i have a 01 camaro z28 with a nos plate kit, when i spray it, it shuts down for about a second or two and then pulls hard. what could this be?

any controllers hooked up causing a delay? air in the lines? Solenoids getting stuck?

teblmb

no nothings hooked up in between but a relay, i purge it first so maybe no air but i guess u never know, when i checked it with the lines unhooked everything works.

Single 43 jet? and when you hit it does it just delay before accell or does it decell (bog) than accell. what WOT and window switch?

teblmb

yes its single jet with a 30 fuel jet, its on a button and when i hit it, its like it shuts down and then kicks in hard like its supposed to. i can kick it and it pulls hard then i hit the button and its like the shut off and then picks back up after about a second, no delay just shuts down.

fueling is not right its way rich it should be like 22.

---shiz from atv's laptop .

for a 30 fuel you should have 62 nitrous.

this button, does it closed the ground on the relay? How do you have it wired?

teblmb

thanks for input, i was just going by nos's instructions, 75 shot is 41-26 so i figured a 43 and 30 was close to right. this still could be it though.

teblmb

i have it wired like the instructions say, i dont much about if closes the ground or not but it should be right. when i check it without the bottle on and the car off everything works fine. its very confusing. ill check the wiring again though just to make sure.
thanks

Nos's instructions are rich and you made the rookie mistake of rich is safe so richer is the bestest.... IT is your problem.

43=75 shot and gets a 22 jet
62=150 shot and gets a 30 jet

you have a 75 shot with 150 hp worth of fuel. all it takes is your motor tune to be in the 12.2 range and it will fall on its face. your motor tune probably leans out up top so its enough to run.

thanks for the info: i went tried a 24 and a 22, same thing happens, this sucks really bad.

Could be a sticky nitrous noid, what is your bottle pressure? If it's falling on it's face, it could be overfueling because your fuel noid is opening before your nitrous noid. Get your pressure down to around 900-950 & see if it still does it, or borrow a noid from someone to test it out.

I almost got kicked out of an event last week due to a sticky nitrous noid. I was racing in a street class that called for mufflers, I had my cutout open & went to spray, it dumped straight 114 from my nitrous cell into my motor, at the big end they were on my *** about fire coming out from under my car & almost made me leave the race for bypassing my mufflers. I just glanced at my bottle pressure before going & didn't purge it down enough, my noid was pressure locked.

Ive noticed big lean spikes will give you that 1 sec of silence then a hugh kick in the ***. Try to rig up a fuel pressure gauge and watch it when you spray. Ive even done some crappy set-ups like duct taping a gauge to the windshield temporarily just to see what it was doing. You will most likely see a drop in pressure when the noid opens, normally just a few psi. If your dropping 10psi or so, then that is a problem.
