Oxygen is the oxidizer, not the fuel. This is why oxygen is considered not-flammable. However, introduce pure oxygen to a fuel that is burning, and of course it's going to make quite a show.

Even if you didn't, most HS chemistry classes say it's flammable anyway. Basically think of flammable being voltage, you need a positive and a negative, oxygen is the positive, and whatever burns is the negative, however by itself it doesn't do much.

Thats what i meant.. Pure Oxygen... I do alot of oxygen acetylene cutting.. When the oxygen is added BOOYA
But i'm sure it would be safe in this application.

Think about it. Air is nearly a quarter oxygen gas, but it doesn't ignite when you light a match. Making it four times stronger (i.e. pure oxygen) isn't going to change that.

PV=nRT
P is Pressure, V is volume of the container, n is the number of molecules of gas, R is a gas constant, and t is temperature.
When you release the gas from the container, the volume of the gas cylinder will remain a constant, as will the gas constant. The pressure in the bottle will decrease as the gas molecules flow out, and thus, to keep both sides equal, the temperature will also drop.
To get a significant decrease in temperature, you need a lot of pressure, and a large bottle volume... nitrous bottles work great because they are large and the nitrous gases are stored at 900-1200 psi.

I wouldn't it was safe in you engine bay, but then you shouldn't have exposed fuel in there either...

With a small bottle with low pressure, the volume of the lines leading up to the nozzle at the intercooler will experience the temperature drop. You want to keep the highest possible pressure drop at where the gas comes out of the lines... this is one of the reasons why nitrous solenoids are placed close to the engine, as opposed to near the bottle... it allows the nitrous lines to be incorporated into the nitrous bottle volume.
