I have another update for today. I just ordered the prop for the new engine. I called and talked to Craig Catto from Catto propellers and he has a new generation of three blade props coming out that has some significant low end improvements and a slight top end improvement in performance. It has not been announced yet but since I wont need it until next year he is putting me down for the new version. He also mentioned that they have an option to match a Van's spinner to the prop and have it drilled correctly. I think that will be a must when the time comes.
He also mentioned a couple of items I will need. Either a 2.25 inch or a 4 inch prop extension and he suggested ordering it from Sam Tillman at Saber Manufacturing. Finally he mentioned a guy who owns a 9a with a similar configuration that is testing the new prop. I'm not going to post the name but I am going to do a little research and talk to him about the prop/engine combination.
