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.

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...
