Can someone explain what NOS does?

    it makes you go faster. It shoots into the cylinders by differnt means depending on the engine type and burns hotter than normal gas. Its cool stuff if you just use it a little bit. Its not somehting you want to put in the engine for very long. It has a tendancy to break engines if they arnt built properly. I had a buddy in HS that blew up his honda because he put nitrous in a stock engine and used it alot.

    It chemically alters the density of your air fuel. Allows an engine to burn more gas by adding oxygen to the fill.Typical systems can offer as little as 75 hp to as much as several hundred hp. An engine needs to built differently for higher hp level kits. If you are not racing in mud or drags (sand or asphalt) you do not need it. It may be a great conversation piece, but you never really need it on most trails or around town. /forums/images/graemlins/k5.gif

    NOS is a brand. What they make is stuff to add Nitruos oxide to your ride. First off, if you werelike me, you had an issue of Fourwheeler tucked in your science book during class so here is how it works...cold molecules hug together in a tighter area than hot molecules, they like like to get away from eachother when it's hot.(molecule BO? /forums/images/graemlins/dunno.gif) Anyway how this relates to cars is that as the air goes through your fuel system it gets hot and expands along with the mixed in fuel as it goes into the combustion chamber and explodes, if it is too hot it detonates before it is supposed to and that is pinging, whole diferent topic.

    Nitrous oxide is very cold and what nitruos oxide does is when it is mixed in with the in coming air and fuel it keeps it cold so the molecules pack together making it to where you can pack more fuel and air into the combustion chamber making a bigger explosion and making more HP. It is basically the same idea as a blower but achieves it in a different less stable manner. You have to mix in fuel with the nitrous as it flows into intake manifold to make it work right or the motor will blow up. /forums/images/graemlins/yikes.gif /forums/images/graemlins/thumb.gif
    As far as using it on our trucks...You are not supposed to use it with cast pistons but a lot of poeple do it. A 50 to 75HP shot of bottle is probably the most I would wan't to feed a stock motor but built forged motors can take 200 to 300HP shots.

    FYI: No one really calls NO2 "NOS" (unless you are a rice rocketer) Most muscle car guys that I know call it "squeeze", "bottle", and "juice." /forums/images/graemlins/dunno.gif

    What I was thinking but forgot that some people wouldn't figure that density as I said it meant colder /forums/images/graemlins/thumb.gif

    1. Nitrous Oxide is comprised of 36% oxygen as compared to about 21% that is in a normal atmospheric intake charge--that's about 70% more oxygen! More oxygen means more combustion which in turn means more power (assuming that there is sufficient fuel to burn the additional oxygen!)

    2. So if greater oxygen and fuel content in the combustion chamber cause the increase in horsepower, why not just inject oxygen? Well, the engine would produce more power than it could handle and simply blow up! Once the N2O is injected into the chamber and the temperature reaches 572°F (on the power stroke), the molecules breakdown and the the nitrogen and oxygen molecules are separated. The oxygen is immediately burned and the remaining nitrogen helps to dampen the combustion so that the above problem does not occur.

    3. As the Nitrous Oxide changes from a liquid to a gas, it cools the intake air temperature to the tune of 60°-75°F. As a rule of thumb, for every ten degree reduction in intake air temperature, there is a 1% increase in horsepower.

    I thought the nitrogen breaks off at about 750 degrees. Eh, it gets the point across anyway /forums/images/graemlins/waytogo.gif

    "Nitrous Oxide is comprised of 36% oxygen "

    thought pure oxygen was quite explosive
