  You are right.  It is important to remember that the majority  of the air
  going INTO most cowls goes right back out of the FRONT of the cowl, toward
  the prop!  Kinda puts "leaks" in perspective, doesn't it ! ? ! <g>
  
  Cooling effectiveness is enhanced by WHERE the air goes.  Cooling drag is
  affected, among other things, by how much of the air moves freely through
  the system and out along the path we want it to take going out!
  
  In a perfect cowl, I'd like no more air coming in than I need for cooling
  and have it all go exactly where I want it to go and OUT where I want it to
  go out.
  
  That sure is easy to say but difficult to accomplish.
