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.

SuperCores  are cartridges (CHRA) with compressor housing. They can be combined  with any turbine housings for this turbocharger. This is particularly  suitable if the desired configuration of the turbocharger with the  desired exhaust gas housing is not available directly or if you want to  use an turbine housing from a third-party manufacturer. In addition to  the cartridge, the mounting kit for the turbine housing as well as the  exhaust gas housing itself is always required. If the exhaust gas  housing has a wastegate flap, you also need an internal wastegate  actuator and a suitable holding plate.

Horsepower range: 500 - 950 PS

Compressor wheel: Inducer 68mm, exducer 84mm

Turbine wheel: 74mm

Turbine housing: None

BorgWarner EFR Turbocharger was developed and built with only one goal in mind: To dominate on the  road, race track and the 1/4 mile. BorgWarner EFR turbocharger features  the latest high-tech features, unbeatable performance and top quality.

EFR turbos are available in 8 different sizes and 7 different turbine housings, the power ranges from 250-1100HP.

The combination of high-efficiency compressor wheel, gamma titanium aluminide Turbine wheel combined with ceramic ball bearing technology sets the benchmark for  racing turbochargers to the top and represents the highest level in  racing sport turbocharging technology:

Compressor: 

- Forged milled compressor wheel

- Integrated compressor recirculation valve

- Integrated boost control solenoid valve

- 360° rotatable by Vband technology

-  Prepared for speed sensor (optionally available) for recording the  speed of the compressor wheel. There you can analyse the compressor  efficiency.

Cartridge: 

- Dual ceramic ball bearings

- Oil restrictor integrated

- Water-cooled

Turbine housing: 

- Stainless steel exhaust gas housing

- Gamma Titanium Aluminide Exhaust wheel and shaft, 50% lighter than a comparable Inconel Turbine wheel and extremely heat-resistant

- High-Flow Wastegate port

- Integrated wastegate (also available for the Twinscroll exhaust housings!)
