I think your explanation is much better Stuart. I was in a rush to
catch a plane for Mexico Friday morning and didn't read what I
wrote.
At any rate, I have my new radiator back (MUCH heavier) and will let
you all know how it works some time next week hopefully. BTW, I
don't think the V6 gets nearly as hot as a Tiger, so I feel somewhat
justified in saving $200+ and a couple of weeks. Stay tuned...

I think the deal here is to make the flow within the tubes turbulent,
so
that all of the fluid gets to be right next to the wall at some
point. This
gets back to the laws about heat transfer being proportional to the
temperature difference across the interface. If the fluid along the
sides
of the tubes cools, but the fluid in the center is warmer, then
stirring
things up will get this warmer fluid out to the sides of the tube,
raising
the temperature across the interface, therefore transferring more
heat. How
much of a difference does this make? I'm just guessing, but it must
be
measurable ( a couple percent maybe?) or they wouldn't exist. How
"unturbulent" is the flow in a normal radiator tube? Any "ME's" out
there?
