[s-cars] Question about compression ratios and tuning - More 20vt

[QSHIPQ at aol.com]

According to my library of audi documentation, all 20vt I5 production cars 
(save the SQ at 8.0:1) carried the same static CR of 9.3:1.  Double cking, I see 
no references to the contrary on any of the motors discussed in this thread.

ADU (RS2) - 9.3:1 
AAN  (URS4/6) - 9.3:1 
3B - 9.3:1
