Hi Bill, no I haven’t checked the airflow distribution yet. Once I’m done tinkering around with the exit area I’ll check that to see how the divider performs
and overall airflow across the core.

Jeff,
It would be a good time to check the airflow distribution across the face of the radiator with a leaf blower and a tuft of yarn on a stick as was described by Bobby
the other day. Did you check this prior to adding the dividing vane?

I spent several hours yesterday working on the inlet plenum. First the pinch was removed and reprofiled with a gentle slope. Then I decided to divide the airflow
front and back by adding a divide vane. I simply cut a notch on both sides of the plenum, slipped in a sheet of aluminum and glassed over the seams. Also added some foam core on the inside to aid the back half of the core ... see attached photos. Still
have to examine the outlet diffuser (or none) and/or cowl flap, plus check cowling to see if any inlet area is being wasted.
