Borg Warner EFR 9280 T4 1.45ar Twin Scroll EWG Turbocharger
The largest and highest power EFR turbo ever created – EFR9280 is a brand new release for 2019 from BorgWarner Turbo Systems. EFR9280 uses a massive 73.7mm inducer and is intended for applications which will push a turbo to the limit. This unique turbo was designed specifically by BW engineering to combine the high flowing 91mm compressor exducer with 73.7mm compressor inducer and the massive swallowing capacity their 80mm turbine can deliver in a wide variety of turbine housings. Using the same 80mm Gamma-Ti turbine wheel from the EFR9180, this turbo flows a remarkable 110lbs/min of air at the same 117k RPM maximum shaft speed.
