Turbos altitude advantage

Fixed it thanks for your feedback.

Hmm...+70C is about +158F...and here I thought Texas was hot!

I have a 1969 T337D with a Robertson kit and I have to say I totally agree with N86121. The airplane is just amazing. Climbs without hesitation up to 19000 ft, which is the highest I've taken it so far to get over the Rockies. Lifts 850 lbs with full fuel. And the engine out service ceiling is 19k ft on the rear engine, 16k ft on the front. So I can lose an engine over the Sierras and basically coast into Livermore where I am based. Every once in a while I look around for other airplanes and keep coming back to the T skymaster. In the west I would not want a non turbo airplane. A P model might be nice though....

Some great info here. Though I am largely a flatlander (here in the northeast our tallest hurdle is 6288ft, and a standout at that), as my opener mentioned I have put some stock in the discussions various and wide about climbing above IMC conditions. I'm not especially stoked about the extra cost of maintenance, but our weather here is (in)famously unpredictable. Guess I'm pretty much sold on the idea of a turbo at this point. I'd still love to hear any anecdotes from those who've found themselves with a sudden need to climb above weather.

I'm not quite sure of what you're aiming for in using the Skymaster.
What will be it's mission 80 to 90 percent of the time. Will it be mission critical (delivering human organs!) or personal (you can pick your weather).
I have been a corporate pilot for over 25 years and been blessed to have flown a variety of aircraft including jets. I've flown normally aspirated Skymasters and currently own a P337H. I fly it from northern Ohio to central Florida non-stop in the high teens at 62% to 65% power and it gives me 180kts with plenty of reserve fuel. I can say that the previous comment about the extra power to climb above icing is good, especially if there is high terrain below, but it is only good if your flight is going to take you beyond those conditions or you will just be decending back through it.
Cruising above 10000ft will definitely put you in smoother air above the thermals of a hot summers day and a normally aspirated Skymaster will easily do that, although not quite as quickly as a turbo. Other types of convective activity comes in many shapes and sizes and many cannot be topped by any type of Skymaster!
In respect to the TSIO-360's longevity, I agree that ANY engine will reach TBO more easily in the hands of a smooth pilot and not a throttle jocky, especially the turbo'd versions. Also it is critical for a turbo'd engine to be set-up or tuned correctly to live long and be happy. Items such as unmetered fuel pressure, metered fuel pressure, turbo wastegate settings, and spark advance need to be adjusted correctly in relation to each other, and require a mechanic with the experience and the tools for the job.
But getting to the point. It sounds to me like you are looking to buy your first Skymaster? If that is the case and most of your flights are not long or "mission critical" I think you would be happy with a nicely equipped normally aspirated version. Save a little on maintenance costs now and get to know the breed. Trade up later if you feel the need.

Thanks Tom.

Yes, I'm looking into my first Skymaster, but the mission isn't entirely known in advance I suppose. What I do know is that it will be recreational only, as in flying to recreational destinations. I imagine the vast majority of trips will be single-hop, 2-4 hour trips. Maybe once a year I'll go beyond that, but more likely a tri-ennial kind of event. One concern is where I often see people get into trouble: they've planned a vacation and when it's time to come home the weather isn't so great.

Point well taken on the convective activity, but being able to quickly climb out of icing conditions or up into fast-cruising territory is appealing. On the other hand, I have an unnatural (yet justified) fear of finding good, competent help--thanks for tapping into that.

More valued feedback, thanks Tom.
