Where did i say 1000rpm better response? I didn't.
I said quite clearly - power band. Useable RPM range.
All your dyno sheets tend to end @ 7,000rpm.
Most results you've shown tend to show a drop that usually starts around 6500rpm - a power band of 2500rpm (4000-6500).
If the sheet goes to 7500 (i think i saw one?), the drop was quite big (30-40rwkw IIRC).
To date you've not really answered when questioned about it in 2-3 threads now, and I'm not the only one that keeps asking.
I've not seen a 3071/3076 drop off that harsh ever.
