The forum that focuses on quality technical information about ethanol and E85, and converting conventional and performance cars to run on E85.

Ethanol is one of the best fuels available for internal combustion engines. The first spark ignition engines were designed to run on it, and it only lost out to gasoline because of prohibition which shut down most production, and the fact that at that time, gasoline was literally a waste product looking for a market and was dirt cheap. If you have a conventional car you want to convert to use E85, or a FFV and you want to understand the characteristics of E85, and tuning methods to use with E85 and ethanol, and how to tune performance applications for racing with E85, this is the place you want to be.

We are an open form, that does not limit its coverage to only a single brand and model car or specific tuning solution. We believe there is strength in sharing information across car models and applications.

Regardless if you are using a carburetor in a classic muscle car, mechanical fuel injection setup on a race car, a turbocharged or blown performance car, or a street car with an EFI system like a mega squirt, a reflashed factory ECU or a high end racing engine management unit, you are likely to find useful information here that will help you understand how ethanol is different from gasoline, and how to take advantage of those differences.

If you are building or rebuilding an engine and want to make changes to optimize your engine build to make full use of E85 and its high effective octane in street or racing applications, we have information you can use and people who have already tested various setups who can help point the way.

Alcohols have been high performance fuels for decades, from the early years of racing when fuel blends were unlimited, to special applications like U.S. Navy torpedoes, fuels like methanol and ethanol have always been among the best available choices to fuel internal combustion engines.

E85 is rapidly being recognized as the best dollar value performance fuel on the market. E85 direct from the pump, will outperform high cost racing gasoline that sells for over 3 times as much.

If you are looking for knowledgeable people that have actually used E85 this is your forum.
