I've seen quite a few cars make nearly 10hp per lb/min on E85 (in person on a mustang dyno). If the EFR series is like the Airwerks series (which would only make sense), then they will keep making power even in the 30-40psi range. I don't see why a 6758 couldn't make 500whp in kill mode on a well modified SR, especially on a dynojet.

I think the real question is how will the 7163 perform in twin-scroll form? Changing setups is a lot easier IMO with the internal gate, and if it's like any other turbo when it comes to twin vs. single scroll, it will be by far the fastest spooling/responding 500whp turbo on the market.
