Looking for input from those who've run an 8.8 in previous years' high horsepower cars: Was gear noise a problem? I've never pushed more than 400hp/torque before, and only have personal experience, but don't recall ever having an issue with gear noise. What is your experience? Please chime in with other cars you've had, horsepower/torque ratings, that ran an 8.8, and whether or not you had issues with gear noise? I have a theory, and would like to see if others' experience supports it: I suspect, based on my last two tear downs, that the problem with the rear end in our cars is related to the larger pinion bearing. Prior to the 13s, I'm not familiar with any other car that ran that pinion bearing. From what I gather, the FRPP aftermarket axle isn't running the larger bearing, and I'm thinking about swapping the whole assembly, to see if that quiets my noise, unless I've just been lucky in the past. Not looking to build a full-on drag car, just something that I can hit on the street, and not hear the gears singing on road trips.
