Bottle presure Q I have no presure switch on my bottle because of fitment issues, so I wired it on a switch and relay.
I was letting it heat up before a run and I let it get to 1250 psi on the gauge. It did'nt blow off and the car ran really strong down the track.
Were does it pop off at??
Is this bad. I don't want to see my quarter pannel blown off.lol.
It's a tnt bottle 10lbs.

I think most companies aim to have them rupture at 2,200-2,500 psi. I really wouldn't be spraying over 1100psi though. It can take a toll on the solenoid and it'll lean you out.
yep, there's a big difference in how it reacts at different pressures from my experience. but i think it's like what's been said, it's just the overall mixture being a bit "leaner". i made my nitrous passes at 850-900 and see alot of guys saying that's a good pressure, but i've also read people saying it should be up around 1050-1100? hopefully we get more people responding
We run it at 1050 with the nx pressure activated bottle warmer. I think 1200 is a bit excessive. With a big shot it is nice to have 1050 to start because it drops to like 900 by the end of the pass.

the higher the pressure usually means it'll hit a little harder...but you run the risk of freezing the solenoid or running too lean and hurting something. most companies suggest that their system is most effective at a set determined bottle pressure. TNT i beleive tests their kits at 950psi and state that thats where its best effective which is where i try and get my pressure to stay around when i hit.
goodluck.
goodluck.

I run 1150psi, but am a dry hit and fuel ratio will stay the same whether it's 600psi or 1500psi, one of the many benifits of dry. Also, on a dry hit if you up the pressure, it's the same as jetting for a larger hp hit. On a wet kit whether it's a higher or lower press, from manufactures suggested psi, you'll be going lean or rich.

My nx jet card was rated for fuel @ 50 psi and nitrous @ 1050. If you use a nitrous calculator you can figure out the fuel jetting. Usually tnt and nx over jet the fuel by 1-2 steps for safety reasons.
NX's kits reccomend between 900-1050 psi.
That's why theyr second gen bottle warmer turns on under 900PSI and turns off at 1050PSI.
I know NX's blowdown tubes have a rupture disc which is supposed to pop at 3000 PSI. If Memory serves me correctly tanks are supposed to be capable of handling somewhere in the 5-6k PSI range, but I wouldn't test it.

The next run, I cranked up the pressure and the car felt very strong.

I like using mine between 1050-1150, at 900 the hit seems weak with a 150shot but I will not run it over 1200, if its that high, I will purge it a little to lower the pressure some.
