lol, thats funny cuz u still got it wrong..........
its not naws, or nos like nostradamus, its N. O. S.
like an oh ese
lol
alright, now i'm sure that you know how nitrous works, but a dry shot tricks the computer into sending more fuel to match the nitrous thats being sprayed into the intake........ now if a fuel injector is cloged, or just running slow, or the fuel pump isn't giving enough pressure to give exactly enough fuel to match the nitrous, you get detonation. to run a safe dry shot, u have to replace everything from the fuel pump, fuel lines to injectors. and even then, u hope for the best.
Where as with a wet shot, the nitrous is already mixed with fuel, so regardless if your injectors are cloged, or running slowly, u wont get detonation. because the nitrous already has all the fuel it needs to be safe to u'r engine. this also makes the nitrous alot more eficent, because if you are running a dry shot, and you dont replace all your injectors, pump and lines, u'r making the stock stuff run overtime. so even if u'r injectors are clean, there not gonna run perfect when u'r making them go double time. so u'r injectors are gonna spray more and less fuel (not by much) but its enough to make the nitrous/fuel mixture a varble instead of a constant. and that will effect your hp gain.
thats y to run shots like 125hp, and 200hp and up, direct port injection is used. and if you look at this graph...

u'll see that direct port is just a more defined wet shot. because when u get into that much nitrous, you have to have extremly high efficency, cuz a lil extra nitrous on a 50 shot, u might get away with for a while, but not on a 250 shot.
i hope that makes sense....
