Buzz,
The filters you are using are folded like most K&N filters. If you took them apart and stretched the filter cloth out flat, you would find the actual area is a lot more than the cross sectional area of the filter assembly.
The system your builder worked out is a very good idea. The big problem with Webbers has always been that you can’t see them if you put a filter on them. (Of course, you couldn’t see them on the original cars because they had a plate above them, but that was for other reasons).
