Power Flow performance testing
I'm going to have a PowerFlow installed in my '77 J model when it goes in for annual later this month. I want to do some before & after testing to actually measure the benefits I see.
Power Flow claims it will do these things for a J model:
5 -7 knots faster cruise speeds
10% – 15% increase in rate of climb
0.5 – 1.5 gph reduction in fuel burn at equivalent airspeed
Improved Take-Off Performance (100’ – 300’ reduction in ground roll)
Increase in Service Ceiling of 2,000’ – 5,000’

I got my plane back from annual with the PowerFlow installed, and I'm happy with the results. I repeated the performance tests that I did before installation (see my first post in this thread).
Obviously the weather was quite different this past weekend than it was a few weeks ago when I did the before tests. I've tried to equalize that by comparing the actual performance against the POH performance charts. With book performance as the benchmark, the closest I can get to a fair comparison i
