I would have thought wrap on the charge pipe would increase charge temps slightly....... (as standard, it dumps a bit of heat into the bay.)
why keep the intake heat in ?
would have it would be more beneficial to polish it or paint it black - damn which way round was it that lost heat more effectively ??
in fact weld a shed load of big washers round it and direct some airflow over it
works for processors
where's a decent school science geek when you need one ?

ok very easy science for you guys:
black (or anything dark for that matter) is influenced very quickly to temperature changes in its surroundings. This means it heats up very quickly, but will also lose its heat quickly.
Polished surfaces (or anything of light color) take longer to be influenced by the temperatures in its surroundings. This means it heats up more slowly, but retains the heat for much longer.
Homework for tonight class:
Get 2 ice Popsicles . put 1 in aluminum foil, and 1 in for instance a dark trash bag.
The one in the bag will melt much faster.
Class dismissed

thats the daddy - too early for me
greater surface area explains it all so rougher is best - hence why most standard ones are roughish cast ali then

Buy insulating it, surely you'd be keeping the heat from the engine from the charge pipe, meaning it would be cooler?
i think it would increase temps.
i assume you think that the engine will heat up the pipe. Im my experience the charge pipe can be very hot when the engine is not very hot. So im unsure why wrapping it will reduce temps. - unless its designed to disapate heat.. but i believe they are designed to insulate it.
Sounds to me like having a charge pipe polished inside and black/ rough outside may be the way to go..
either than or get a better intercooler.

your right theory regarding colour is correct; however that is not a correct test as the materials should remain the same for a properly controlled test regarding colour.
If the foil was black and the bag white you may find the ice in the bad still melts faster!

now there is the start of a discussion you don't see often on a forum like this
but yes you're right material is obviously a big factor too.
i agree that in traffic engine bay temps would go up, so in this case the heat wrap may be an idea to insulte the relatively cold air in the charge pipe, but when driving even at low speeds there is a lot of air coming in to the engine bay through the front of the car.
i guess the only way to know for sure would be to mount a temperature sensor in the engine bay (possibly to the under side of the bonnet) and see what temperatures are shown under different driving conditions
then compare this to air intake temps on vag com
you should then be able to determine if u want the charge pipe to be insutated or conductive. same for the inlet manifold
