Re: torsens in factory racing quattros

[Dave Eaton <dave.eaton@minedu.govt.nz>]

no, it still torque senses, but always keeping within that bias ratio.  just as
the torsen on all other audi's does.  it's just that the bias ratio and the
static ratio are different (50:50 and 2.3:1 for my ur-q and rs2).

to further emphasise the point, it is impossible for a torsen to send 0% torque
to a shaft as this is outside it's bias ratio.  it will never send less than
the bias ratio (30% in my case).
