Interesting!
I don't have an answer to your question but I've measured underhood intercoolers that either have no airflow through them (Peugeot 405 diesel) or reverse airflow (my initial underhood intercooler installation on a Nissan Maxima V6 turbo). The other day I was looking at a current turbo Mazda that has an underhood intercooler and no outside ducting to it at all!
Remember that in most road car applications, the intercooler acts as a heatsink basically as much as it does as a heat exchanger - and as a heatsink, it can transfer air back to the intake air when off boost.
