Hi all,

I am looking for real operating temperatures people are getting with their 912ULS ' s .

I know there are lots of variables, but I am interested in what you all are getting for running temps.

On my KF5 smooth cowl , Outside air 40 F at 5000 rpm , 25.5 manifold INHG prop in cruise

with approx 2/3 of oil cooler taped over= oil 206 F ,

CHT's #2 = 190F ,#3= 195F .

EGT's # 1= 1341F #2= 1364F #3= 1312F #4= 1369F

coolant 171 F ( measured just before going into rad) also was running cockpit heater

I am still having rough running in the 2500-3000 rpm range after multiple carb syncs and all carb rubber parts being replaced(O-rings, diaphragms,sockets) . I am thinking of dropping my carb needles to position # 2 to lean out the mixture in the mid range. needles are currently in the #3 position. The engine performs well in all other areas except the 2500-3000 rpm range.

I would like to know what others are getting for running temps to help decide what to try next.

On my Outback (smooth cowl 912S) I am getting 180 oil and 160 coolant with no tape over either radiator/cooler with an OAT of 45 degrees F. When OAT's are nearer 75F, they are 200 and 170 respectively.

I plan to tape up 1/4 of my oil cooler soon as winter properly sets in to maintain 200 (oil) if possible. I'm not fussed where the coolant temps are as long as they are between 150 and 190 that's fine with me.

Hi Monocock,

I have read the other post, not much info on EGT's , I would like to put all the numbers together in one place
