Precisely what had me questioning the write-ups I've read, if the Haldex is
attached to the rear axle, how can you get any more than 50% at the rear? The
Haldex would have to be an integral part of the front transaxle, splitting the
torque/power between front and rear like the Torsen does in the Quattro. The
only current application I can see where a Haldex/Gerodisc type application
truly works to split the torque/power where needed is the new Quadra-Trac in
the '99 Jeep Grand Cherokee.

NOW that sounds like a plan!

By the way Dave, you wouldn't happen to be related to the Eaton that
manufactures those wonderful superchargers currently being used by GM on their
3800 SeriesII engines?
