This stuff would make great heat shielding. No real experience with it though.

Over the years I have used everything and will offer this experience of mine.

On manifold DO NOT use heat tape or wraps, on my own car I fabricated a two piece stainless heat shield (see my build thread). My previous cars on all kinds of manifolds even with low use heat wrap KILLS pipes on turbo rotaries...

Dump pipe is the same, I use a stainless heat shield only, tired wraps and loose fitting ones but it kills pipes too.

On the turbine housings, it is 100% fine to use a turbo blanket. The DEI ones are pretty good, the thick cast iron is impervious to the retention of heat, but is can warp the housing, so if you have time and space it is preferable to make a heat sheild here too.......... just some can't. its the only area thermal insulation like a blanket should be used if needed.

That is my expereince anyway.

It is not really marketed as a heat shield. but at least it seems pretty cool stuff.
