RELIABLE

The Rotrex secret lies in its patented planetary traction drive. Smooth planet rollers, free from delicate teeth, ensure quiet mechanical operation, reduced vibrations, and reliable performance in all types of operations.

COMPACT

The small size and shape of Rotrex superchargers provide unique packaging advantages and installation flexibility. This is crucial in the compact engine compartments of modern vehicles.

BENEFITS OF ROTREX

  • Designed as belt-driven turbochargers, they are more efficient than conventional exhaust-driven turbochargers

  • Unlike exhaust-driven turbochargers, there are no restrictions in the exhaust path, resulting in cooler temperatures

  • Less heat means less fuel for tuning, meaning more fuel efficiency

  • Reduced heat also reduces the likelihood of pre-detonation, allowing for more ignition timing during tuning and, consequently, more power

  • Lubricated and cooled with an independent system, eliminating the need to tap into the original engine oil or coolant lines

  • Patented internal, planetary gear traction-drive system that is much smaller and more compact than any other supercharger available on the market

  • Easier and quicker to install than a traditional turbocharger, helping you save significant budget on labor costs

  • Keep your current full exhaust system, as installation doesn't require the fabrication of a complex exhaust turbo manifold

  • Available in gear-up ratios ranging from 1:7 to 1:13, it spins the turbines at speeds ranging from 90,000 rpm to as much as 240,000 rpm

UPCOMING APPLICATIONS
  • All 2-Cam, 16-Valve 928, 928 S and 928 Euro V8 models

  • All 8-Valve 924, 944 and 951 models

  • All 16-Valve 944 and 968 models

  • All 20-Valve 5-cylinder "07K" 924, 944 and 968 builds

If you don’t see your vehicle model listed, don’t worry, we’re currently developing additional kits for many applications.

On the Porsche 951 and 968 turbo cars, replacing the turbo setup with a Rotrex supercharger kit, eliminates the awkward, long, under-engine, cross-over boost pipe of traditional turbo installations!
