Anybody aware of any data indicating actual air temp at entry to the cylinders?
Outside air temp surely is increased due to ram rise?, exhaust / hot oil heating of the intake plenum?
My engine is a stock IO-360-A1A. Not sure if fuel injection into the cylinder head cools the air significantly.
Thinking I may install a temp probe in one of the intake tubes to know for sure. Won’t have a “before/after” as I have already wrapped the intake tubes, and exhaust is presently off for ceramic coating.
Thanks for any thoughts!

Jeff
