We tried everything to get a 5.86 and 6.00 gear to live in our car....350 cu in. 993/997 with 615 estimated and around 510 torque... Mark Williams Caps, LPW Cover, Shockproof Red Line Oil.. ( Still have 5 gallon never opened). Set them up Tight...Loose...Deep...Shallow...Took the housing out and had it completely updated with additional bracing @ PK Racecars....
Never made any difference..@ 25 runs it was making noise...And @ 50 they were gone.You might run them close to a hundred, but you were holding your breath.. I think the weight is very crucial. We were @ 3300. We changed classes and went to a 3000 pound and a 5.57 gear and never had any problems . Can run this set up year after year...Those little pinions don't like weight,
