Paul,

          Got the P Port mockup engine installed and mocked up the slide
     throttle
          and headers.  I think I can get the same length described in
     the NACA
          report for rectangular augmenter by putting it on top.  The intake
          runners will run down to the wing root area in back of the spar
     far away
          from the exhaust.  I can use a small armpit scoop or a NACA for
     engine
          charge air.  The headers are mocked up with PVC pipe 2" ID so
     they will
          be a lot smaller in dia.  I want to put a heat shield around it and
          plumb it up to the augmenter and put the opening in the bottom
     toward
          the rear to get airflow around the headers.  The last picture
     is a 3" X
          10" furnace duct that will be shorter to clear the prop circle
     and will
          flare out in the front to confor to the inner shape of the
     upper cowl.
          The whole cowl will be sealed.

Joe,
   You might consider replacing the elbows with sweeps. I realize you
trying to stay tight, but an elbow right next to the port is likely to
blow out. For 90 sweeps, look for the grey pvc in the electrical
department.
