So...
Have we reached a conclusion on this? I tried to read through the last couple pages but I don't see a definite answer.
Is carbon fiber IC piping a consideration or completely out of the question due to insufficient heat tolerances? From what I have heard, carbon fiber does not absorb heat (or much less than aluminum anyway..), but the resin material can melt past a certain degree temp. I have seen them on supercharged cars, where heat is not as high, but I don't think I've seen carbon fiber on a turbo setup. I really have no idea just thought I'd bring it up, while on the topic.

Our testing showed a temp drop between the intercooler outlet and the intake plenum.
We would not insulate that pipe either. This was a complete stock bodied car and it still had
the hood seal at the rear. You can theorize and guess all day long. We did the testing,
we are sharing what we learned, and anybody can either accept the reality of it, or not.
If you could move even more air out from under the hood and replace with ambient, then you would have even greater temp drops through the stock pipes and intercooler.

Actually, removing the rear seal would likely cause pressurization in that area. If you remember the old american muscle cars, many had "cowl induction". That is because the transition area is normally high pressure and not low. There was a picture here at one point of air pressure at various spots on a 944. That would show where to put vents.
The design of the 968RS vent is that it has a lip in the front of it. This causes a low pressure area right behind the lip (where the hole is). The idea is gasses flow from high pressure to low.

i got lindsey racing hard pipes in dull and got it powdercoated by a friend looks great and some one told me that the less bends and smoother they are the cooler the air will stay.
