yes, alcohol needs more to make the same power, BUT, it runs cooler, burns cleaner, and has the higher octane. therefore alcohol can make much more power than gasoline, but you just have to throw a lot of it in the combustion. go to a dragstrip sometime. everyone with the fast cars are running methanol. we ran it in our s/c dragster and it was very nice to have and pretty cheap at that time. about $2/gal iirc.
