Exhaust Water Injection

Hello, I've been researching into injecting water into the exhaust post turbo and the theory looks promising. However, the math to calculate how much water to inject does not seem to exist. I have scoured the web and come up with some components but they are ideal gas laws without the inclusion of water vapour and formulas for water vapour but I haven't a clue as to how to calculate the data in a meaningful graph. Is there anyone here that has the fluid/thermo dynamic skills to find an injector size @ 50psi pump pressure? I was reffered here by dust at devils own wi. He mentioned someone here may have some knowledge on this.

Thanks,

Lee.

How would that make power? On our 2 stroke jet skis we would spray water into to exhuast pipe to change the power band. But spraying water after the turbo into the exhuast I would think would not do anything
