I gained over 20rwhp and 10rwtq switching. I have a 12.3:1 motor with e85 we could get more aggressive with the tune and gained some power. E85 can support an engine thats 13-13.5:1 so imagine gaining the 15-25 horse with compression on top of that. if the setup is based around it its actually probably the biggest bang for your buck vs $10 a gallon race fuel.

not only did I see a power gain, I dropped 15* engine temperature.

and as far as highway milage for example my OLD 355 engine would only get 18mpg on the highway with 93 octane pump fuel. Now with my 383 on e85 I get 16mpg, and worse ive seen is 14 on the highway (depending on the weather)

Only thing Ive ran into is that E85 tends to like a little bit more timing pulled with nitrous then 93 pump gas.

If I were to just have a heads and cam stock shortblock car I wouldnt be running it. But given what I have I wouldnt do it anyother way.
