Default Re: What kind of performance #'s are YOU seeing?

Installed PF with Jaguar Cowling and am seeing fantastic performance. Same 63 in prop, climb up by 300+ Ft at all altitudes, lift off much shorter, no pause before climb as before, Cruise with new Cowling up 6 kts at lower altitudes, up over 10 kts above 6000 ft. Thanks to new cowling CHT temps down from 380-420 to 360-380 at same power numbers. Fuel flow with fine wire plugs down from 10.9-11.0 at most altitudes, to keep clyinders cool to 9.4-9.9 depending on power settings able to lean to engine quit and CHTs stay same unlike before when temps would climb to redline at same lean numbers.
1976 AA5-B Tiger using JPI 730 for all readings
Best upgrade investment I have seen, more speed+less fuel+cooler engine=great combination.
