I'm not sure I completely agree with this, but I know it'll take me too long to find the supporting documntation, so I'll let it go. However, in the case of a Turbine, injecting water does definitely increase power output, all other things being equal (compression, fuel, etc. ) The reason is that you want to extract as much heat as possible from the engine before it gasses hit the tail pipe. By vaporizing the water you cool the exhaust and the expanding steam helps drive the turbine section. I'd think that the same principle applies to internal combustion engines, too. Any heat that can be converted into expanding gasses will help push the piston. Heat in the tailpipe is wasted energy, at least once it gets past any turbocharging components (but I said I wasn't going to argue this point, so I'll shut up here.)
