I've been pouring through these forums for a couple of weeks. Thanks to Ian's hosting the plans I was able to download the Marquart Charger drawings and study them a bit, which is really nice to be able to have those available when deciding what/if I want to build.

From what I could see most Chargers are flying behind some variant of a -320 Lycoming, with an occasional O-300 Continental thrown in for good measure.

I have a core O-360 that I want to use. I would assume somewhere in the intervening 50 years these plans have been out there that someone used the bigger Lycoming at some point. There is a note on the engine mount plans that the 160/180 hp engines would require Dynafocal mounts, so it would appear those engines have been a consideration in the past.

Anyone have any first hand experience of how the airplane flies with more HP?
