CO2 injections?

I read this thing about co2 injection and was wondering what you guys think about it? Im not really positive on exactly how it works so dont bitch me out just yet, but i think it is a bulb that is in your intake pipe that hooks to a line connected to a co2 tank like at the paintball shops and stuff. When you inject it, it shoots this co2 into this bulb and causes the air passing by the bulb to be colder because of the bulb that has froze and the air to go into the intake manifol is colder. Im not an expert on this but what do you guys think about it???

Injecting it wouldnt help since C02 isnt really fond of burning... (used in fire extingushers) and putting it in a bulb in your intake wouldnt cool down shit since air is moving by to quickly (and C02 only cools when expanding... just sitting in a bulb wont cool shit)

the manufactur claims that can be a gain of 70hp, but it has only been provin to gain 40hp on a subaru WRX...

no clue..... (all that i could think of is cooling teh air as it goes into the intake, cooler air is denser hence more 02....?)
btw it will run out , i know u can use it for the front mout intercooler insted of NO.

I saw a kit where if you line up to race, it'll spray out the side of your car into the other guys intake and fuck up his engine.

AHAHAHAHAHA i actually laughed at that, is that true our are you just messing around?

It's true that I read it, I doubt it works, i mean how can you get into his intake from the side of the car....

Ohhh.... What your talking about is that N.X. Express Intercooler Chiller. It Pretty much covers your intercooler with Dry Ice (C02) and it chills the air way down. It works better than Ice because its colder and wont get you kicked off a track for laying water down. you can make a manual one for 30 bucks though.


Work on your descriptive skills... dizamn.

kinda like that, but this one isnt NX and it comes with the adapter to hook it up to your intercooler. But the kit hes selling hooks up through your intake....

how?.............................................. ..........

how what¿ LOL

.

how can u make one ????

Paintball 20oz CO2 Tank 20$.
Screw in tank fitting (found under the Grip on most Cheap guns) 10$

Stop car... walk your ass to the front. Spray. Get in. Haul ass.

Too Inconvinent? go buy a remote tank hose from a paint ball shop (prolly need two since its further away). . aim the hose at intercooler. route hose to cabin. ziptie tank somewhere in reach taadaa!!

yeah, it would be easy to make one, but how long do you want it open for? what if you just barely opened it so it had a small constant flow??

nice!!! i'll try it! tnx!

am i missing something here?? does this increase the TOTAL amount of air going in?? or does it just cool whats already going in?? i'm not understanding how simply cooling a certain amount of air (when the volume at this point in the intake can't be changed) will make such a difference.. i can see it working if the air outside of the filter is being cooled first cause then the mafs will want MORE air coming through the filter.. am i making sense? does anybody know what i mean? or am i just plain wrong.. feel free to flame cause i feel really delayed right now

oh no! we are talking about front mount intercooler cooling system (geto, paint ball v). the co2 will chill the front mount and that will cause the air to be more dence and hence more 02 to the motor!

what? i have no idea what we are talkin about, i dont think i was talking about the intercooler kind, i was more directed towards info on the intake one lol :dunno:

haha i think thats why people are confused.. some of us are thinking about the intake, while others about the intercooler.. two totally different parts in their own respect

If your thinking of anything other than a C02 IC chiller than NO it wont work...

yep..what did u think CO2 in the intake, nope....were talking about the cooling the intercooler.

ok.. so i can still ask the same question.. the air already in the intercooler will become more dense, but does that actually increase the amount of air going into the cylinders? or am i stupid? i know we talked about this before (dense air vs more air) but i can't figure it out.. cause to me, it seems like if you condense the air in the intercooler, you're only condensing a certain amount that can't be increased in volume..

personally i wouldnt even mess with that. i would stick with the classic water/alky injection. spearco makes a ncie kit or you can piece one together on your own. it has a water tank that stays pressurized, you fill that with a water/alcohol mixture. it then has a hose running anywhere in your air stream (before intercooler, after intercooler, after turbo, before TB) then at the end of that hose you have a injector, almost like a fuel injector, this will inject a fine mist of the water/aclohol mixture into your air stream. yeah....there is more to the system but not much more. simple but effective. reason for the alcohol is that it can cool alot better than water. but you can just use water by itself. cooling your air flow doesnt exactly add a ton of HP, but you can run higher boost because the cooler the air the less chance of detonation. if you keep your air coming in the engine at low temp than you can run higher boost without effectively causing damage unless your injectors or something cant handle the extra fuel.

this is something has been used for years and proven to work. alot of people run this system if they dont have the money for intercoolers. or triple the cooling power by having the intercooler and water injection.

just my :2cents:

I believe this is what you were talking about

Dense means more air per given area. By cooling, it slows the movement of air molecules. Normally, air molecules are moving at moderate speed. When you heat them up, they start moving quicker. Just like a pressurized soda bottle sitting in the back of a car, they can become destructive. They move faster because they are given energy via heat. When you cool them they have less kinetic energy and more potential energy. They can also be more tightly compacted hence "dense". The same is true with fuel. If the fuel enters the combustion chamber cool, it has much less of a chance of pre-igniting due to extreme temperatures created in the combustion chamber. Diesel engines actually operate this way(along with the heat of compressing air). You're right that it can't be increased in volume. The volume will actually be decreased but more air can be pressed in behind to fill the spaces. Tried and true it works. Just like alcohol injection that k3smostwanted explained very well. Pretty cool stuff.

so in the end, air flow is increased cause its being condensed??

the way i'm thinking of it is in a tube with flowing hot air.. use one of these things to cool the air and it becomes more dense, therefore taking up more physical space, right? so more air will rush in to fill in the less dense areas and increase the pressure.. in an intercooler, is this the same idea? will the air flow increase because of the lower pressure gradient? or what? think about diffusion (for those who know basic physics)

Hot air takes up more space than cold air... Cool the air and put it in the same container (in this case a Combustion chamber) and more will fit in with the same effort. More air = more fuel = more exhuast gas = boost spikes / on turbos during the winter.

That DEI thing is a load of shit... putting C02 in a bulb in the intake isnt gonna cool anything. C02 has to Expand to get cold enough to be of any cooling value. and at full throttle the air will only make contact with it for a good .001 of a second. (thats why Intake companys dont bother with composite Tubes.)

someone should rig one of these up (not some expensive one like that DEI one) and see if there is any horsepower gain...
