C.A.I?, just some quick questions Options

[FallenHero]

Ok, I am gonna get a DR CAI.

There is aluminized steel, and aluminum. I figured aluminum is better, but a friend of mine said it would heat up more than the aluminized steel. BUT, i wonder if the aluminized will rust? Also, has anybody made their own CAI and been hapy with it, and finally, who has a DR CAI, and how do you like it?

[Jeremy1210]

an east cheap way I've seen a CAI without the metal pipe was this guy who removed his box, but kept the hard ruuber tube from the intake. he just attached a K&N to it. He said it worked fine. Don't have to worry about rust, but how would yout stuff rust anyway? I didn't think water got into the engine bay all that much

[Guest_Matthew_*]

that's not a CAI. that's just like a short intake like the INJEN one or Weapon R.


But he does have a good idea though. You can get your self some PVC pipe or that rubber tubing and it should work fine if you a worried about rust.


But I would recommend the DR. CAI. I mean sheez he's a doctor so I think he knows what he is doing. hehehehe

edit: spelling

Like igotta said, what your thinking of is a short ram intake, a CAI involves running a tube, metal or rubber, out of the engine bay away from heat. Usually a cai is placed in a wheel well or housed in the front of the bumper.

I've got the cheap set-up for now (filter on the stock tube and it works well), but I'm planning on making a CAI. There's a how-to on the process of making one if you're good with that kind of stuff.
However, if you'd rather buy it, the Dr.CAI looks like the definite way to go. I sent an email to Dolecek about the differences. It was a while back, but I believe he said that the Aluminized Steel CAI could rust and it would be better to paint it, but for $50 more, you could have aluminum, which is also lighter (if that really matters to you). Hopefully this might help you somewhat.

[Blackcelliman]

I put a filter on my intake with just keeping the rubber hosing. I used PVC piping to fit the K&N on. It worked just fine but I'm soon going to be upgrading to a CAI. Mine works just like a short ram.

[FallenHero]

I believe heat soak is really bad on aluminum though.

[95STCelica]

I have the Dr CAI and i can't complain..if you want pics of it just IM me on PlatinumImpact and i'll send you all that I have

[Neipas09]

I got a CAI and i think it's way better than PVC pipe or using your old tubing. It's powder coated also, so i don't have to worry about it heatin up.

[FallenHero]

I'm just gonna make my own from exhaust piping. Also, i was trying to figure out how to get the filter in the fender, and I don't see a way to do it. The Radiator reservoir is in the way. I wonder if i could get a pipe through where the stock intake gets air.

i thought that powder coating was to prevent rusting not heat soak.

[Neipas09]

Your probly right. I thought someone said that powdercoating helps with heat soak. Oh well, i'll just buy some wraps for headers and use it on my CAI.

[FallenHero]

That's what I'm gonna do. (wrap) Also, i wonder if DR powder coats inside the pipe? If not, it could rust-->major major problem. I wonder if iron oxide helps performance, lol

[Neipas09]

Well it would just rust to the point where the outside is powder coated, so you would end up gettin a larger intake and more air capacity.

[95STCelica]

always good lol

i may have just had a brilliant idea...

[boosted_K2]

oh and as for aluminum heatsoaking yea it is bad, it has a thermal conductivity of 240 J/(sMC^deg.) in reference stainless steel has a conductivity of 14... the ideal material has 0.00 conductivity. thus bringing me to my ingenious idea...

EDIT: just looked this up at dow
QUOTE: "Thermal conductivity - Values usually range from 0.330 to 0.515 x 10-³ gr-cal/sec/cm²/cm/°C."

thats for silicone rubber good stuff, thats y its used for couplings... (silicone rubber is NOT part of my plan, just seeing its conductivity for coupling reference)

ANOTHER EDIT: for any of you who are wondering why the units for my #s are different from dow's units they arent different. gr=1 gram so it cancels, 1 cal = 4.186 J, sec = s, M = cm^2*cm*rho, and obviously deg celcius = C^deg.

I think you learned about heat soak on a few materials today and felt like a lecture. Either way, this is my performance thought. Whithin a year I will: Get a DR CAI, header, and might get the greddy exhaust. (most likely have pipe made for my car) then I'll get a high flow cat. Why keep a cat? so my car isn't LOUD!!!!!!

[Neipas09]

just get a muffler that has a silencer

nope actually i had just finished my physics HW for the day, read this and since i still had it out, flipped back a few chapters and got some #s then followed up with a trip to the dow chemical website... im starting to draw out my prototype of my idea for a CAI, if i get done and it actually works like it would on paper, i may try the same sort of idea for a headerback piping... im still trying to figure out what materials to use... anyone know what the temp under the hood is at on average? celcius ferenheit or kelvin doesnt matter...

[Phat_99CeliGT]

I made my CAI outta 3" PVC piping. Im gonna re do it cause i heard the PVC isn't heat resistant, to use ABS plastic?

[FallenHero]

Does anybody know if the DR CAI filter is actually INSIDE the fender? Or is it just down behind the radiator?

[KAMiX]

K2 - The way I drive, its ****in Hot! I have pulled over randomly a lot to see how hot my pod filter gets, and its pretty warm

Question - How come none of you have talked about using stainless for the CAI pipe? Looks good - not as hot, it doesn't weigh THAT much...

I think it would look way nicer than aluminium or rubber and thats what my aim is, although I haven't figured out where to put the filter yet. I'm thinking below the battery, where there are 2 little vents through the plastic underbody of the car, and also running some sort of funnel/pipe from a gap in the front, onto the filter.

Only thing I stress about is hitting a puddle and getting the air filter wet

[st202gt]

hey you guys tired using manderal bend for making your own C.A.I or air intakes? here what are some realted sitie that can show you how to make your own CAI.tt-cc.com

[95STCelica]

i have the Dr CAI. and yes, it is in the fender it goes straight down to the right if your standing looking at the engine from the front, it is practically fully protected from water ingestion, never have had a problem. Dolecek knows his ish.

[FallenHero]

I think you just maid my decision

[BigEdge169]

If you are worried about water ingestion, just get a CAI or make one yourself and buy an AEM bypass valve to protect your self. Here's a link to a test on it http://www.aempower.com/by_pass.htm

[FallenHero]

It's not the water. I just don't want a long short ram, know what i mean? If the filter is in the fender, it gets cold air. If it's right behind the radiator,,,,,
