(Side note, the CHT on #4 shows lower due to sensor placement; manual temp measurement shows that cylinder has a similar heat profile to the others.)
50% resulted in a 105mph airspeed. Are there any potential hazards to reducing further to get 90mph? I can get to 90 in the pattern with full prop and manifold back to about 10-12, but have never tested running that way over an extended period of time.
