I think CO2 would be a little more effective, but it is a more costly set up and to refill. I just ran mine at the dragstrip last night. All I have done to it is K & N drop ins the sprayer and a water vapor injector (both which kick on only under boost). I ran a best time of 12.65 at 110 mph. See my time slips on dragtimes.com as of now, I am the fastest SRT. Before the sprayer and vapor injector my best time was 13.2 at 105 mph. Pictures are coming.
