I've listen to Mike Busch on the EAA webinar and he runs his engine WOT and LOP all the time. His argument is at WOT he gets the maximum volumetric efficiency from his engines. He just has to made sure all of his CHTs are no higher than 380degF and his engine went way past TBO.

Sorry for divergent from the original post.

I am a Lycoming man.... (Continental if I have to).

Every new engine is the best, latest and "modern". The only "new engine" to catch on in USA market in decades is Rotax, due to FAA adding Light Sport category. Many LSA designs came from Europe with Rotax; even RV-12 is based on the Rotax. There was/is a lack of 100-120 HP engines except for the Continental (I)O-200. Rotax is not cheap. A new Rotax 915is (140 HP) is $36,995. That is more than a Lycoming.

I would love to see new engines like this, direct drive and air-cooled take on the Austria Rotax geared high Rev water cooled engines.
