only down fall to N2O if the fact it put alot of instant load or stress on the motor. the blowers have a constant load in a liniar fashion, N2O has what is called shock. once you hit the little button you get a huge shot of HP all at once. say you use a 250 wet kit and you dont run a ramp. you go from 400 hp to 650 in a instant thats when you start breaking. as long as you run on the fat side and you have good spark N2O is a great adder. you have to look at the cost issue, a paxton or roe system will cost about 9k with the install. if you do it your self you save about 1500. a good nx kit with all the goodies is around 2500 with out the install, now thats with the fiber bottle and purg lines along with all the electrical safties and ramp box. now its cheaper but now you have to fill the bottles all the time theres a good chunk of time because you have to drive to the shop drop off you bottle let them freeze it before they fill it. now your truck will also run rich like a pig unless you have a sct tuner or some other way of having 2 programs one for spray and one for everyday driving. ok so now that you have your bottle in and you want to run, step one change your program, open your bottle, purge your lines, oh yeah race if over because the guy with the blower had all his stuff set up and ready all he had to do is step on the throttle, oh yeah keep an eye on the bottle pressure other wise you will be down on hp half way through the race and your saftey device will shut the NX off and now you are runnin rich wasting your gas.
