oh and i should add. my buddy has a 2.2 ecotec cavi with a 100 shot of spray on it, we raced, my car with bottle against his car with bottle, same shot.....i tapped the button one time in second gear to make sure i could pull away from him, but after that, his car + bottle couldnt catch me and like i said i didnt bottle all the way through (he's my buddy i didnt wanna make him look bad either) and then later we were on the freeway from a 60 roll we both sprayed and i pulled 5+ cars on him before we got to 90. accelleration with nitrous is just insane, i couldnt tell you how he was running his system, but i was running right on the edge of red so im sure i was getting a great HP gain from my bottle, pressure is everything when you talk about nitrous systems..
