From what I've read, mostly on a turbo stang forum, e85 is pretty sick for high performance cars/trucks. It is usually around 104-108 octane, so for high compression applictions its a pretty good idea. I read an article about a twin turboed 331 strocker foxbody running 30psi in each turbo pulling989hp with no missfires!!

PS Build a still then you can make your own!!!
