Greg Alberalla Gives Tips for Upgrading a Cummins

The “stock engine block” is the factory cast engine block that comes from the manufacturer. When diesel trucks are heavily modified for higher power, the stock block can become the limiting factor because it may not tolerate the added cylinder pressures and stresses as well as stronger aftermarket hardware.

A “billet engine” typically means using billet-machined engine components (often for the block or critical internal parts) made from a solid piece of metal. In high-power Cummins builds, billet parts are used to improve strength and reduce the risk of failures that can happen when pushing a heavily modified stock engine block.

This segment references a “burnout competition” at UCC, which is a specific event where trucks are judged or tested on burnout performance. For builders, events like this influence how they plan upgrades because the truck needs to be reliable under repeated high-load launches and heat.

“Horsepower level” refers to the target power output the builder is trying to achieve. In diesel tuning, the horsepower number is often used as a shorthand for how much cylinder pressure and stress the engine and drivetrain must survive, which is why they discuss testing and data before raising it.

“Dynoing” means running a vehicle on a dynamometer (dyno) to measure things like power and torque under controlled conditions. For a Cummins build, dyno sessions help tune fuel/boost and verify changes before track or sled/drag testing.

Sled pulling is a motorsport where a vehicle pulls a weighted sled along a track, usually with increasing resistance. It heavily stresses the drivetrain and traction, so diesel builds often focus on torque delivery and durability for sustained load.

“ODSS racing” is a specific racing format/class referenced by the host as part of their competition schedule. Because the acronym isn’t expanded in this segment, it’s best understood as a particular ruleset/event type within their diesel racing scene.

The host emphasizes that a competition diesel build requires extensive preparation, not just quick upgrades and a few test passes. The key idea is that success depends on planning, iterative testing, and matching the build to the specific competition format and level of rivals.

Validation testing is the process of confirming that a modified build meets the performance and durability targets under realistic conditions. In high-stakes diesel competition, it often means repeated runs to find weak links before the event.

A turbocharger (“turbo”) forces more air into the engine by using exhaust gas to spin a turbine, which increases power potential—especially on diesel engines. When someone discusses a turbo in a build, they’re usually talking about matching turbo size, boost control, and fueling so the engine makes strong power without overheating or stressing components.

“Fleece” and “Freedom” are aftermarket diesel performance brands the host credits for engine-side parts and development support. In Cummins tuning/build culture, these companies are commonly associated with performance components and calibration work that help diesel engines make more power reliably.

Amsoil is a motor-oil brand the host uses in both competition engines and daily drivers. The key point is that oil choice matters for diesel builds because high power and heat can accelerate wear, so builders often rely on specific oil formulations and change/analysis routines to keep engines alive.

“Oil samples” refers to sending used oil to a lab to analyze wear metals, contamination, and oil condition. Builders use this to catch problems early and to verify that an engine is staying healthy under heavy loads.

SNS Diesel Motorsports is an aftermarket diesel performance brand the host credits with supplying “fuel system stuff.” On a Cummins build, the fuel system is critical because fueling strategy and hardware directly affect power, smoke, and engine stress.

A four-link setup is a rear suspension arrangement using four control arms to locate the axle more precisely than a basic leaf-spring or simpler link system. It’s commonly used on drag-focused diesel trucks because it helps control axle movement under hard launches, improving traction and stability.

An “850 cage” likely refers to a roll cage built to a specific safety standard or class requirement (the “850” is typically tied to a rulebook or vehicle category). Roll cages are used in high-power builds to protect occupants during hard launches or crashes, and they also add chassis rigidity.

“Fab” is shorthand for fabrication—custom metalwork like brackets, mounts, exhaust components, and other one-off parts. In a truck build, “Fab into things” usually means additional custom fabrication beyond bolt-on parts.

Yukon Gear & Axle is an aftermarket supplier that makes drivetrain components like gears and axle parts. On a Cummins or other diesel truck, upgrading these can improve durability and help handle higher torque from engine and turbo modifications.

A “72 millimeter turbo” refers to the turbocharger size, typically tied to the compressor wheel diameter. Larger turbos can move more air at higher engine speeds, which often enables higher horsepower—assuming the rest of the fueling and engine setup is matched.

A turbo upgrade means replacing the factory turbocharger with a different turbo setup to change how the engine makes boost. On diesel trucks, the turbo choice strongly affects spool characteristics (how quickly boost arrives) and the maximum power the engine can support.

“Stainless Diesel” is a company/brand name the host references as a supplier used on Cummins-related projects. The key point for listeners is that the discussion is about choosing reputable parts vendors when upgrading turbo and driveline components.

