I'm watching this with interest ... I think this sort of build would be pretty interesting around here given the availability of E85 around here. 105 octane should keep the ping at bay. Larger injectors and a new ECU map will be needed for sure (need 28% more fuel volume). New fuel lines may also be a good idea, although I have seen some reports of people running some mixes of E85 and gasoline on non-flex-fuel vehicles, and in any case everything in MN has been E10 for years now anyway and that hasn't caused any problems (for me anyway ... knock on wood).ollie said:Yikes 12.6:1!
Hope you don't have problems with ping.I absolutely have to run 93oct on my 12:1...
