race fuel

:SNSign: how much of a gain would one get running race fuel & is it bad for the car?

IMO unless you tune for the use of high octane fuel you basicly are just throwing money away, and in some cases perf will actually diminish.

Being a blower car, there could be quite a few ponies to be had with a "race fuel" tune. You could run more aggressive timing with the higher octane fuel.

Just throw in xylene. High octane and cheaper than race fuel.
