Not sure the first email made it through. I would like to compare the P-Port dyno with supercharger performance at the same rpm between 5200 and 7500. Attached are my HP estimates and they seem to be close to Vans actual performance expectations for a 235hp engine. But I am a little concerned about running the Eaton M62 4th gen this hard. I have not been able to find any data concerning sustained high rpm operations. If the dyno numbers look good I may build a P-Port since it would not require any other changes other than intake. I do plan to eventually put a 3 rotor or 16B p -port in the plane but I'm not ready for another year of building. Time to do some flying and spend time with the family.
 
Thanks  Bobby

Paul,
 
Do you have a dyno chart from your P-Port Renesis test? If so I would like to get a copy. Just about got the RV10 back together after several major changes. Moving the aluminum Berry Mount spacers to the top of the S-Beam almost corrected my thrust line problem. I was also able to remove most of the spacers from the rear beam. Still a little angle on the right side that may require some machine work. It will be interesting to see if it fly's differently.
 
Thanks,
 
Bobby J Hughes
