Default OS 160 FX

I currently put an OS 160 FX in a CMP PT-40 Warhawk with a 16x10 Master Airscrew wood prop. Instructions say 1,800-10,000 operating range. I am currently getting 9,400 rpm and thought that was perfect. I realize in the air it will be much higher. Should I go to an 18x10 and does anyone know how many rpm it will drop.
