Yep, that's methanol. Really have to be fat with it, then the A/F ratio isn't really that accurate with it, and the plugs are hard to read besides!!!!! Used to race with methanol, it's tricky to get the mixture correct, but works great once you get things set!!!!!

On the drag cars, our air fuel is between 12.5 to 13.5 to 1. Plug reading are superb, good power, and for whatever reason the cars seem to be far less susceptible to performance changes based on weather changes???? Maybe one of these scientific guys can tell us all why that is!!!!!
