We both would get a nominal 5200 rpm static (on cold mornings due to the EDDIE effect my static would go as high as 5600-5800 rpm).    In my 120 mph (TAS) WOT climbout I normally would get from 5600-5800 (depending on OAT).  So if you are not getting at least 5000 static, you have some tuning to do. 
 
Thanks for the extra data.  So you figure that your 5200 rpm static is WITHOUT the benefit of the EDDIE effect?  Now I'm really depressed.  I'm getting 4700 static, and 4900 in climb at 120 mph.  
 
IIRC, in a previous message, you mentioned that there were two general paths of intake design, one being low restriction to mass flow, and the other being tuned effect.  Mine is likely neither, so at least going to a short intake could buy me something.  At the moment, I'd be happy to get up to your non-EDDIE static rpm.  
 
Hey Paul.  You have an identical intake to mine.  Have you been able to do any full power runups?  With what prop?  What RPM?
 
Thanks,
Rusty (maybe NOS)
