For a drag race deal, that you just run at the track, its a very economical way to go. It works great with forced induction set ups. For it to be even worth using for a street car, you should run 13+:1 compression. Thats the whole point of it. Its a cheap high octane fuel, that allows high compression. If you use it on your 10:1 engine, it will pick up some power, 10hp, 10ft/lbs, if its tuned well, but isn;t worth the hassle. 3 points of compression, on a stout 10:1 steet engine, your talking a pretty healthy bit of power, and is worth the hassle for a limited use deal. Even daily driver stuff like your new Ford truck, that can run on either E-85, or gas, most never use E-85, because it gets shytty mileage, plus, its WAY worse for the environment than gas, for many reasons, none of which is the improved emmisions.

Another fuel I like, and its NOT a dry fuel, what ever that means, is the above mentioned low lead av gas. I have been using and recomending that stuff for 20 plus years. Its been consistant the whole time. Its technicaly not street legal, but, neither is race gas. Its another cheap way to go for good fuel. it will support a lot of compression. I have ran it on 13:1 iron head bbc's, and it made more power than 110 octane race fuel. The main reason its not street legal, is because it still has lead in it, which by default, makes it NOT a dry fuel. Lead is a lubricant, a detonation supressor, and it cushions valve seats, so, it is not a dry fuel like I hear A LOT. E-85 on the other hand, if anything is a dry fuel, that is. It acts like methanol, which, could be considered dry. Thats why you use an upper cylinder lube with either E-85 or methanol.

Is it not a little high 13+:1 compression with forced induction on e-85? Or did you mean 13+:1compression NA engines?
