Engine RPM and load

[patterndude at comcast.net]

I don't have much to chime in about. The engine is very happy between 7900 and 8300 (the ranges I run on the high end).  I don't have any experience propping down to 6800 and would worry about over heating, but I can't comment with accuracy.  
  Wayne's numbers are pretty common on the 170.  I would expect a 17x12 regular to turn between 8100 and 8300.  My 17x12 regular turns 8150 and teh 15.75x11x3 turns the exact same.  If you're not getting this, but the engine runs fine, then maybe the pipe/header are choking.  I have no experience to compare the 590r to the other pipes.
