Alibaba - Custom Billet Crank Shaft for S65 V8

So who dares to order one of these and try it out?




This one does say 75.2mm stroke (same as stock stroke):
https://www.alibaba.com/product-deta...6166169eq2TK97

Technical Features:
• Engineered specifically for high-stress racing applications
• Nitrided and shot peened for improved strength and bearing life
• Large fillet radii for improved strength
• Straight hole oiling system for improved lubrication
• Journal tolerances held to +/-0.015mm
• Fully Counter Weighted
• The grain structure is not stretched or deformed
• 100% CNC-machined by five-axis simultaneous CNC

This one says 94mm, not sure if that is the stroke?, it doesn't specify what the 94mm is:
https://www.alibaba.com/product-deta...cdbd17d0SNOv4C



It says: Billet 4340 Steel

This one says E90 M3 CRT E92 M3 GTS crank no stroke listed.
https://www.alibaba.com/product-deta...cdbd17d0qJIS5d

They also have connecting rods:

The pictures don't show S65 cranks. They don't have to...but they should. If there were a 94mm stroke crank, it would swing outside of the block. The largest stroke you can go is about 85mm.

I'll order one for science, if you'll buy Bert's spare flat plane crank for S65.
