I've seen a problem similar to this that was solved rather easily. It was a
bit of a different application. It was used in a Bd-5 which had a vw engine
used in it. The owner/builder was having trouble in the taxi because it
would overheat due to both  the hidden engine and the pusher prop. His
solution was to build a plenum w/ a flapper valve that would swing one way
when his aux. fans were turned on and then when they encountered ram air
pressure[T-O run].. the flapper automatically swung to use the ram pressure.
I don't know all the particulars right off the top of my head but, I do know
where the article is [ saw it on the weekend] so I'll take a look at his set
up and  post the more finite details next week.

Hope this helps.. [ in more ways than one because I'm going to encounter
this on my a/c as well]
