Water injection produces no steam. It fully evaporates before entering the combustion chamber.

if you wanna do that, then put an oil drip in your pipe.....Or a bleach sprayer above your tires.

create an obserd amount of smoke on demand. i was hoping for something to spray into the intake, like tranny fluid for example, that would smoke, and maybe even blow out carbon. just for the heck of it. i like to turn heads
