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 - 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!)
