Kraftwerks Performance Group is a specialty performance brand that designs and manufactures advanced supercharger and forced‑induction systems for a wide range of import and enthusiast vehicles. Built around patented Rotrex traction‑drive superchargers capable of very high RPM and efficient boost delivery, Kraftwerks kits deliver significant horsepower and torque gains across the powerband with smooth, responsive performance. Each system typically includes everything needed for installation—precision‑engineered supercharger units, intercooler piping, front‑mount intercoolers, and fuel system upgrades—paired with durable hardware engineered for reliability. Whether on Hondas, Toyotas, Subarus, or other performance cars, Kraftwerks forced‑induction solutions offer enthusiasts powerful, usable power increases for street and track builds.

Kraftwerks supercharger systems are engineered around a patented Rotrex traction‑drive design that produces high shaft speeds and efficient boost with relatively low heat and noise compared with many traditional forced‑induction options. This setup provides broad, usable power gains and maintains drivability while supporting serious horsepower increases across a wide RPM range. The company’s focus on precision machining, in‑house engineering, and real‑world testing at their California facility ensures each system delivers dependable performance for both street and competitive applications.

Kraftwerks is a new company that has been focusing on the development of Rotrex superchargers, which replace the drive gears found in a traditional centrifugal supercharger layout with what is called a "friction drive system". This reduces heat and results in quieter operation. The Rotrex compressor is capable of revving extremely high and producing a linear powerband with instantaneous response. For those interested in proven technology with lots of potential, the Rotrex supercharger from Kraftwerks looks very promising!

Based out of Norco, California, Kraftwerk's superchargers are claimed to outperform any turbo or supercharger alternative on the market.

Q: Are Kraftwerks supercharger kits C.A.R.B. (California Air Resources Board) legal?
A: No, Kraftwerks supercharger kits are not C.A.R.B. approved and are not to be used on public roads where prohibited by law.
