The Compressor

After some research the Rotrex C30-84 supercharger was selected.  This was due to:

  • The compressor map being a good fit for the pressure ratios and mass flow rates required
  • Traction drive system provide a high 1 : 9.49 ratio allowing the electric motor to operate at speeds up to 10,000 rpm
  • Self-contained oil system (can be mounted anywhere in vehicle)
  • Packaging (compactness)
  • High mechanical and adiabatic efficiency
  • Low vibration and noise
90,000 rpm on the impellor should provide 11 psi at 2.55 g/s mass air flow
