Dave said, My 'wide open' flying RPM is around 34-3500 if I remember right
Most engine failures, usually valves, on VW's are due to heat. You may have really excellent cooling with your engine and if so maybe you can get away with those RPM's over time. Make sure you have a very accurate oil temp gauge. In my experience I'd limit RPM to 3200 continuous cruise. Steve Bennett, from whom I bought my Great Plains 2180, used to cruise his engines at 2900. Pretty conservative, but if you want long life and dependable operation from these VW's, being conservative isn't a bad idea. By using a coarsly pitched prop (I use a 52 x 56 Sterba and run full throttle at altitude - above 8K) you can extract power without using so much RPM which generates a ton of wasted energy - internal friction (heat).
