Re: Carbon Fiber Intercooler Piping. (wantboost)
well i would layer the resin on pretty good and just sand it, it would be like doing a carbon overlay, just takes a little more time because of sanding and clearing

Tony1 is correct, but for some of the wrong reasons.
CF cloth is does not have a high Thermoconductivity, it acts more of an insulator.
CF has a very similar specific heat as AL if you were comparing equal amounts of mass of CF and AL.
The advantage of the AIR manifold(outside of design and weight) is the fact that the CF matrix transfers heat poorly from the head to the incoming air and retains very little heat because its "relative specific heat" is much lower than AL because a CF Im can be made with very thin, lightweight walls compared to an AL manifold thus having much less mass to store the heat.
With Intercooler pipe its a whole different story however because it doesn't touch the head and have hot coolant heating it up(unless coolant bypass is done). The interior surface area of the IM is relatively small but the temperature differentiation between the IM and incoming air is great thus driving up the IAT's.
On the IC pipe hotside you may have temps ranging from 240-290 F and on the cold side the temps should be brought down to 115-130 F.
The question you must ask yourself is : Is it better to have a insulated intercooler pipe or pipe which is thermoconductive like AL?
The answer is far more complicated than most of you would like.....

Re: Carbon Fiber Intercooler Piping. (dasher)
well that makes sense and i know the air flow of the manifold probably also helps it perform so well... either way this is a fun little project.. in my opinion im thinkin i would rather have aluminum so get rid of the heat..but then also it will get some heat soak as well so you are right that is a tricky question

Re: Carbon Fiber Intercooler Piping. (dornon13)
i dont want an overlay... i want a 100% cf pipe.
i have thought of a way of doing it...
aquacore a male mold... resin the mold a little, add more resin, add sleeve... then plae some of that heat shrink wrap over it and shrink it down... it will squeeze all of the excess resin out and form a pretty nice end product..
i might just say screw it and do metal pipes

You also have to take into account the following:
1)The temperature in the engine bay which is variable dependent upon the location and the speed of the vehicle.
2) The interior surface area (or relative lack their of) inside the IC pipe
3) The velocity of the traveling air inside the pipe
4) The temperature differentiation (or lack their of on the cold side)
5) If you draw heat out of the air on the IC hot-side you actually are making the inter cooler less efficient because the amount of surface area and large temperature differentiation are extremely important factors in heat transfer.

I agree 100%...the main reason i wanted and made one a few years ago was PURELY based on cosmetics...
I wish everyone luck with this as for one...its not gonna be cheaper than aluminum from burns
and two...its gonna take ALOT of **** ups to make on that you wouldn't be embarassed to put in your car 
Morgan (synapse motorsport) has built hundreds of Spoilers, wings, bumpers, body panels for all types of formula cars, etc...far from a backyard hobbiest with an intrest in carbon fiber, it took AWHILE before we had a decent one...We tried both ways, 2 peice mold and sleeve with silicone/air bladder...

i was thinking about this the other day.... if it would be better to have AL ic piping with a heatsink of sorts instead.

It's my opinion that it is better to have an insulated pipe on the hotside and Al pipe on the coldside(as long as the engine bay is properly ventilated).
