Kraftwerks Performance Group is proud to bring you the most advanced supercharger system available. At the core of each Kraftwerks supercharger kit is the revolutionary and patented Rotrex, traction-drive supercharger. The proprietary design allows for reduced weight; smaller, quieter, cooler operation; and shaft speeds in excess of 200,000 rpm. No other forced induction method can compare to Rotrex’s superior efficiency, unmatched performance, reduced emissions, and transient response. Kraftwerks supercharger systems are designed to deliver broad, usable power gains—ideal for street cars and track cars alike. No other supercharger kit or turbocharger system can compare. Kraftwerks supercharger kits represent the pinnacle of forced induction, having demonstrated gains in excess of 100% across the entire powerband on a number of applications. Each Kraftwerks supercharger kit is designed in-house at our state-of-the-art, Norco, Calif., facility with applications available for a variety of vehicles. Today we continue our tradition of creating leading-edge products through a state-of-the-art engineering and R&D department as well as through extensive engine development and testing both on the race track and the street.
