Paul,

    An alternative to the pickup truck test, how about statically testing
the rad by flowing hot tap water through the core and pumping air via a
large fan.  This way you can monitor temp, pressure and fluid flow rates
more easily.  I'd love to do it myself on my new rad just to gather the data
which could be extrapolated to flight conditions.

    Darn it all...  I wish I was retired.... so I would have the time to do
all these fun things...   Maybe I can talk Jim into doing it...  :)

BTW Neil the other thing you will need besides the 5 HP squirell cage 
blower is a 150 HP (111,900 watt) water heater :-).
