George,
Can you please explain the math there?
How do you get more HP at 5,000 with the same MP as sea level?
Is that because there is less pressure at the exhaust?

Posted for "George Braly" <gwbraly@gami.com>:
Why would you lean a TSIO-550 engine at a field with 5 or 10K density
altitude?
The turbo at redline MP and RPM makes more HP at 5000 feet and 10,000
feet
than it does at sea level.
Not a good time to lean it.
There is an NTSB report on this subject. A crash at Pagosa Springs from
some
years ago. P210 leaned on takeoff. Not a pretty picture.
Regards, George

Walter:
Any thoughts about leaning the TSIO 550 engine for high altitude
take-offs. (5000' +)
Thanks, Bill Hogarty
