Greg Alberalla Gives Tips for Upgrading a Cummins
Term

stock engine block

The “stock engine block” is the original engine foundation that came with the truck from the factory. If you add a lot of power, that factory block can be the weak link, so stronger parts may be needed to keep the engine from failing.

Term

billet engine

A “billet engine” usually means some key engine parts are made from a solid chunk of metal and machined into shape. That can make them stronger, which helps when you’re trying to make a lot more power than the factory setup was designed for.

Brand

fleece and freedom

“Fleece and Freedom” are aftermarket brands associated with diesel performance parts, here specifically tied to a billet engine setup. In Cummins upgrade conversations, the brand names matter because different builders and part lines target different strength, machining quality, and compatibility for high-power builds.

Topic

burnout competition at UCC

They’re talking about a truck event where people compete by doing burnouts. If you’re building a truck for that kind of event, you have to make sure it can handle the stress and heat without breaking.

Term

horsepower level

“Horsepower level” is just how much power the truck is making. When people chase higher numbers, it also means more stress on the engine, so they want enough testing before pushing it at an event.

Term

dynoing

Dynoing is when you put the truck on a machine that measures how much power it makes. It’s used to test changes in a controlled way before you go race.

Term

sled pulling

Sled pulling is a race where your truck drags a heavy sled. The weight makes the truck work hard, so it’s a tough test for power and traction.

Term

ODSS racing

ODSS racing is a particular kind of race the host is talking about. The exact meaning of the acronym isn’t explained here, but it’s one of the event types they might run.

Concept

prep goes into a UCC type truck

They’re saying a serious competition truck takes a lot of prep. It’s not just bolt-on parts and a couple tests—you have to plan and test to be ready to win.

Term

validation testing

Validation testing means you test the truck repeatedly to make sure the upgrades actually work and won’t fail. It’s how you confirm the build is ready for competition.

Term

engine turbo

A turbo is a device that uses exhaust gases to spin a fan, which pushes more air into the engine. More air usually means more power, but it has to be tuned correctly so the engine doesn’t get too hot or stressed.

Brand

fleece freedom

Fleece Freedom is an aftermarket company that makes parts for diesel performance builds. The host is saying they’ve trusted their products for a long time and they help with the engine upgrades.

Brand

Amsoil

Amsoil is a brand of engine oil. The host is saying they use it because it helps protect the engine, especially when the truck is pushed hard.

Term

oil samples

Oil samples are when you take used oil and test it to see how the engine is doing internally. It can help spot wear or contamination before it becomes a bigger failure.

Brand

sns diesel motorsports

SNS Diesel Motorsports is a company that provides parts for diesel performance. The host is saying they supply the fuel-system components, which are important for making power safely.

Brand

hard way

“Hard way” appears to be a shop or builder the host credits with wiring up the truck after the fact. In diesel builds, wiring is often part of integrating engine management, sensors, and supporting systems for the turbo/fuel setup.

Term

four-link setup

A four-link setup is a type of rear suspension that uses multiple arms to hold the back axle in a controlled way. It helps the truck hook up better when you launch hard.

Term

850 cage

An “850 cage” sounds like a roll cage built to meet a certain safety rule for a competition class. A roll cage helps protect you if something goes wrong and can also make the truck feel more solid.

Term

Fab

“Fab” means custom fabrication—making parts from scratch or modifying parts for the build. It’s the kind of work a shop does when off-the-shelf parts aren’t enough.

Term

Yukon gear and axle

This refers to Yukon, a company that sells stronger drivetrain parts. In a diesel truck, those parts help the rear axle and gears survive when you add power.

Term

72 millimeter turbo

A turbo is what forces extra air into the engine. “72 millimeter” is a size measurement of that turbo, and bigger usually means it can support more power when the truck is built to use it.

Term

turbo upgrade

A turbo upgrade is swapping the stock turbo for a different one. That can change how quickly the truck feels like it’s getting power and how much power it can make.

Brand

stainless diesel

“Stainless Diesel” is a parts brand the host mentions for Cummins projects. The takeaway is to pick vendors you trust for quality and support.

Term

transmission

A transmission is the gearbox that helps the truck use the engine’s power efficiently. It’s especially important on diesel trucks because the engine makes a lot of pulling force.

