    In brief: Water injection cools the intake charge through the latent heat absorption of water in the evaporation process. Same principal as patio misters. The water vapor absorbs the heat in the intake charge and cools it down. I have seen 30-40 degree Celsius drops on my Power FC monitoring intake temps after the huge air/air intercooler has already done its job.

    Since we know the engine is a giant air pump, and the amount of power it is capable of producing is direction proportional to he volume of cool dense air it is able to ingest, the technology behind water injection makes perfect sense. Think of it this way -- everyone is concerned about air volume:

    "How big of a turbo should I run for my power goals?â€
