FW: Bites of dead horses, last post for me

["Peter Berrevoets" <peterb@mysysltd.com>]

Now you have me really intrigued.

IMO no mechanical system can operate perfectly under all foreseeable (or
unforeseeable for that matter) conditions.  Therefore the torsen will have
an envelope of performance that it cannot exceed.  While under most
conditions the thing works magnificently, I have experienced its peculiar
behaviour when doing things that the general public usually frowns upon.

But the S1 fixed this problem - yes? How?

I recall a video (titled 'Jump' on the net somewhere) showing a Coupe
Quattro negotiating a downhill hard left - off a jump (in the air)  landing
sideways with some hard counter steering and continuing magnificently under
power. No bite there - but that is exactly where it (a torsen anyway) should
have bought it big time!

I'm not an engineer, but it would seem to me that a torsen diff cannot cope
with a power on oversteer situation where the rear wheels are spinning.
Yes/No?

But then, what is the difference between the early Coupe Quattro's ability
to adjust fore and aft torque bias and the later non-adjustable bias
torsens? Does the variable bias of the earlier coupes (type 85s ?) prevent
the free swing of torque front to rear that causes the bite on the type 44's
(and others)?

Just thinking out loud - hope that my ignorance of matters technical has not
put a foot in my mouth.

Uh, oh.  But I don't disagree with the below, just draw a different and
blatently obvious (IMO) conclusion on what was written:
