intake manifold? or turbo air intake?

intake intake, the one that the air filter goes on..ahah

The thermal properties of carbon are good for making an intake out of so it's not a bad idea. That being said, you'll probably get about another .1 hp. If you just want to make something out of carbon, go for it! Not worth it performance wise though

Carbon fiber has many similar properties to fiberglass. If you can get use of an industrial autoclave, you can make it lighter and stronger as the vacuum and heat curing makes the cf compress and become more bonded.

usually when you say intake, most of the time people think you are talking about a manifold..
and what job is the carbon fiber going to do that a chunk of 3" bent steel tubing wouldnt do just as good? with way less work..

2 reasons I can think of.... first, carbon fiber has a very low rate of thermal conductivity. Referring to this chart
here, carbon fiber isn't listed, but fiberglass is. Aluminum is 250, copper is 401, steel is 43 and fiberglass is .04.
To figure out how much energy is being transfered, take the above coefficient, multiply it by the area (meters squared) of the pipe, the difference in temperatures, divide by the thickness of the pipe and that'll give you the rate of energy loss (watts). If you want to take it a step further, rate of energy loss times mass flow of air divided by specific heat capacity will give you temperature gain of your intake air. Figure out the density change and therefore amount of oxygen you're losing and that ratio will give you your drop in power!
Second reason is that it looks pimp

ok, well your going to gain .01 hp from that pimp looking intake..

This is like any battle of the minds..
Why must there be a power gain from it? Lowering your car, looks good.. most do it. Any performance gain? No.
Koady, here is something that will surely turn the heads. Make an intake that will form and suction to the hood, where you will have a hood scoop. RAM-AIR !!!
However the stock intake on a stock or even pepped up motor is more than sufficient.

I beg to differ
I think the stock intake is fairly restrictive. Koady needs ram air.

does this intake look restricted? it may not be IDEAL, but i know it flows way more than enough air for my VNT..
its a stock TD turbo intake tube, with a chunk of ricer intake clamped onto it, and a washable neuspeed (prolly just a re-branded K&N) air filter..

No power gain but rather a gain in handling, to a point of course, drop it too far invert the control arms and your car will handle like a$$.
I say build your cf intake and then show it to us.

If thats the case, then an inch of lowering will be excessive. The Control arms are almost parallel.
I suggested the CF intake to a ram air trans am type hood scoop

What I'm tempted to do is make a rad support out of CF and make the top few inches a ram air running into a 3" CF tube, going through a stock style air box, then down to the turbo.. stock looking, large ram air from the front of the vehicle and a little bit of bling under the hood
So many projects I want to do! haha

my last mk2 had 2" drop coils in it, all the way around, and it handled like a MOFO.. control arms were parallel with the ground.
