Hi folks.
Up to this day, I've been under the impression that one schould never operate a Lyc on "over-square" powersettings. In other words; MAP schould never be set to more than the actual RPM.
For example 23/2300 or 21/2300 and so on.
Today, a few guys in my local aeroclub discussed this and a couple of the guys said there was no problem to operate at over-square powersettings.
On a T&G for example, one could set the RPM at 2500 on downwind and use full throttle on the T&G. That would give around 27/2500 I guess.
One mentioned that in his old days, they used 2300 RPM and 36 MAP on the Harvard.
I want to know the facts here, so this question is hereby sent out to all you engine-guru's out there....
I'm standing by...
