I was autocrossing a couple of weekends ago and there was a 911 running a "redneck engineering" water injection system. It consisted of a small pressurized bottle of h20 and a hose running to the motor, he would pump the bottle up and open a valve right before his runs...he claimed it helped HP.... He got 2nd over all that day. less then a second behind a shifter cart! What does this do i am just curious i had never seen anything like that.

 

aquamist comes to mind:

CARX7 is running the aquamist system. He would be a good person to consult.
