Borg Warner EFR Series Turbos - Any experiences yet?
OK, so are any of you out there…secretly busy with an EFR install? (….perhaps you have completed it already?)
They look so darn impressive on paper, I can’t figure out why we haven't seen/read of any P car builds with them yet!
What about a big hp 930 build with an EFR7670 twin scroll?
or
Imagine the potential of a 930 install (boosting only 1.0-1.2 bar), if one was to combine the sweet efficiency of the K27 compressor wheel with the low inertia and efficiency of the EFR turbine wheels.
Am I the only one, having dreams of a hybrid EFR, with either K27/K27HF/K27HFS compressor wheels & 64mm Gamma Ti turbine+twin scroll housing?

A stock 930 is far better than an incomplete project car!
