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:dunno:
