Nissan Gtr
Car

Nissan Gtr

The Nissan GT-R is a fast all-wheel-drive sports car that’s famous for being hard to beat. In this segment, it’s one of the cars the guest’s team builds and tunes for racing.

Lamborghini Huracan
Car

Lamborghini Huracan

The Lamborghini Huracán is a high-end supercar with a powerful engine in the middle of the car. Here, it’s being used as an example of the kind of cars the shop builds and modifies for racing.

Audi R8
Car

Audi R8

The Audi R8 is a supercar with the engine mounted in the middle for better handling. They’re listing it as one of the cars they build for racing.

Term

fuel injection

Fuel injection is how the car sprays fuel into the engine. For making big power, getting the fuel delivery right is a big deal.

Term

injector dynamics

Injector Dynamics is a company that makes fuel injectors for performance engines. The guest is saying their shop handles part of the injector process, including work done before those injectors end up with customers.

Term

OEM grade

“OEM grade” means parts are built to match the quality and performance standards of original equipment manufacturer components. In the context of injectors, it implies the hardware is designed for consistent fueling and durability rather than being a purely experimental race-only item.

Term

flow bench

A “flow bench” is a device used to test how much fuel an injector delivers. It’s how people try to prove injectors are matched, but a simple bench test may not tell the whole story.

Term

flow matched

“Flow matched” means the injectors are picked so they spray fuel at the same rate. That helps each cylinder get similar fuel, so the engine runs smoother.

Term

static flow match

“Static flow match” means the injectors are matched at one specific test setting. But injectors don’t work the same way in every real driving condition, so this can miss differences that show up later.

Term

pulse width

“Pulse width” is how long the injector opens for each shot of fuel. If injectors behave differently at short vs long opening times, the engine can get uneven fueling.

Term

dynamically

“Dynamically” here means the injectors are matched based on how they perform across different operating situations. Instead of one test result, it’s about consistency across the range the engine actually uses.

Concept

you can't, you don't match injectors

The host is making a point that injectors have their own inherent behavior, so you can’t truly “force” identical performance across all conditions. Instead, the practical approach is selecting and pairing injectors that are tightly matched by measurement method (here, dynamic matching across pulse width).

Term

static flow rate

Static flow rate is how much fuel an injector delivers when it’s tested in a controlled way. Tuners use that number to estimate how much fuel the engine will get. If the injector’s flow rate is outside the stated tolerance, the tune may need adjustment.

Term

off spec injectors

“Off spec injectors” are injectors that don’t deliver fuel quite as accurately as the official spec says. They might flow a bit more or a bit less than expected. If you use them with a tune meant for perfectly matched injectors, the fuel mixture can be off.

Term

nicely matched set

A “nicely matched set” means the injectors are chosen so they behave similarly to each other. That helps the engine get consistent fuel delivery cylinder-to-cylinder. It’s especially important if the tune expects injectors to be very consistent.

Term

GM

GM is General Motors. Their cars use engine computers and tuning setups that may require data to be in a specific format.

Term

Chrysler

Chrysler is a car brand. Their engine computers can expect tuning data in different formats, so injector data may need to be prepared accordingly.

Term

AEM

AEM makes aftermarket engine computers and tuning gear. If you’re using an AEM ECU, the injector data has to be in the right format for that system.

Term

ECU

ECU just means the car’s engine computer. It’s what decides how the engine runs, and different computers can need information in different formats.

Term

plug and play

“Plug and play” means it’s set up so you can use it with little or no extra work. For tuning, it usually means the files/data are already in the right format for the computer you’re using.

Term

offset

An “offset” is a correction number used to make the fuel delivery match what the tune is asking for. It helps compensate for how injectors actually behave versus what the computer assumes.

Term

OEMs

OEMs are the car companies that make the vehicles. The point here is that even the factory has to calibrate injectors for how they actually behave, not just trust the injector brand’s marketing numbers.

Term

ID

“ID” here sounds like a way to refer to the injector’s specific identity or measured behavior. Instead of assuming all injectors of the same model behave the same, you use data from that particular injector. That helps the engine control system fuel more accurately.

Term

1650

“1650” is a label people use for how much fuel an injector can flow. It’s like a capacity rating, but real-world flow can differ depending on conditions. That’s why tuners may measure and calibrate injectors instead of trusting the label alone.

