The largest and highest power EFR turbo ever created!

More Flow, more HP, more Performance but same series sizes. Along with increasing the wheel size, the compressor wheel blade shape and contour have been optimized to maximize flow while minimizing efficiency hits. BorgWarner also created a distinct compressor cover contour profile to maximize the air flow through the turbocharger. The new compressor wheels have been anodized black for visual impact and to differentiate the new models from existing EFR Series products. With the design changes to the compressor wheel and cover, the company's latest aftermarket parts will provide up to an extra 200 horsepower (hp) than was previously possible.

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 different sizes and different turbine housings, covering performance ratings from 250 to 1100HP.
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:
- black anodized 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 wheel and extremely heat resistant up to 1050°C (for comparison: Garrett only up to 950°C)
- high-flow wastegate port
- internal wastegate (also available for Twinscroll turbine housings!)
