And, in the grand schemo things, does the 2% mean anything as far as
perfomance, or mean a "spec". Could it be that the rear is a common off the
shelf rear diff part, like from a Bimmer for instance?  Sure.  Comparing 2
part numbers, one in a trans, the other in a diff, seems a bit of a stretch,
to me.  Both take one input and make the same output, don't you think?  You
have more faith than I, that 2% difference was "specified", given the
operation of a torsen.  Betcha 2% can be found in production tolerance right
now.

The bentley makes statements too, so do the owners manuals.  Some say 75%
torsen centers, others say 78% torsen centers.  Same part number.  Makes me
think rounding is more common than you think.  A 60% torsen diff might give
you a major point.  Rounding 78 to 80 or 78 to 75 hardly changes the CONCEPT,
and both appropriate.  Especially considering, that mechanics don't shim,
helix or even service either torsen, only replace it as Fig 1 Torsen
Differential, center or rear.  

Just not with the thinking here dude.  Nor with Dave E.'s that the mysterious
spring effects torsen operation.  To make your point, you would need to
explain how the same center torsen is used in the v8 and the Urq.  Not the v8
center and v8 rear.  They are two different apples.

All this speculation, creates only more confusion

Sorry
