Shorter life cycle involved :-)

But--tractor pullers do it pretty commonly. And--it WORKS. Spools 'em up
right quick. Probably a LOT less water in relation to mass flow than what
you are talking about. Talking about things on the order of a 430 cid I-6
running 60--65 psi boost, single stage (non-compound) turbo, 6000--6500 rpm
on the motor, no IC, running water injection downstream of the compressor
for charge air cooling.

Lots of irrelevant stuff that ain't SUPPOSED to work, or even be possible
!! But there it is. And the numbers back up what happens.
