Spoke with a friend who is a science teacher...
She said that the waterhose analogy is not quite accurate due to liquid vs. gas...whatever...
The opening in the orifice (jet) is smaller than the opening at the bottle. Once the maximum flow from that orifice is reached back pressure will begin to build in the hose until it eventually blows apart. That is not to say it will blow by 1500 psi but it will eventually blow...spraying nitrous into the engine bay.
Now, will a given jet flow more at 1500 psi than it does at 1100 psi? Probably so, I dont know. It should continue to increase the amount of gas released until it reaches max. and back pressure starts to build. If 125 was the true max I would think that everyone who accidentally overheated a bottle would be blowing nitrous lines. In other words there might be some safety margin built into those ratings. Not saying that the jets are over-rated just that a jet capable of flowing 125 at 1100 might flow more with increased pressure until it starts to build backpressure.

FYI, take it for what it's worth.
I just got off the phone with NOS, NX, Nitrous Works, and 2 local speed shops. They all say more pressure = more nitrous. The companies that make your jets said this, if you choose not to believe it, be my guest. Call them yourselves. Doesn't matter if you're running wet or dry, more nitrous pressure = more nitrous to the engine. NOS even said that if you're jetted for a certain HP with a specific solenoid and you change the solenoid to one that flows more, you will be spraying a bigger shot through that same jet.
I will also go so far as to say yes, there is a maximum pressure at which a jet will not flow any more nitrous, but it's not in our operating range.
Can we end this now? I'd hope 3 manufacturers of n2o systems and 2 speed shops know what they are talking about, after all we use their products.

Very interesting. Thanks for the info.

I personally have no experience with "nitrous fires" myself, so I guess that's as far as I can comment. I have theories, but I don't want to post about something I'm not 100% sure on.

Here's what I have to say, and I've said it like 100 times in this thread. Tweety Bird is incorrect in his statements. A dry kit jetting to 125 hp, will not all the sudden make 150 hp when the pressure goes from 1100 to 1500. Therefore, toasted chicken is wrong... (and you don't need to monitor a dry kit's increased pressure over a wet kits - his initial false statement)
There is no doubt, and no one is arguing that pressure does not effects hp, that's a given (until the maximum flow is achieved). Tweety bird says on a dry kit, when the pressure gets to 1500, your 125 jets magically turn into 150 jets. Re-read all the posts from start to finish, I am 100% correct in my statements.
