Borg Warner 9180 EFR Turbo 600-1000 HP. Borg Warner  9180 EFR Turbo is the biggest, baddest, highest flowing turbo in the EFR  family. Capable of a remarkable 95lb/min airflow and stable at very  high boost levels, the 91mm OD compressor measures 68mm inducer and is a  7 blade FMW compressor. This turbo will redefine what 67mm turbos are  capable of. After receiving requests from many high power enthusiasts  and drag racers restrained to a 67mm inducer, there was a clear need for  1000hp capable turbos that still provide good spool and response. Using  the high flowing 1.05 a/r Twinscroll T4 turbine housing is the most  efficient way to run this as a single turbocharger. If twin turbos will  be run, the .83 a/r or 1.05 a/r can be used, depending on manifolds and  space constraints. Ideal for use as single turbo applications in the  600-1000hp per turbo range, or as very high power twin turbo  applications >1000-1700+hp. Available with .83 a/r undivided T3  internal WG or 1.05 a/r divided twinscroll T4 housings (external WG).  Ceramic Ball Bearing only, watercooling optional (recommended)

Borg Warner's latest release, the EFR (Engineered for Racing) Series  turbochargers. EFR is currently the most advanced turbo of its type  engineered for the performance aftermarket. Crammed full of attributes  that appeal to the performance car enthusiast, EFR is at the pinnacle of  what can be done with the current state of the art.

The EFR line of turbos was born out of an internal BorgWarner Turbo  Systems program labeled Advanced Aftermarket Products or AAP.

The result is the new EFR (Engineered for Racing) line of turbos from  BorgWarner. These turbos contain a bevy of key attributes such as Gamma  Ti turbine wheels, dual ceramic ball bearing cartridges and investment  cast stainless steel turbine housings. Collectively, those features help  give the EFR line its innovative appeal and will provide a breakthrough  experience in durability, device responsiveness and installer/user  satisfaction.
