I have not tried to find the breaking point in an FA. It gets kind of expensive, lol. But I have not seen excessive wear on an FA from just a LWFW (yet, you never know).

I have also not used/installed a FA20 LWFW at less than 14lbs (yet).
So what you are saying is that by running the stock pulley with the Lightened Flywheel there is no problem with the engine damaging the bearings.

But with a light weight (billet) pulley and a lightened flywheel the bearings can be damaged.

I wonder what the stock pulley has that the lightened pulley does not.
