take any old engine on a hot summer day, and run it on gasoline. Lets say it makes 100 horsepower.

Now we take the carb off, hog out the main jet, and run a LOT of alky through it. The engine can make a LOT more horsepower.

Why?

Alcohol has a much higher latent heat of vaporization, and it burns at a MUCH higher fuel rate then does gasoline.

What this means is if you pour a lot of alcohol at the engine, the alky supercools the air, letting a denser air charge into the engine. In addition, you pour even more alky, and you get more air.

Further, alky has oxygen contained in it (why they use alky to replace MBTI) because it "oxygenates" the fuel.

Add it all up, and if you are willing to burn LOTS of it, you get more power.
