Properly atomized (the more and the finer the better) water in the exhaust
manifold will increase the backpressure. This increase backpressure is what
will spool the turbine faster--just as a smaller nozzle will. The TRICK is
in learning just HOW MUCH water is needed so as to spool the turbine faster
without creating TOO MUCH additional backpressure.

You've answered you own question here !!
