Just a question, but can carbon fiber heat soak?
If it does would it heat soak more then aluminum?

no one will ever know! because it is hard to compair unless you have the same amount of CF and the same amount of aluminum!!!

By heat soak to you mean heat sink? It does, but not near the efficiency of alloy.

simply based on mass/sq.in. you would have less with carbon

well the idea was brough up about CF intercooler piping.
We have CF intake pipe for our MRoadster, so it was just something that was thought about.

Found a company from Ohio that can make carbon fiber tubing at a decent price $100 = 70'' of pipe.

it is just for looks.

just thought I'd let you know. and the CF would just be sleeved; it's not gonna be just cf piping.

Thats correct, additionally, you cannot use run of the mill epoxy to do this. Garrett said that you will expect to see momentary compressed air temps up to
500 degrees at the hotpipe. While carbon has a lower mass than alluminum, the special epoxy that can handle that temp has a higher mass than the carbon. So
that rules out carbon being really effective. And it would not be any lighter, in fact you would need to make it heavier for reinforcements sake. Real focus should be on the intercooler. What about a relay activated fan setup that sucks air thru the IC at preset times?
