BorgWarner EFR 9174 Turbo

BorgWarner EFR 9174 Turbo (12919097002)

The EFR9174 is a brand new release for 2016 from BorgWarner Turbo Systems. This hybrid turbo uses the lightweight alloy bearing housing derived from Indycar with a 67mm inducer compressor. EFR9174 is intended for applications which will push a turbo to the limit with high boost and critically high turbo shaft speed. This unique turbo was designed specifically by BW engineering to combine the high flowing 91mm compressor with fast spooling 74mm turbine wheel. The use of a 74mm turbine wheel allows for a max turbo speed of 125k RPM vs 116k for the bigger EFR9180.
