I've run the SCAT 9000 cast to 649HP and no issues. I remember eavesdropping on Jon Kaase and he was saying that a cast crank will make more HP than forged because they are stiffer--he's right. The trick is staying below the failure limit. J.Rob
RAMM I think a good balance job really adds longevity to a high hp cast crank build . what you say about stiffness of the cast crank is very interesting maybe that's why they snap when they reach their limit they don't flex to absorb the stress or am I over thinking this
