The composite gears were originally developed for use in Winston Cup Engines that use dry sump oiling thus no torque being constantly applied to the gear, it just drives the distributor in that application.
I mentioned this quite a while ago in another thread, I had the opportunity to talk with one of the engineers that was attempting to bring the gears to market (3 years ago or so) he ackowleged at the time they had failures with wet sump applications and at the time they were only approved for use in Dry Sump applications, but they were "Working on it". At the time they were working with Comp Cams to be the Vendor. It remains to be seen if the strength issues are resolved (?). The lack of ZDDP in various oils has something to do with these failures too.
