I've never had good luck with making serious power out of NA motors with Meth. I've found that it provides great knock reduction and raises the effective octane of gasoline, but often times, knock isn't the limiting factor for NA cars. With forced induction, where intake air temps are much higher and combustion chamber pressures are increased, it makes a big difference, but I doubt you'd make significant power on our cars.
