Okay, one at a time. No need to push, there's plenty for all.

Nah, just really good marketing at work. In their minds NOS = nitrous oxide

Exactly why the shotgun shells. :p Not to mention that IRL, NOS is crap compared to even a Zex "Newbie Nitrous", never mind a good NX wet kit. Stupid 2F2F wannabes ... "d3wd, you got nawz!"

One of the reasons why N2O is used is that when it's stored under pressure it becomes a liquid. When it undergoes a phase change from liquid to gas at the nozzle going into the engine, it does a tremendous job of cooling down the air/fuel intake charge (or just air on fuel-injected motors), which not only improves horsepower, it reduces risk of detonation. I do not think pure O2 would have this effect, and the detonation issues would probably be unworkable.

All materials do that. You compress iron gas and it forms a liquid... release the pressure on the liquid iron and it will cool the iron gas (of course this is at very high and extremely high temperatures). Same with liquid oxygen, same with liquid helium...

yah, but I wouldn't want to be driving around with a cannister of liquid oxygen in my trunk. I mean, its the other part of rocket fuel, to mix it with the other combustable (not sure what it is) and it makes that stuff BURN!!!!.

its like a fire-extinguisher, exept the opposite. If you took a cannister of liquid O2 (my bad. I hoped you would have know what I meant.) and sprayed it on a fire it would incenerate any combustables in the area. That includes you, mate.

Liquid H2O... :)

Liquid H2O... :)


When did they figure out how to make H2O a liquid? ;)

omg not liquid H2O, that stuff is flamable :)

I know that, I was just saying that the cooling-while-expanding thing was not a reason people use N2O over O2 as both gases do that...

And there are many different types of rocket fuel you know... Solid propellants, different liquid mixtures, but the one you're most likely talking about is straight up hydrogen combined with straight up oxygen.

Because it SUPER cools the chamber, making it a natural DETONATION preventer along with super condensed air :D

<---- teeth chatter at the sound of "running over wires" ;)
