Nitrous plumbing A1A...??..

Personally for a small shot, I would avoid the hassle of artificially heating the bottle and just jet to typical ambient bottle temps. Having O2 data available would make it easy for you.

The system that's currently on my car has one of those dial-adjust fuel pressure regulators of the fuel side, along with a restricted return loop to the tank. FPR allows me to quickly/easily adjust nitrous fuel pressure in 1/2 lb increments to compensate for bottle temp. The return loop keeps the nitrous side of the fuel system constantly bled. I installed the return loop for just peace of mind. I used to worry about air getting trapped in the dead-head, possibly letting nitrous get to the bars way ahead of the fuel after I took out the bang button.
