aftermarket ECU
"You can always find our latest prize at hpacademy.com forward slash giveaway. It might be an aftermarket ECU or dash."
An aftermarket ECU is a new computer you can put in a car to change how the engine runs, like making it faster or smoother.
An aftermarket ECU (Engine Control Unit) is a replacement computer that manages engine functions like fuel injection and ignition timing, often used to tune performance or add features not available in the factory unit.
auxiliary injection
"But I did some auxiliary injection in the charge pipe, pre-throwed a body to get some extra fuel in there."
It’s a way to give the engine more gasoline by adding extra fuel in addition to what the main injectors provide, helping it run better or faster.
Auxiliary injection refers to adding extra fuel into the engine’s intake system, usually through a secondary injector or port, to increase power or compensate for limitations in the main fuel system.
water to air intercooler
"In stock form, you mentioned water to air intercoolers did obviously the sizing of those intercooler cores may have been problematic anyway."
Think of it like a tiny refrigerator for the air that goes into your car’s engine. It cools the hot air coming from a turbo or supercharger so the engine can run better and make more power.
A water-to-air intercooler is a heat‑exchanger that cools the intake air by passing it through a core filled with water, then letting the cooled air flow into the engine. It’s commonly used in high‑boost or drag racing setups to reduce intake temperatures and increase power.
dyno
"How well was that sort of controlling your, if you're ratio, if you sort of did a full ramp run on your dyno,"
A dyno is a machine that lets you see how much power your car’s engine makes by measuring it under controlled conditions.
A dyno, or dynamometer, is a device that measures the power output of an engine by applying resistance and recording torque and RPM.
boost levels
"We haven't actually talked about boost levels and power."
Boost is extra air pushed into the engine by a turbo or supercharger. It’s measured in PSI, like how much pressure is added beyond normal air pressure.
Boost levels refer to the amount of additional air pressure added to an engine’s intake system by a turbocharger or supercharger, measured in pounds per square inch (PSI). Higher boost increases engine power.
PSI
"It runs 32, 33 PSI."
PSI means how many pounds of pressure are pushing on each square inch of the engine’s air intake. It tells you how hard the turbo is working.
PSI stands for pounds per square inch, a unit of pressure used to quantify how much boost is being applied to an engine.
drivetrain differential
"What about the rest of the platform in terms of drivetrain differential?"
The differential is a part of the car that lets each wheel spin at its own speed, which helps the car turn smoothly. It’s an important part of how power gets from the engine to the wheels.
The differential is a gear assembly that splits power between the drive wheels, allowing them to rotate at different speeds during turns. It’s a key component of the drivetrain that affects handling and traction.
car axles
"start car axles"
Axles are the rods that connect each wheel to the car’s body and carry power from the engine to the wheels.
Axles are shafts that connect the wheels to the vehicle’s chassis, transmitting power from the drivetrain and supporting weight. They are fundamental components of a car’s suspension and steering systems.
drive shaft
"start transmission, start drive shaft, start differential"
The drive shaft is like a long axle that carries power from the transmission to the wheels. It’s what moves the car forward.
The drive shaft is a rotating component that transmits torque from the transmission to the differential, delivering power to the wheels. It’s a critical link in the drivetrain.
independent rear suspension
"And I think it's something that a lot of people drag racing over look when you've got an independent rear suspension."
Think of it like each back wheel having its own little suspension system, so bumps on one side don’t affect the other side.
An independent rear suspension allows each rear wheel to move separately, improving handling and ride comfort by isolating road irregularities.
engine tuning
"If you're a fan of the podcast and you're interested in topics like engine tuning, automotive wiring, performance engine building..."
It’s the process of changing how the engine runs to make it faster, smoother, or use less fuel.
Engine tuning involves adjusting the engine’s parameters—such as fuel mixture, ignition timing, and boost pressure—to optimize performance or efficiency.

3D modeling and CAD (Computer-Aided Design) are digital tools used to create detailed three‑dimensional representations of parts or assemblies for design and manufacturing.
sprockets
"In terms of adapting, again, the motorcycle is running a chain drive and sprockets."
They’re the toothed wheels that fit onto a chain, helping move power from one part to another.
Sprockets are toothed wheels that mesh with a chain to transfer rotational motion, similar to gears.
chain drive
"In terms of adapting, again, the motorcycle is running a chain drive and sprockets."
It’s a metal chain that carries the engine’s power to the back wheels, like the chain on a bike.
A chain drive uses a metal chain to transmit power from the engine’s output shaft to the rear wheels, common in motorcycles and some bicycles.
piggyback ECU
"[2495.0s] And I have a piggyback spliced into that ECU."
