Oddly enough it has been used in production cars the most recent was one of the Saabs, and lots of research isn't currently being done into using it again as getting more power from the same amount of fuel of course means you can get the same power from less fuel and make a more economical green car.

Why isn't it used more? Well for a car it's more complicated, which means more expensive, also all current emissions standards are based on traditional ICE standards, if something doesn't comply then often its dropped rather than the legistlation changed. Audi's ProConTen system is a prime example, it was better than airbags but because legislators said airbags were a must Audi dropped it.

Also, it'd mean car drivers having to fill up with water, which would be just another hassle going out to your car with a bottle of water opening the hood and pouring it in a tank somewhere.

Anyway, I'll build one and we'll see, best thing to do is experiment, not speculate I reckon.

Could not this thoery be tested at different variants of relative humidity i.e. try at 30% humidity then wait till it rains and try again. I always notice a power decrease on hot dry days, that could be due to less H2o molecules in the chamber.
I use mini combustions most of the time so it would be easier for me to tell power increase or decrease than someone using a spray and pray behemoth.

When you fill your car with refined oil remember that it has been paid for with blood and guts, some from your own countrymen, most not.

When I was attending Wyo Tech, I had a professor that had an injection nozzle mounted on the inlet side of his banks turbocharger to inject small amounts of water to do the very same thing, but you will not have the sustained heat to make it work in a spud gun
Yea, that's definitely going to get you at least a tazer.
