CO2 Systems

[blueaccord19]

Hey i jus been thinkin about how to get cooler air from my intake to my engine. I play paintball alot and have a CO2 tank as well as a braided CO2 hose that goes from my gun to my tank. This is the hose http://cgi.ebay.com/ws/eBayISAPI.dll...680664597&rd=1 I was jus thinkin about running the hose in my intake and leaving the bottle in the car where i can get to it, and when i get ready to race or something screw the tap in on the hose which causes it to spray out of the hose thus really cooling the air going into my engine, what do you all think? CO2 is really really cold, made my hands go numb and also its alot cheaper to get refilled than nitrous although it wouldn't last very long at all. Let me know what you think.

I don't think it's a good idea to actually spray c02 into your intake. If you were to take a coil and run it on the inside of your intake and have the c02 exit. if you've touched your braided hose you know it get's cold. something like that but a longer hose going through.

summit racing sells a intake kit to do what you trying to do , i does not spray the Co2 into the engine but has a bulb that sits in the intake track

Don't spray CO2 into the intake. CO2 doesn't burn and any horsepower gains you'd likely get from the air being colder would be lost by the CO2 taking up space that air and gas could be occupying. Like some of the previous posters have said, try to make the CO2 cool down the pipe itself so the air going through it gets cooled. If you wanted to be really fancy, you could get a small heater core or very small radiator and put it in your intake. Connect the CO2 to the radiator inlet and then when the air goes past the radiator/heat exchanger/heater core, it'd cool it down. Not sure if that's very possible, but you could always try it.

here we go rigging shit.....go make a coffee can muffler while you are at it

personally i don't think yellowitr should say anything if it doesn't help. and i think a problem with putting something too big into your intake might restrict your airflow.

I dont really give a sh*t wat anybody wants to say to make fun of my idea, this is a decent idea i think tho there may be some setbacks to it. CO2 is the main gas used in paintball but other people also use nitro in their guns which gave me the opposite idea with a car...but just an idea. but i just am trying to find a way of getting better air to my engine. I have a CAI but my car idles real low and i seem to have a lag when i try to take off so i put my stock intake box back on and it almost seemed like i got better power by putting my box back on. Wasn't sure if it was from the filter being dirty, or if it was just that the intake tube was getting really hot. Anyway i may do something with it thurs and i'll let ya know how it goes. Thanks for the help.

performancetuning...toss my salad

oh and by the way it aint like you added an smorgasboard of info in your reply

blueaccord19....i appologize...im a lil rammy....poked a new bird last night like 3 times..got me feelin a lil sarcastic

the best advice i can give is something i learned about when helping my dad install one in his house, its called a french drain i think, It is a tube that has a bunch of little holes in so that water flowing through it can leak out into the ground. What i think u could do is the same type of idea but wrap the piping around ur intake tube, especially if u had an aluminum intake cuz it would cool down faster when the co2 was sprayed on it, also by wrapping it around u get a larger cold surface area so u cool more air. I have no idea how u could make one for an auto application though

They make a co2 intercooler sprayer if you have an intercooler

everyone should just read quake said. CO2 doesn't burn really, so it's just occupying space in the combustion chamber that could be used for combusting more fuel instead. if you're really bent on using CO2, the last guy has probably the best application. the CO2 version of the ntercooler. though i saw some claims somewhere on here of the CO2 ic cooler making 40-60 ADDITIONAL horsepower <----what? i HAVE to call BS on that one. maybe 40-60 in a 1000+ HP dragcar.

LOL about the new bird by the way ITR. way to go man.

mine would be like that only for a non intercooler aplication, it would just wrap around a cold air intake tube and cool that, what i personally would do is find a thin copper tube that u can attatch to this braided hose of urs then bend that so it wraps around ur intake a couple of times, then drill/punch some tiny holes and spray on i believe u would see some gains

[hotbegel]

sounds like an interesting theory. let us know what kind of results you get.

Isnt carbon part of the product of the combustion of the fuel and o2. If the carbon dioxide is injected past the throttle body, the O2 will be beneficial after breakdown, thats if it does breakdown after combustion (Can it be broken down, because it would seem that it is not efficient and kinda pointless to break down CO2, when it is going to come back out as CO or stay in a CO2 state), but would the addition of the carbon dioxide after breakdown just create extra carbon monoxide (CO) because of the extra carbon that is left (C) and whatever else the extra oxygen (O) molecules go to create in exhaust fumes? It kinda does look like it would just take up space. Also I believe that Co2 is also a by product of combustion. Because it would seem that after combustion, CO should be formed into carbon dioxide, though not very efficient, isnt that the reason why carbon monoxide comes out in exhaust fumes along with CO2? I thought carbon was the base product of anything burned.

With H2O injection, the cooling of the intake charge helps eliminate detonation due to water being twice the specific heat and six times the latent heat of gasoline. I think the water and alky mix would be more sufficient though, but i'll just stick with water at this point. Im just curious, where does the H go? same question can be asked, where does the C in CO2 go?

Anyways, this would be very interesting to see. Has anyone ever injected CO2 in their intake manis or can find a link? It doesnt look very promising as an injection source for the engine, it looks like it would hurt.

I dont think it would break down at all In one end out the other, waste of time.Me and Sofast were talking about my idea though, and he is intrigued maybe we will work something out and test it and let you know. But assuming there are gains u would need parts such as solenoids to make it actually usefull in a car on a regular basis
