I just had to overhaul my o-320. It had pretty severe inlet cam wear which impacts 2 of the 4 cylinders. I measured that it lost 0.15 inches. It felt very low on takeoff performance, and highish fuel burn (9.5 vs 8).

What would you estimate my power loss would have been?

Took off from a relatively long backcountry strip and was flying down the canyon for quite awhile.
