I really need to run it on a dyno to look at the graph. But from driving it, the power seems to peak a bit over 6000, with 6300 being a good shift point. It'll easily pull 6500+, but the power has definitely started falling off by that point. Those RPM's are according to the tach, though, so I don't know how accurate they are. Those #'s are with the cutout open; closing the cutout seems to drop those RPMs a little bit.

Like I said, though, I need to get to a dyno so I can have some useable #'s.

 

Boy, that thing must just be a monster down low!!!

 

Yep!
