With the unique combination of compactness and efficiency, the Rotrex supercharger leads the way in drivable, high performance supercharged applications.
Where the efficiencies of the Roots- and screw-type superchargers trail off at higher pressure ratios, Rotrex continues to provide the best thermodynamic efficiency under extreme conditions. This has been demonstrated on a number of high performance applications, such as the Twin-charged Koenigsegg CCX and Koenigsegg CCXR.
Compared to traditional centrifugal superchargers, the Rotrex unit offers superior boost at lower engine speeds due to its inherent capability to accommodate high speed impeller designs. This virtue is essential for compact applications requiring more torque at low engine speeds than is usually achievable with centrifugal superchargers.
The Rotrex supercharger is standard on the Caterham Superlight R600, Caterham-Lola SP/300.R and the Caterham V8 Levante as well as the Castagna Aznom, the MELKUS RS2000 and the Spada Codatronca Monza.
