wrapping my minfold and downpipe
I have heard that wrapping my manifold and downpipe is bad for them, but have seen no data to prove this, I want to wrap mine and put a blanket on my turbo, because I have heard that you can pick up almost 10 hp by doing this and dramaticly reduce underhood temps which has bee a major concern for me. Anyone have any input on this subject?????

I would not recommend wrapping the manifold, as the heat that the wrap holds in can make the manifold easier to crack (if its stainless steel that is). However, I would wrap the downpipe and hot-side of the turbo.
I have put a turbo bag/shield on mine, but have not wrapped the downpipe.

Wrapping the manifold decreases the life of it. Dezod even does not recommend wrapping their manifolds. You will make it fail sooner than later. And yes it will force the turbine to become hotter and spin a little faster. So, you both are right. But 10hp is not going to register on the butt-dyno, so why take the risk.

I'm curious, why does the blanket and heating up the turbine side make the turbo spin faster? I would think this would lead to more heat soak to the compressor side and make the intake charge hotter.

x2.
I'm curious as well.
Another thought, I wonder how much hotter the oil gets (and/or the coolant, if its a water cooled turbo) when it passes through the turbo, thats spinning a gazzilion times faster than the engine.

The turbine section of a turbocharger is a heat engine in itself. It converts the heat energy from the exhaust to power, which then drives the compressor, compressing ambient air and delivering it to the air intake manifold of the engine at higher pressure, resulting in a greater mass of air entering each cylinder. In some instances, compressed air is routed through an intercooler before introduction to the intake manifold. Because a turbocharger is a heat engine, and is converting otherwise wasted exhaust heat to power, it compresses the inlet air to the engine more efficiently than a supercharger.

I wasn't so much concerned from the performance aspect (i.e. trying to get more HP or something to that affect) as I was just trying to keep under hood temps and radiant heat soak away from the radiator.

Heat is essentially kinetic energy so the hotter the exhaust is, the more energy it has, the more energy it transfers, the faster it transfers energy, the faster the turbine spins.
If you think in terms of energy, it's really simple: more energy means faster turbine.

So basicaly the more heat that goes thru the turbo, the more it can make, and faster it will spool? Also why is it ok to ceramic coat at turbo manifold, but its not ok to wrap a manifold, when it basicaly does the same thing
the coating is very thin compared to wrap and doesn't hold the heat in as well as the wrap would. I have heard of ceramic coating the inside of pipes. this is sometimes done if a customer wants to have the nice shinny chrome on the outside but wants to keep some of the heat down. I think i even seen it done on American Choppers. this may be a great idea i think because it will insulate the heat more from the metal and thus should allow someone to wrap the mani to even further the insulating effect without consequence....this is just a theory though
