When I was talking with Guy a few days ago, he mentioned that during
durability and gyro testing that the bolts that hold the bellhousing to
the engine ?work shifted? and he had to go from grade 5 to grade 8
bolts. This was testing done with a standard rotation cs aluminum prop
and over 400hp using his standard bellhousing, so he has worries about
the strength of anything different. He says his bellhousing is cast and
1/8? thick. 
He also mentioned he has designed a belt driven hydraulic conversion of
the Woodward governor (also an outgrowth of his PT6 work) that is being
fabricated by others.
He also says that the oil used in the gearbox has to be cooled before it
enters to get good cs performance.
BTW, if you print out his word doc pamphlet, the 13B prints out oriented
correctly! Don't know why it is that way on the doc when viewed on
screen.