In a diesel truck, the transmission is the gearbox that multiplies engine torque and matches it to vehicle speed. When upgrading a Cummins, transmission choice and service support matter because power increases can stress driveline components.

The input shaft is the part of the transmission that receives rotational power from the engine (via the torque converter or clutch) and sends it deeper into the gearbox. When someone discusses an “input shaft” in the context of stronger builds, they’re usually talking about durability under higher torque.

“Freedom Racing Engines” is a referenced engine-building brand/team. The host is grouping it with other builders to emphasize that upgrade success depends on the underlying build philosophy, not just the parts list.

“Billet blocks” refers to engine blocks machined from a solid billet of metal, rather than cast from a mold. In high-power diesel builds (like Cummins upgrades), billet blocks are used because they can be stronger and more consistent, helping the engine survive higher cylinder pressures.

“Fuel system technology” covers the components and control strategies that deliver fuel to the engine—such as pumps, injectors, and how fuel pressure/timing is managed. Improvements here matter for diesel upgrades because they directly affect combustion quality and how much fuel the engine can safely burn under boost and high load.

“Testing equipment” refers to tools used to measure engine and tuning results—commonly things like dynamometers, datalogging tools, and pressure/temperature measurement. In diesel performance development, better testing helps builders validate safe power levels and diagnose issues before pushing further.

The speaker is describing a “package deal” approach to extreme power: you don’t just buy one part and expect reliability at the top end. Instead, you combine tuning strategy, instrumentation/data acquisition, and development time so you can identify what’s working and what’s failing under load.

Data acquisition is the process of collecting live measurements from an engine and drivetrain during testing or tuning. On a high-power Cummins build, it helps you see things like cylinder pressure, boost behavior, and temperatures so you can adjust safely instead of guessing.

This refers to the Cummins engine’s factory cast block (the main engine structure that houses the cylinders). In high-power builds, the cast block’s strength becomes a limiting factor—once cylinder pressures and stresses exceed what the casting can handle, you start seeing failures regardless of how much other hardware you add.

Nitrous fuel (nitrous oxide injection) is an add-on system that increases the amount of oxygen available for combustion, allowing much more fuel to burn and producing a large power boost. The speaker is saying they haven’t found data limits in the nitrous side yet, but the engine block strength still caps how far the build can go.

EGTs (exhaust gas temperatures) measure how hot the engine’s exhaust gets. They’re important on diesel performance builds because higher EGTs can indicate excessive fueling, poor cooling, or conditions that may accelerate wear.

A differential is the drivetrain component that allows the wheels on an axle to rotate at different speeds while turning. Differential fluid matters because it lubricates gears and bearings and helps manage heat under towing or high-power driving.

“Clean diesel fuel” means diesel that’s been filtered and treated so it contains very little water and debris. In a diesel pickup or commercial vehicle, fuel contamination can reduce power and accelerate wear in the fuel system.

This is a performance-and-ownership concept: improving diesel output while also reducing failures and wasted fuel. The host ties it to fuel cleanliness, arguing that contamination can cause both power loss and accelerated wear.

The Lucid Air is an electric luxury sedan built around battery-electric power rather than diesel or gasoline. It’s relevant to a diesel podcast segment because the discussion about removing water and vapor from fuel systems highlights how different powertrains handle “fluid” needs—diesels rely on fuel filtration, while electric cars rely on battery and thermal management. The mention likely ties back to filtration and contamination control concepts, even though the Lucid Air doesn’t use diesel fuel.

“Fast fuel systems” refers to an aftermarket fuel filtration/water-removal setup aimed at improving diesel fuel quality before it reaches the engine. The host claims it removes air and vapor and reduces water content while filtering out fine debris.

The host directs listeners to fastride.com to find an aftermarket “fuel system upgrade” for their truck. This is a brand/product callout tied to the earlier claims about water removal and fine filtration.

“Dermax” is a common nickname for the Duramax diesel engine family, associated with Chevrolet/GMC trucks. It’s widely discussed in the diesel tuning community because it’s known for strong aftermarket support and upgrade paths.

“Diesel performance” refers to how a diesel truck’s engine and drivetrain are tuned or modified to improve measurable outcomes like acceleration, towing strength, and drivability. In the diesel world, it often centers on increasing torque and optimizing fueling and boost.

A “race truck” is a vehicle built primarily for competition rather than everyday work use. That usually means more extreme engine tuning and supporting modifications, which can trade off some drivability, comfort, or long-term durability.

“Thousand horsepower” is a benchmark number in diesel tuning and drag-racing circles, meaning the truck is making at least 1,000 hp at the crank or wheels depending on the context. The speaker is contrasting older “upper tier” builds with how common very high-output trucks have become.

