Change the compression ratio which adds more air to the combustion process allowing the lower energy, but higher octane alcohol to produce more power.

Changing compression ratio does not change the amount of air that a naturally aspirated engine can draw in.

Alcohol engines do not produce more power because they run at a higher compression. They produce more power because more fuel gets into the cylinder. Lower energy fuel is put in quantity greater, 2.45 times more fuel, enough greater volume of fuel that more power is produced.
