Just curious..... have had a single CHT probe on #3 cyl (IO540). Recently added a probe on #1....which runs about 50 degrees hotter (avg 375-395 F) on a rather hot day....OAT about 80 at 4500'. #3 runs 345-350.
I would have thought that #1 would be the cooler, not hotter cyl. Aircraft is a tightly cowled Harmon Rkt. All baffling in good shape and the gauge is an E.I. ....which are pretty accurate gauges. Could P factor be the culprit? ... since both cyls are on the right side.
All comments to this subject appreciated.....thx
