[urq] A2 Rally FI

[Brandon Rogers]

all very interesting....I do recall seeing in the videos etc about how a
small item malfunctioned, ausing her to DNF...and man those turbo k-cars
kick arse.

So to expand on this rally stuff...in terms of homologation , how did Audi
homologate the A2?  I can see how they homologated the alloy block, as
suppposedly there are/were some alloy blocked cars running around, but what
about the body (wider flares, taller spoiler) and what about the smaller
motor (~2109cc vs 2144 cs to give the car a lighter weight requirement)  And
of course - back to EFI - I guess it was legal to change the basic
operation/architecture of the motor setup - as the rally cars had EFI
(obviously unlike production cars) and they aslo had the big FMIC - again
unlike production cars....I guess there was some flexibility built into the
rules....

> It gets worse Brandon.  I remember speaking with Ned back in the early
'90's about my direct experiences with racing and modifying dodge turbos
back in the mid 80's.  Attached to my 12K USD Dodge GLH turbo in 1985 was a
motronic box that didn't come to the audi until 1992 S4.  Although it used a
single coil activation, the GLH turbo had a ten second overboost mode in
stock trim (9psi OB, 7 steady state), knock sensor retard.  Mopar
Performance also delivered a modified box that would hit 14-15psi OB based
on knock only, and a 12psi steady state.  All with NO intercooler and dual
bosch fuel pumps from the factory.

of the A2 using Motronic.  I'm sure based on memory, that Audi was testing
Motronic systems pretty early in the game, since the Audisport Bosch and
Pierburg CIS were plagued with problems from Day 1 of WRC.  I will say too,
that Audisport kept that basic mistrust of fueling systems right thru
motronic EFI systems.  Even the 95 Group A S2 had quick release dual fuel
pumps mounted on a board under the rear hatch, with quick switch capability
of all lines to a fro.

in WRC, it sure seems apparent that CIS was one of (if not) the primary
causes of Audisports rather disappointing results following early commanding
leads.  I go further and propose, you might have even seen Mouton beat Rohrl
for Drivers Championship in '83 if fueling wasn't an issue in the A cars

Blomquist re-visiting some of his past cars - including the quattro A2 ( His
favorite!), SQ, RS200, ...others. Anyway in their mentioned that one of the
changes to the car in A2 form A1 form was the introduction of Motronic. I
found this interesting because I've always wondered why it took Audi so long
to shift production cars to Motronic from CIS. BMW was using Motronic in the
mid 80's. Then recently I read that a Porsche Turbo as late as the 90's
still used CIS ( 1994 3.6 single turbo???)
