FAQs

1. What is the fuel ratio for NOS? Nitrous oxide (N2O) is not a fuel itself, but it is used to enhance combustion in an engine. The fuel-to-nitrous ratio varies depending on the setup and engine type but is typically around 11:1 to 12.5:1 for gasoline engines.
2. Are all nitrous jets the same? No, nitrous jets come in various sizes to control the amount of nitrous oxide and fuel mixture injected into the engine, so they are not all the same.
3. What is PPH in nitrous? PPH stands for “Pounds per Hour,” and it refers to the flow rate of nitrous oxide from a nitrous system. It helps determine the power increase (in horsepower) provided by the nitrous system.
4. How much BHP does NOS add? The horsepower increase provided by nitrous oxide can vary widely depending on the setup and the size of the nitrous shot. A 100-shot of nitrous oxide might add approximately 50-100+ horsepower.
5. How much NOS can a stock engine handle? The amount of nitrous a stock engine can handle depends on its design and condition. Generally, small shots like a 50 or 75-shot are considered safe for most stock engines. Going beyond that may require engine modifications.
6. What are the 2 types of nitrous? The two main types of nitrous systems are “wet” and “dry” systems. Wet systems introduce both nitrous oxide and fuel into the intake, while dry systems only introduce nitrous oxide, relying on the engine’s existing fuel delivery system to provide the required fuel.
