Steve,

   I may have missed something in the fury of posts but does your current version

of scoop still have the funnel like taper from the opening to the NACA inlet?

  If so this will be a major bottleneck and restrict airflow. To make your new scoop

work efficiently you may have to open up (remove) the NACA inlet. IMHO

Snip.

 

What I’m trying to do is augment the existing scoop, with a “bolt on” scoop ahead of it, which will capture air outside of the boundary layer, i.e. high speed air, to improve cooling.

 

I made a scoop first, that while it worked somewhat, does not exclude the boundary layer air.  Also it’s kind of like a funnel, with the largest are at the opening and tapering down into the existing scoop.

 

I hope that makes some sense.
