Did you notice the two cutouts in each of the crank webs which provide access to the big end journals? This suggests the titanium crankshaft was made as a bolted assembly, probably with Hirth couplings and big end sleeves over the joint.

Hi Dave,

Go back to posts 138 and 139 and you can clearly see the difference between the one piece steel crankshaft and the eight ??? piece bolted titanium crankshaft. I believe the steel crank was for the Le Mans cars and the titanium crankshaft was developed specially for the overpowered CanAm monsters. Porsche aren't telling.
