Angry nitrous user Ok, I went to the track yesterday to try out my new NX kit and the nitto drag radials. To say the least I am very disapointed. My best 60' was a 2.2 on nitto drag radials, I do better on stock street tires. My best sprayed 1/4 was 13.7@103. Stock I ran 13.4@106. Now isn't nitrous supposed to make my car faster? especially a 150 shot? When I spray, I feel the difference, but it doesnt feel like an extra 150hp to the wheels to me. Now I have a check engine light and my car likes to idle at around 3000RPM! I think that the throttle position sensor went out. Guys I'm really depressed and dissapointed after the time and money I put into my car. Please help me out.

That's why it's usually not a good idea to start out with a 150 shot. I assume not, but have you tried a smaller shot? What was your bottle pressure?

a 150 shot can be felt HARD....you must ahve something wrong..check KR and timing with a computer/scanner....may have comuter pulling a ton of timing out, also check for leaks, bottle pressure, right jetting (not reversed, remember bigger is on nitrous side), trash in filter (inline filter and solenoid filter), nozzle placement, battery/ground issue....lots of things to check out.

I had some problems with my nitrous on my GTO...pretty sure it was a used timing tuner I bought, so I am getting a new one to seeif it helps...everything that is not stock will have some problems...period!

Are you sure the nitrous is coming on? You say you feel something, but your trap speed is indicating that your engine is not recieving any nitrous. Test your solenoids to make sure you didn't get a defective one. And you NEED to log some runs, see where your a/f ratio is at (maybe it's only spraying fuel).

check the noids with the n20 off and you should here a click from both of them. Start with a 75 shot and work up. Also 4 me a nitto has to be smoked for around 10 seconds and start with 18psi air and go down from there if needed.

One good backfire into a plastic intake full of wet mix,
and you'll have a hell of a vacuum leak, and count
yourself lucky if that's the worst of it. Not that lucky,
if you cracked the plastic. But better than holing a
piston. Time for you to unplug the IAC and start
shooting propane (unlit) all around the intake and
see if you find a hole by the idle note. Maybe you'll
be lucky and just find the MAP sensor blown out of its
grommet. Getting the code read would help you.
Spraying out of the hole makes some sense if you
have super traction. But if you can spin the Nittos
without N2O then why bother with spraying in 1st
gear? Just a waste of rubber.

Ok this is not right for sure. Things to check. 1 Bottle pressure, and bottle on. 2. Simple dry fire with the nozzle removed from the boot (hold tightly). 3. Check the jetting. 4. Make sure the nozzle is aimed at the intake not the maf sensor. 5. Check the jets, make sure there is no trash in a jet.
If all checks out. put the 75 or 100 shot in to start. With good plugs, and the system working, 100 should set up back real nicely. Once that is done then go to the 150hp. Check it all out, and you need to talk to a tech call me.

yeah, what they all said, also, I got rid of my nitto's because my traction really sucked with them. I moved over to M/T ET Streets and got my 60' down to 1.77 shooting out of the hole (with a 5200 lbs truck).

well first off why are you going to spray when you KNOW theres problems with your car.Thats just asking for further problems. First off get your idle problem fixed. What plugs are you running? Need to do TR6 gapped at .35-.40. Are your jets the right ones? Call NX and make sure you have the right ones. Why do you have an SES light you need to get that checked too. What you could do you make sure everything is right is pull the nozzle out of the bellow and hold it up and have someone push the gas pedal to make sure its spraying the right way at wot.

The idle problem happened during the nitrous run. I'm going to have the car scanned ASAP, I know the nitrous was spraying, I could feel it when i hit the arm button on the run where i sprayed from 2nd gear and on. It didn't hit very hard though, I would imagine 150whp would feel a little stronger. Right now I just want to get my car running correctly. The idle goes over 3000RMP and stays there for a while and comes back down but is never stable and it repeats. bottle pressure was around 1000-1050psi. Also SES light came on and stayed on after spraying. Resetting the cpu would get rid of the light but only to come back after spraying again. I will check my A/F ratio soon although i think it is fine. I didnt know nitrous could be such a hassle. I wish one of you guys lived in the south florida area.

I had a really bad idle problem recently, sounds like what yours is doing, but it was throttle body related. Where exactly is your nozzle located, maybe post up some pics of your install?

Did you put colder plugs in? was everything hooked up correctly? did you take the shrader valve out of the fuel rail? sounds like your having some serious issues double check the jets also make sure you put the fuel in the right spot and the nitrous in the right spot.

I dont know about cooking pistons, the car runs fine as long as the engine is in gear and under load. no weird noises or anything. The engines just likes to idle at insane rpms when the clutch is depressed or you drive in neutral.
