"I am using gravity feed fuel supply which would be more suseptable to leaning than a constant pressure system."
Thanks Rich for that tid bit of info. This is exactly where I am at today. My run today was great. After Marks great inspection yesterday, I got determined to solve my power problems, so I sat thinking of how to enrich my Revflow without adding a fuel pump. I came to the conclusion that the gas was not coming out of the carb. I reasoned that the straight taper cut of the revflow needle was not going to feed the engine at WOT and at idle/midrange. I decided to create a WOT step down over the last half an inch or so. I went to the hanger early 8AM and ground the step and put it back in the Revflow. Presto, 3500 RPM and 40 MP. Though I have tremendous power now, I feel that the engine is at minimum running Peek EGT, and not rich of peek as I would like to see. Well, 3500 and 40 is more then I want static and now I can finally use some of the variable pitch in the IVO prop. Before I repitch the prop, I need to know if any one with a turbo with a controllable waste gate is making enough power to need the gate and what will happen as the altitude goes up. Tomorrow it's back to fixing the things on the list and trying to find a good vernier cable locally. Orma Southfield, MI N110LR celebrating 20 years To the gathering with the KR or bust
