What to heat bottle too before a pass?
Here at nitrous outlet we recommend using 950psi as starting bottle pressure. Some people will raise pressure to 975psi and then purge down to 950psi to make sure the line is completely filled with nitrous and start at the tree/or beginning of a roll race at 950psi. The pressure drop from once the heater is removed from the bottle or shut off is completely based off of ambient temperature. It takes between 90-91* of temperature to keep the bottle at 950psi. So if you are on a cool night the pressure will bleed off faster and cause you to have to raise it up if you are in the staging lanes for awhile.

Way to many variables to just say run this PSI. 1069 is the suggest max. anything below that comes with experience.

Thats the gauge I use. Installed right at the purge solenoid (close to the intake)
