I've heard a different explaination as to the benefits of water injection . . . The transformation of liquid water to vapor absorbs a considerable amount of heat energy. When water is sprayed into the compressed air/fuel mixture in the cylinder, the charge is cooled which in turn reduces the cylinder pressure. Therefore, higher compression ratios can be run without the risk of detonation. In forced induction systems, one can run at higher induction pressures (jam more air into the cylinder) because the cooling effect acts like an intercooler. More air means more oxygen. More oxygen means you can add more fuel which translates into more power.
