Nice looking system!
Heat would be elevated and retained in the turbo after shutdown, no doubt about that. If these turbos can take it great, but for how long? If this is a racing application life is measured in hours not thousands of miles. Engine oil type must be a consideration as well. The specific "HighFlow" turbo mensioned has small clearances that are less tolerant of oil coking. Any metal covered in a blanket and cooked will have greatly decreased life expectancy. 321 stainless or inconel would last longer than typical 304; standard steel would be a pile of rust in a couple weeks.
Great solution for a race car but I would check with turbo manufacturers before using a blanket on a street car.
