I would try aluminum tape for radiation shedding of the turbo
after shutdown. Just apply it to the cowl wherever you want some shielding.
It is sold in almost any hardware, and is designed for high temps.
Aluminum tape alone will
not do it. You should get Fiberfax from Spruce and glue the FF to the cowling
than the Aluminum (or better stainless) to the Fiberfax. The Stainless will
reflect the heat and the FF will insulate the skin from the
heat.

While Fiberfax
sounds like an ideal material for such a problem, let me caution you about
it. I also attempted to use Fiberfax to insulate my lower cowl from the
header pipes. I soon removed it because it was fragile and tore easily,
but more importantly it absorbed oil like a sponge. I could just
see it sitting there oil soaked waiting for the right combustion event.
I removed it and found that aluminum foil worked just
fine and was much cheaper and less fire prone. As long as you are not
applying the aluminum foil to the headers or turbo pipes them selves, it will
work nicely. Now, if you are going to wrap it around a turbo or header
then I agree it will not stand up to the temp/heat.
But, unless you are going to forever have an oil free
engine compartment I caution against fiberfax unless you somehow incase it so
oil drippings will not be absorbed by it.
