Your a fool. You have no idea what i have used. I have used NOS (NOS and Venom), i have installed it, i have raced with it, i have raced guys that had it and thought they were the s.hit. but its really not what the "Movies" crack it up to be.
I'd be willing to bet that as soon as you saw "The Fast and the Furious" you went out and bought your first wet injection kit for your crappy "boat on wheels" (your mustang) and were ready to kill all thoes Civics and Integras that were kicking your ass on the streets. but come to find out, you still loose, cuz your car really isnt set up to truely handle NOS. So all your dreams of instant respect with the touch of a button were dashed.
Get real man, Turbo/Supercharger is the only way to go.
