Ernest,

I posted pics of the inlet and outlet earlier. I just sent them to you
directly as well.  Bobby

  

I can't really tell, Bobby, but if the air exits the radiator only to hit the firewall and be forced to make a sharp 90 degree turn to continue past the airplane, then the 'effective' size of your outlet will be much smaller than the effective size.  The bottom of the firewall should have a nice radius to help the air turn and continue back, instead of blowing straight down and getting in the way of other air molecules that are trying to make their way out the exit.
