heatsheilding and reflection materials
ok so considering the Horizontal Mount W/ducting and fans im working on my car.....i was considering my options for lowering enginebay heat...to minimize the amnt of heatsoak the cooling stuff will deal with...
now a few things...
1. i do NOT want to go to water to air...as thats more electronics that can fail...ontop of the resevior i dont want weight balance thrown off
2. the intercooler and radiator are ducted for outside air via .040 5052 aluminum...
ok so ....i figured wrapping the downpipe with exhuast wrapp would be good...and sheilding the charge piping AFTER the intercooler before the throttle body...and leaving the piping tahts from the turbo to the intercooler unwrapped because i presume taht it radiates more heat than it takes in
(in an effort to have lower intake temps)
also an aluminum airbox thats sheilding duct work into the fender and front headlight...area to gulp up cooler air
..SO.... should i use relective foil tape for the airbox? and sheild the intake air via foil refelective tape?
i hope u guys get my idea....thanks for the intel!

well you have two options for reflective sheilding. cheap,expensive...
cheap..... but works pretty good. thick cardbord with good sized airgap between layers covered in aluminum tape
expensive and only work's a little better. gold adhesive heat sheild, tyvex, Nasa panels all of which are can be found through either BSR products, CV products, or any number of race supply house's

Haven't we ALL heard this
I have been wondering the same thing...the cold pipe coming off my fmic get so toasty from the heat around them.
Wonder if it would do any good to wrap the piping in exhaust wrap?

Header wrap on the downpipe will cool your engine bay down a bit, rotary exhaust is HOT.
You're probably right on that one, though no matter how fast the air is moving, some heat will make its way into the air, especially on really hot days when everything in the engine bay is getting heat soaked. Whether it's enough to matter is something that could be tested by someone with a scientific inclination and a little free time. I'd wager that it's probably worth the few ounces of weight it would add.

well i have decided that with my coming Rtek...ill test the temp differences before and after!
it uses the AFM and the throttle body air temp sensor....SO ill test that!
ill first drive it as it is...(ill take pics of that setup) and log OUTSIDE air temps night and day...log that and use the logs from the Rtek to chart my data!
THEN ill finish up my aluminum intake enclousre and suck air from fender well.... test that and then test the downpipe and turbo wrapped versions....and log all data! night and day!
THEN we shall see how it does.....

I bet the amount of heat that this intercooler pipe could ever dream to add even on a terribly hot day is absolutely nothing compared to what the hot aluminum intake manifold on top of the engine adds after the air has already passed through that pipe...
So does the throttle body, UIM, LIM and the block. They have a tremendously greater ability to add heat to the intake air because they are much more massive and therefore hold more heat. If you don't change these it's pointless to worry about the pipe IMO; it's nothing in the scheme of things. If you want to make this a just for the hell of it scientific project your focus should be on the much more massive and dense intake manifolds rather than the ic piping.
If I wanted to test what the pipe can do to AIT I wouldn't experiment with sheilding or wrapping, I'd head 180 degrees opposite. Freeze the pipe inside ice and then perform pulls. If a frozen pipe doesn't offer lower AIT than a merely wrapped or sheilded pipe sure won't either. The places to make gains in AIT are the intercooler itself and the intake manifold.

Thin stainless steel
I had an issue with heat from the turbo soaking the passenger side brake lines in my road race 2nd Gen. I built a thin stainless heat shield around the turbo turbine. A small bit of ducting in the front signal light hole to direct cold air and the intake and brake lines are much cooler.

Couldn't you acheive the same result (only prettier) by ceramic coating those pipes instead?

I'm in south Texas and on a hot 100 degree day I noticed a 3-4 C drop in AIT (PFC reading). I have both the hot and cold pipes wrapped. The results really surprised me. I was hesitant at first because I didn't want to cover up my nicely polished intercooler piping. With those results I'm willing to sacrifice a little bling in my engine bay.
