9000rpm. Is it for real?

Reminds me of Spinal Tap... 11... These Go to 11

Technically revving beyond the power peak is to keep you at the maximum possible power at every instant, regardless of gear. Would you rather be putting out 450 hp at 8800 RPM in 2nd or say 400 hp at 7500 RPM? If you shift early, you're leaving power on the table.
Because the RS is RPM-limited due to piston speed, it's going to use much of its extra power just to make up for that RPM reduction compared to the GT3.

I do understand idea of revving beyond the peak power to get in the power band in the following gear. The point is that the car in Auto mode never revs to 9000rpm but only to 8800rpm. At least mine.
You still can notice that in the first gear. At second and third it is somehow quite noticeable. It looks to me that it makes no sense to rev to 9000rpm but to change the gear at 8800rpm like it does in Auto. Then the question is why the red line is set at 9000rpm?
9A1 is a fantastic engine. No question about it. To compare S65 (E9x M3) had a red line at 8400rpm and peak power at 8300rpm and was pulling nicely to the red line. It's not the case in 9A1 I am afraid. Makes no difference to me. The GT3 is still a space shuttle but somehow that little thing puzzles me :/

Are you saying that you can actually notice a drop in hp in between those 200 to 300 rpm?
Personally, it's revving so fast I can't even notice it visually - much less from a butt dyno perspective.
I know what the engineering specs say and the charts show, but actually noticing a perceivable difference? Never.
Maybe I just need to pay more attention at my tach and stop looking at the road.

For example, here is 1M curve
- redline (7k) power is less than 5000rpm power - typical for turbo engines. But the entire rev range is useful and is there for a reason.
So it does not really matter.
