Sick Summer 2026 Insanity Recap | Dustin West

Two-wheel drive (2WD) means power is sent to only one axle, typically the rear axle on many trucks. For drag racing, 2WD setups are often chosen to simplify traction management and drivetrain packaging compared with all-wheel-drive systems.

A short bed is a truck body configuration with a shorter cargo bed length. In drag builds, bed length can affect weight distribution and overall packaging, which can influence how the truck launches and how the chassis is set up.

The hosts discuss how a customer’s truck was selected and configured specifically for drag racing. They highlight the drivetrain and suspension choices that make it “fit” the drag-racing goal.

“Slicks” are race tires with no tread pattern, designed to maximize grip on dry track surfaces. They’re typically used for track days or racing because they wear quickly and aren’t meant for wet or street use.

“Trans” is short for transmission, the drivetrain component that transfers engine power to the rear axle. The transcript indicates the truck was missing both the engine and transmission during that build phase.

In this context, “motor” means the truck’s engine assembly that was missing at the time of the video release. The hosts are describing a build stage where the powerplant hadn’t been installed yet.

“Rear end” refers to the rear axle assembly and differential area of a truck. Pulling the rear end usually means opening up or removing that drivetrain section to perform modifications.

“Worley” appears to be a person or shop the host contacted for coordination during the build. The context suggests it’s an involved party in the project rather than a general automotive concept.

“Heads” are the cylinder heads—engine components that sit on top of the cylinders and control airflow and combustion. In diesel builds, specifying which cylinder heads are used is important because they affect performance, durability, and how the engine can be tuned.

The “Duramax” is General Motors’ diesel engine family, and “generation one” refers to the earliest version of that engine line. In diesel-performance circles, the first-gen Duramax is a big deal because it’s one of the most modded platforms and has a long aftermarket history.

“LB7” is a specific early Duramax engine code (an LB7-era 6.6L V8 diesel). When someone says “LB7 power Duramax,” they’re usually pointing out that the truck is running the LB7-generation engine, which matters because that engine has its own common tuning and upgrade paths.

In this context, “progression” means how the truck’s build evolved over time—starting from an earlier setup that felt dated, then moving through mods and refinements. It’s a common way enthusiasts discuss how a project becomes more competitive or better suited to the current goals.

A “twin kit” usually refers to a dual-turbo setup (or a dual-forced-induction package) rather than a single turbo. The exact hardware varies by builder, but the key idea is that two turbochargers work together to increase airflow and boost response.

Powder coating is a durable surface finish applied as a dry powder that’s then cured with heat. On performance parts, it’s often used to improve corrosion resistance and help components survive heat and road grime.

WC Fab appears to be a fabrication shop or brand that supplies aftermarket parts. In this context, it’s being credited for new components installed under the hood.

“Duramax” refers to GM’s diesel engine family, and a “tuner shop” is a specialist that reworks the engine’s fueling and calibration to make more power. In diesel builds, tuning is often paired with hardware upgrades like turbochargers and injectors.

“S400” is a turbocharger family designation commonly associated with larger, high-flow turbo builds. “Stealth” here sounds like a specific variant or custom configuration, but the key point is that it’s a performance turbo intended for big airflow and power.

LB7 is a specific GM Duramax diesel engine code used in certain early-generation Duramax trucks. It’s often referenced in performance builds because turbo, fueling, and internal parts choices differ by engine code.

“91 millimeter” is a dimension used to describe a turbo-related component size (commonly compressor or related hardware in turbo specs). In performance builds, larger millimeter ratings generally correlate with higher airflow potential, but they can also affect spool characteristics.

LMM is another GM Duramax engine code. It’s mentioned because the speaker’s prior setup on an LMM is used as a reference point for what the other truck’s turbo and configuration likely were.

“Carillo” refers to Carrillo (often spelled “Carillo” in speech), a brand known for aftermarket forged connecting rods and related rotating components. A “Carillo style setup” implies upgraded internals intended to handle higher cylinder pressures and power.

A “compound kit” is an aftermarket turbo setup that uses more than one turbocharger working together. In this context, “Whirly” refers to a specific brand/system that supplies the piping and components to make the compound arrangement work as intended.

“Compound kits” refer to aftermarket systems that arrange multiple turbochargers in a coordinated way (commonly to improve boost response and overall efficiency). The host is linking earlier compound technology to what modern compound setups can do today.

“Duramax” refers to General Motors’ diesel engine family used in trucks, best known for its strong aftermarket support and tuning potential. In this segment, the host is recognizing the truck as a Duramax when the engine is out, tying the build changes to a specific diesel platform.

