Do a google search on h20 injection, and you'll find plenty of technical
info. Basically, it isn't as if you are turning a garden hose on; the water
is injected as a fine mist which vaporizes to steam in the combustion
process. The conversion from a liquid to a gas absorbs a lot of heat (
there is some law in physics that explains this -- don't remember what it is
offhand, and this results in a cooling of combustion process, allowing more
boost and/or ignition timing.
In doing the research, one of the tidbits that stuck with me was that the
amount of water injected was still only a fraction of the moisture change
your engine sees from a dry day to a humid day.

Subject: [s-cars] RE: Water Injection.
I'm not as mechanically savvy as some of the other listers here, but by
injecting water INTO the air through the intercooler, wouldn't that change
the compression in the engine? This seems too good to be true, no?
Also, on the new WRX STi, the injection is in FRONT of the intercooler, is
it not? Would this not be a safer method of achieving similar results?
Thanks to anyone who can help the layman here....
