    Home made E50 for racing?

    Just thinking about cheap alternatives to straight E85 that might work in an unmodified carb. Let's say a guy has a 11.5 to 1 compression iron headed motor and wants to get by on a budget. If a test kit was used to see the true % of ethanol a little math could be used to determine a mix that...
