Nitrous oxide is made up of 2 parts nitrogen and one part oxygen. During the combustion process in an engine, at about 572 degrees Fahrenheit, nitrous breaks down and releases oxygen. This extra oxygen creates additional power by allowing more fuel to be burned. Nitrogen acts to buffer, or dampen the increased cylinder pressures helping to control the combustion process. Nitrous also has a tremendous inter cooling effect by reducing intake charge temperatures by 60 to 75 degrees Fahrenheit.
For many applications an improvement from 1 to 3 full seconds and 10 to 15 MPH in a quarter mile can be expected. Factors such as engine size, tires, jetting, and gearing will affect the final results.
A 10 pound bottle of nitrous oxide will usually offer up to 7 to 10 full quarter mile passes. For power levels of 250 HP, 3 to 5 full quarter mile passes can be expected. If nitrous oxide is only used in 2nd and 3rd gears, the number of runs will be more.
