Turbocharger insulation kit on gt2871r

I just got finished installing a DEI turbocharger insulation kit on my gt2871r turbo.
This consists of wrapping the downpipe in insulating wrap, and then wrapping the turbo with the same type of wrap followed with the reflective material on the outside.
This is supposed to lower underhood temps, and probably other benefits that I am unaware of. Feel free to comment.

Nice, are there any other benefits other than being able to "touch" it while its hot?

should spool a tiny bit quicker and keep things cooler

You should wrap the manifold too for the best result.

just hope you dont get any oil leaks on that dp....FIRE

The wrap needs to be sealed other wise you will just end up causing the DP to crack, same goes for the manifold. The reason to seal it is because the wrap will trap moisture between it and the metal.

I might wrap the manifold in the future, when I take it off again.

There hasn't been any oil leaks onto the downpipe since I've owned the car.

If it traps moisture, wouldn't this moisture be evaporated as soon as the downpipe heats up?

yes, but it fatigues the metal which then cause it to crack. This has been an issue for a long time which is why the companies that make the product came out with a sealer that is applied to the outside of the wrap so moisture can not get between the wrap and the pipe.
