Ron,
Good to hear from you again.  I thought you had dropped off the end
of the earth.  Are you still running "plugs up"?  I heard your turbo
didn't work out but nothing for a year or two.  I've heard a lot of
talk about electric fans but have been pretty ambivalent for the
reason you stated.  I saw an EZ with a conical fairing from the
flywheel to the end of the prop extension that had big glass fan
blades fastened to it that pretty much dominated the cowl exit.  He
claimed that it helped his ground cooling a BUNCH.  Maybe something
like that could work.
Don't be a stranger .... Jim S.
