I'm flying on a PA-28R-200 with a Lycoming IO-360-C1C engine.
I would like to know if it exists a RPM setting which will not overboost the engine while climbing for Best rate of climb speed.
People are using 25 MAP and 2500 RPM but I cannot find the answer in the flight manual.
On marchetti, you can use 2500RPM/Full MAP for example.
I also have a PA28R-200. I have always climbed at full throttle and 2500 RPM, above 35oo feet I slowly start to lean until I'm indicating 10gph. Cruise flight above 5k, full throttle 2400RPM and 8gph. See John Deakin's article on climb power. [www.avweb.com]

Joe, per the original Airplane Flight Manual that came with your plane the Lycoming IO-360-C1C engine limit for all operations is 2700 RPM, 200 HP. The Lycoming Operator's Manual states the same thing. There are no restictions for operating the engine at 2700 RPM. There is a limit of a Max Cylinder temp of 500 deg F. But that's it. If your tach is accurate, your prop governor adjusted properly and you are operating at or below 2700 RPM you will not overboost you engine. John Deakin has many good articles in Pelican's Pearch, particularly #63 through #66. [www.avweb.com]
