[QUOTE="Catmonkey, post: 16373735, member: 124025"] I've always understood OGP failures to have to do with unbalanced harmonics at higher rpms. The gears are only driving oil, so I'm not sure they would have that much stress on the initial hit, but that's only speculation on my part. I could see something like a two step or hard rev limiter where you have no and full power in rapid succession beating them up. If you had a big supercharger up top, perhaps you could have snout flex that could put the OPGs in a bind on the initial hit that might lead to that conclusion. It's cheap insurance on a build, but would be a real PITA to go in and just do it. Beside J's failure, who else has had OPGs go south? [/QUOTE]
