SuperCore BorgWarner EFR-8374

Original EFR-SuperCore

Only Supercore without turbine housing

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: 475 - 750 HP
Compressor wheel: Inducer: 62.6mm, Exducer: 83,5mm
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 250-1000HP.
The combination of high-efficiency compressor wheel, gamma titanium aluminideTurbine 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 InconelTurbine wheel and extremely heat-resistant
- High-Flow Wastegate port
- Integrated wastegate (also available for the Twinscroll exhaust housings!)
