Another thought has crossed my mind.
First things first, I have never run E85 and am operating on many assumptions here.
My understanding is that the primary reason for switching to E85 is to avoid pre-ignition (spark knock).
What I'm unclear on is if E85 will make more power than gas on the same boost level and good tuning, and whether there is a line that can be crossed where even the E85 will self ignite.
I am thinking about this because it would seem logical (if E85 won't suffer from pre-ignition) that one would be able to build a high compression motor (like 11 or 12:1) and then throw 15-16 psi on top of that and really make good power. This would increase the off boost power curve, should increase the off boost fuel efficiency, and would alleviate alot of lag associated with big turbos. But I don't know enough about E85 to know if this is even possible.
