that prevents the engine from spinning too fast. If it hits the limiter right away, the engine isn’t making usable power and the run won’t go as expected.

Term

safety cut

A safety cut is the computer stepping in to protect the engine when something isn’t within safe limits. It can cut power suddenly, which makes the truck slower even if the driver is asking for more.

BMW 540S
Car

BMW 540S

The BMW 5 Series is a luxury car that’s meant to be comfortable for daily driving while still feeling quick. Depending on the version, it can have more powerful engines and better performance. It may be mentioned when someone talks about top speed or acceleration they’ve experienced.

Term

60 foot

60-foot time is how quickly the car gets down the first 60 feet after the start. It’s a big clue to how good the launch and traction are.

Concept

four second pass

In drag racing, a “pass” is a timed run. A “four second pass” means the truck/car completed the run in about 4 seconds, which is very fast.

Term

down rail pressure

On many modern diesels, fuel is kept under very high pressure in a “fuel rail” before it gets sprayed into the engine. If the pressure drops when you’re pushing hard, the engine may not make the power it should.

Concept

gremlins

“Gremlins” is a motorsports slang term for mysterious, intermittent problems that show up during testing or racing—like sensor glitches, fueling issues, or traction problems. They’re often hard to reproduce, which is why they can ruin a run even when the car/truck seems fine.

Term

weight limit

A “weight limit” is a rules-based minimum/maximum vehicle mass requirement for a racing class. Lowering the limit (as the speaker says to 4,000 pounds) can change how the truck accelerates and how teams tune power, gearing, and traction to stay within regulations.

Concept

hang weight

“Hang weight” means adding extra weight to the vehicle, usually as ballast. Racers do it to meet the rules or to help the truck hook up and launch more consistently.

Term

four nineties

“Four nineties” is a timing goal for drag racing—about 4.9 seconds for the run. It’s basically saying, “I want it to be in the high-4s.”
