found them while looking for stuff in jc whittney's its a c02 bottle like any ordinary nos bottle, but intead of injesting it as far as i can tell it just gets shot into the air stream and super cools it?
a link to the stuff jcw sells http://www.jcwhitney.com/CO2-Kits-Accessories/600013959.jcw?in_dim_search=1

Sounds interesting......

<LI type=circle>Revolutionary new system designed to reduce the temperature of the air/fuel intake charge to create more power! <LI type=circle>Easier to install, easier to refill and more affordable than nitrous!
Using the science of aerodynamics, it harnesses the special cryogenic properties of liquid CO2 (carbon dioxide) to lower the air/fuel intake charge up to 60%! Now bigger, better, more efficient engine output is easier than ever! The CryO2 tank and installation kit is the foundation to every CryO2 system! No-hassle refills—tank can be refilled at any welding supply store or anywhere paintball guns are charged. System is easier to expand than nitrous systems. Kit includes tank, mounting brackets, solenoid valve, fittings, 14-ft. braided stainless steel hose, switchess and wiring kit. Only one kit is needed to operate one or all the CryO2 components (sold separately).

$334.99 - $354.99

did some more looking, it doesnt inject into the ungine, just cools the air, and alot cheaper thru advance auto parts then jcw... just getting it and the purge kit with an led would be pretty neat for a few stares ;)

Injecting CO2 INTO the engine wouldn't be good at all, it would depleate all the oxygen in the cylinder and you wouldn't have combustion. The intake set-up has a metal ball that fills and freezes to cool the incoming air. I just wouldn't like to have a huge metal ball in my intake when I wasn't using the system.

For the price of the kit you can get a good Nitrous setup, nitrous also has a cooling affect on your engine as well, and a much larger performance benefit.

yea i just dont trust nitrous with out beefing up the whole fuel and engine systems, seen to many pistons blown apart. not saying im gonna do this, just saw it and figured it was interesting...if i find someone who has and had good luck with it then i might do it

I'm sure the CO2 kit is used to spray onto the intercoolers on turbocharged cars. I've seen them use this on the drag strips. Either Nitrous or CO2. This will help cool down the air.

The Cobalt SS/SC guys use this setup to cool the intake charge going through the blower and the stock water/air intercooler. Some of the SRT4 guys use this as well to help cool intake charges INSIDE the pipes if the intercooler doesn't get IATs down enough. Theres a "SnowMan" kit, if I remember right... and a couple others as well.

Ya. When I had my cobalt ss/sc I knew some guys that had it mist into the condenser

if you really wanted to, you could modify an ic sprayer to spray onto a metal intake tube to super cool the air...

just an idear...

but with a cryo system like this you wouldnt see the same benefits. It would definately cool the intake temps but you'd get better spark and response if it were an alcohol spray as opposed to the co2 setup. the air would be much colder but not as oxygen rich. Thats part of why nitrous works so well. The nitrous not only super cools but also helps bond with the oxygen moelcules and offers a more condensed or "oxygen rich" charge than co2 would. That is why there is a wet system with Fuel and Nitrous... if you run too rich an oxygen charge you will lean out the engine.

With an intake being cooled from the co2 the air would be moving so fast that the temp difference would be minimal at best... someone could always prove me wrong though! :D

Course there's always attempting to pipe your AC into the intake.. Turn it on high and hope for 12's!!! :lol: :D

well i know cooler ait helps, as proof or rather the belief of proof i offer the old coffe can with the fuel line coiled around the inside to be filed with ice, the hi rish intakes with ice dumped under the carb, and on and on. do they work? some say yes some no... for me, i know when the temps go from 90s in the mid day to 60s over nite with lotsa moisture cars run better (btw water atomisers are supposed to be good too) personally i thought this was an interesting idea, and if you were planning a show car or similar you can plumb this with a nozel much like a nitro purge and purge your heart out...or for that matter even if you have nitrous, you can put on a show and save your spray ;) i think its a showy idea more then anything, id have to see someone prove to me that it works with hard numbers on little slips of paper, and not on the companies web site.

I still stand with my opinion that for the price of a CO2 kit, and the other separate accessories, you can have a nitrous kit that will make more power and have the same/better cooling affect.

Doesn't the CO2 kit just increase the benefits of a cold air intake? It cools the piping so the air temp is even lower than with the cold air kit alone. It shouldn't even go into the engine or effect anything...Unless I read it wrong:red: .
A few years ago I knew a couple mid 90's Stang owners who were relocatated the air temp sensor into or near the grille so it would read a cooler temp and inprove performance as well/i dont remember the results.

All the cryo unit does is push Co2 into a metal tube (which is installed inside your intake tubing), causeing it to freeze. As the air passes around or thru it, (depending on the model/brand)it drops the air temp down about 20-40 degrees(depending on outside temp), causeing a more dense intake charge. Which in turn allows more air to be put into the cylinder for combustion. Which is like a a very low end NOs system. Plus Co2 is a lot cheaper to refill than Nitrous and is leagl to have in the car hooked up. Nitrous is only allowed to be transported in a car, not hooked up. Nitrous hooked up in a car while on public roads is a street raceing felony.

Cooling intake air is worthwhile if the air's too hot to begin with. As mentioned above, turbo or superchargers generate heat, which should be removed, normally through an intercooler.

The Cryo system is considered somewhat of a joke among the serious F/I community. The fact that it's sold through JC Whitney pretty much says it all.

More commonly, methanol injection is used to provide supplementary intake charge cooling, as it raises octane along with the temperature drop. There are several kits available. I use the Devilsown kit on my GTO.

One poster mentioned relocating the IAT sensor to a cooler spot. This only works if the temperature it's reading actually reflects the temperature of the air entering the engine. If the air is heated after the sensor, then the computer doesn't have the correct information to calculate ignition timing. Generally, tricking the IAT sensor is equivalent to those stupid "chips" sold on Ebay, which are nothing more than a 25 cent resistor to fool the ECM to thinking the intake air temperature is lower than it is, thus adding spark advance and "improving performance." Pretty much a good way to screw up your engine.
