I posted in another thread about my prop experimenting. I have an O-320 with a Catto prop. I am getting around 197 MPH TAS or so at 2800 RPM at 8K DA. I can go LOP and it drops to 2700 / 190 MPH.
While I am happy with the 2700 RPM setting and speed, I am wondering if I can wind it up to 2800 if I am in a hurry. It only burned another .7 GPH or so and could see myself making that trade-off. I have seen some people saying that the O-320 has no problem turning that RPM on a continuous basis. 2800 at that altitude was indicating about 80% power.
I am hoping to hear from those with experience in this area. Can the O-320 handle 2800 or is that creating a potential for problems. The prop is rated at either 3000 or 3300. I can't recall which was on the placard.
