Steve--I have a Superior 360XP in my 360-N471LA.  I have the 185 HP with the  9:1--my son built my exhaust system and we believe that the engine is now displacing 210 to 220 hp.  I have an Aerocomposit 3 blade prop--My cruse at 2000' is 185 knots at 21/25--6500' I see 210 knots at 22/25 and at 8500' I have seen 230 knots at 22.5/25.  I now have 65 hours on the plane---the only problems I have had was oil temp---resolved with a seperate naca scoop--cylinder 2 and 3 heating up on climb out-445--had to have the injection system flow on take off increased 3 times--I am about to have it increased for the 4th time.  I am very happy with my plane and my fuel burn is between 9.3 and 10.2 with egt of 1320-1390
