it [ethanol] has more power

Sorry to disappoint you , that simply isn't true.

An engine optimally designed to burn ethanol (usually with a turbo) can indeed
produce more horsepower on ethanol than it does running on gasoline but it does
that at the expense of burning more gallons of the ethanol.

What it does mean is that for a given power output the engine can be smaller if
you use ethanol as a fuel instead of gasoline. And that's why racers like it
since smaller = lighter = faster (or simply more horsepower from the same engine
size).
