pics from the wurth motorsports/bitterman time trials event saturday @ sears point
there were only 3 audis participating in saturday's event...but all 3 were S4s. 
At least 2 other S4 owners were there in their "track" cars, though: Dennis in his Porsche 928 S4 and Frank in his 300ZX (nice meeting you guys & grabbing lunch @ Viansa).
it was a big turn out. i think it's one of the first full-track events, if not the first full-track event, since sears point went into renovations. i heard close to 85 cars showed up (split up into 3 run groups). there were a TON of corvettes there as well as S2000s and like a half-dozen Ferraris.
met jason from new dimensions there (nice meeting ya!)...he had GFB bypass (not the hybrid BOV/BPV) valves in his S4:

From Go Fast Bits...
And I think they're plumback ones, so the noise isn't as pronounced as a valve that is vented to the atmosphere. But since the S4 is a MAF-sensor equipped car, it would run rich and stumble between shifts if it vented to the atmosphere since there would be too much fuel metered when the BOV (CBV) vents.
You can use a hybrid valve that lets some air vent to the atmosphere and sends the rest back to the intake piping... this way you still get the sound and don't have any fuel problems.<ul><li><a href="http://www.gofastbits.com/techspecs.htm#plumback">http://www.gofastbits.com/techspecs.htm#plumback</a</li></ul>