Term

cc's

“cc’s” is a way to describe how much fuel an injector can deliver. Think of it like measuring the injector’s fuel “throughput.” Tuners use this to pick the right injector size and to tune the fuel delivery correctly.

Concept

generate the data

This means measuring and creating the injector’s calibration information for your exact setup. Even if an injector has a published rating, real injectors can vary. So tuners generate their own data so the engine computer can command the right amount of fuel.

Term

800 horsepower

“800 horsepower” is a big power number. At that level, the fuel system has to be capable of supplying enough fuel, not just the engine parts themselves.

Term

1,500 plus range

The “1,500 plus range” means extremely high power. When you’re that high, you can’t just use any injectors—you need the right size and a tune that matches them.

Term

matched properly

“Matched properly” means the injectors are set up to work together as a consistent set. That helps the engine get the right fuel in each cylinder, which is especially important when you’re pushing big power.

Term

airflow

Airflow is how much air each cylinder pulls in. Since fuel needs to be balanced with air, different airflow can make some cylinders run richer or leaner.

Term

lambda

Lambda is a way to describe whether the engine’s fuel and air mix is correct. If you have lambda readings for each cylinder, you can adjust each one more precisely.

Lancia Lambda
Car

Lancia Lambda

The Lancia Lambda is an old car model from Lancia. It’s known because it was designed with some unusual engineering features for its time. It may be mentioned in a discussion about how car technology developed.

Term

EGT

EGT means exhaust gas temperature. It can hint at how combustion is going, but it doesn’t directly tell you the exact air-fuel ratio the way lambda does.

Term

air-fuel ratio

The air-fuel ratio is how much air versus fuel the engine uses. Getting it wrong can hurt power and can also increase heat and wear.

Term

500 CC injector

“500 cc” is a way of describing how much fuel an injector can flow. Bigger numbers usually mean the injector can supply more fuel for higher-power setups.

Brand

Bosch

Bosch is a well-known car-parts company. In this episode, they’re making the fuel injectors, and then the shop tests and prepares them so they’re ready to be used together.

Place

Arizona

Arizona is where the facility is located. The host is using it to explain where the injectors get built and prepared.

Term

laser engraving

Laser engraving is a way to permanently mark a part using a laser. Here it likely helps identify and track each injector through the build and testing process.

Term

break in

“Break-in” here means running the injectors through a controlled process first. It helps them settle into consistent behavior before they’re tested and paired for the engine.

Term

matched in sets

“Matched in sets” means multiple injectors are selected and calibrated so they behave consistently with each other. That matters because engines rely on each cylinder getting the right fuel quantity; mismatched injectors can cause uneven fueling and drivability issues.

Term

valve seat

The valve seat is the surface the valve seals against. If that seal changes slightly, the engine can let more or less flow through.

Term

injectors would be matched

Injector matching means making sure multiple fuel injectors spray the same amount. That helps the engine get the same fuel in each cylinder.

Term

rings

Rings are parts on the piston that seal the space between the piston and the cylinder. They also help keep oil under control, and break-in helps them fit the cylinder properly.

Term

fresh hone

Honing is a finishing process that roughens the inside of the cylinder in a controlled way. It helps the piston rings wear in correctly instead of just sliding on a smooth surface.

Term

48 injectors

Injectors are the fuel nozzles that spray gas into the engine. This setup can run a lot of injectors through a process—48 at a time—before they’re checked further.

Term

high duty cycle

Duty cycle is how often something is turned on during each repeating time period. “High duty cycle” means it’s on more of the time, so the injectors get more repeated actuation during the process.

Term

flow testing

Flow testing checks how much fuel an injector actually sprays. It helps confirm each injector is working correctly and consistently before you put it in the car.

Term

DI

DI means the fuel is injected straight into the engine’s cylinders, not into the air intake. Because of that, the fuel system parts have to be matched to the specific engine. It’s one reason high-power builds can need very specific injector setups.

Term

part number

A “part number” is basically the exact ID for a specific injector design. The host is saying that making a new injector design for direct injection is costly. So fewer engines end up using that exact injector.

Term

one injector per cylinder

This means each cylinder gets fuel from one injector. The host is saying that if you need more fuel for more power, you can sometimes add more injectors per cylinder. With direct injection, the setup is different, so you can’t just treat it the same way.