Brand

dodge truck

“Dodge truck” here refers to Dodge’s pickup lineup, which commonly includes Cummins-equipped models. The host is framing a video about the weakest points in these trucks—specifically transmissions—so it’s a brand-specific reliability/upgrade discussion.

Term

input shaft

The input shaft is the transmission part that first receives power from the engine. If you’re making more torque, that shaft has to handle more twisting force, so it matters.

Brand

freedom racing engines

“Freedom Racing Engines” is an engine-building name. The point is that different builders have different approaches, and that affects how well an upgraded setup holds up.

Term

factory block

“Factory block” means the original, production engine block that comes from the manufacturer. In diesel performance builds, the factory block can be a limiting factor because it may not be designed to handle the extreme cylinder pressures and stresses associated with very high power levels.

Term

Billet blocks

A “billet block” is an engine block made from a solid chunk of metal that’s cut and shaped. People use it in high-power builds because it can be tougher and handle more stress than a regular factory block.

Term

fuel system technology

The “fuel system” is how the engine gets fuel and how precisely it’s delivered. Better fuel system parts and controls can help the diesel burn fuel more efficiently and support more power safely.

Term

testing equipment

“Testing equipment” is the gear used to measure what the engine is doing. For performance builds, it helps people confirm power and make sure the engine isn’t overheating or running dangerously.

Concept

package deal

They’re saying big power isn’t one magic upgrade. It’s a combination of the right parts plus careful testing and tuning so the engine stays together.

Term

data acquisition

It means using sensors and a computer to record what the engine is doing while it runs. That way you can see problems early and tune the truck based on real numbers, not just feel.

Term

factory cast commons block

The engine block is the big metal foundation inside the engine. When you push a Cummins to extreme power, the factory cast version can become the weak link and fail if the stresses get too high.

Term

nitrous fuel

Nitrous is a system that injects a special gas to make the engine burn more aggressively. It can add a big power jump, but it also increases stress on engine parts—especially the block.

Term

EGTs

EGTs means exhaust gas temperatures—how hot the gases are leaving the engine. If EGTs run too high, it can mean the engine is working too hard or not cooling well, which can hurt longevity.

Term

differentials

A differential is part of the drivetrain that lets your wheels turn at different speeds when you go around corners. The fluid inside it keeps the gears lubricated and helps prevent overheating when you’re towing or driving hard.

Term

clean diesel fuel

Diesel engines like fuel that’s as clean as possible. If the fuel has water or dirt in it, the engine can lose power and the fuel system can wear out faster.

Concept

maximizing power reliability and efficiency

He’s talking about getting the most out of your diesel truck in three ways: more power, fewer problems, and better fuel use. His point is that dirty fuel can hurt all three.

Lucid Air
Car

Lucid Air

The Lucid Air is a luxury car that runs on electricity. Instead of using diesel fuel, it uses a battery to power an electric motor. Because it doesn’t use fuel like a diesel engine, the usual fuel-filtering concerns don’t apply the same way.

Term

fast fuel systems

This is an add-on fuel system that cleans up diesel before it gets to the engine. The goal is to remove things like water and tiny particles that can cause problems.

Term

two microns

“Two microns” is a filtration rating that describes how small of particles the filter can remove. One micron is a millionth of a meter, so two microns is extremely fine filtration for diesel fuel.

Brand

fastride.com

They’re telling you to check fastride.com to look at a fuel-system upgrade product. It’s the company behind the “fast fuel systems” mentioned earlier.

dermax
Car

dermax

“Dermax” is slang for a Duramax diesel engine, which shows up in some Chevy and GMC trucks. It’s popular with modifiers because there are lots of parts and tuning options for it.

Term

diesel performance

“Diesel performance” just means how well a diesel truck can move and pull after upgrades. People usually focus on making it stronger and more responsive, especially for towing.

Concept

race truck

A “race truck” is built mainly to compete, not just to be a normal work truck. It often gets more aggressive modifications to make big power, which can come with trade-offs for daily use.

Term

thousand horsepower

“Thousand horsepower” is a big milestone number in the diesel world. It means the truck is making extremely high power, and the host is saying it used to be rare but now it’s more common.

Toyota A90
Car

Toyota A90

The Toyota Supra is a sports car made for fast driving. People talk about it when they’re discussing how much power you need for what you want to do with the car. The idea is that more capability helps you handle bigger goals or upgrades.

