i was looking at this system called cry-o2.it is like nos only it does not hurt your car.it brings the temp of your fuel and air really really low.it uses the same setup like nos(bottle)and you can buy purge kits for it also,the o2 sprays into your air intake and there is a fuel rail that you put on in your fule lne that chills the fuel to -80 degress.and the kit is only around 350 bucks,wnat do you guys think.and the bset part it wont hurt your engine
