The water might be better used externally on the intercooler. Evaporation would dramatically increase intercooler efficiency.

The water can also cool the intercooler internally, and transfer the heat to the engine. It doesn't have to be used on the outside of the intercooler.
Although I'm not 100% sure if the water droplets would vaporize easier in the hot intercooler, since they're under pressure, and we know that for every bar on pressure, water boiling point goes up by almost 10 degrees.
As far as piston blow by gasses, engine oil is often run at temps that would evaporate the water easily. Oil and water don't mix, and water vapor will be floating in the air pockets in the engine. Not sure how much engine oil will trap water, how much water will sink to the bottom on a turned off (cool) engine, and how much gets sucked back in the lifters via the oil pump when starting.
If too much water enters the car, it might seize.
Then again, many cars ran Chevron's over-ethanolized fuel, which attracted so much water that every time you started from a stop, so much water would come out of the tail pipe, that you could water plants and flowers with it!
