I am trying to dial in a new motor. IO540 with 9.5 to 1 pistons, RSA10 servo, Raven CAI. I have problems with rising EGT’s at lower power settings. I have exhausted options looking for induction leaks. I am starting to think I am flowing to much fuel. FF on takeoff is about 29 GPH however with the current weather and temps in the SE density altitude is above 3000 at my home airport. The interesting thing is that when I get the rising EGT’s pulling power turning base leaning the mixture from full rich corrects the EGT’s and they come right down. Is it possible I am so rich that fuel is burning in the exhaust creating the high EGT’s?
Is 29 GPH to high for a 3000 foot plus DA on my engine configuration for takeoff? I have searched the forums and can’t find a takeoff FF chart for a 3000 foot DA. Any advice appreciated!
