water injection

has anyone heard of or seen water injection fitted to an engine. for those who dont know its where you squert water into the intake to cool down the incomming air. you can raise the compression and/or advance the timing. also the water forms steam and adds to cylinder pressure thereby increasing torque and power output, improving fuel consumption and efficiency.
i heard the McLarren F1 team were experimenting with it during the early 90's and were getting track records that remained unbroken but the f1 racing body banned it. (i could be wrong though. im not real sure)

It's used quite a bit on aircraft, both piston & jet powered.

Umm... Im not the expert on the subject or a rocket scientist but my older brothers VN ran water injection which he rigged up himself quite easily.. I dont know how effective it was but he experimented a lot with it using basic home supplies to professional performance parts. He had a CAPA stage 2 supercharger running on a vn 6 then a fully rebuilt and race spec'd vr 6 engine, kept in a sleeper blue VN S pack manual. He ran ~9 psi. He always used to be saying how hot damn blowers get or anything with forced induction.
Not sure nowadays i know a little more why he didnt run a fat front mount air-to-air cooler? I think it was about throttle response or something maybe, that car was a gun. The water cooling was a big difference tho over nothing, as the car had no scoops or light cutouts anything, just stock looking with 15" hub caps on mega yokos.
Ohwell now he has a 4 cylinder again how funnys that.. although turbo and 4 whl drive ..

Some superchargers are integrated into the manifold, so it's not possible to use intercooling. This is often the case with V6's and V8's where the best place for the blower is in the valley (not much room anywhere else).

A recent ZOOM artical about Ray Halls IS200 with a 2JZGTE uses it. He could not fit an intercooler so he uses water injection and runs 1-1.5 Bar boost without a hint of detonation. Its controlled by a top end ECU, Motec or Autronic I think.

i just descovered that some of the gas fired power stations use water injection. as well as greater efficiency and all that other stuff, it reduces the NoX levels and other crap from the emissions quite considerably. aparantly theres some "simple" mathematical equation that can prove it. mayby it could also be usefull for getting past emissions standards
