On the other hand, since 99 % of what we do is at the eye-ball engineering style - any examples is bound to be helpful.

What about the adjustable inlet and cowl flap interconnection being of any help.

 

I can buy a lot of cooling capability and fit it into a BD-4 cowl. I could then limit flow through the cores with a variable inlet scheme. I have had to add pancake fans to keep temps under control when a problem occurs on the false grid after the signal to start engines. We could just turn on the fan and keep running. Piston cars would have to shut down and risk boiling the fuel in the carb and flooding. We beat other cars more than once who couldn't restart after going to operating temp and shutting down for a while. 

 

Once I added the biggest radiator Griffin could make I had no such problem again and pitched the fan. But I note that just a small fan could cool enough to allow idle speeds all afternoon. Idle is 2,200 RPM and never a drop in the catch tank.
