I see that the air speeds of the Turbo III is at 175kts. I am guessing this is @ high teen altitudes. Also, is that seen by many pilots for real? Does the turbo have any advantages in speed at say FL40 to 100
I realize the turbo is for getting over those pesky mountains but I live in flat lands and am looking truly for long distance speed not high FL.
What do people really see at 65% and 75% power @ FL70 lets say.
Thanks,

I fly an Turbo Arrow IV. Also live in the midwest flatlands. I love the turbo. No turbo-related maintenance issues in 3 years. A little more gas. No power loss all the way up to the teens. Climbs 700-1000 all the way up. No issues on hot days. Speed 160 true at 10K. 150 True at 6K. Go for it. SJ.
I usually fly a turbo equipped plane, but recently rented a non-turbo (182) for a cross-country flight.
The bottom line is this: When you cannot hold the MP you have dialed in, you are losing power, and speed.
For our conditions (relatively warm ambient temp), I noticed that for the 182, the MP (set at about 75% power) started to drop around 5000 ft.
At 65% power I suppose you could have flown a bit higher before not being able to hold the power.
For hot summer days, more power loss for a given altitude.
4,000 ft: Small difference
10,000 ft: Huge difference
A nice bonus with the turbo is the mixture setting is not as sensitive to altitude change. Whether I take off from sea level, or 8000 ft, just full rich.
