Transition mixture screws

Yes, WATER will reduce the temperature, depending on how it's introduced.

Water injection involves spraying some water into the intake. Usually it is done as a very fine mist and far enough upstream so that it can evaporate. The physics behind theh evaporation process tell you that it loses a LOT of heat in the process, that cools the mixture.

However, if you have raw (unevaporated) water that gets into the cylinder, the temperatures there will change it to steam. Steam tries to occupy 1200 times the volume of water. Since there is only so much volume available in the cylinder, the pressure goes up, WAY UP. That is what bent your buddy's rod.

Indeed. Hydraulic lock is a harsh mistress. I was more wondering how water in the combustion chamber would hole a valve like a laser. I wasn't terribly clear in my post, I was talking about piston holes when I was thinking about valve holes.
