There are two different versions of racing quattros being discussed here. Ti
is talking about the 5000/200 series Trans-Am cars which were raced in 1988.
And I think you are talking about the closed course speed record 5000
quattro. There was a small article on this car in the July/August 1986 issue
of VW/Porsche magazine.
On March 24, 1986 Bobby Unser set a new closed-course speed record for
all-wheel-drive vehicles of 206.825mph over the 2.66 mile superspeedway at
Alabama International Motor Speedway in Talladega, Alabama . He was running
up to 216 mph on the straights. The car used was based on a 5000 turbo
quattro production vehicle, but was fairly modified. The body was fitted
with aluminum body panels, front air dam, rear spoiler, lower side sill
extensions, a low drag under-body floorpan, a full roll cage, a racing
suspension which lowered the car and knock-off wheels with racing slicks.
The engine was a specially built turbocharged, air-air intercooled, 20-valve
5 cylinder engine which output 650hp. At the time, it was the most powerful
5 cylinder gasoline automobile engine ever created. The car also used the
standard quattro four-wheel-drive system and five speed transmission. Audi
used this car as the starting point for the Trans-Am racing effort.

Isn't one of these cars is driven by Terry Moss. Do you have any information
on the cars Audi is running in this series? From articles I have seen, Audi
was using what looked like the US Trans-Am cars in that series a few years
ago. Were they known as the Minolta _black_widow_ quattros?
