My RV-4 has a 160 hp Lycoming (IO-320-B1A) with a MT-Propeller (Constant Speed MTV-12-C Three Blade). My RPM on takeoff with full throttle and full forward Prop (min pitch) is consistently around 2770 RPM. The Lycoming manual specifies a normal rated RPM of 2700. Assuming my EPI 800 tachometer is accurate, should I be concerned?
