[s-cars] To RS2 or Not? (longish)

Looking at the chart for the RS2 I see where you got the numbers... but they
don't make sense! HP and Torque have a linear mathematical relationship.
HP/RPM*5250=Torque so 200HP/3500*5250=300 not 260! I'm also very surprised
max HP is at less than 5000 rpm. Makes me wonder about the dyno session. If
you spend that much of your time under 3200 rpm I'd give consideration to
Bob's LT1 option :-)

To RS2 or not to RS2, that is the question. . . .
Over the course of the past few years I've been carefully upgrading my
'91 200 20v tqa so it would be ready for an RS2 conversion. Among other
things, I did the suspension; the brakes, added a custom mandrel bent
exhaust, and the IA Stage III+ ECU. I've also contacted a good friend
in the fatherland and have obtained fantastic RS2 pricing. Now that
order day is upon me, I'm having second thoughts. Why? 95% of the time
I live between 2200 and 3200 rpm. I did a bit of charting this weekend
using Jeremy Williams IA Chipped '91 200 TQ Dynograph that's posted on
the S-Car list Yahoo site (files/jeremy_audi.jpg) and RS2 Dynograph
that's also on the S-Car list Yahoo site ( Photos/RS2-UrS4 DynaPack)
From these two graphs, here's what I've *estimated*
Torque conclusion: the K24 hammers the RS2 until about 3500, then the
contest is over.
HP conclusion: the K24 hammers the RS2 until about 3500, then the
contest is over.
Query: Is it fair to say that the K24 outperforms the RS2 until
3500rpm? If so, I'm not sure I want to RS2. Number don't always tell
the whole story, so I'm looking for lots of input from you RS2 guys.
TIA for your help and collective wisdom,
