I eventually used an electric leaf blower to pull air through my d= uct.  I used cardboard box taped around my exit  with the blower = inside. A hole for the blower to remove the hot air.  I was able to ru= n indefinitely just off idle (2000 rpm)  with this setup.  I woul= d eventually overheat either slower or faster, but I could return to that R= PM and it would cool back down.

Don't blow into you radiator.  The high force wind co= uld damage it.  Also, the cardboard seal was important to make sure it= was pulling air through the radiator, and not just from the ambient air ne= ar the exit.
