But officer, I was only testing the car's capabilities on a private test track...Ex S2 owner, now running around in an A4 Avant quattro...

Aero is the big pain in one's bottom for high-speed car design - look at the amount of aero trickery Audi had to come up with to get the Veyron to work at those >200mph speeds.
I would guess yes the nose would get much lighter at those speeds - the Coupe at least has that big wing on the back which must cause some positive aero at high speed, even if it is a very inefficient design. There is no deliberate under-car aero in the S2 either.Ex S2 owner, now running around in an A4 Avant quattro...

Yep, thing is, when I did pop round - there was a shed load of officers + 'safety' camera's round the corner.... just as well I'm the sort of S2 driver who can get 371miles out a tankful1997 A6 (C4)Q TDi http://forums.tdiclub.com/showthread.php?t=291269 - Sold

If anyone fancies a top speed run I will let you try in the S2
Sod 202mph. If anyone says that feels ok then they are mad!
The difference between 150 and 100 is huge, imagine the same jump to 200!sigpic

I'm reminded again (sorry to keep banging on about the Veyron, but it's worth repeating) of the Veyron Top Speed feature on Top Gear recently. Clarkson was harping on about how pretty much every car ever made so far feels and sounds like a bag of spanners that's about to split in the ~200mph bracket because of the aero battering they get. They then went on to say said that the only car that felt easonable at that speed was the Veyron because of all the aero work, and the fact that it was engineered to go smoothly at 252mph...Ex S2 owner, now running around in an A4 Avant quattro...

as jamo said - the lag and lack of off boost power of the super low compression was too much. I don;t like the sound of solid lifters.
You have to go a step too far to appreciate the previous level of power/lag
the car ran too much boost on the dyno - 34psi - it is supposed to do 30psi - it still made the same power but on a recent top speed event at RAF Marham I only did 178mph - but it would get upto 160 really quick then go flat - probably because it went into the knock map from running too much boost. I did do 28 top speed runs - I got my monies worth. It was the most fun I have had at a top speed event - for just getting the thing launched and keeping it straight in lower gears. I took all the b5/b7 guys out and they couldn't stop laughing. The next day driving into the workshop the rear diff exploded - glad i didn't do that on the pristine active runway.S2,RS2,S4 WB,RS4,S4 B8,RS6 C5,RS6 C6,R8
