CHT Temp Difference

by Phil Hale in 912 / 914 Technical Questions 13 years ago

What is an acceptable difference for the CHT's as I am getting the 190F on number 2 Cylinder and 230F on number 3, at cruise? When I climb out the number 2 gets to 210, number 3 temp gets to 260F. I am concerned about number 3 temps. The Carbs have been synced at 3000 rpm and all coolant hoses have been checked and are OK. Thoughts please.

Hi Phil,

It would be nice to know what the EGT's are for the same cylinders? If you have the info CHT's and EGT's for # 1 & 4? You are right that 40F is a pretty wide spread. I'm any where from 0-10F difference and 15F would be acceptable.

Hi Roger
Thanks for the reply, I have not yet fitted egt to the aircraft. I will need to buy suitable equipment as I do not have compatible equipment. I will repost when I get egt's fitted
