I've never worn out a set yet.   I am not at all surprised there was some abnormal wear on Davids dampers since the flex plate was literally falling apart.

But this is experimental and we all have to make the final call for our own installations.

I finally took the new flywheel and silicone dampers out for a flight today.  I was hoping for a slight improvement in idle and/or smoothness with the little bit of extra weight in the flywheel, but I guess 4 lbs is just not enough to make much of a difference.  I flew around for about an hour and got the RPM up to 7000 and MAP up to 40 in., and loading the plane to 4G (thinking about gyroscopic forces) without any noticeable change in the way the engine sounded or ran.  Everything look ship-shape on a post-flight examination.

This is the ACT flywheel that Kelly found for us.  Looks bulletproof compared to a flex plate.

Next project, finish installing the ADI system.
