 I chose Fast and Cheap.
 
 
 
 
 
 Me too.  Several asked about my final engine selection.  Being retired
 and pinching pennies in a flat land, I just ordered a Performance
 Engines IO-550 EXP, normally aspirated, 370 HP.  I don' plan to use all
 that horsepower.  But I will be able to get 80% of 310 HP (a legal
 cruise power setting for the IO-550 in Columbia) at 12,000 feet yielding
 about 245 knots, according to my computer. Or get 65% at about 16,000
 feet which yields about 235 knots at 13 gallons per hour, a nice number
 when avgas is expensive.  Testing will see if I am right or wrong.

 PS the 65% fuel flow number is 50F lean of peak, also legal in Columbia
 IO-550 when at or below 65% of 310 HP.
