I lowered by radiator by 1 inch with much improvement. The aluminum radiator helps as well.

Doesnt hurt to verify RPM with something like a Tiny Tach. My analog one was off about 300 RPM. I was running 6100 static and 6500 on climb out with a 3 blade 68" Ivo. Getting the pitch right had a big effect on cruise speed.

Hi!

I set the mixture to 70% water and 30% antifreeze - I have protect water up to -20 Celsius by this mixture.

582 greyhead with GSC 68"
At hot temperature 6300 rpm during climb with 1000 ft/min.
At cold weather 6000 rpm.

NOTICE: more prop pitch higher altitude, more airtemp - less EGT!!!

IDLE JET: 1/2 turn left less EGT (richer) than 2 turns left !!!

Regards!

You may want to check the water pump impeller sometimes they get to much wear and will not push /pull coolant just something to review ?
