Not that this tips things one way or the other, but the Mooney 201
I've flow (a '77 model) wouldn't do 170 knots. It was a 160 knot
airplane.

To get 180 knots, the SR22 burns 18 gph. I think the actual number
was 18.8 gallons per hour, but I'm going from memory here.

I was quoting book numbers for both; I'd assume that each would take a
similar real-world hit if not spiffy clean and perfectly rigged, with
a skilled test pilot at the controls.

That said, for the plane you flew, did you check the tach? A small
calibration error could easily account for a speed loss.


All the best,
