Auto Engine Components
Running the Right ECU

It’s important that the ECU you choose for your vehicle’s engine makes sense for its application. Many people are not aware that the stock ECU simply isn’t going to cut it it many performance applications.

Many engine builders have said Holley is a great ECU package for your wallet and your vehicle.
All About Timing Chains

If you’re building late-model dual overhead cam (DOHC) engines, you’ve probably noticed that a chain rather than a belt drives the camshaft. But why is this the case when chains are more expensive to produce?

Intake Manifolds for the Modern Age

Today’s aftermarket intake manifolds offer engine builders many options, but choosing the right one for your build is more than just finding the biggest one.

Adding Power with Superchargers

Superchargers have been in the market for a long time and there is a large variety to choose from to suit every need, car and budget.

Picking a Turbocharger Kit

Turbocharger kits come with many different parts that all require attention when buying. This is why searching through quality kits is important.

Diesel Transmission Upgrades

Diesel owners who add big horsepower, wheels and tires also need some driveline upgrades to keep it all together.

Diesel Injector Update

With today’s diesel injectors on the performance side, with nearly 35,000 psi of injection pressure, you can achieve a lot of quantity using that kind of pressure instead of just big spray orifices.

Powerstroke Upgrades

Marketed as the ICON series, these cylinder heads are a totally new, built from the ground up, clean sheet, USA design that will replace Kill Devil Diesel’s previous aluminum heads for Powerstroke applications.

Diesel Turbocharging

If you’ve ever seen a compound-turbo setup, you can clearly see it is not a twin-turbo setup. Why do diesels utilize compounds over twin turbochargers? We first need to move back to the basics of engine design and engine airflow consumption rates.

Piston Rings, Oil & Cylinder Wall Finish

A piston ring package is not only a seal for compression, it’s also controlling and distributing the oil on the cylinder walls of the block. The way a ring interacts with oil and the bore finish is critical to engine efficiency.

Induction System Science

The complexity of cylinder head set up and flow bench testing comes in the form of math, aerodynamics, thermodynamics, and the physics it takes to design the correct port and manifold design for a particular engine combination. These processes take years to master.

Motorcycle Valve Seats

As it related to valve seats, it is important to know a bit about the different materials used and when and where it is appropriate to use them.
