Re: S4/91 200: which is faster?

["Mike" <MikeMilr@email.msn.com>]

As the S4 has used up it's 15 seconds of overboost at the end of the 1/4
mile, I wonder who would be ahead if the competition continued to 125 mph?
Both cars would be in 4th gear at the end of the 1/4 so no more shifting,
But the S4 would be at less than 1.8 boost whilst the 200q can maintain 1.8
boost all day. The close ratio from 4th to 5th doesn't really matter as the
200q will excede 130 mph in 4th at redline. (~19mph/1000rpm * 7150)  - I
assume the S4 will reach top speed (limited) in 4th gear.

I don't have values for 1991 200, but I have the values for >1992 S2, which
