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.
CHRA features:
- 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 wheel and 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!)
