The weight, altitude and passenger is not unusual. Should have gotten off
better.

Tire pressure, winds down the runway and lift off speed are among many factors. Try this when your by yourself. Pull the nose off gently at 55 kts (it reduces ground friction a little less than a third)

I tried this and it works but I have to admit that normally I pull back at about 60 to 70 kts.

interestering. I realize that there was a good cross when I had my "raised awareness" take-off. So I was on my left brake some on initiation.... I am sure that that added to the condition.

Has anyone noticed major differences after an 0-320 conversion?

OK guys

I just got a confirmation from my earlier posts to Dave.

Last night it was 91 degrees, west wind at 15. I took of at 7:30 pm.

I took it up to 3000 msl, trimed out and ran the throttle full foward.

I was pushing 143 kts indicated at 2750 rpm. I took off the CHT probes a few years back so I can't tell what the CHT was. Oil pressure was pegged at over 90 psi and oil temp waas running about 210 degrees. When I stopped pushing it, and dropped down to 120 Kts the Oil temp dropped down to 200.

The engine still has less than 10 hours on it.

This has been a long running post but I would be interested in comparison data or break in tips.

90 psi oil pressure sounds way to high to me.  Have you made any adjustments to it?  I would expect 50 - 60????

RPM at max throttle sounds a little low, but this is more a personnel preference. I used to run at 2900rpm.

The oil temp sounds like it may be dialed in, just a tiny high but acceptable.

Start & Warm-up          100
Start & Warm-up N2C   115

Oil temp

Above 60F                  Desired                    Max
                                    180F                       245F

Just found this site on another forum.

It just about confirms our earlier findings
