I bought an awesome IV-P with belly scoop, AC, extended fuel (106 gal) and Electric deice.  3550 pounds gross weight full fuel and bags (1050 pounds of fuel and stuff).  Completely stock TSIO 550E (350 hp) with new hartzell scimitar 3 blade prop.

I could do 230-235 KTAS on 18gph LOP 34" MAP and 2500 rpm, 19,000'

Then I had the deice system taken off (long story), and now I can do 245-250 same setup.

I am now planning to mod the AC system to one with no drag ( tail setup), and hoping to get another 10 knots or more....

Lastly, I know mine is one of the slower IV-Ps out there.

I fly routinely 1100 miles non stop on a tank of gas from Phoenix to St Louis.  Tough to do that with a turbine.

Good luck
