Paul, Along with the center main bearing we have discussed the high oil pressure required for high rpm operation. There was something of a call for the center feed oil system. I have a design
started for such a system. Would this really help or is it something of the latest answer to a question nobody asked?  If there really is a call for such a thing I'll continue. What do you think?

The road racers are interested. I expect the drag racers are also interested.
To all our aircraft people you can ignore this thread as aircraft use never
gets anywhere near 10,000 RPM.
