There are many differant storys going around about nitrous, i was caught spraying on a public road and they pulled me over took pics of the bottle and under hood and stuff (i don't know why to this day) nothing came out of it but a illegal use of unsafe equipment ticket which is the same as a Fix it ticket 35 bucks. then they got me for the rest of the stuff that is "wrong" with my car. The only thing is you can't have over 20 or 25pds in the car or you have to have a hazmat license to legally carry it, you can have the line hooked up just as long as you can prove the line is not pressureized there should not be a problem.

As far as spraying i never got a chance to spray it with the turbo on the car (didn't run long enough) but i wish i had, this summer i will with the T67 and a 100 shot.
