BorgWarner EFR 9280 Turbo

BorgWarner EFR 9280 Turbo Brings Big Power Without Sacrificing Spool

The BorgWarner EFR 9280 is the Mack Daddy of the EFR family. This is the largest and highest-power-producing EFR turbo ever created. Proven in world class Time-Attack and back-to-back Formula Drift championships - the reputation of BorgWarner Turbo Systems is well-known, and the EFR 9280 is the turbo to get if you want responsive and fast spooling 1000+HP. The 9280 uses an aggressive trim with 73.7mm inducer and is intended for high-power race applications 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 swallowing capacity of their 80mm turbine stage. 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. If you're looking for a turbo that can give you 1,100hp+ without compromising spool or response - then this is one of the best turbocharger options out there.
