Waltzing Matilda with Torsens

Or we could look at a formula and plug in knowns, and explain Tshift with just
numbers.  A center torsen, by design (that's physics) senses and distributes
torque.  In the case of most center torsens, including your own car phil, that
is defined as 78/22/22/78.  Take Trg * Gear Ratio and plug it in you get
Tshift.  THAT is the physics of the design.  I can look at a LOT of Tshift,
and say you have a fwd rwd fwd character in the same turn.  Easily explains
bite potential.  Doesn't EVER, NEVER happen in an Urq or RS2?  Hmmm, well the
PHYSICS doesn't change, only some variables.  Still easily explains my
experience AND yours.

"Told" me or haven't experienced it?  People tell me that pigs can fly (or in
this case not).  You, Dave and every other Torsen Center car has Tshift,
significant, in every gear.  I've had it happen in a lowly 90q sedan, short
wheelbase and all.  So, this rinky dinky physicist agrees that you haven't
experienced yet, have a little trouble with the "it flat doesn't happen".
Tshift happens.  A lot of variables can and do affect when that becomes a
chassis issue.  Also so posted.  However, as cf lowers, so do "exemptions".
Same physics

Please do, always happy to plug and play.
