BorgWarner EFR 9274 Turbo

BorgWarner EFR 9274 Turbo (12747100023)

Representing the next evolution of the wildly popular EFR9174, the EFR9274 is a brand new release for 2019 from BorgWarner Turbo Systems. The all new EFR9274 is intended for applications which will push a turbo to the limit with high boost and critically high turbo shaft speed. Recommended for competitive drift and time attack applications, this unique turbo was designed specifically by BW engineering to combine the high flowing 91mm compressor exducer with 72mm compressor inducer to allow the same footprint to breathe a LOT better up top. RPM Capabilities have also been improved with higher pressure ratios acheived at lower turbo shaft speed.  Using the same 74mm Gamma-Ti turbine wheel from the EFR9174, this turbo flows an impressive 106lbs/min of air at 125k RPM maximum shaft speed.
