i have searched and there isn't much about this topic. first off, this is all "hearsay" from the conversation i had with a buddy of mine last week. i haven't done my own investigation yet but i figured i'd throw it out here as food for thought and get some opinions of how it could or could not work for us. anyway, he was telling me about using alcohol over propane or water. he said that alcohol guards an engine against detonation much better than the alternatives and you can run much smaller injectors, thus not spending so much on gas but still maintain high octane levels. apparently he knows a couple "old style buick-turbo tuners" and they've been doing this shit for years. the best thing about it is that you can hide everything to make the engine bay look stock still. (on a buick or gst yes, obviously not with an aftermarket snail kit) the buick guys take the wiper fluid container and mod it for the alcohol setup. sounds interesting, gimme your 2 cents...chris
