The EFR9174 is a brand new release for 2016 from BorgWarner Turbo Systems. This hybrid turbo uses the lightweight alloy bearing housing derived from Indycar with a 67mm inducer compressor. EFR9174 is intended for applications which will push a turbo to the limit with high boost and critically high turbo shaft speed. This unique turbo was designed specifically by BW engineering to combine the high flowing 91mm compressor with fast spooling 74mm turbine wheel. The use of a 74mm turbine wheel allows for a max turbo speed of 125k RPM vs 116k for the bigger EFR9180.
Compressor Housing Connections:
Using Borg Warner’s 91mm FMW compressor (67.7mm inducer) the 9174 houses our traditional 7 blade EFR extended-tip compressor wheel design capable of 94 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.
The EFR 9174 is available in (4) different turbine housing configurations:
1.05 A/R T4 Twin Scroll External-WG
0.83 A/R T3 Undivided (Internal WG)
