Good idea.  Suspect you are right about the boundary layer being
distrubed.  Being as Tracy, Jim and Neil do not employ louvers and
apparently have no problems with under the cowl heat would indicate they
are not needed.  I think I will tape over the louvers with some duct
tape on the inside take the exit ducts off the radiators and give it a
try.  Orginally had it set up without louvers, but on hot day ground
runup would cause the temps to climb.  But, as you have suggested in the
past, cowl flaps may be the answer for ground runup cooling.

Great thing about a project like this is you never run out of things to
try or do.  But, I think my next priority is to do something about my
intake manifold to see if I can get a few more HP.  Last 1 1/2 inches of
throttle travel which open the throttle body wide open does not generate
anymore rpm.  So suspect that my intake manifold may be choked at
85%-90% throttle opening with no increase in airflow. Paul Yaw has
indicated as much also.

Well, the snow is continuing to fall and traffic is at a standstill
outside my office here in Northern Va, so looks like a long day at the
office.  Now if I were snowed in at the hangar it would be different.

One thing about the North East one never has time to get depressed over
the meaning of life :-) A little snow shoveling makes one appreciate
the good times more :-)
