BorgWarner EFR 9280 Turbo (12807100005)

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.

Compressor Specifications

• • Compressor Type: Forged-Milled Wheel (FMW) Extended Tip
  • Compressor Wheel OD (exducer): 91mm
  • Compressor Wheel Inducer: 73.7mm
  • Max Flow Rate: 110 lb/min
  • Built-in BOV: All EFR compressor housings incorporate an integrated BOV.

Compressor Housing Connections:

• Inlet: 4? Ported Shroud Hose Coupler
• Outlet: 2.5? Hose Coupler w/ integrated Vband option

Using Borg Warner’s 91mm FMW compressor (73.7mm inducer) the 9280 houses our traditional 7 blade EFR extended-tip compressor wheel design capable of 110 lb/min airflow rate. Ceramic Ball Bearing only, watercooling optional (recommended). We strongly recommend using an EFR Speed Sensor if you plan to run to the limit.