Term

inject a window

Fuel has to be sprayed at the right moment. If the engine only allows injection during a short time window, the injector can’t deliver as much fuel, so power gains get limited.

Term

200 bar

Bar is a unit of pressure; 200 bar is extremely high fuel-system pressure used in modern high-performance direct-injection setups. When you’re already near that pressure, there’s less “headroom” left to increase pressure to get more fuel flow.

Term

gas to ethanol

Gasoline and ethanol behave differently in an engine. Ethanol usually needs more fuel to make the same power, so you often need bigger injector/pump capacity, but it can also allow more aggressive tuning.

Term

port injectors

Port injectors spray fuel into the intake area before it goes into the cylinder. That can help the engine mix fuel and air more evenly, especially when conditions change.

B58
Car

B58

B58 is BMW’s turbo inline-six engine. The host is saying that BMW’s setup evolved so it uses fuel injection in the intake as well as direct injection, which helps fix issues that came with earlier DI-only designs.

Term

DI in port

“DI in port” means the engine uses direct-injection-style fuel delivery, but it’s aimed at the intake port instead of only spraying into the cylinder. That can help the engine mix fuel and air more consistently.

Concept

hybrid platforms

A hybrid platform is the car’s basic design that’s built to use both a gas engine and an electric motor. Because the car can rely on electricity sometimes, the engine and fuel system may need different tuning than a normal gas-only car.

BMW XM
Car

BMW XM

The BMW XM is BMW’s big, powerful SUV that’s also a hybrid. Because it’s hybrid, upgrades aren’t just about the gas engine—you also have to deal with the electric parts and their control systems.

Concept

aftermarket

“Aftermarket” means modifications you do after buying the car, like upgrades and tuning. The host is saying hybrids can be harder to modify because the car’s systems are more complex.

Term

turbocharge

Turbocharging adds a device that squeezes extra air into the engine. That can help the engine make more power, but you still need everything else to be tuned to work with it.

Term

electronics

Here “electronics” means the car’s computers and sensors that control how the engine and hybrid system work together. If you change performance parts, those computers often need to be handled correctly too.

Honda NSX
Car

Honda NSX

The 2017 Honda NSX is a hybrid supercar. The point here is that with modern hybrid electronics, it’s harder to modify than older cars, because the computer systems have to work correctly too.

Term

tuning a stock computer

“Tuning the stock computer” means updating the car’s factory computer so it controls the engine differently. For turbo cars, that usually changes how much boost and fuel the engine uses to make more power.

Concept

factory turbo hybrid stuff

This phrase means the car’s factory setup that combines a turbo engine with a hybrid system. The host is basically saying that because it’s all integrated from the factory, it can change how hard (or easy) it is to tune for more power.

Term

sequential transmissions

A sequential transmission is a gearbox where you shift through gears one-by-one in order. It’s common on serious builds because it can shift faster and more consistently than a regular manual setup.

Brand

6XD

6XD is a company that makes upgraded transmissions for performance cars. The host is saying their gearbox is strong enough to handle very high power.

Term

gearbox

A gearbox (transmission) is what lets the engine spin at the right speed while the car moves. For fast cars, it has to handle big power without failing.

Term

firmware

Firmware is the software stored in a car’s electronic control units (ECUs) that governs how systems operate. Updated firmware for cars like the GT-R and Huracán typically means revised calibration for engine management and drivability.

Term

cam control

Cam control is the computer adjusting valve timing using the camshafts. That changes how the engine breathes, which affects power and smoothness.

Term

Traction Control

Traction Control helps prevent the tires from spinning when you accelerate. It uses the car’s computer to cut power or brake certain wheels so you keep traction.

Term

torque modeling

Torque modeling is the ECU’s internal estimation of how much torque the engine is producing (and how it will respond). Modern ECUs use this to coordinate traction control and other stability systems, so firmware changes can require relearning the new control strategy.

Term

anti-lack functions

“Anti-lack” is a strategy to reduce a common drivability problem where the car feels like it’s lagging or falling flat for a moment. It’s the computer trying to keep torque delivery smoother.

Concept

calibration

A calibration is the tune—the settings inside the car’s computer that control how it runs. If the car’s computer changes with new firmware, the old tune might not work as well and may need to be redone.

