Randy,  Thanks for your comments. The purpose of the ram air is to pressurize the plenum, at least that is what I am trying to do with it.  Moving the ram air scoop forward is not possible.  As you can see from the drawing room under the cowl goes away quickly as you move forward.  There would not be room for the large air filter I am trying to use.  Of course we are also talking about MY limitations.  I am hoping someone will engineer a better solution.  Space and weight restrictions make designing anything for an airplane a lot of fun.   Jerry

Jerry,
   I know very little about this stuff, in fact all I know is what you guys have taught me but . . . It seems counter productive to me to be trying to get a boost from using ram air and then making it turn 180 degrees before entering the combustion chamber. Seems like more boost is available the straighter the ram air can travel. Would it be possible to mount your "scoop" on the side of the cowling or underneath and move it ahead  so you could get some semblance of a straight shot through the filter then into intake plenum?

Here is a drawing of an intake for filtered ram air.  It will fit inside a Tailwind Cowl.  I have not yet figured out how it goes together and I am hoping the considerable brain power on this list will come to my rescue. I need to be able to service (install/remove) the air filter.  The air filter is hose clamped over the flange.     Jerry
