BorgWarner EFR 9280 Turbo

The mack daddy of the EFR family, 9280 is the largest and highest power EFR turbo ever created.  A brand new release for BorgWarner Turbo Systems, EFR9280 uses a monster 73.7mm inducer and is intended for high power boost junkies that will push a turbo to the limit. This unique turbo uses the Black Series high flowing 91mm compressor exducer with 73.7mm compressor inducer and the massive swallowing capacity of their 80mm turbine.  Using the same 80mm Gamma-Ti turbine wheel from the EFR9180, this turbo spools early yet flows a whopping 110lbs/min of air at 117k RPM maximum shaft speed.
