There are some inaccuracies posted so far.
Methanol burns slightly faster than gas. I run 34 degrees timing on alky, a lot of 440-1 motors on gas run more.
Methanol has more energy than gas based on a stoiciometric mixture, because it runs at least 2.2 times the volume of fuel per cfm of air than gas.
The fact that some claim gas makes more power may well be that only very high rpms allow this? The statement flys in the face of thousands of racers seeing reduced ETs going to methanol.
Methanol lowers charge temp considerably, increasing the amount of air (measured as mass) inhaled
