Hi Dan
My feeling is that racing only shows us week features of a specific design faster than we might see under normal use. In other words " a weak design is weak whether you stress it or not."
It appears to me that the webs at the through bolt holes are too thin.
Possible stresses not see in other Porsches are excess vibration from a crank imbalance exacerbated by the removal of the harmonic balancer and dual mass flywheel, too much low end torque, too much twisting in the crank? Who knows?