Term

anti-lag

Anti-lag is a trick for turbo cars that helps the turbo stay “ready.” When you lift off the gas and then go back on it, anti-lag helps reduce the delay before boost comes back.

Term

throttle

Here, “throttle” means the gas control that affects how much air the engine can pull in. Anti-lag is designed to keep boost ready when you lift off the gas.

Term

drive-by-wire

Drive-by-wire means the gas pedal doesn’t mechanically move the throttle. Instead, sensors send signals to the computer, and the computer controls the throttle for you.

Term

brake pressure

Brake pressure is basically how hard you’re pressing the brake pedal. The car can use that information to decide how to manage boost and engine behavior.

Term

steering

Steering input tells the computer which way (and how much) you’re turning. The ECU can use that to adjust how it manages boost and engine torque.

Term

idle right

“Idle right” means the car runs smoothly when you’re stopped and not touching the gas. A tune can make the idle speed steadier and prevent weird surging or stalling.

Term

Mode Tech

Mode Tech is mentioned as the tuning setup that helps the car’s computer run correctly. The host is saying it makes it easier to dial in the car after adding performance parts.

Term

big injectors

Fuel injectors spray gas into the engine. “Big injectors” flow more fuel, so the car’s computer needs a tune to make sure it still runs right at idle and during normal driving.

Concept

docile street car

A “docile street car” is a car that’s tuned to feel calm and easy to drive day-to-day. It should idle smoothly and not act weird when you’re just cruising.

stock STO
Car

stock STO

STO is a more track-focused version of the Lamborghini Huracán. The host is basically asking: if you make a Huracán dailyable, do you lose what makes the STO special?

Term

big exhaust that runs under the car

A bigger exhaust system is designed to let the engine breathe more easily. It often makes the car louder, which is why the host connects it to the GT-R being loud.

Term

clunky

“Clunky” means the shifts feel rough or not very smooth. The host is saying the older GT-R gearbox doesn’t feel as refined as newer transmissions.

Term

DCT

DCT means a dual-clutch transmission. It uses two clutches so the car can switch gears very quickly, usually with smoother power than older automatics.

Term

Winolas

WinOLS is tuning software. Tuners use it to edit the car’s computer settings (calibration) so the car behaves differently.

Term

TCU tunes

TCU tunes are software changes for the transmission computer. They can make the car shift sooner/later and feel more aggressive or smoother.

Term

flash

“Flash” here means updating the car’s computer software. It’s how tuners apply new settings without swapping parts.

Term

TCU cal

TCU cal means the settings for the car’s transmission computer. Those settings control how the transmission and clutches behave, especially when you’re making big power.

Term

clutch pressure

Clutch pressure is how hard the transmission squeezes the clutch. If it isn’t high enough for the engine’s power, the clutch can slip instead of gripping.

Term

clutch will slip

Clutch slip means the clutch isn’t gripping hard enough, so it slips under acceleration. That can create heat and can damage the transmission if it happens repeatedly.

Term

TCU cow

“TCU cow” sounds like a nickname for an aftermarket transmission control add-on. The point is that it can change how the transmission applies clutch pressure when the factory settings aren’t enough.

Term

drag racing

Drag racing is a straight-line acceleration format where launch behavior and shift timing are especially sensitive to drivetrain calibration. The host is saying that for drag use, the transmission/TCU strategy (“how it launches”) will vary depending on whether you’re using factory vs modified control hardware.

Term

V10 market

A “V10” is an engine with 10 cylinders arranged in two rows that form a V. “Jumping into the V10 market” means they started working on performance parts for V10 engines.

Term

head studs

Head studs are stronger bolts that hold the cylinder head tightly to the engine. On big-power engines, they help keep everything sealed under high pressure.

Term

Pissons rods

Connecting rods are internal engine parts that connect the pistons to the crankshaft. The host is saying they used upgraded rods to handle more power.

Term

built blocks

A “built block” is a stronger engine foundation made to handle more stress than a stock engine. It’s what you do when you’re making a lot more power than the factory design.

Term

B series

Honda’s “B series” is a family of engines Honda used in a lot of performance cars. The point here is that when you push them for big power, you often need extra reinforcement like sleeves.

Term

sleeve it

“Sleeving” means installing stronger liners inside the engine cylinders. It helps the engine survive when you’re making a lot more boost and power than stock.
