Water injection indirectly creates power by removing heat from the combustion chamber via steam vaporization. This lowering of the cylinder temperature raises the detonation threshold which allows the engine tuner to make more power by 1) leaning out the air/fuel mixture 2) advancing the timing 3) raising the boost 4) use lower octane fuel to make the same power as an engine on high-octane fuel without water injection. Raising the boost yields, by far, the biggest power gains which is why water injection is used primarily on forced induction engines.

While your grasp of physics and their theoretical application is exemplary for a 17 year old, you still fail hardcore at many practical apects of engine design and tuning.

Well You quote what water injection does now. Water injection is only a indirect power adder as of now but if you used it as a cooling system and got rid of the radiator like I said. You could take advantage of all the things you mention as well as increased pressure from the added mass! also a decrease in weight due to no radiators.
