Try to leave bolts exposed. if you keep them under wraps they heat up a bit too much, primarily the 4 bolt turbo flanges. Expierience talking here.
I have my headers Swaine tech coated with out the heat shields (had to weld up some cracks) and it works just OK. It is starting to peal off. I do have my cross over wraped with normal fiberglass wrap then I used the foil covered fiberglass sheets to loosly cover all the exhaust where I could. I put the foil toward the pipes to reflect heat back in. I have some fiberglass sheet tucked loosly around the turbo and between the intake, another hung loosly between the headers and the block and around the down pipe. Putting the foil backed sheet in reduced my oil temps 20 degrees F around town and about the same at the track.
The sheet is expensive and does not last forever but it works well. I fasten it with Safety wire and metal zip ties.
I buy the Metal zip ties at Harbor Freight. I get a can of them for the same price as a few from the header wrap companies and I can see no difference in function or quality. I'm not a usual supporter of the Harbor Freiaght but these are worth a trip there.

So I am to understand the wrap is the best way to go as long as you don't have a leak engine? Better than Jet Hot and Swain?
Question for azmi951, why do you put the foil/shinny side toward the pipes? All of the install directions I have seen shows the foil side out. Not to say you are doing it worng, I was wondering if there was actually an advantage in your method. I thought the foil side was not just for retaining the heat but also for durability to the elements.

The wrap is the best way for a true race car that gets torn down every 25 hours.
If you have a street car, coat it.
The wrap gets brittle and absorbs oil quickly.

It was the white lightning. The surface was bead blasted and clean so it should not be pealing off.
My car sees a ton of miles (3-4K in the last month) and the wrap/blanket holds up just fine. It is not a perminate heat shield but it lasts as long as I leave it in there.
GCB, I put the shiny side in because the foil reflects the radiant heat much better than fiberglass will. Fiberglass insulates well from convection and conduction but the foil insulates radiant heat best.

T3 Turbo Heat Shield
Whata ya think. Worth the effort to slap it on there?

Power????? The object is less heat into the engine compartment, more energy to the turbo through higher exhaust gas tempsand velocity and most importantly lower engine temps.
