I need some info...I don't remember there being an RPM limit on the metal Sensenich prop for an O-320. I noticed in the prop logbook that came with it, a placard to place in view of the pilot, "2600 RPM Limitation". Huh?
Rick of Austin said:Yes that 2600 limit seemed to be an insult because now its not a 160 hp engine/prop combination. At 2600 it is maybe 150hp? I just couldnt see giving up the horsepower when its so hard and expensive to come by.

vlittle said:Actually, Lycoming has different numbers for different O-320 models. The -B amd -D series show about 159.5 HP at 2600 RPM, sea level power. I think Superior's data is similar.
Lycoming's D2J model shows 155 HP at 2600 RPM.
Finally, the reality of the typical RV installation, is that you'll a bit of MAP boost due to ram air affects on the intake. My calibration data shows that this gives about 3-4 HP.
Bottom line? You may actually be seeing more than rated HP.
what signs should you look for If you think you had a over speed of your sensenich fixed pitch prop.what kind of dammage would you see on inspection
Or could there be dammage that is not readily detectable.
The only source of a valid answer to your question is Sensenich. This is a far too critical issue to trust your life to internet fodder.

YEP, I believe it was Abraham Lincoln who first said, "Never believe anything you read on the internet!"
Are you sure??? Were you there.....
