I am sending the Crankshaft to Stork Laboraories to have a metallurgical study done on it's composition.. This will occur as soon as we get all the dimensions from it necessary to complete the new billet crank.
I feel the crank was not the determining factor, the imbalance it was absorbing surely made a big difference in the mode of failure.
None of this will happen again as I will be balancing and indexing the LWFW as well as the DMFW to two new pressure plates and will introduce noth of these when the engine's rotating mass hits my CN balancer as a new assembly.
Balance is critical, especially at high revs on the track under constant acceleration.
