993 goes unh unh unh
OK, this is not as weird as it sounds.
My track car (1995 993) has a new Porsche Motorsports LSD; about 12 track days on it so far.
In turns, the rear end of the car is making this obvious noise that is related to the speed of the car and perhaps the cornering force (it is hard to measure this as the sound is likely being heard reflecting off of tire walls, etc).
I think it is equal in both left and right corners, but again, tough to tell.
No sign of the noise on the straights or at paddock speeds.
Just back from 3 days at Mont Tremblant, and the sound was getting louder each day, but then, I was getting faster as the event went on.
Is it possible that this is the sound of the diff working and I shouldn't worry about it?
I would love to get some feedback here; am cross posting to 993list as well.
TIA

After a good long talk with Steve Weiner and my mechanic (Paul Tosi), we have concluded that this is normal sound for a PMS Limited Slip Diff (they come from the factory 'tight' and so tend to be noisey).
Whew - I was worried about major expense.
Steve was absolutely terrific in helping me with this (as is Paul). Thanks, Steve!
