Ernest,

Air comes in the back of the radiators and makes a 360 turn. Not suppose
to work but it does.=20

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.