A piggyback ECU is a small computer you add to your car’s existing engine computer. It lets you change how the engine runs, like adding more power or making it run smoother, without having to replace the original part.
A piggyback ECU is an aftermarket device that sits alongside the factory engine control unit (ECU) to modify or add functions such as boost control, fuel mapping, or other performance tweaks without replacing the original ECU.
turbocharging
"Obviously when you're turbocharging an engine, the fueling is critical, but so is the ignition timing."
It’s like giving your car a boost by sucking in extra air so the engine can burn more fuel and make more power.
Turbocharging is a method of forcing more air into an engine’s combustion chamber using exhaust-driven turbines, increasing power output without enlarging the engine size.
ignition timing
"How has that been dealt with with this piggyback? Are you modifying the ignition timing and retarding it with boost?"
It’s the timing of when the spark plug lights up inside the engine; getting it right helps the car run smoothly and powerfully.
Ignition timing refers to the exact moment when the spark plug fires in relation to the piston’s position, crucial for efficient combustion and engine performance.
boost pressure
"I'm actually not retarding any timing right now because I'm running such low boost pressure."
Boost pressure is how much extra air a turbo or supercharger pushes into the engine. More boost usually means more power.
Boost pressure refers to the amount of air forced into an engine’s combustion chamber by a turbocharger or supercharger, measured in psi or bar. Higher boost increases the engine’s power output.
clutch
"When I first turboed it, I did have a problem with the clutch and funny enough,"
The clutch lets you shift gears by connecting or disconnecting the engine from the wheels, so the car can change speed smoothly.
The clutch is a mechanical device that engages and disengages the engine from the transmission, allowing gear changes without stalling.
Honda
"I kind of picked the wrong generation CBR because most leader bikes they have individual coil springs"
Honda is a company that makes cars and bikes; they’re famous for building things that last long and run smoothly.
Honda is a Japanese automotive manufacturer known for producing reliable motorcycles, cars, and power equipment.
cam timing
"because obviously when you change the airflow into the engine with the cam timing,"
The camshaft controls when the engine’s valves open and close. Changing its timing can make the car run smoother or faster, but it needs careful tuning.
Cam timing refers to the precise moment when the engine’s camshaft opens and closes the intake and exhaust valves. Adjusting it changes airflow timing, affecting power, efficiency, and emissions.
manifold
"[3584.0s] But the manifold that they made was all fully welded. [3606.0s] What sort of considerations do you have around how to deal with manifold expansion and contraction as it heats up and cools down?"
A manifold is like a pipe that sends air to each part of the engine’s cylinders. It’s made solidly here so it doesn’t have loose parts that could break.
The manifold is the component that distributes air (or fuel and air) from the intake system to each cylinder in an engine. In this context it’s a fully welded, short unit designed for a horizontal opposed engine.
horizontal opposed engine
"[3591.0s] And obviously on our horizontal opposed engine, you've got quite a long run from one side to the other. [3596.0s] That was a low mount kind of like you're saying there."
A horizontal opposed engine is a type of engine where the cylinders lie flat on either side of the car, like a pair of pistons moving in opposite directions. It keeps the engine low and smooth.
A horizontal opposed engine, also known as a flat or boxer engine, has cylinders arranged in two banks on opposite sides of the crankshaft. This layout lowers the center of gravity and reduces vibration.
wheel horsepower
"So yeah, maybe 300 wheel horsepower. And then maybe later I'm sure I'll get the edge and probably throw some rods in it or something and try to make 400."
Wheel horsepower tells you how much power actually reaches the wheels, not just what the engine makes. It’s a useful number for comparing real-world performance.
Wheel horsepower is the power measured at the vehicle’s wheels, accounting for losses in the drivetrain. It’s typically lower than engine (gross) horsepower because of friction and gear ratios.
gearbox
"The only other thing I would say about them is fourth gear in those gearboxes is a massive weak point."
A gearbox is the part of a car that lets you change gears, like shifting from low to high speed. It helps the engine run efficiently at different speeds.
A gearbox is a mechanical assembly that transmits power from the engine to the wheels, allowing the driver to select different gear ratios for varying speed and torque needs.
wastegate
"And then in fourth gear, I think we pulled it back to waistgate, which was maybe like seven psi."
A wastegate is a valve that stops some exhaust from going to the turbo, keeping the engine from getting too much boost and staying safe.
A wastegate is a valve that limits the amount of exhaust gas reaching the turbocharger, controlling boost pressure and protecting the engine.
