Cars Shuts off
i am having a problem with my nitrous set-up i am running a 75 shot with colder plugs, rpm window switch ,warmer ,etc and my problem is when i spray my car and i left off after fourth the engine shuts off any reason for this? i have never sprayed 1st 5th or 6th....

Actually, after a bit of driving, the popcharger issue goes away on its own. Or, you manually reset your ECU to get rid of that problem.
As for the OP's question, I haven't the faintest clue without more details. What exactly does the car do? What are you doing when the car shuts off?

I've experienced the same exact thing, it means your running too rich so your drowning the engine in too much fuel causing the plugs not being able to spark, thus causing the engine to shut off. This usually happens when your bottle pressure is lower then the recommended pressure thus causing an irregular nitrous/fuel mixture making the mixture too rich. For example: If you were to spray all of 2nd, 3rd, and 4th gear, by the end of 4th gear your bottle pressure would be lower then what you started with, thus making too rich of a mixture.
Try spraying at 1100 psi, you should be fine, that's what I spray at and the air fuel is steady at 11's.
Do you have a wideband, and what are your jet sizes

1250 psi is really high. You want to be between 950-1050, 1100 at max.
Why are you putting it neutral? Why not just shift into 5th or stay in gear then slow down?

now I've got another problem, when i run my car, after a couple runs maybe 5 or 6 2nd to 4th gear 40mph rolls my car makes a noise that sounds like metal pieces loose inside the engine... I've checked oil and i haven't noticed any power loss i actually think its running better but that noise scares me. The noise is completely random so i cant even record it

If you have a spacer check to make sure that the strut bar isn't in contact with the plenum. On cold starts it isn't touching but after getting on it and its up to operating temperature I think the metal expands and then it is touching on the left side. Is it vibration? This probably isn't it but nitrous runs seem to increase engine operating temperatures...just a thought

it could be a number of things. While it is doing this have you gotten out and checked to make sure there is a clearance between the spacer and plenum? Like stick a business card underneath from the right to the left,

Most things under pressure are cold. I am mentioning this to the OP because I have this problem right now. I'm just havn't had the time to go get spacers to increase the height of the strut bar.

I'm telling you that you're wrong. Nitrous oxide will lower the engine temperature.
And no, things under pressure are not cold. I guess you don't know about the ideal gas law (and other gas laws) - PV=nRT. I'm not going to explain this to you, but just know that things under increasing pressure increase in temperature (unless you change volume or the amount). Things under pressure are KEPT/FORCED cool, however, for varying reasons such as reducing reactivity, change in phases, etc.
BTW, I'm almost 100% sure that his metal clanking noise has nothing to do with the plenum hitting the strut bar, so give up on that.
