FAQ's about Nitrous and Nitrous Systems

Q: How does nitrous work?

A: Nitrous oxide is a gas that contains two parts nitrogen and one part oxygen. When the combustion process heats this gas, the oxygen is released. This extra oxygen then supports the combustion of the enrichment fuel the nitrous system adds when it is engaged. The additional fuel that is burned, creates greater cylinder pressure, which makes the extra horsepower you feel.

Q: What is the difference between a "wet" nitrous kit and a "dry" nitrous kit?

A: A wet nitrous kit mixes nitrous and enrichment fuel by means of an injector nozzle that is mounted before the throttle body. This mixture is then drawn into the engine through the throttle body and intake manifold. A "dry" nitrous kit injects only nitrous with it’s injector while at the same time, increasing the engine’s fuel rail pressure to feed enrichment fuel through the engine’s own injectors.

Q: What is better, a "wet" or "dry" kit?

A: It all depends on the application. A "wet" kit is ideal for both normally aspirated applications as well as forced induction applications. It can require a little bit more installation time than a "dry" kit, but is easier to tune if greater than stock HP settings are to be experimented with. A "dry" kit is excellent for normally aspirated combinations that have a return style fuel system. They are very easy to install and are a great "first time" nitrous system. It is not recommended that "dry" systems be used on forced induction engines.

Q: What does it mean to have a 55, 75, or 125 "shot" of nitrous?

A: "Shot" is a slang term for the horsepower setting your nitrous kit is set to.

Q: How long will a bottle of Nitrous last me?

A: That would depend on the size of jet (horsepower) and how often you purge your system. On average a 10lb bottle will last 10-15 "runs" at a 1/4 mile drag strip.

Q: Is nitrous oxide flammable?

A: No, nitrous oxide is not flammable. It is simply an oxidizer that supports the combustion of additional fuel.

Q: What is the minimum RPM I need before activating my nitrous system?

A: We recommend at least 2500rpm as a minimum for nitrous system activation. This ensures that you will not have excessive cylinder pressures that could cause engine damage.

Q: Do I need a purge kit?

A: A nitrous purge kit clears the delivery lines of unwanted air and vapor and guarantees immediate power from your nitrous system. It’s also used to intimidate your competition and shows the world your nitrous equipped.
