Ah-h-h; had you considered the use of a
water manometerJ?
Al
It was not connected to an under cowl probe (my bad) but I had a better instrument than a water manometer (a custom version of the EM2 with a low air pressure readout) but there were other factors. Oil temps right at redline are distracting to me while trying to gather data. The under cowl temps were so high that the alternator was dropping the regulated voltage. The coil temps were close to the point where failure occurs. After landing, the temps went high enough that the coils started misfiring at anything over 2300 rpm. I wanted a test environment without so much stress.
Everything was so nice with the cowl off that I flew for about 45 minutes while the EM2 auto programmed the EC2 map table.

Time is limited before I leave on vacation and I really needed to know the
answer before I do. So, last night I made the decision to fly the -8 one
more time - This time Without the cowl on. Secured anything that might
get blown loose with tie wraps and did the deed. Whoo Hoo!
