    General Nitrous FAQs

    I usually try to help out everyone with their nitrous questions on all the sites that I am a member of, so I compiled a FAQ sheet.


    How nitrous works:

    This Question of the Day talks about how sodium chlorate acts as a way to store oxygen. You release the oxygen in sodium chlorate by heating it. It turns out that nitrous oxide (N20) works exactly the same way. When you heat nitrous oxide to about 570 degrees F (~300 C), it splits into oxygen and nitrogen. So the injection of nitrous oxide into an engine means that more oxygen is available during combustion. Because you have more oxygen, you can also inject more fuel, allowing the same engine to produce more power. Nitrous oxide is one of the simplest ways to provide a significant horsepower boost to any gasoline engine.

    Nitrous oxide has another effect that improves performance even more. When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air. When you reduce the intake air temperature, you increase the air's density, and this provides even more oxygen inside the cylinder.

    The only problem with nitrous oxide is that it is fairly bulky, and the engine needs a lot of it. Like any gas, it takes up a fair amount of space even when compressed into a liquid. A 5-liter engine running at 4,000 rotations per minute (rpm) consumes about 10,000 liters of air every minute (compared to about 0.2 liters of gasoline), so it would take a tremendous amount of nitrous oxide to run a car continuously. Therefore, a car normally carries only a few minutes of nitrous oxide, and the driver uses it very selectively by pushing a button.


    What is the difference between a wet and dry kit?

    A “wet kit” utilizes a fuel and nitrous nozzle. Whereas a “dry kit” simply sprays the nitrous itself.

    Will I blow up my motor if I run nitrous?

    Nitrous will NOT cause any adverse side effects on your engine if used properly. If used improperly, it will be your worst nightmare.

    Where do I route my feeder lines?

    The best place is along your frame line where your existing fuel lines are routed. I recommend using radiator hose clamps for increased durability.

    Can I bolt on the kit and go?
    Yes. Although I would recommend going with colder spark plug.

    Are you running nitrous, CivilEngSI?

    Contrary to popular belief, no I am not. People just use it as an excuse when they get beat.

    Do I need a purge valve?

    No, purging is not required, but it is helpful to clear out any water vapor that has condensed in the line to make sure to get a good "hit". It is also good to clear lines when nitrous is not in use(I.E. after using nitrous at the track when you are headed home).

    Do I need a bottle heater?

    No, however a bottle heater increases pressure in the bottle and makes sure you get a good soid and consistent shot

    Do I really need all those other accessories?

    Blow down tube, pressure relief fittings and all safety accessories are not required, however they are strongly encouraged. Also some Tracks require the blow down tube if not more.

    depending on the limit of your engine... how much power it can handle. Yes many people use nitrous to spool and cool the turbo

    great information.

    but would more power cause more stress to other parts therefore causing engine damage? ie. burns hotter(?), more tq on parts, etc

    If people have ran N2O with over 150k miles with no problems I'm jumping on it

    yes more power, whether a turbo or supercharger or nitrous will cause stress on engine components

    I tried a 75 with a stock fuel pump and went lean as hell just FYI.

    Yeah I'm with this guy.

    I was running a 75 shot wet at first and it wasn't good at all.

    Once I used my Kpro to control the nitrous and fuel, things were a lot better.
