Nitrous oxide injection systems, often referred to by the colloquial term “NOS,” increase engine power output by introducing additional oxygen into the combustion chamber. This supplemental oxygen allows for the burning of more fuel, leading to a significant, albeit temporary, boost in horsepower. The magnitude of this power increase varies considerably depending on factors like the engine’s size and configuration, the specific nitrous system employed, and the tune of the vehicle.
The ability to dramatically enhance engine performance makes nitrous oxide injection a popular modification in motorsports and among automotive enthusiasts seeking increased speed and acceleration. Historically, nitrous systems have been integral to drag racing, providing a crucial edge in short bursts. Beyond motorsports, carefully calibrated nitrous injection systems can offer benefits in other contexts, such as enhancing towing capacity or enabling vehicles to operate more efficiently in high-altitude environments with reduced oxygen levels. However, it is essential to acknowledge the potential risks associated with improperly implemented or overly aggressive nitrous systems, which can place undue stress on engine components.
