Rep Power: 757

ok, i just set up my nx 150 wet shot. so i decided to go on a test run, and when i did, i hit the nitrous at a lil over 3grand and the sucker caused my car to knock or something. i think its runing lean because its on a stock fuel system. should i get a 255lb fuel pump and new injectors? i want to run the nitrous without having ne more problems. so ne other suggestions on what else 2 buy would be great, cause i dont wanna **** ne thing else up.

that's a bit much for stock fuel system, also you may need to bump up the octane, if it knocks still you may have broken something

LoL please don't tell me your running a button as a nitrous switch.

I'll 2nd that. I hope your running a window switch or something.....right? Are you spraying though your shifts?

I didn't even pay attention to that good catch

i have a arming switch and then a throttle switch. i hit the nitrous at about 3 grand and i have even hit it long enoughwhere i would have 2 shift. and ne ways, i have an auto so i pretty much dont have a choice about spraying thro gears, cause if i let of the throttle it wont shift as u guys should aready know.

is it knocking with the nitrous off? if so something broke, if not then you were experiencing detonation (you are running premium with that aren't you?)

it knocks now without the nitrous. i think now i might have broke the tranny mount or something, most likely from torqueing it. and yes im running premium.

def. upgrade your fuel pump. I upgraded mine for a 100 shot on my v6.

ok i have a 94 gt and i run 75 tops of mine with a stock fuel pump.

once u get to 100 shot or more you need a bigger fuel pump with a fuel pressure regulator to pump the psi in the fuel up.

with my stock pump i have my fuel already up 5 psi more then stock

and about ur gas i hope u are running 92 gas in that thing with colder plugs
