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)
