NOS: The Ultimate Nitrous Oxide System for Performance Enthusiasts

NOS, short for Nitrous Oxide System and also a brand name under Holley NOS, is famed worldwide for its cutting-edge automotive performance enhancement products. NOS specializes in nitrous oxide injection systems that dramatically increase engine power output by introducing additional oxygen into the combustion process.

What is Nitrous Oxide and Why NOS?

Nitrous oxide (N2O) molecules consist of two nitrogen atoms bonded to one oxygen atom. By weight, nitrous oxide contains 36% oxygen, compared to air’s 23.6% oxygen content. This elevated oxygen level allows engines to burn more fuel during combustion, delivering significant horsepower gains. When nitrous oxide is released from pressurized liquid form, it rapidly evaporates, cooling the intake air by up to 80°F. Cooler air is denser, increasing oxygen concentration and further boosting engine performance.

NOS systems use this principle of chemistry and physics to smartly boost power, making them a favorite among racers, street performance enthusiasts, and tuners.

How NOS Systems Work

A NOS system comprises a pressurized cylinder of liquid nitrous oxide connected via hoses to electrically controlled solenoid valves. These valves regulate the flow of nitrous oxide and corresponding fuel into the engine’s intake manifold through injectors. The accurate control of nitrous and fuel ratios is critical to prevent engine damage and ensure maximum performance.

• Activation is controlled via throttle and manual switches.

• Pulsed nitrous delivery technology offers precise control.

• The nitrous oxide breaks down into oxygen and nitrogen in the combustion chamber at around 565°F, providing more oxygen to burn extra fuel and nitrogen to suppress detonation.

• Well-calibrated systems optimize timing and fuel supply for safe, powerful results.
