Charge pipe coatings
Who knows the websites for hi temp coatings.
www.hpcoatings.com
www.jet-hot.com
those are the two that i have found already.

I lowered my air temperature about 30 degrees by rerouting the intake piping.

my main concern was for the air/water box getting heat soaked on the way to the track. I know that i have the heat exchanger in front of the radiator, but it still raises the iat more than i am comfortable with.
thanks a lot guys!

Under "typical" driving, it shouldn't make a difference (5 degrees at most I would think) as the volume of air passing through the piping. There really isn't enough time to transfer that much heat to the charged air during "cruising" and especially during boost when it matters. This is not taking into account of the air "bleed out" through the Blitz BOV at idle if it is positioned near the battery near the end of the piping.
After rerouting the intake away from the engine and radiator, I am getting on average 25-30 F lower temperatures, both during steady state driving and during boosted runs.
This also solved a partial-throttle pinging problem I was having on hot days.

Exactly.....mtcook.
Anyone read the remote turbo mounted in place of the muffler article recently in....I think Turbo&Hi-Tech Performance.
They don't run an IC, but use coating to absorb/draw heat from the intake charge to take advantage of its LOOOOONG journey from the muffler area back to the throttle-body.
Very similar to StephenMax setup and advantage.

i have been thinking about the header wrap, but it wont wrap well with the shape of my airbox and bracket. my airbox is about 7x12x4 and i could use the aluminum heat shield material on it.
but you know, i kinda like the idea of a heat coating because header wrap takes away from the bling factor, something that adds to the car just in case i want to enter in a show.
stephen, i would still like to borrow your stock stillen piping just to see the difference in psi.

Heat wrap goes around the outside of the pipe which will keep the exhaust hotter but will make the pipe hotter which will lead to shortened life of the pipe especially if it is not stainless.
Coatings although more expensive will cover the outside and inside which will keep the exhaust gas hotter but shielding the pipe and actually making the pipe cooler. They will also make your piping last longer.

exhaust wrap is just going to reduce the temerature exchanges between the outside and inside of the pipe. in this case with the intake pipe, it will keep the hotter, surrounding air from the radiator and engine block from the intake air inside of the pipe.

I was talking about ceramic coating the exhaust pipes and manifold below the charge pipe. You could heat wrap the charge pipe or possibly ceramic coat. I think that it is possible that there may actually be more heat inside the pipe that in the engine bay depending on where it is and then trapping the heat inside would not be good. I would prefer powder coating, an intercooler, and water/meth injection, but then I am planning on turbo eventually. For a SC I am not sure. I would just ceramic coat the exhaust and get the lower engine bay temps and higher egts.
