Depends on how its positioned and if you have a decent turbo heat shield etc.
Also depends on how you measure it, a set of rollers will make things look far worse than they are on the road, as the fans never mimic 100mph+ airflow
Thats the fundamental problem with the sort of test mike is describing.
Personally though, i think airbox's are the better idea in general, so im not aruging against them, just saying its very application specific.