The Toyota Supra is a performance sports car known for its strong acceleration and driver-focused design. It often comes up in discussions about choosing the right “capability” for a build or upgrade path, because people compare how different power levels and setups change what the car can do. In a diesel-focused podcast, it’s likely mentioned as an example of matching engine output to the job you’re trying to accomplish.

The speaker is using “900 horsepower” as a practical threshold where Cummins builds often shift from a comfortable daily-driver goal to more of a specialized, high-stress setup. In diesel tuning culture, higher horsepower typically increases demands on supporting components and can make the truck feel less like an easy commuter.

“P-pump” is shorthand for the Bosch P7100-style mechanical fuel injection pump used on many older Cummins “12 valve” engines. Because it’s a mechanical pump system, it behaves differently than common-rail setups and is often discussed in the context of how power upgrades and drivability change with tuning.

“12 valve” refers to a Cummins engine family known for having 12 valves per cylinder head (as opposed to later designs). In the diesel world, it’s often discussed alongside specific injection hardware (like P-pump), and it’s commonly treated as a more old-school platform that can be strong but may be less straightforward to make high power and daily-drive-friendly than newer common-rail setups.

“VP 44” refers to the Bosch VP44 injection pump used on certain earlier-generation Cummins diesels. It’s a specific fuel-system component that enthusiasts compare against both 12-valve P-pump setups and later common-rail engines when discussing what’s practical for a reliable daily driver versus pushing extreme horsepower.

“Common rail” is a diesel fuel-injection system where fuel is pressurized and stored in a shared high-pressure rail, then delivered to each cylinder as needed. It’s known for more precise control of injection timing and pressure, which usually makes it easier to tune for power and can improve drivability compared with older injection layouts.

“6 7” is shorthand for the Cummins 6.7L diesel used in many Ram heavy-duty trucks. In this segment, the host argues that the 6.7L’s setup—especially turbo choices—can make the truck feel more responsive and enjoyable than a 5.9L.

“Turbos” are turbochargers—forced-induction devices that use exhaust energy to spin a compressor and push more air into the engine. In a diesel swap or upgrade, different turbo options can change how quickly the engine responds (spool-up) and how usable the power feels day to day.

In enthusiast talk, “platform” means the specific vehicle/engine generation and its underlying design that upgrades are built around. Here, the speaker claims Cummins owners are more resistant to changes in that platform compared with other diesel brands.

“Eight speeds” refers to an eight-speed automatic transmission, meaning it has eight forward gear ratios. More gears can help the engine stay in a more efficient or power-friendly range, which can improve drivability and fuel economy compared with fewer gears.

Aftermarket support means third-party parts and services sold outside the vehicle manufacturer—like upgraded components or fixes for known weak points. In this context, the host is saying that if a truck has a couple of common issues, the aftermarket already has solutions.

Fuel injectors are the components that spray fuel into the engine in precise amounts and timing. On a diesel like a Cummins, upgrading injectors can help deliver more fuel efficiently, which is one path to higher horsepower.

An engine dyno measures an engine’s output on a test stand. The engine is run under controlled load so you can quantify power and torque without the rest of the vehicle affecting results.

A chassis dyno measures power at the wheels while the whole vehicle is strapped down and driven by rollers. Because it includes drivetrain losses, wheel horsepower numbers often differ from engine dyno results.

Stock ECMs are the factory engine control modules with factory software calibrations. The transcript contrasts them with modern aftermarket engine control solutions, implying that factory control is less flexible for high-end tuning.

A catastrophic failure is a sudden, severe mechanical breakdown where the damage is extensive and often ends the engine’s life. The host argues that many of these events can be prevented by better electronic monitoring and control strategies.

Electronic safety devices are onboard systems that use sensors and control logic to detect abnormal conditions and reduce risk (for example, by limiting power or triggering protective strategies). The host’s point is that modern truck electronics can help prevent failures by catching problems earlier.

Cummins is a diesel-engine brand best known for heavy-duty inline-six engines used in trucks. In this segment, the host is talking about upgrading a Cummins by changing engine control hardware/software to avoid failures and improve reliability.

MoTeC is an aftermarket electronics brand known for engine management systems and standalone ECUs. In the context of upgrading a Cummins, the point is that a MoTeC setup can provide more control and better tuning than relying on stock calibration.

The “domino effect” here describes how changing one part of a diesel build (like engine control or base hardware) forces changes in other systems. For example, tuning on a factory block can limit how far you can push power, which then changes what engine builders and transmission builders can safely do next.
