Lower IAT and cooler combustion, 2 things that are conducive to power production in a boosted combo. E85 is a great fuel for boost, far more dramatic than the gains in an NA combo. I have zero experience with nitrous and E85, but wonder how it would work. Back in the old 5.0 vs Turbo Buick days, I was on the Buick side of things and have been a boost guy for decades. The other side loved nitrous, we all learned a lot from the rivalry there. Before I derail the thread, I'll go back to the original topic. I could be wrong, but I don't feel like there's going to be much gain over race fuel in this case.
