The turbine housing is the single hottest thing in the entire engine bay. Logically, covering it with a turbo blanket might seem smart, but in reality, you end up getting it so hot that it can actually deform (this is called "slumping") and that damages the turbo pretty quickly. We have some prototype coatings in service right now as an upgrade, and we actually use a different coating strategy for the turbine housing so it doesn't retain quite as much heat as the manifold and downpipe do. You want to run a big heat shield around the entire system, from the rear corner of the engine all the way around to the far side of the turbo forward of the turbine housing, but you don't want to insulate the turbine housing itself like that.
TL;DR: Turbo blanket bad, downpipe wrap good, heat shield good

Thanks for the info. Blanket removed.
