BTW; Paul, another data point for your cooling system data bank is my
in-cowl and scoop.  The second radiator in the wing root is doing  next to
nothing, yet my coolant temps are fine with one 11 x 16 x 2.5"  radiator, and
a somewhat P-51 style scoop.  It needed internal vanes as well for  uniform
flow distribution through the core.

Go to http://members.cox.net/alg3/ROTARY%20ENGINE.htm and scroll down.

Al

Bulent, Perry Mick and other are cooling fine with no vanes.
Vanes are WW I technology. They are very narrow band devices.
K & M discussed them in a narrow context having to do with
a wall too close to the back side of a core. Move the wall back
a bit and the vanes hurt. Kays & London ignored them completely.
It is far more important to have a properly designed diffuser and a  boundary
layer air bleed.

Al, my oil cooler has about the same duct as your radiator and is
cooling too well.
I think this is a big clue?
