Out of interest, what do you think you are getting in HP from your 13B and at what RPM?

I would say you have  winner.  Does of course depend on what prop load you were pulling during static run.
 
I have a fixed pitch 74x88 and a well-tuned older 13B and the best I have ever got static - was 6200 rpm on a cold day.  Normally, I get 6000-6100 rpm. 
 
So depending on your prop, it looks like you are doing great for static rpm.

All,
       Looks like I am finally connected after many attempts..  I have a P ported renesis in a glastar that is ready to fly.  Tuning the motor yesterday to find that I cannot get the motor revs over 6300.  I suspected the prop (prince fixed) is too big, but am assured that that is normal as a static load.  Lonnie suggests that once moving the extra revs will appear.  How do I tune the motor for the top end revs?  Any advice?  Neil.
