I was wondering if any one has ever tried to make an intercooler sprayer out of liquid o2. My reason for doing this is that I can get liquid o2 for free and it would be cost effective instead of nitrous for me. What I am thinking is that if I can spray a mist of liquid o2 or the gas of liquid o2 on the intercooler. This will basically have the same properties as an intercooler sprayer. This would have to be done in controlled bursts because liquid nitrogen will come out at -300 degrees below 0. What are the temps of nitrous at as it is coming out of the bottle? Also how cold can u get intake air temps before the air is actually to cold to get fuel atomization?

I would imagine the Space Shuttle people would be better qualified to answer that.

If there was something was better than Nitrous, I'm sure the racers would be using it.

Consider the use of NitroMethane. NitroMethane carries its own oxygen so the more you put to it, the better it runs.

Perhaps, sometime in the future, something will be invented better than Nitrous, but for now, you're stuck with it.

Good Luck

Bad idea. Remember Apollo 1

If the O2 came in contact with a spark or heated exhaust manifold, well, you'd go boom, and that would suck

ok first of just so i get this straight intercolers are a sealed unit right they dont suck in air and then dnt let water get into the intercooler correct me if i am wrone? ya haha i know that but u are taking the same risks when spraying nitrous on the intercooler if the gases from nitrous get sucked into the intake then the car will go boom the fact of the matter is is that i am looking for another method of chilling intake temps and i dont wanna run nitrous through my moter or pay 50 bucks to spray it into the air. i dnt care about any one from space i was wondering if any one has tryed this and also if any one knows how cold nitrous comes out of the tank on to the intercooler. also what tepms does fuel atomization stop and by spraying it on the intercooler do u think i can get the temps that cols to atomize.

N2O (Nitrous Oxide) is non-flamable, but when subjected to the extreme pressure/temps of combustion, the Oxygen is released and facilitates burn. You can use it to cool the IC core no problems, but is more expensive than CO2.

The CO2 when extracted at atmospheric pressure will come out in gas. You will need to make sure you get liquid CO2 in the bottle this will work much better also you want a bottom siphon bottle

He's talking about liquid O2 = Oxygen = What makes stuff burn. If you were hosing your core with it and a spark caught it could easily burn your car to the ground.

P.S. make sure your core has no holes in it which will allow the CO2 into ## intake track CO2= EXTREME LEAN

CO2 does not burn nor would it create a "lean condition" as a hole in your core would make you run rich since metered air is escaping.

Please remain silent on topics you have no idea about

HEY DUMB ASS IF CO2 is non combustable and it gets into your engine with a leak in your core what do you think it will do. LETS PUT 1 and 2 together. DUHHHHHH

Not withstanding your obvious lack of understanding that a pressurized FMIC could not "suck" anything in. It is a boost leak, pressurized air would be escaping from it, not into it

Even if you injected it directly into your FMIC core, an inert gas (CO2) would displace oxygen that was measured by your MAS in the combustion chamber and would cause you to run rich. Opposite would be the case if you injected N2O into the core (which contains/released Oxygen during combustion) would cause a lean condition.

When heated sufficiently, however, N2O decomposes exothermically to N2 and O2.
If this reaction occurs in the combustion chamber of an automobile, 3 moles of gas would be produced from 2 moles, providing an extra boost to the piston, as well as liberating more heat. It also has a number of other benefits. The increased oxygen provides more efficient combustion of fuel, the nitrogen buffers the increased cylinder pressure controlling the combustion, and the latent heat of vaporisation of the N2O reduces the intake temperature

So you agree that N20 is inert except during combustion. BTW, you should provide links to the sites you plagerize from

You should go back to chem class man

Ah contraire, it is you whom should of paid attention in 3rd grade science

NO2
The cost of nitrous oxide varies with the region of the country, however a general estimate would be between $3.50-5.00 per pound.

