my older bro had a VN v6 commowhore for a while with a supercharger bolted on and rebuilt/balanced internals... it was good for a fair bit of power with the ecu tweaked and the blower hooked up..
to cut a long story short, he hooked up a bit of water-injection into the inlet somewhere, with household items, and he said it helped keep intake temps down and stop detonation...???
anyway thats the only time ive seen it in operation in someones engine bay..
