[Biturbos4] Turbos Reliability & Replacement Cost (was: 2000 S4

[Henry Nisiewicz]

Hardly.
Besides the B5 RS4 had 380 hp.

Looking at the 2000-1 Audi comparisons:

1999 B5 A4 sedan 2.8l V-6 Quattro, 190hp, 5-spd manual, 3220#, 0-60 = 7.1
sec, QM = 15.5s @ 90.5mph.  Source: Road & Track Feb, 1999.
2000 B5 S4 sedab 2.7l bt V-6, "250" hp, 6-spd manual, 3585#, 0-60 = 5.5
sec, QM = 14.1s @ 98.3 mph.  Source: Road and Track Oct 1999.  This with
'only' 60 hp more.
2000 B5 RS4 avant, 2.7l bt V-6, 380hp, 6-spd manual, 3435#, 0-60 = 4.9 sec.
QM = n/a.  Source S-Cars.org Audi RS-4 Avant technical specifications.  130
hp more and such small improvement in acceleration?

I recognize the performance/hp curves will not be linear.  

You can talk about dyno reading, torque curves etc. all you want, and they
certainly have their validity.  But explain the above.

Then look at the performances of other 2000-2003 sport sedans with less
weight and more hp, and slower accelerations.

Some examples:

2001 Acura 3.2 Cl Type S,  260 hp, about 3200#, 0-60 = 6.7 sec (R & T
summary)
2001 Volvo S60 T5, 247 hp, about 3200#, 0-60 = 6.6 sec, (same source)., and
so on.

Remember, I did not say definitively the B-5 S4 has 300 hp, but I certainly
have reason to either suspect it has considerably more than 250 (or 265),
or many other numbers are very suspect.