A short block is the engine’s lower half—typically the crankshaft, pistons, and connecting rods—without the cylinder heads and often without the intake/exhaust. It’s a common way to describe what’s being reused versus replaced during an engine rebuild.

Fleece Performance is an aftermarket diesel parts brand known for cylinder heads and other performance components. In this segment, “Fleece heads” implies upgraded cylinder heads used to support the truck’s power goals.

A turbo kit is a packaged set of parts used to add or upgrade a turbocharger system on an engine. It usually includes the turbo, piping/intercooler plumbing, and related hardware needed to make the turbo work reliably.

A four-link is a rear suspension setup that uses four control arms (links) to locate the axle and control how it moves under acceleration, braking, and bumps. It’s commonly used on drag and performance trucks because it can improve traction and axle control compared to simpler suspension designs.

Axle tubes are the structural steel tubes that make up the housing for a live axle. In a build like this, welding and drilling axle tubes is a way to change axle strength, geometry, and ultimately fitment for larger axle components.

“Bigger axles” usually means upgrading to larger-diameter axle shafts and/or stronger axle components to handle more torque and traction. It’s a common move on drag or high-power builds because stock axles can twist or break under load.

A “12 wide wheel” refers to wheel width measured in inches, which strongly influences tire shape and contact patch. Wider wheels are common on drag setups because they allow the tire to sit correctly and generate more traction.

“31s” is shorthand for 31-inch tires, which affects ride height, gearing feel, and clearance. In this context, it’s part of the truck’s overall stance and traction setup (front vs rear tire sizes).

Torsion bars are a suspension spring system where a metal bar twists to provide ride height and springing. Ditching them for coilovers typically changes how the truck supports weight and how precisely you can tune ride height and damping.

Tubular arms are suspension control arms made from tubular steel (or similar materials) instead of stamped steel. They’re often used to improve strength-to-weight and to support more aggressive alignment and geometry changes in a performance suspension setup.

Coilovers are adjustable suspension components that combine a coil spring and shock absorber in one unit. Fabricating new brackets for coilovers usually means the suspension geometry or ride height target changed enough that the original mounting points didn’t work.

Suspension “geometry angles” refer to alignment and steering/suspension relationships like camber, caster, and toe that determine how the tires contact the road. Lowering a truck too far can push these angles out of spec, causing poor handling, uneven tire wear, or bump-steer.

Tire gap is the visible space between the tire sidewall and the wheel well/fender opening. Lowering and wheel/tire sizing are often tuned to reduce excessive gap for a cleaner stance while still maintaining safe suspension geometry.

Lowering spindles are aftermarket front suspension components that relocate the wheel/knuckle to reduce ride height without relying solely on cutting springs. They change the front suspension’s starting point, which can affect alignment and how much additional lowering is needed.

“Factory keys” here likely refers to factory ride-height adjustment parts (often small spacers/adjusters used to set spring perch height). The point is that even with lowering spindles installed, the truck was still sitting too high because the suspension wasn’t adjusted to the desired baseline.

A dyno is a dynamometer used to measure engine output (typically horsepower and torque) under controlled load. Asking whether the truck has been on the dyno is about verifying the power gains from the new setup rather than guessing from feel.

In this context, “Precision” refers to Precision Turbochargers, a well-known aftermarket turbo brand in diesel performance. The speaker is describing a custom turbo kit built around a Precision turbo.

The Dodge Charger is a full-size American performance sedan/coupe that’s known for big-engine power and a long history in motorsports and street performance. In a diesel-performance discussion, it may come up when talking about engine swaps, custom builds, or unusual “Frankenstein” setups that repurpose parts to chase specific performance goals. That kind of background makes it a frequent subject when people discuss precision fabrication and unconventional conversions.

A limited run means only a small number of units were produced, often making parts harder to find later. The speaker uses it to explain why rebuilding later was difficult—there weren’t readily available replacement components.

Fuel injectors are the components that spray diesel fuel into the engine’s combustion chambers. In performance builds, injector choice matters because higher boost and fueling demands can require injectors with different flow rates and calibration to keep the engine running correctly.

“Exergy pump” refers to an aftermarket high-pressure fuel pump brand/model used on diesel engines. The speaker is contrasting readily available “off the shelf” Exergy components with rare custom parts, implying the pump is a common upgrade path for these builds.

“Off the shelf” units are mass-produced, readily purchasable components rather than custom-fabricated parts. The speaker is emphasizing that modern diesel builds can be assembled from widely available parts, making replication easier.

