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
