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]

you should climb at full power,there is no way to overbooset a lycoming 360, it does not have a turbo, mine lAST ME 2000 HOURS W/NO PROBLEM I always climb at full power available, I also had the electronic ignition,
when overhall it looked like new, I change the oil every 25 hours.
It is recommended that you do not run a manifold pressure number higher than the rpm on that engine. For instance if you have 2500 rpm you should not exceed 25". If you want to run 2400 rpm you should pull the MP below 24" before doing so. It isn't over-pressure they are worried about, it is the amount of torque being put on the crank. You will have a hard time getting 27" out of that engine at full throttle, so you do not need to worry at full throttle.
