  Boy, you catch me every time{:>)

  Thanks for the info Rusty

   Paul,

      I calculate out Rusty's radiator to have a
volume of 17.5*24.25*2.25 = 964 in^3.  Given that he
was running a turbo, he would naturally want/need
more cooling capacity than a NA block.  So his basic
radiator was approx 50% large in volume than two
cores.  Since he could produce up to that much
additional power with his turbo, it would appear
that his is sized about right - perhaps a bit on the
large size since he probably would not run under
high boost at cruise.    MESSAGE CUT TO SAVE DOWNLOAD TIME, ETC

    IBut, in any case, I think your currently
planned radiator size is undersized.  FWIW - always
keepin mind my knowledge of radiators and cooling is
quite limited.

    Your knowledge of radiators and cooling may be
limited....however, my knowledge of radiators and
cooling could be written on the head of a match.
Thanks for your valuable input, Ed.  I was trying to
come up with a radiator that could be placed
directly in front of the NACA duct, as Al Wick did. I will probably go with a larger radiator, EWP and
fan.   Thanks again.  Paul Conner
