The combination of a high-efficiency compressor wheel, Gamma-Titanaluminid turbine wheel, with ceramic ball bearing technology dramatically raises the bar for motorsports turbochargers and is state of the art in terms of turbocharger technology:

Compressor:
- forged and milled compressor wheel, extremely lightweight and resistant to highest boost levels, Extended tip technology
- integrated blow off valve
- integrated boost solenoid
- 360° rotation via V-band technology
- prepared socket for speed sensor (optionally available) to monitor compressor wheel speed. Thereby compressor efficiency can be calculated.

Core assembly:
- dual ceramic ball bearing
- integrated oil restrictor
- water cooled

Turbine housing:
- stainless steel turbine housing
- Gamma-Titanaluminid turbine wheel and shaft, 50% lighter than comparable Inconel turbine wheeland extremely heat resistant up to 1050°C (for comparison: Garrett only up to 950°C)
- high-flow wastegate port
- internal wastegate (even available for Twinscroll turbine housing!)
