I'm not trying to argue, but Gerry are you saying that water would not evaporate if sprayed directly into a cylinder? Maybe we should all start spraying our fuel 20" from the throttle body <G>? There are a few engines that spray water directly into the cylinder (take the 6 stroke water/gas engine for example). IMHO, there is no way you can keep pressurized water sprayed in a fine mist from atomizing in an engine. FWIW, I don't really view cooling/density as the reason I use WI. Excess water (water in addition to the water of reaction) helps slow the reaction/combustion and deters knock. It also keeps your engine clean of carbon deposits that could lead to predetonation. WI isn't a 2nd intercooler, it is much more complex than that.
