    I believe the 6 in DM6 indicates 6/16ths (3/8”) prop bolts as opposed to DM7-7/16” prop bolts.

When I read/researched, it sounded like a 58" for the 160hp, and 56" for the 150hp were ideal, so I went with 56...never tried the 58 though so don't have much comparison, just glad I can still cruise at book numbers without a problem, and I certainly have a shorter ground roll than book numbers.
    I fly a 150HP TP too with the 56" prop. My cruise is around 100-105 (at 2400 RPM) burning 10GPH. Looks very different to yours

    Default Climb Prop

    The original prop that was on my ‘57 PA-22-160 was a -60. It was great for cruise, and ok for “normal” airports. I used the airplane banner towing, and the first couple weekends had the -60 prop on it. Worked ok, but was pretty much limited to less than 35 5’ letters. I had the prop re-pitched to a -53 (the full 7” allowed). With the -53 climb was great! Off the ground in about 200’, climb between 800-1100 rpm depending on weight. At 1000’ well before the end of the 5000’ runway where I was based. Main problem was over 80mph with full throttle you would be past red line on the tach. Cruise was down somewhere in the 110-115 range. But boy could it pull. One day by mistake (I thought it was a shorter sign) I pulled 62 5’ letters. I also ran a second oil cooler attached to the nose strut to keep oil temps within limits.

    Fascinating. All good compressions on the engine? I've got a newer engine (only 150hrs SMOH), extended Stewarts tips too - perhaps that's contributing?

    Something seems wrong with the numbers your getting...

    I'd check your Tachometer and your Airspeed Indicator

    Burning way too much fuel at 2400 rpm. I would be down around 7.8 or less, leaned.

    I’m running an 82-43 on my 150 and getting 2490-2500 on take off, and red line in cruise. No idea if that’s good or not since this is my first O-320.

    I just installing a fuel flow computer. So in a few days/weeks I´ll have exact numbers. And I´ll compare it with the GPS. I've never done it exactly.
