For my two cents.  I read on this newsletter that we need about 80 sq.
inches for 200 hp.  Does that ratio hold for 300, or 120 sq. inches inlet.

I raised my inlet from 50 to 80 with great cooling results, yet am still not
pleased at 95F oat.  Mine also look very draggy'.  Something about air speed
through the radiators to make them cool, not just blow through.

Jerry did you seal the area around your PSRU where it sticks through
the cowl? Very important. Also Tracy mentioned at OSH he put a radius 
on his fire wall outlet area and it improved the cooling. Here is a 
good example on a Lancair Tigress with a water cooled Orenda V8.
