Pure oxygen is very flammable as far as I know. I think a water sprayer system would be way more effective than any gas system, because the evaporation of the water disperses the heat faster.

 

or just rig an intercooler water sprayer, can even spray alcohol, alcohol dissipates heat very nicely.
im personally going with water injection instead of just an ic sprayer.

 

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.

 

Ah, yeah that's right. I shouldn't have slept through chemistry in high school...

 

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.

 

Pure oxygen is not flammable at all. To have combustion you need a fuel. The more oxygen that's present, the more fuel you can burn, but there is absolutely no way that oxygen can burn on it's own.

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.

 

No, it's not safe in this application. If and for any reason their is a fuel provided, it'll provide for a disasterous situation.

 

Actually, this is due to the ideal gas law.
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.

 

Perfect, so i just need a bigger bottle with more pressure.

 

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

 

Exactly.

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.
