Standard temperature and pressure my friend. the idea is by warming up the bottle you will increase the pressure differential between the atmospere(14.7psia) and the bottle (900psia). The greater the pressure differenttial and higher the mass (and volumetric) flow rate out of the bottle. The highe the mass flow rat the greater the amountof oxygen inserted into the motor the greater the amount fo fuel you can burn. More fuel burning under normal conditions the greater he amout of power the motor can put out. As youy hit the Nitrous. The expansion of the gassed will cause the bottle to cool down significantly. As the bottle cools down the gassesb will contract and the bottle pressure will frop dramaticaly. This pressure drop will result in a unreliable system and give ou inconsistent power levels based on the varience an NO2 O2 flow
