Greg,
The airplane should go much faster than that. These airplanes slow waaaay down with drag. If you raise the flaps to reflex position (7 deg up) and raise the gear I would expect to see 140 kts. They creep up to max speed especially with light power so get it up to cruise and trim it out.
I have not heard much about the IVO propeller however. A few unflattering coments but that is it.You may do better to put on a quality fixed pitch. If you are looking to change the performance drastically, go with a bigger engine like a 0235 with an MT 3 Blade. Both will set you back but would be huge performance options.

I'd try just the right fixed pitch propeller and just fly it....

A close friend has a pristine Lancair 200 that he has asked me to fly and then render opinion on the aircraft's performance.  It looks great and has obvious excellent workmanship in its construction.  After a thorough annual condition inspection, I flew it and found that it was seriously lacking in power.  In fact, with just 10 degrees of flaps and gear extended, it never accelerated beyond 60 knots  (though it was simultaneously rising at about 400 ft per minute).  I didn't immediately retract the gear because I was concerned that the plane was flying just above stall.  In the traffic pattern, I retracted the gear and got just 78 knots - still with 10 degrees flap.  I landed uneventfully.  There was no abnormal balance or control of the airplane and, in fact, its construction symmetry is nearly perfect.  Jack test of the landing gear showed completely flush retract of gear and doors - not likely that something was dragging.  This plane has an 0200 engine with 9 to 1 pistons producing some extra horsepower; perhaps a total of 115.  Its prop is a light weight (27 lbs) cockpit adjustable, electric IVOPROP.
 
Does performance sound right for such an early version aircraft?  Who has had experience in these underpowered planes?  What performance numbers should we be seeing?  Without more power and speed, I would be reluctant to take on a passenger for flight.   Greg Nelson
