Flex Fuel (51-83%)
Ethanol - Grain Alcohol (AKA Everclear 95% alcohol, 5% Water?) (or make your own! MOONSHINE 100% Ethanol)
about 15.5 gallons of Everclear to 2.5 gallons of gas will get you in the range of 75 to 90 % Ethanol (assuming my calculations are correct.)
I think racing alcohol is still Methanol - Wood alcohol (supposedly nasty stuff to humans through casual contact)
I would expect your EFI to adjust the spray time for O2 output?
So if you had spray nozzles that could deliver the 2-3X the volume needed of gas nozzles it should self adjust for the 50 to 80 variation in E85
I only know any of this from having a "Variable" fuel car from the early 90s. it was supposed to run on 100% gasoline to 100% M85 as in Methanol or any mix in between (it was part of an experimental fleet of cars in So Cal) it had special injectors, fuel pump and controller.
