EFR 9180 is the biggest, baddest, highest flowing turbo in the EFR family. Capable of a remarkable 94lb/min airflow and stable at very high boost levels, the 91mm OD compressor measures 67.7mm 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 700-1000hp 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)

Testing
Below is a dyno chart from the Sierra Sierra Evo, equipped with the EFR 9180, Full-Race Twinscroll Manifold, 2.2L engine, revving to 8500rpm with ~32 lbs (2 bar) of boost.


Wastegate Info: All EFR Internal Wastegated turbos come standard with a medium boost actuator for boost levels of up to 16psi. For boost applications above that will need to add the High Boost actuator. Use the option tab to add it to the order.

V-Band Discharge Flange/Clamp: All of the EFR Internal Wastegated turbos use a special BW Vband flange/Clamp that is not a standard V-Band. The Down Pipe V-Band Flange and Clamp are not included with the turbo. Use Option tab to add them to the order.
