The scoop in the photo would produce a ram air effect, if it is the leading edge into the air stream. If this is on a typical rod, then you have a roughly 3" radiator shell extending out in front that disturbs air flow.
There is not set amount of distance of boundary layer above a surface, there are too many variables.
Look at today's Pro Stock cars, you can bet that the wind tunnel has determined where their scoop opening needs to be for their application.