Term

900 horsepower

Here “900 horsepower” is being used as a rough line where a tuned diesel can stop feeling like an easy daily driver. More power usually means more stress on parts and more compromises for everyday driving.

Term

P-pump

“P-pump” is an older type of diesel fuel pump used on some Cummins engines. It controls fuel in a different way than newer systems, so it can change how easy it is to tune for power and how the truck drives.

Term

12 valve

“12 valve” is a way of describing an older Cummins engine design. Enthusiasts talk about it because the engine and fuel system are different from newer ones, and that affects how easy it is to make power and how it feels to drive every day.

Term

VP 44

“VP 44” is the name of a specific fuel injection pump used on some older Cummins diesels. Since it’s part of the fuel system, it affects how the engine makes power and how well it can handle heavy tuning for everyday use.

Term

common rail

Common rail is a modern way of injecting diesel fuel. It keeps fuel at high pressure in a shared “rail,” then sends it to the engine at the right time, which helps the truck run smoother and makes power upgrades more straightforward.

6 7
Car

6 7

“6 7” means a 6.7-liter Cummins diesel engine. The point here is that it can feel quicker to respond when you drive it, especially depending on the turbo setup.

Concept

swap project

A “swap project” is a build where you replace major components—here, an engine—into a different truck or configuration. The host’s point is that spending time and money on a swap only pays off if the final result is actually fun and usable to drive.

Term

turbos

“Turbos” are parts that help the engine make more power by forcing extra air in. The host is saying the turbo choice affects how quickly the truck feels like it’s responding when you drive it.

Term

platform

“Platform” here means the overall truck/engine setup people are working with. The host is saying some Cummins owners don’t like changing to newer setups as much as other groups do.

Term

eight speeds

This is talking about an automatic gearbox with eight different gear ratios. Having more gears can help the truck feel smoother and keep the engine in the right spot more often.

Concept

aftermarket support

Aftermarket support means non-factory parts or shops that can improve or fix the truck. The idea here is that if a model has common problems, there are already parts available to address them.

Term

injectors

Injectors are the parts that spray fuel into the engine. If you upgrade them, the engine can get the right amount of fuel more effectively, which can help make more power.

Term

electronic side

The “electronic side” refers to the diesel’s engine control electronics—things like sensors and the engine control unit (ECU) that manage fueling, boost, and timing. Changes here (often via tuning or new control strategies) can significantly affect how much power the engine can safely make.

Term

engine dyno

An engine dyno is a machine that runs just the engine and measures how much power it makes. It helps you compare changes like tuning or parts in a controlled way.

Term

chassis dyno

A chassis dyno measures how much power the car actually delivers to the wheels. It’s like testing the full vehicle on a treadmill with rollers.

Term

aftermarket ecu's and ecms

An ECU (engine control unit) and ECM (engine control module) are the vehicle’s computers that manage fueling, timing, boost, and other parameters. Aftermarket ECUs/ECMs replace or reprogram the factory calibration to give tuners more control for performance builds.

Term

stock ecms

Stock ECMs are the original factory engine computers. They’re programmed for normal use, so serious performance builds often want more tuning options.

Term

catastrophic failure

A catastrophic failure is when something in the engine breaks badly and usually causes major damage. The claim here is that better engine electronics can help stop that from happening.

Term

electronic safety devices

These are electronic systems that watch the engine and help protect it. If something goes wrong, they can reduce damage or stop the problem from getting worse.

Cummins
Car

Cummins

Cummins makes diesel engines that are common in heavy-duty trucks. Here, they’re talking about upgrades that change how the engine is controlled so you can reduce the chance of expensive problems.

Brand

mo tech

MoTeC makes aftermarket engine computers. People use them to tune how a diesel runs so it matches the upgrades they’ve done.

Term

Turbo guys

“Turbo guys” refers to builders and tuners focused on turbocharging upgrades, where the turbo’s airflow and boost control are central to how the engine performs. The host connects this to efficiency-focused development and the need for matching fuel and engine management changes.

Concept

domino effect

The host is saying that if you change one thing in a truck build, it affects other parts too. If the engine can’t handle more power, then the next upgrades—like the transmission—have to be reconsidered.
