Either way my instructor replaced the prop on his 180 with a nice 3-bladed McCauley.
Comanche 250 cruise speed. I think youd be suprised at just how. Applying all the possible speed mods has brought the cruise speed of a Comanche 180 to over 150 ktas and close to that of a Cirrus SR20 the latter of which has the benefit of composite construction and computer-aided design.

Bendix King Nav Com. In the Comanche 250 itd be even quicker. This gives a four-hour endurance with a very comfortable reserve.
Now even things up a bit by limiting the gross weight of the Comanche 400 to that of the ES then certify the ES then design it in 1963 using slide rulers and paper and pencil. At sea level Garmin Audio Panel. Be an official member.
In 1958 Piper introduced a 250-horsepower 186 kW version using a Lycoming 0-504 engine giving the PA-24-250 Comanche a top cruise speed of 160 kts 185 mph. Most 250s had carbureted Lycoming O-540-AIA5 engines but a small number were fitted out with fuel-injected versions of the same engine. The 65 model was identical to the 250 except in engine power and some Piper buffs consider it the best of the line.
Piper PA-24-250 Comanche - Performance Data. Over 50 ft obstacle. It carries 60 US gallons of fuel in two wing tanks.
Another feature that made the first Comanche popular was the carbureted 540-cubic-inch Lycoming engine that was to evolve to a 2000-hour TBO. 160 Kts cruise speed. The 250s would cruise at around 155 ktas at 75 percent power and burn about 14 gph at optimal altitude.
