Hign CHT temps on rear cylinders during climb

Postby sx1094 » Wed Jan 03, 2018 6:14 pm

Been having high CHT temps on the rear two cylinders during climb. I understand there is a mod that can be done to eliminate this problem. Can somebody please share it with me. Thanks for the help.

I think first you need to determine whether it is because they are running lean or because they have insufficient cooling. What are the EGTs like and what happens to them if you lean a little?

EGT temps are fine. If you lean at cruise the CHTs rise also.

Assuming you're talking about a VW conversion ... this is a topic of much discussion on this forum. Here's one recent example:
