What is your static RPM? Typical is 2200-2300, depending on pitch for cruise or climb and prop/engine setup. My 3 blade Catto, for example, is around 2200 RPM static. On take-off, I look for 2250 while rolling down the runway. I can just get to 2700 RPM at WOT. I did a run yesterday after tweaking the configuration of my P-Mag with my computer and EICAD program. At 5700 feet, WOT and 2700 RPM I achieved 168 KTAS.
I need more HP and aerodynamic cleanup but happy with the prop. Also, gear fairings and wheel pants make a huge difference in top speed.
