By the way, I think you'll find todays race gas will make more power at that compression than alky.
Really?
A particular blend of gasoline can have 40 different hydrocarbons blended. There is no way to tell what exactly constitutes the gasoline (or chemical composition) you are running.
If you look at ERC Racing Fuels specifications you will note under the line that says "Heat Release per unit weight (bomb calorimeter)" their racing fuel ranges from 18,400 to 20,100. That is btu's per pound of fuel. Using the higher number and flipping it over so that we can equate, 1,367 btu's per pound of air.
No other race fuel manufacturer provides that information, despite the fact that is the true provider of horsepower.
Methanol is at 9,770. Because the stochiometric ratio for methanol is 6.4:1 you run more than twice as much methanol as gasoline. The equivalent heat release for methanol is 1,527 btu's per pound of air.
Racing gas would have to be 23,000 btu's per pound to equal Methanol. None of the constituents of gasoline comes close. Pentane at 21,706 is the highest, most are in the 19,000 range.
That's why there are different classes for gas and fuel.
