Just as the subject says, has anyone tried it? If so, how much did you gain over regular methanol? Did you have to jet the carburetor up, or was the fuel mixture close to the same?

Jet it up 4-8 sizes and see what happens. Then lean it back out for mph if it doesn hurt a plug on the 1st run. Sometiems, m5 likes 1-2 degrees MORE timing, but the fuel has to be right, or youll burn that beech up

as far as et gain, if the converter is tight, it will pick up alot more than if its loose.
