One thing I've pondered is that the intake piping between the air filter and turbo is not particularly generous and also runs right over the top of the hot engine. Strikes me as being sub-optimal. I thought perhaps in the case of an intercooled setup this may not be very relevant but it'd be interesting to know just how much pre-heating of the intake air is happening pre-turbo.
The air coming from the turbo is much hotter than the engine bay. So the pipe over the valve cover probably cools the air more than it heats it. Marginally of course....
