I've seen the exhaust downpipes insulated before, but I haven't seen anyone go as far as the hot side of the turbo. The kit pictured below was on the car featured on the 900BHP quattro thread

It claims to "virtually eliminate turbo lag"!
What's the theory behind that then?
I can see it reducing under bonnet temperatures but can there be any other real gains?
