The Kraftwerks 18-21 Mustang GT supercharger system provides instant throttle response and a linear power curve that increases all the way from idle to redline without the typical spiking or surging turbochargers are known for. This unique, more useable power curve results in reduced cylinder pressures, less strain on engine components, and increased reliability. Rotrex superchargers also operate much cooler when compared to turbochargers and other supercharger systems, which reduces the engine's intake air temperature as well as its risk of detonation. The heart of the system is the Rotrex C38-92, the largest supercharger offered from Kraftwerks, capable of supporting 700hp.
