The alcohol is only added to the water to prevent freezing
at low temp/high altitude.

The water is injected instead of a richer mixture to allow best power fuel mixture.

The water inhibits engine destroying detonation, allowing use of more manifold pressure (supercharge), the increased manifold pressure enables the engine to produce significantly more power for a limited time period.

In wartime water and alcoholmixture also was injected in pilots to prevent freezing.( the water was added due to shortage of alcohol).

Previous post did not seem to understand the technical side of water alchol injection and how it greatly increased power.

The alcohol also adds more energy into the combustion chambers. With the evaporating water cooling the mixture, the volume increase for a given rise in temperature is significantly larger.

My favorite water-alcohol-injection mixture is 60/40 - VODKA

CHEEEEEERS!
