Borg Warner EFR Series 9180 TurbochargerEFR 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)
