American supercharger kit specialist

KraftWerks is an American brand best known for supercharger kits for Japanese sports cars and tuner cars. The kits are typically based on centrifugal superchargers, which give a smooth power curve where boost rises with engine speed. The idea is to deliver a complete package with the brackets, piping and parts required, making the upgrade more manageable than a home-built project.

KraftWerks’ key products

The core of the range is complete supercharger kits supplied with the supercharger, mounting brackets, piping and the parts needed to deliver air to the engine. Many kits are available with or without an intercooler, or with different pulleys that determine boost level. KraftWerks also offers spare parts and upgrades such as belts, pulleys, oil supply and service parts for existing installations. Remember that a supercharger kit requires matching engine management. See each product for vehicle fitment.

Frequently asked questions

What is the advantage of a centrifugal supercharger?

A centrifugal supercharger delivers boost that rises with engine speed, so the car feels linear and predictable. It is often compact and produces less heat at low boost than many other supercharger types.

Does the engine management need tuning after fitting a supercharger kit?

Yes. The engine gets more air, so fuelling and ignition must be adjusted. This is done with a software update or programmable engine management, ideally by an experienced tuner.
