Cenpeco makes an additive for ethanol blends. I have also read that e85 is really good for high compression engines. I'm running 12.5 in my car. It burns more fuel but is rated at 105 octane. Compared to racing fuel it would be worth it. You just have to run monster jets and a high flow pump. Do a google search on it. The only reason I haven't switched over yet is there is no stations around where I live to buy it yet.
