Will higher rpm cause lower cht if the map stays the same? I have a catto prop so I can not test this but it seems like I have lower cht than most. I have a climb prop so it turns about 2750 in cruise.

CHT is sensitive to both airflow and %power

if you keep the MP constant and increase the RPM the %power will increase driving CHTs upwards but airspeed will also increase driving CHTs downward... i am sure that the dynamics between the two are more complicated...

i have a couple of captured snapshots of my skyview with your scenario that show the CHTs stayed pretty neutral with a small increase in %power and airspeed with an increase in RPM while MP was constant...