A “hybrid 64” is a turbocharger configuration based on a “64” class turbo size, typically built by combining components to tune spool characteristics and airflow. In diesel circles, “hybrid” usually implies a custom mix of compressor/turbine parts to target a specific balance of response and peak power.

“Drag and drive” refers to events or a style of driving where the car is expected to do both: run drag-style acceleration and still be streetable enough to drive to and from the event. It’s a common theme in diesel performance communities because it rewards real-world usability, not just dyno numbers.

A “hybrid deal” here refers to a hybrid powertrain conversion package—adding an electric component to a vehicle that’s otherwise diesel-focused. The point is that the builder supplies a coordinated set of parts so the customer can replicate the setup without being a specialized fabricator.

“88” is almost certainly shorthand for a specific turbocharger size or model used in diesel performance builds, but the exact reference isn’t spelled out in this excerpt. It’s mentioned as part of a “twin kit,” implying it’s a key sizing choice for the build’s power/response.

“Emulate the drag truck” describes building a street/consumer truck to match the setup and performance goals of a known drag-racing truck. It’s about replicating the parts and configuration that make a drag truck effective, rather than just copying the look.

“UCC” is referenced as a place or program where the host suggests you need a very large budget to be considered. The excerpt doesn’t define what UCC stands for, but it’s clearly being contrasted with the more accessible parts-and-build approach described earlier.

A turbocharger is a forced-induction device that uses exhaust gas to spin a turbine, which compresses incoming air before it enters the engine. That extra air lets the engine make more power without needing a larger engine size.

Aftermarket seats are replacement or upgraded seats installed instead of the factory seats, often to improve support, comfort, or fit for a specific build. In performance trucks, they’re commonly paired with suspension upgrades and can affect how the truck feels during long drives.

Wheel horsepower is the amount of power measured at the tires (the wheels), after it passes through the drivetrain. It’s usually lower than engine horsepower because some power is lost in the transmission, driveshaft, differential, and tires.

“Spools” describes how quickly a turbocharger builds boost after you press the throttle. Faster spool generally improves throttle response and makes a high-power setup feel closer to stock in everyday driving.

“Driving manners” is an enthusiast term for how predictable and controllable a vehicle feels—especially around throttle input, traction, and shift behavior. Here, it’s used to claim the truck behaves like a factory-calibrated vehicle rather than feeling harsh or unpredictable.

Shift points are the engine speed/load thresholds where an automatic transmission decides to upshift or downshift. Tuning shift points can change how the truck feels—like whether it holds a gear longer for response or shifts earlier for smoothness.

Throttle refers to the driver’s request for engine power, typically via the accelerator pedal. In turbo/diesel tuning discussions, throttle position is closely tied to boost and torque delivery, which is why “over 50% throttle” can feel dramatically different.

Drivability is the day-to-day usability of a performance vehicle: how smoothly it responds to throttle, how predictable it is at low speeds, and how comfortable it feels in normal traffic. The speaker argues it’s a vague industry term until you’ve experienced a truly “undrivable” truck.

A “tune” is the engine control calibration (fueling, timing, boost targets, shift logic, etc.) that’s loaded into the vehicle’s ECU/TCU. “Tune issues” implies the calibration wasn’t working as expected—potentially causing drivability problems, power delivery issues, or triggering faults.

“Mechanically wrong” refers to a physical fault in the truck rather than an electronic/software problem. The speaker suggests they eventually found a hardware issue that likely existed earlier but wasn’t identified during the week.

“Great Lakes” here refers to a motorsports event location/venue in the Great Lakes region where the team was competing. The key point is that the failure happened during the event, not during normal street driving.

A checkpoint in racing logistics is a designated meeting point where teams can retrieve parts or support during an event. It’s part of how crews manage breakdowns and keep cars running between runs.

In this context, fittings are the specific connectors/adapter pieces that join transmission cooler lines to the cooler and hoses. Using the wrong fittings can prevent a proper repair and keep the system from sealing.

A Lexan window refers to a race-car safety window made from Lexan polycarbonate. It’s used to replace glass because it’s lighter and much less likely to shatter, which helps protect occupants during impacts.

In racing, a “cage” usually means a roll cage—an internal steel framework that strengthens the chassis and protects the driver in a crash. It’s also tied to rulebooks, where the required design depends on the sanctioning body and the car’s certification level.

Plexiglass is a common everyday name for acrylic or similar clear plastics used in racing windows. In motorsport contexts, it’s typically discussed as a replacement for glass to improve safety and reduce shattering risk.

A roll bar is a simpler safety structure than a full roll cage, typically providing rollover protection with fewer tubes and less coverage. In motorsport, upgrading from a basic roll bar to a full cage is often required to meet higher safety certification standards.

