no one mentions the fact that you use more e85 to get the same about of energy... as gas
so you're going to use more to go the same distance, and you're going to have to spray more into your engine to get the same power.
and 85 is heavily subsidized, it actually costs more than gas. you're just making other people pay for it.
fuck e85
If I had a choice between E85, which is around 104 oct, and 104 oct leaded gasoline, I'd still probably go with E85. It will burn cooler, the extra you have to spray also helps that, and it burns cleaner with less soot. I've talked to Tony1 about it, and he generally sees ~8% power gains for the same boost level when using E85 over 93oct. You're using more fuel, but you end up with a higher power ceiling. You also can end up with better milage per dollar, since you can also use more timing. FYI using a normal engine with E85, even 10:1 CR, is like running an NA 7:1 engine with gasoline. You get a whole lot extra if you run the extra compression.
FYI The EPA considers it
illegal to modify a gasoline engine to run on E85, at least for road usage. To be legal, it must be a EPA-certified kit that gets installed. Propane injection is a whole different story, since it burns very cleanly.
