Ok so realistically what kinda of power should I expect on a 200hit with a nitrous cam? I have alot of learning to do because I thought this setup would easily break 500rwhp
Even with a nitrous specific cam. Would I not be better off with a cam that makes 540na and spray then one that's barely making 470na (sae)... I still believe their maybe another reason other than the cam.. I'm going to try a few more things and see what it traps.

Started putting some tsp 1 7/8 headers on with a tsp y-pipe with 3inch in/ 4 inch out merger. I just realized that there wad about 3ft of stock intermidiate pipe under there right after the y. So all that will be changed out and ill have updated results soon.

Back from the dead! Went to the dyno today, temps were 30degrees cooler swapped from 1 3/4 headers to 1 7/8 with a better merger y and it made 524/472 now here it goes getting weird again every shot of nitrous I sprayed was atleast 50hp off. The bottle was filled but freezing cold had Teribble pressure and I think it was spinning some on the rollers.. Hopeful someone can chime in on my graphs, they look horrible. It's a nitrous outlet 102 plate.. Everything is set up somewhat for the nitrous... Just is not hitting hard.
Was running pretty rich also
Na 524/472
100shot 566/501
200shot 661/593 78n 46f also tried 44f didn't change much
250 shot 641/ 585??? 88n 46f

200 shot, full bottle but no psi maybe 600
Why so wavy? bottle pressure or tire spin? it sounded like it was being pedaled in an out of the throttle

Idk bottle pressure because my gauge just happened to break earlier but when i first hooked it up it was showing 550-600, but it had just been filled... The air fuel was on the rich side to me... I think in the 11s, I don't see why mid 12s would be bad.. also timming was at 19 Im thinking it may like 22, but im no professional.. I paid to have it done and they didn't seem to cornered! said I probably need a higher flowing valve for my bottle.

I agree, even though the bottle was full, it still needs some psi correct? I mean isn't that what nano and bottle warmers are for? I normally would heat mine till 1050psi at the track. This bottle was in the freezer for over an hr for the fill then put straight on the car. I wanted to heat it up some but the tuner didn't seem to think it was necessary.. ANybody have any ideas why my graph looks so crazy and falls off so hard?

With some more tuning and dialing-in of the nitrous issue, you will be making killer nitrous numbers. How are you going to hook those monstor nitrous numbers?

Your tuner is an idiot if he didn't think bottle pressure was an issue. That's one of the most important elements of nitrous tuning. Everything in a nitrous tune revolves around bottle pressure. It needs to be dead nuts consistent to tune properly.
PS Put a jumper wire across the hobbs switch and run it. Betcha it cures it.

well if you have timing pulled for a 250 shot and still making 520 hp then your making awsome power.
I would really be concerned with my tuner here, seems like maybe alot of your issues are comming from him.
lets hope he actually is pulling the timing back for your n20

You running a hobbs switch on the fuel pressure? Looks exactly like a hobbs switch that isn't set correctly. Ends up turning the nitrous on/off/on/off over and over.

I should clarify on the nitrous tune with timming pulled it made 507/469, I just wanted show the difference from the 485 I got with the crappy exhaust setup to current with no other changes. Timming was at 29degrees on the 524 run.
Also I'm not trying to run the tuner down, he's been tunning a long time, I think he assumed my gauge was broken because the pressure was so low, but it's working fine.

It has the plug n play racetronix hot wire kit, as far as I know it's on right.
