Solenoid going bad? i have a 90mm N.O plate, been running a 74n/35f jets fine for 3 months through a NOS 16000 cheater noid. (Noid i bought used about a year ago) i've been increasing the shot in small increments from a 125 shot to where i am now, everything was running fine, good 12.2 afr's on the 74n jet. So the other day i decided to try a 76n with no other changes (watching my afr's real closely) and the car actually ran richer and slower obviously, afr's were in the 11.2ish through the hit, tried it again and same thing, so i said screw it and put back the 74n jet, went for a test drive and at first afr's were 11.3 then slowly climbed to 12.1-12.2 through the end of the run.. So i was thinking maybe its time to replace the cheater noid?.. anyone?
4an line? if so thats ur problem . sometimes plates dont flow well after 150. i seen the same kit as urs on a 2010 camaro with a 200 shot make no more then it did with a 150 jet. put a nozzle on it and it picked right up.

What was your bottle pressure? Do you have a nitrous filter installed?
You only went up 2 jet sizes which isn't much is the reason I'm asking those 2 questions because there might be something restricting nitrous flow or pressure was down. A 76n jet will be fine on a 4 an line, unless the line is 25 feet long or something.

Being that that solenoid is 200hp, its probably somewhere around a .078 orifice... just off the top of my head, and if you are running a 76 jet in it, it might be close to maxing out that solenoid, which should be around 200 HP as stated, but you are only running a 125 shot? What fuel pressure is that jetting for?? According to my jetting, a 76 would be right around 200 HP worth of nitrous through that solenoid...
Thanks.

Thanks.

The 16000 is the Cheater solenoid and has an advertised orifice of .093. The -4 Main feed line is fine at your power levels so I cant see that being the issue. What does the fuel system in the car consist of?

I tested the car again after replacing one of the plug wires that was kissing the LTH's and everything seems to be back to normal.
