BorgWarner EFR turbocharger has been developed with only one goal in mind: to dominate road, racetrack and quartermile. BorgWarner EFR turbocharger are equipped with state of the art high-tech features for unbeaten performance.
EFR Turbos are available in 7 different sizes and 4 different turbine housings, covering performance ratings from 250 to 1000HP.
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 with metal cage
- 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!)
