It seems like a good idea, and it may keep the underhood temps down, but where does all that heat go? It stays in your manifold. It's like putting a blanket on your exhaust manifold to keep it warmer, longer. The consequesces? Cracked and warped manifolds. So if you're considering putting a blanket on your turbo manifold, do it a favor and just leave it alone. Unless you like replacing/fixing cracked manifolds often.
Also, if you do have a crack in your mani, and you have it fixed, make sure to have it machined because they often warp, which is what causes the crack in the first place, and if it's not perfectly straight when you bolt it up to the head it will cause stress resulting in more cracks.
