[QUOTE="yamafitter, post: 1108941, member: 15141"] Most of the power gains from using Nitrous Oxide (N2O not NO2) comes from the chemical breakdown of the gas forming free oxygen atoms to aid combustion. This allows the introduction of more fuel to be injected into the combustion chamber that can be completed ignited. The power gains are therefore a product of the extra fuel being burned by the additional oxygen being supplied by the breakdown of the N2O. Early automotive applications use solenoid valves to control the injection at only full throttle due to the risk of an extremely lean condition at partial throttle due to disrupted fuel flow. The newest systems have stage valving which allows better control of the N2O injection and increased power gains over a range of throttle positions rather than the old all or nothing system. There may also be some small gains from chilling the air/fuel mix increasing the mixture density but most of the power gain comes from increasing the amount of oxygen available to support the larger fuel charge.
