with that gold wrapping stuff.....?
Well anything you add is going to be of some benefit; the real question: is it worth it to you? I'm putting DEI Cool Tape on mine, then exhaust wrap. My engine bay gets hot as a mofo!
I don't think it is going to make much of a difference pre-IC. The heated air charge inside of that pipe is probably hotter than the engine bay air.
In Jeremy's case, his top mounted setup is suffering from radiant heat, so he has to take measures to help the situation. However, Eric's setup or most bottom mounted one, don't really need to be wrapped on the hot side of the charge pipe (pre-IC). You'll be most likely not seeing any change at the IAT sensor after all your trouble, so it might be pointless. My 2 cents!
I'd say that since the chargepipe leads to the FMIC, its best to not wrap/insulate it because the whole point is cooler air. Yes, you get better flow with hotter temps, but its self-defeating since any decrease in temp is worthwhile. The flipside of the coin is staggered piping, like 2" hotside and 2.5" coldside, where you (theoretically) get better pre-IC flow from the smaller pipe, while the cold expansion helps further cool the air.
I've been kicking around trimming the rear underhood bracing, like the back-center section, to allow for more venting. The gap is small even without the hood seal, and even more drastic measures would be better (like rear center hood louvers). Problem with those is keeping the elements out of the bay...
