Hello there, friend. I, for one, enjoy reading your posts... I find the info to be well-thought-out, and usually intriguing stuff that hasn't/wasn't raised before.
For example, I thought you made an excellent point about the shearing forces constantly being applied to the six alloy hex screws (which, although they can handle them so far, they're not really designed/engineered to handle them optimally). So, your observation got me thinking... if the center section and outer pulley ring were splined on their mating surfaces, the screws wouldn't be handling those forces. Alternatively, stronger fasteners might be procured from a vendor like ARP, for longevity and peace of mind.
Might be an R&D improvement that LET incorporates into their V2, V3, V4, etc. crank pulley - or maybe not, but at least the info's out there - you know?
FWIW, people can choose what they want to read - if they think a post isn't applicable or too lengthy, they can skim or skip it. IMHO, if a post has substance to it (and usually a few good gems of info), I enjoy the opportunity to expand my knowledge base with said info.
That's why I read Woody's novellas...
