CHT: which cylinders?


Recommended Posts

Usually the front 2 cylinders are the hottest---however, for those who have paid good attention to balancing the heat, you can end up with them being the same (ideal) or even overbalanced in the other direction (hotter in back).


The real answer is that nobody can tell you---you need to find out yourself. Personally, I would never own an airplane without all 4 CHTs and EGTs monitored. This is from a monetary perspective----you've got somewhere between a $10K to $20K engine----a $2K engine monitor is a cheap investment to make sure you are not abusing the engine. And also, this is from a safety perspective. You will be able to pick up warning signs on your engine via an engine moniter before your ears and butt will ever pick it up.
