Phil,

The attached picture doesn't show my ram air intake very well, but it operates like you described below.  It uses a rectangular filter element.  If I had it to do over, I would probably have used aluminum.

Bill B:   Don't know if this idea works for anyone else, but my plan is
to have Ram air enter from front of cowling straight into the intake
plenum, with the only intermediary being a box with a diverter flap
(that will lie flat on the bottom of the box for cruising).  When on the
ground or close to it, where dust and FO's are likely, the flap goes
vertical with the pull of a Bowden cable, blocking the ram flow, and
opening the inlet from the bottom of the box, which is fed by a filter
(which could be mounted remotely, if space is an issue).

   Anyone else set their intake up in this fashion?

Phil   RV-10 airframe almost done, 20B overhaul comes next
