Is this a guess, or is there something you can show? And you do realize that exhaust gas has water vapor in it, right?
Assuming that you mean to flood the intake manifold with steam, then yes, pumping losses do approach zero. However, that's because you're diluting the intake charge with an inert gas (water vapor), thereby forcing the throttle to open up to maintain the same oxygen intake, not because of any magical properties of water becoming steam inside a combustion chamber.

In order,
In order, pressure of steam at 100c is 1.0142 bar. which is interesting if the rest of the "atmosphere" is not at one bar.
More interesting is what is the pressure of steam at 400c? I can't find the answer.
it is indeed a guess as a place to start based on an old timer I met who did this in the 70's.
Pumping losses are significant. 10 to 15 percent. So if nothing else, we have magically found 10 to 15 percent possible gains.
