dry ice
what do you guy think about putting dry ice in my intake air box to condense the incoming air. as you know the cooler the air the more power you make. just a thought from a honda owner that wants more power. muhahahahahah

Re: dry ice (94hondaLS)
well it might work a little until the ice melts, and as long as it doesn't block too much air flow. for some more cheap power you could take some flexy hose, take out a headlight and run the hose right through where your headlight goes all the way to your throttle body, that should give ya some powa!

Re: dry ice (MiraiZ)
and all it takes is one piece getting sucked into your engine and you're hurting bad. if you want more power, take your stock airbox off and put a cheap K&N conical filter at the end of your intake manifold/throttle body. It's not an "intake" per se, but it'll get you down the 1320 faster.

Re: dry ice (94hondaLS)
i don't think it'll do any good. The reason colder air gives u "more power" is because it is denser therfore contains more atoms of oxygen. if u have the dry ice in your air box it will just cool the air inside the air box, but u still have the same number of atoms getting sucked in, they're just more packed together. anyway, as the dry ice (frozen CO2) evaporates it will take up the space of the oxygen and will probably do more harm than good.
correct me if i'm wrong about the "same number of atoms going to the engine"

Re: dry ice (splitime)
im gonna go against the grain here (kinda)
say your at the track
between runs you can put a bag ofice on the intake manifold and it will get the IM really cold and that has a cooling effect on the incomming air
but remove the ice before you run
and it dosent do jack **** on the street.

CO2! VERY VERY DIFFERENT FROM O2, I just love the uninformed and the ignorant when it comes to cars... go to school get an education....think! there's no easy way to make your car fast or look cool, it takes work!

Hey *** clown, he's talking about experimenting with ways to make the temperature of the air entering his intake to become cooler. Cooler air is more dense. Denser air has more oxygen per square unit area. More oxygen produces more thorough combustion and results in increased thermal efficiency. Increased thermal effeciency results in more power.
go to school get an education....think!
edit- where's BDC when you need him

Re: dry ice (DMS Racing)
CO2 Displaces O2 and that is why it is used in Some Fire EXTINGUSHERS...
I think we covered that in HS Chemistry. Now what you could do is Place the Dry Ice one the OUTSIDE in an effort to Cool the Air inside. That would have been a More educated and informed Idea.

As long as the dry ice is external of the intake air it can be used to cool engine components (intake manifolds, intercooler cores, etc.). But considering the extra handleing percautions over regular ice and extra cost.....it really isn't much of an improvment over using plain ice. And we haven't even gotten into the possible thermodynamic alterations that may be present with the much lower cooling temps that dry ice would offer. Sometimes too cool is not a good thing. Something to think about.
I've personally used bags of regular ice, N2O cooling systems, and compressed CO2 cooling systems to chill intercooler cores before. I leave the dry ice to keeping my steaks cold.
Trying new ideas is good......it feeds the brain you know.

nice try dipshit, trying to use some mechanical/physics terms to wow the uninformed...wow you are a real genius, but why don't you go back and read his original statement.

Re: dry ice (94hondaLS)
you could make an airbox with a chamber that goes around it that you can put the dry ice in so that it cools the the area around the filter but i dont see getting any major gains from this

Re: dry ice (ridge racer 2)
I have to give the guy for the effort here. It's not that he has a total lack of understanding, he just dosent have a total and all encompasing understanding of how everthing works like all the rest of you, so rather than flaming him off the bat how about just educated responses? It's not like he came on here asking about NAWZZZzz or anything like that. Have an educated discucssion on the topic (or give the link to last weeks educated discussion on the topic if that's the case ) and they'll leave more educated than when they came in.
That being said, even if the airbox was chilled I dont know if that would really give you any real benifits. It's a big deal with boosted engines because the super/turbocharger heats up the air alot, but for a normal NA setup? I dont think it would

Re: dry ice (kingpen)
Yes it can work...not always though.
The extreame cold temp of the ice cools down the sheet metal quickly. When metals get colder their molecules move closer together and the material tends to "shrink-up" or contract. This contraction sometimes is enough to nudge the dent out of the sheet metal.
Another note to add to the dry ice being used to cool the inlet air:
Cooling the air box won't work as well as cooling the intake manifold. The air box (because of material, mass, and distance from the engine) will not be as efficient of a heat sink as the intake manifold. The (usually) cast aluminum intake manifold will have better heat transfer properties than the thermoplastic air box.
