Message P.S to Rusty. You said a good street port would develop about the same power as a good p port at our rpms. Sorry but this is simply not true.
 
Hi Jerry,
 
What I actually said was (pasted directly from my previous message):
 
"There's also considerable doubt whether a good PP engine can actually out produce a good side port (ported REW housings) engine in the rpm's we're running.  I'd be willing to bet that the side port will be more civilized across the rpm range too."
 
As you may recall, I was all fired up to do a PP for the single rotor project, mostly because the intake would be a single tube, and simple to make.  The more I looked into it, the more I came to believe that there was no real advantage to PP at the RPM's we're running.  I now have new REW housings in the garage, which will become the single rotor engine. 
 
I'll be happy to see you prove me wrong, and I REALLY DO mean that!  Now that I have the Sonerai, I'll be needing another single rotor at some point, and I'm still interested in PP.  How long do you figure it will be before you get your current engine running?
 
Cheers,
Rusty (just keeping the conversation lively)
