It's done but not
finished. First flight today for about 20 minutes around the airport. I
still have a few odd tuning issues but Tracy believes it due to my MT electric
prop and provided a different approach to try. My supercharger was mostly
bypassed for this flight so MP pressure never got above 28". Take off rpm
was at 6500 with the prop set for 2250. It flew like a 190 hp
RV-10. About 800 fpm climb. I didn't push it and limited speed to about 110 mph.
Fuel MAP needs to be much better before using the supercharger or increasing the
prop \ engine rpm. I can run 34" MP at 7200 rpm and 36" at lower rpms.
Still HP to be tapped.
A few data points.
Engine was warm before takeoff because of a few high power
run.
Takeoff roll
Oil and Water both at 191 F.
800
agl Oil 207 Water 196
Pattern

OAT

Gearbox oil exit 235
at the warmest.
Looks like I need to
seal my air ducts. They are a slip fit now and most likely not holding
pressure.
Thanks to everyone

support. Special gratitude to the Austin Rotary Bunch. Mark S., Dennis H.
