Your not.  My car has approx 215hp to 225hp (untested, guesstimate hp).  It
is running 1.8 bar.  Scott Mo. (Sorry to bring you into this Scott) may know
more definitively.

My car is _not_ a quattro (See signature tag).  Curb weight is 3,000 - 3,100
lbs, similar, I believe, to an Urq.  Straight line acceleration at higher
speeds should be similar (off the line is probably different.  I would
expect the Urq to stuff my car off the line  Better weight transfer, no
smoking front tires).  I base this on similar weight, same basic motor and
turbo, similar hp, etc.

Good point.  I didn't think about that.  However, I _did_ think about a) and
b) before posting, so the ready replies are above.  But since we brought up
a) & b) anyway, why don't we investigate c) as well...  Is the gearing in
your MB Urq different than the US 86 turbo 5 speed?  I believe the gearing
is the same in my car as a 5000tq.

Sounds like fun...
