Your question is a good one, but bottle pressure is set at 925-950, for more reasons than H.P. The jets are calibrated,and work best at specific pressures. Nitrous is one of the most finicky power adders. With a bottle pressure as low as 750 you run the risk of too much fuel and not enough nitrous, which can squish ring lands. if you want less horsepower Go down on your jet sizes
so my times are not that bad for a 100 shot with 750 psi.?
I placed my bottle under the hood in the staging lane to try and rise the press. but 750psi was all I got

What is your N/A time? No affence dude but with good tires and driving that car should be doing that without the nitrous. I'm not flaming just think your car has more potential, nothing more than constructive criticism, no harm done. Good luck Jerad
