there are some supporting numbers which indicate a return on TBO, then

Just some fun numbers for food for thought.

Ok, it may take two years to get your investment back in money saved
from fuel not burned.

And that's just fuel; it doesn't even take into account wear and tear
due to higher CHT temps.

This is what I was hinting at. Does anyone know of any studies which can
associate an engine monitor with engine reliability, longevity, or reduced
TBO costs? Running engines past TBO?

I agree, common sense says, we'll see a happier engine resulting from
better managed temps, but is there anything that supports what a "happier
engine" translates into?
