only using 1lb if nitrous per run..
so, I'm lost...
i have a GM cam... 239/251 .570 . .570 , 3600 stall on s ls2 gto....
I'm trapping 115mph on motor, 125mph on spray... so i have a .62n jet, which is 150 shot. now i know this ain't the best cam to spray on, bit its doin good..
when i trapped 125mph was with a nos nozzle, tried upping the shot and didn't gain anything. so came to find out that the nozzle was maxed out... so i got a dyno tune plate..
now the problem is that i only waste 1lb of nitrous per run...with the nozzle, since i haven't tried with the plate...from what i read i should be wasting about a lb and ahalf, but only wasting 1lb...
before the cam i was only gaining 12mph, now 10.....i know the cam is wasting some of it.....but why isn't it wasting like it should?

10mph increase is not a small pick-up lol
Are you running wet or dry?
Whats your concern? (i think i am missing the point here).
If I am reading this right you lost 2mph by going from nozzle to plate?
Does your afr and/ or plugs look the same between the two? I would susspect that you are running richer with the plate hence the loss in mph?
I would not worry at all about the actual consumption. I would be way more concerned with the way the vitals look (reading the plugs, AFR or EGT, consistent bottle pressure...)
Consumption could result in a ton of different factors...
Activation time of the system, shut-off point and etc will all factor how much you are using per run.
I would be more concerned with figuring out where the 2mph went vs the amount of spray your using.

you understood wrong.... i just got the plate,i haven't tried it out yet....
i guess my question should be, how much mph are you guys picking up with a 150shot on top of a cam.

Depends on who you listen to for nitrous theory. Some like to see very small and light fuel ring and some like to have no fuel ring at all.
Tune with the plugs and then look at the a/f for reference.
