I have the 98, 95, 85, 80, and 75 on the car. My predictions are as follows plus 3% for having a manual transmission). I think @Laynlo is trying to temper expectations.
98 - 5psi on stock internals and exhaust (A8 530whp - M6 550whp)
95 - 7psi on stock internals and exhaust (A8 550whp - M6 580whp* fuel limitations on 93)
85 - 8.5psi e70 after cam and headers (A8 700 whp - M6 730whp)
80 - 10 psi e70 after cam and headers (A8 730 whp - M6 760whp)
75 - 12 psi e70 after cam and headers (A8 761 whp - M6 787whp).
The belt for the 80 and 75 was a 080845.
I believe the belt for the 85 was 080842.
Hope that helps. I need to go around and see if I can find the pulleys. I should sell them for half price.
FYI - I waited until Ted was available to hit the dyno and called him. That way I could log the runs and make the changes he wanted to see. We used it as a tool to confirm what we were seeing on the street and the last run went to about 185mph (that was a scary proposition).
