Turbo insulation

[nissannewby]

Anything you can do to maintain heat in the system upto the turbine is good.
More heat, better corrected gas flow for more drive on the turbine, so yes it should spool a little quicker and be more effecient.
I have everything wrapped, including my exhaust for about half its length.
Ceramic coating does the same thing.

Do you have any issues with the wrapping retaining moisture? While the point you make is good I have seen exhausts wrapped in that turbo beanie exhaust insulation stuff and once wet holds onto a bit of moisture and the exhaust condition goes down hill. I know it's only minor but something to think about possibly.
