Bottle pressure, Bottle pressure, BOTTLE PRESSURE !!!!!!!!
Just installed a gauge in the car, and with the bottle temp the same as Friday night (82-84 degrees) the pressure is sitting @ 750psi ![[Roll Eyes]](rolleyes.gif)
Yes Aaron, you were right ![[Wink]](wink.gif)
I am installing a bottle heater tonight so I can make a real pass at the track
We'll see what happens Friday night

not that much lower than the ideal 900-1200 though, right?

You're right, its not much different
BUT, the system is calibrated for 900-950 psi minimum. So @ 750 psi, the car would be running VERY rich !!!!

I knew the pressure was way low by the feel of the bottle. 1000-1050 psi the bottle will feel toasty. The difference is night and day, obviously, haha.... Now once the pressure is up to par, don't forget to shift As soon as you feel it hit, you'll be clicking off second gear ![[Eek!]](eek.gif) LOL

I knew someone was going to bring that up ![[Razz]](tongue.gif)
The only time the nitrous really felt like it hit hard, 2nd gear was on me so fast, I didn't have time to think about it and not only bounced off the rev limiter (MSD) but I flat missed second gear in the process
I have just about got everything hooked up (still down at the shop right now) I will test it on the way home. On my street tires there is probably going to be a bunch of this ![[burnout]](graemlins/burnout.gif)

750 psi vs a 1000 psi!!! HAHAHAHAHAHA It's gonna feel like a 500 shot compared to what it was before....
750psi would make your car run like a pig... Just be careful about anything higher than 1100..... Just as low will make the car run rich, high will make it lean.... memba that!!!!

Guys dont put your bottle pressure over anything more than 1000 psi if nothing else just dont do it for me ok?
1100-1200 nitrous does weird shit under them pressures but one thing it doesnt do is work well with any of the off the shelf kits.
