noids too small. ya know, i never knew if it was the noids, or if the car was doing massive KR. but, this weekend. went out and did some dataloggin on and off bottle. changed jets, only to come to find out. no matter what jet size above a 46 {nos} it did the exact same results.
46n
24f
vs
52n
30f
max kr was 5 degrees, and settled back down after that. pulled the exact same. the 52 is "said" to be a 150 shot. sure as hell didn't pull like it!
the noids im runnin are the lil guys, the same nitrous one used for the basic purge kits.
is my thinking correct on the noid not being able to flow enough?
bottle pressure was 900 on both runs. so thats not enough of a variable

according to my charts, a 52N jet is a 100 shot. 63N is a 150 shot. then again, i don't have a v6. but, to answer your question about the solenoid being too small, i did a test comparing a .081" orifice solenoid to a larger .125 orifice solenoid. this was with a 63N jet.

Ny-trex baseline calculations at 900 psi
EFI Single Wet Nozzle
HP -- 40 psi N/F -- 45 psi N/F -- 50 psi N/F -- 60 psi N/F
50 ------- 35/21 ------ 35/20 ------ 35/18 ------ 35/16
75 ------- 41/26 ------ 41/24 ------ 41/20 ------ 41/18
100 ------ 52/31 ------ 52/28 ------ 52/26 ------ 52/24
125 ------ 57/33 ------ 57/32 ------ 57/31 ------ 57/28
150 ------ 62/36 ------ 62/35 ------ 62/34 ------ 62/32
so, the 52N/30F hits right on the 40 psi range for a 100 shot. you might be getting fuel knock. throwing too much fuel at once can cause 'knock' and call for retard. maybe back off the fuel pill and see what happens. but, you should really find out what fuel pressure the motor does have.

well, the 46/24 set up i have right now, is 12.0 all the way up on a/f sniffer {at tail pipe} i really don't see the point in going leaner then this.
maybe a 52/28 set up perhaps. i never did the a/f sniffer on the 52 jets. i may do that this weekend to see whats up with it.
so, the noids may not be too small, but could be incorrect jetting. hmmmmm.
just an fyi, the car is a 5.3 v8. not a s/c v6 car. think new imp ss, and monte ss. same motor.

i have a cat on the car. not like the 3-4 cats like a mustang or something. im aware of the cat sucking up some of the fuel on the a/f charts. which is why i jetted for it.
i have a few more things to try this weekend to see if i truely need bigger noids, or just correct jetting. we shall see

puts me right at the 52/26 area.
hmm, may step down the fuel jet to a 28 from the 30 and see how it does

lots of kr is bad, a little kr, maybe a 2 degree isn't as much as people make it out to be. but im sure i'll get a datalog of it before i go off the deep end

I have heard that a exhaust pipe bumping on the floor can some times be interpreted as knock by the PCM. I know on my car when turning in a parking lot real sharp and slow the PCM reads the noisy Dertoit locker in back and retards the spark. Couldnt beleive it when I saw it, through me off the 1st time it happened.
basically i can hit the button, let off real quick, and hit it again. the first initial hit it knocks 3 degrees, then comes back down after 200-300 rpms.
but if i hit, and let off, hit again, it doesn't do it.
dunno. it might be the initial shock of it triggering something. it knocks 2 degrees on the motor, at maybe 3k rpms. then drops suddenly. next pass, nothing. might be an exhaust thing
