Bottle Volume and it's relationship to Temperature & Pressure
Bottle pressure is one of the most important factors in tuning a nitrous oxide system. Many people feel that if a bottle is full then the pressure must be right, however, that isn’t always true. Pressure has a strong relationship to temperature. A full bottle can vary from 750 to 1200 psi depending of the method used to fill the bottle. Most nitrous systems are tuned utilizing liquid nitrous, which is denser than gaseous nitrous and more stable. Nitrous becomes a liquid at a temperature of –127°F at atmospheric pressure. Since this temperature is nearly impossible to sustain and there would be no pressure to carry the nitrous where it needs to go, we use the alternate method to change the phase to a liquid by pressurizing it to a level of 735 psi or greater, ideally 950 psi. At 950 psi nitrous has a density of 5.44 lb/gal., bottle pressure is more stable and can easily be sustained with the use of a bottle heater. Many people also feel that running pressure greater than 950 psi will generate much higher flow of nitrous, however, this is not the case. The above temp/pressure chart illustrates the relationship between bottle temperature and bottle pressure. Note that as volume decreases it is harder to maintain pressure and a bottle heater can help ensure better consistency. A consistent bottle pressure provides a consistent amount of nitrous delivered during a given period of time. It’s also good practice to top off the bottle when it reaches a volume of less than 40%. Although a pressure of 950 PSI can be achieved at almost any volume, the problem is that the pressure drop will be much greater than when a bottle is full, and consistency can be affected.
