...of course, at 180psi, it takes a whole lot more heat to boil water.

DUH...
Here I go acting like the inside of your engine is operating at STP....

HEAT THE WATER BEFORE!
It will actually help the combustion process since it will give more oomph to the intake (aka WAI).
I plan on doing this in the very near future, and I am convinced it works, but the water has to be heated (I will wrap it around the exhaust manifold).

Oh, not only that, but it will also keep your engine (intake, piston chamber, and exhaust) extremely clean so there will be very little drop in milage as the car gets older...

Doesn't the WAI work because it increases the throttle opening you need to get the same amount of air into the cylinder reducing your intake manifold vacuum? Warming the air after it enters the intake manifold wouldn't give you that benefit would it?

It would, you have to open the intake more because there is essentially less power (less fuel in the piston chamber because the air is expanded more). So it would not matter where the air is heated.
However, it shouldn't even matter in this case because you want to inject the water at least 6" BEFORE the throttle body in order for it to be able to completely mix with the air.

It has to matter where it is heated, if it didn't matter then none of us would need WAI because a hot engine has a pretty steamy intake manifold and combustion chambers as it is.
