n20 PROBLEMS -HELP!!!
Im running the tnt 100 shot on my 2002 z06
I sprayed it 2 nights ago and the car ran like sh*t, felt slower than all motor(which is stock besides a vortex airbox) , so i figuerd maybe im running out of juice, so i took the bottle out and it had about 2 pounds of juice left and the bottle pressure was 800psi. so i just assumed it was getting fuel and no juice..
WEll yesterday i went and had the bottle filled up, let the pressure go to 900 psi and sprayed it again, the car hits for a second and then ran like Crap , my question is:
1. do you think i might have a short somewhere ?
2. is my tps going bad?
3. is there a soleniod issue?
its not like surging on or off , it just hits for split sec and then feels less than all motor ,,rpms climb slow (you really feel it in the top gears like 3rd ..)
im thinking it might be the something wrong with the solenoid or TPS ..
please help!! i know you guys know your stuff.

Since the car feels slower on the bottle than it does on motor , it sounds like only fuel side is working. That means the problem isn't the TPS. You should ckeck the wiring to the N2O solenoid. If all of the wires and connection are fine then it might be the actual solenoid. Do you have a relay for the solenoids? If you don't , you really should put one in. If all of that checks out then the problem might be a clogged N2O filter. Just be glad that this problem wasn't with fuel side of your set-up or you have a much bigger problem on your hands.

Hey Butcher, thanks for the insight,
i just pulled the n20 line from the solenoid (the part right before the plenium) i hit the gas pedal and the line shot a quick shot of juice and then nothing, so i let go the gas and hit the pedal gain and then it shot out again a quick shot of juice and shut off,, so where do i stand??
the nitrous is coming on for a split sec and then shuts off.. is it the relay switch ..tps... any insight would really help me

Your system is a wet system , isn't it? What does the fuel solenoid do? Can you hear the N2O solenoid click open and then click closed without letting up on the gas pedal? How is your system wired? Does the power run from the TPS to a relay and then to both solenoids? Before you try to figure out if there is some kind of electrical problem , does your system have a nitrous filter? If so , did you check it?

Your n2o solenoid may be in need of a rebuild/cleaning. You did not state if you had a n2o filter, if not the noid can get clogged up. Or filter is dirty/full. Or a relay not doing it's job, if no relay, problem could be resistance from to small gage wire and heat. Let us know what you find out, good luck. Oh yea, solenoid can fail from heat/resistance also, depending on where it's mounted.

I have the tnt wet kit.
um I did not see a "filter" ,, just a relay switch and the tps connects to the realy switch and then to the solenoids,
it late right now but tomorrow , i will try to see if can hear anything...
lets see, i think the realy has gone bad or is shorting out for some reason... maybe not enough amps,,ill try to get a hold of the guy that installed the kit...
lets see,

The filter is that aluminum cylinder , with the blue fittings , next to the bottle brackets. It's a pretty big filter , so unless you've run a TON of nitrous through it , it's probably not clogged. I'll assume that the installer did what most people do. He joined the power wires from both solenoids together and attached them to the relay , then joined the ground wires from both solenoids and ran them to a common ground. If that's the case , and the fuel solenoid is working as it's supposed to , then the problem has to be in the nitrous solenoid. There is either debris in the solenoid or it's just failing. If both solenoids are connected to the same relay , TPS and ground , but only one works , the problem has to be in the one that doesn't work.

I would have to agree with the above. sounds like a solenoid issue. To verify you can bypass the TPS and hook it to a button with 12v. This will allow you to test the solenoids without using the tps. I hate the tps because it runs off voltage. If the switch is not set up correctly it will not work 100%. I prefer a WOT switch under the gas pedal.

well ill find out tomorrow morning, the guy that put it together is working tuesday morning,,
I spoke with TNt rep, he said sound like a connection, or TPS,, i dont think its the , tps , i should get to the bottom of this tomorrow,
thanks guys for all the input

Well we took apart the solenoid and the filter was pretty much filled with this plastic crap) i had a leeky bottle ,, the o-ring must have broken apart and go stuck in the filter.
BUt that still did not solve our problem as the n20 was still shutting off after a sec.. we regrounded the wires and reuned the TPS,, and then it came on .
So i went for a drive and the car still ran lik e crap!!!! i removed the bottle opener to run the line straight to the bottle , just for a test and when i did that, there was a pieces of plastic (again the o-ring) was pretty much the size of the hole, i was in shock to see that size of a plastic, it was huge.
well i decided to still run the car without the bottle opener
the bottle only had 650 psi, but the car hit like a mother- so we are back in business, tomorrow ill try the bottle opener again,,
so everyone was pretty much right, clogged solenoid, wireing , tps...
thanks guys!!
