Bob,
Thanks much for the info.................Just one more question..............Info from "Turbonetics"
says the 1.15 a/r turbine housing is limited to the F1-65 mm or F1-68 mm turbine wheel.......
Do you have info as to what turbine wheel was installed in your 60-1 turbo ??..............
Thanks Again,

Kelly,
I limit my takeoff power to no more than 42 “ of manifold pressure (“MP”), usually just 40” . At altitudes of 5,000 feet and above, I generally run no more than about 36 “ MP (15 GPH) and 180 knots. Engine RPM is about 5,800. The turbo is capable of considerably more boost than this, but I have to watch engine water and oil temps at higher power settings. I do not want to run more than 200 degrees on oil or water and prefer 180 degrees. I can maintain these temps (even on hot days) with cowl flap settings from closed to full open as long as I keep the power settings at or below those described above. One day, I climbed to 11,000 feet and my GPS groundspeed (with a slight tailwind) was 213 knots. MP was 36”, RPM
6,000. I have a 68” diameter x 84 pitch Prince P-tip fixed pitch prop coupled to the RWS 2.17/1 reduction unit.