“10-0 cert” appears to be a shorthand for a specific roll-cage safety certification level used by a racing sanctioning body. The point in the conversation is that the basic roll bar setup would only meet a lower certification, so they upgraded the cage to a higher level.

In motorsports, “tech” is shorthand for technical inspection by officials before (and sometimes during) an event. They check safety equipment and rule compliance—like roll-cage configuration—so cars/trucks meet the event’s standards.

“Rear down bars” refers to roll-cage bars that run down toward the rear structure of the vehicle. In drag-racing and other motorsports, these bars are part of the safety cage and help stiffen the chassis so the car/vehicle can survive hard launches and impacts.

A “test pass” is a run made to evaluate how the vehicle is performing before or alongside official competition. Teams use test passes to confirm tuning, shifting behavior, and overall drivability.

“Shifting” refers to how a transmission changes gears under acceleration. When a truck “isn’t shifting,” it can indicate a drivability issue—like transmission control problems, clutch/band issues, or tuning that prevents the gearbox from making the expected gear changes.

A boost leak is an air leak in the turbo/supercharger pressurization system. When it happens, the engine can’t hold the intended boost pressure, which hurts power and can cause weird drivability and tuning behavior.

“Valley horn bolts” refers to the fasteners that clamp a component at the engine’s intake “valley” area (where parts meet and seals are used). If those bolts loosen or are missing, it can compromise sealing and contribute to leaks like boost leaks.

An O-ring is a rubber sealing ring used to prevent pressurized gases or fluids from leaking at a joint. If an O-ring gets eaten or damaged, it often points to a sealing surface issue or misalignment that can contribute to boost leaks.

A “base” is the main paint layer applied first, and “heavy silver base” suggests a thicker or more opaque silver base coat. This matters because it affects how the later color layers (like candy coats) look and how deep the final color appears.

Prismatic is a paint brand/line the host references for the “racing red” color used as the top coat. In enthusiast circles, specific paint brands and color names matter because they’re tied to how the candy/metallic layers behave.

A “candy” top coat is a translucent paint layer that’s designed to tint the color underneath rather than fully cover it. That’s why the host mentions metallic effects and why the base color (silver) strongly influences the final look.

“OEI” is an acronym the host uses in the context of someone reacting to the wheels, but the transcript segment doesn’t define what OEI stands for. Because it’s not standard everyday automotive jargon in this context, it would need clarification from earlier/later parts of the episode.

“20 inch” refers to the wheel diameter, which strongly affects stance, tire sidewall height, and how the truck rides and looks. “PYOs” again appears as the wheel’s designation, implying a specific wheel style/fitment the shop builds.

“Back ordering” means a supplier has run out of inventory and will fulfill orders later when parts become available. In this context, wheel companies can’t deliver immediately, which can delay builds and race prep.

“17 inch” refers to wheel diameter, and “PYOs” appears to be the specific wheel model/line being used to bridge the shortage. The key point is that they’re using a particular wheel size/option to keep the project moving while other wheels are unavailable.

“12.9” is almost certainly referencing a drag-racing time (typically elapsed time, ET) in seconds. The speaker implies a threshold (faster than 12.9) before slicks are worth putting on, which ties tire choice to expected performance.

“Six summer” appears to be the name of a specific event or series the hosts are discussing as part of the project’s competition schedule. It’s mentioned alongside “Michigan mile,” suggesting multiple events with different formats/locations.

“Michigan mile” refers to a one-mile drag-style event held in Michigan, where vehicles attempt top speeds and strong acceleration over a measured mile. It’s a common format for diesel and performance builds that want repeatable, measurable results.

Street tires are tires intended for normal road use rather than dedicated drag-racing slicks or track-only compounds. They can still be used for burnouts, but repeated aggressive use can quickly overheat and wear them down.

“Cords hanging out” means the tire has been worn or damaged until the internal fabric/steel reinforcement layers are exposed. That’s a safety-critical failure mode—at that point the tire can’t reliably hold air pressure or survive load and heat.

The Woodward Dream Cruise is a well-known Detroit-area classic car event on Woodward Avenue. In this segment, it’s used as an example of a Michigan checkpoint where crowds encourage burnouts.

A burnout is when a driver spins the tires while the vehicle is stationary or moving very slowly to heat up the tires and sometimes to show off traction. It can also be used to confirm tire grip before a run, but it’s hard on tires and drivetrain components.

Garrett is a well-known turbocharger manufacturer in the diesel and performance world. When someone says they want to “get rid of that Garrett,” they’re usually talking about swapping the turbocharger to change boost response, power potential, and how the engine behaves under load.
