I was expecting more negative comments. My machinist says he's running 13.5:1 (not a Pontiac engine) using E85 and loves it! He says it really helps keep his engine cool. All options are being considered at this point. Thanks for the feedback - both ways. Are there any good reasons NOT to use it? I don't mind changing out the fuel lines and fuel pump. I know the carb will cost me some to get it built correctly to run on the E85, but in the long run it might be a good option. Yes, I know the mix varies throughout the seasons, anywhere from about 70 to 85% ethanol. I will need to deal with that, and test the fuel content as the seasons change.
Gus68, nice video, and it does sound good, but that's only at no load. Detonation is much more prevalent under load with a hot engine. Do you have the engine in the car now? Any issues with detonation or pre-ignition?
