Chris, do you have a listing of all the HP data from your dyno run? It only shows 8900-10000...

I'll offer up another stock motor dyno chart....from my bike. :)

http://www.burgiracing.com/pics/ChrisSVDynoChart.jpg  - This one is in MPH
and HP
http://www.burgiracing.com/pics/chris-sv-dyno.jpg  - This is in spreadsheet
style.  First column is RPM.  Second column is HP.  Third column is torque.
The next two columns are in a different way of calculating these numbers.

This was done on a SuperFlow dyno last February with 87 Chevron gas with 13k
street miles on the bike.  Around here that means it has 10% ethonal.

As you can see I don't gain much HP after 9k RPM but enough for me to just
keep the hammer down until I see myself getting close to 10k.