Margins at different CO2 prices ($US/MSCF CH4)
CO2 cost $US/MSCF Base High gas price
0.75 -2.05 -1.20
0.50 -1.05 -0.20
0.25 0.05 0.80

Thanks for proving me right that N2O costs more than CO2 (math not such a stong pint with you either ). You also have many more options to fill it, paintball stores, scuba shops, welding supply stores, beverage supply cos ...etc.

To recap:
- The original poster guy wanted to inject O2 (Pure Oxygen) into his IC Core, I said was bad idea due to fire hazard.
- I said N2O is inert until engine combustion.
- I said CO2 is inert and will not cause a lean condition even injected into the FMIC core.
And finally
- I said CO2 is cheaper than N2O

I could also post that H2O has better cooling properties than all three listed gasses, but then you'd prol say it (being an inert liquid) would also cause a lean condition.

ok if u people wanna go jack some ones thred go do it to some one els i am asking for ideas and oppinions on makeing a intercooler sprayer kinda like this one but with liquid o2.http://www.dsmtuners.com/parts/product_info.php?cPath=3_134_104&products_id=1009
now the fact of the matter is i have access to liquid o2 for free and i dont want to pay 50 buck a bottel to spray on the OUTSIDE OF THE INTERCOOLER! now my dad deals with this stuff and he showed me how it works and it looks just like a nitrous system but the only thing that i am worried about is that the residual gases will be sucked into the intake and my motor will go boom. now there is a chance of this happinging with the kit i posted above from residual gases left over but my problem is that oxygen is twice as combustible. now i am wondering from people that want to help the thread out how the gases are kept away from the intake on those systems. also at 75 mph is that gas gonna be able to suck into the intake its self and is i5t a big enouh amount that it will go boom.

I'm trying to give you sound advice on the danger it is you are trying to do.

Do me the following favors:
1.) Ask you Dad if he (or anyone at work) smokes while around Liquid O2.
2.) Ask him why
3.) Now take this newfound knowledge and apply to your questions above.

I've a feeling a lightbulb will soon be illuminated

In addition to being highly combustable, oxygen is also a "marrying" element. It will attempt to bond with anything it comes into contact with. This means that prolonged exposure to many different metals causes it to corrode the metal itself. This is also how rust forms. Rust is nothing more than oxygenated iron. Aluminum can corrode as well, although it will take longer than iron. This is usually because most aluminum parts are in fact alloys, which can enhance thier physical properties, such as strength and malliability.

As a result, if you spray your intercooler with raw O2 long enough, you will most likely eat your way through it.

Pure Oxygen can also lower the flash points of other gasses present in the air. This means that if a spark or flame is present in the engine bay while you load it up with O2, it can drastically increase the chance that another nearby gas or liquid will combust, such as gasoline vapor. It will also accelerate the rate at which a burn will occur, turning your car into a giant fireball, all the while feeding it more pure Oxygen to accelerate the burn further.

In short, please do not attempt this, as it is incredibly dangerous.

While C02 and Nitrous spraying of your intercooler might not be as cheap as what you can get oxygen for, it is much, much, safer to run. Nitrous is an inert gas until it reaches a temperature of 565 degrees farenheit. At this point, the 'weak' bonds between Nitrogen and Oxygen are broken, and the Oxygen is free to bond with something else. When all this happens inside a combustion chamber, the result is an exothermic reaction. If you were to substitute NO2 with pure oxygen, the results would be very bad.

If you really want to lower your intercooler temps and turn up the boost a little, try a water/alky/methanol injection kit. Placing a small jet before the intercooler and a larger jet in the upper intercooler piping would get you the gains you are looking for, clean your combustion chamber, and not kill you.

th for the post i decided no on the liquid out and the last person that actually gave advice instead of being a smar @#$ thx u very much. the only thing that is wrong with that post is that it is not a combustible the only thing that it does is acts as a accellerent and lowers the flash point at which things burn at. also just for everyones info it is not illeagle to carry the stuff in your car like slow boy racing told me.
