Does anyone have a power chart for a Mattituck TMX IO360, 180hp engine showing %power for MAP & RPM settings at different altitudes that you could pass along?
Be careful - the original poster seems to have a parallel valve IO-360, but my power chart is for an angle valve IO-360. The relationship of power vs MP and RPM is quite different for those two engines.
What model Lycoming is the closest match to the TMX I/O360?
