Re: Torsen bites Performance Car

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

errr, no.  scott states that the torsen bite can affect a car when in high cf
conditions (dry tarmac), not low cf (snow, ice).  in the pc article, the torsen
is doing exactly what it is designed to do.  shifting torque at tmax (ie. 70%
of torque) on dry tarmac is what is called the spider bite.

i don't have any doubt that the locked centre could be better in low cf
conditions because the tshift is 50% of torque, while with the torsen, this can
be 70%.
