It may be a work around but not very realistic unfortunately. Climbing was an auto rich operation.

Would be good to get to the bottom of this one - what factor is causing the difference in cooling efficiency I wonder?

The following is straight from the Spit pilot's notes:

ACTIONS AFTER TAKE-OFF
Close the radiator shutter (unless a high power climb is done, when the lever should be a little forward).


These aircraft are designed to fly at fairly high power settings with the radiator in the closed position (it isn't actually fully closed of course but in the minimum opening position). Slow speeds and very high power settings are the exception I think.
