Re: My cruise settings
I researched the ABS (American Bonanza Society) forums relating to CHT and EGT per your posts. Accordingly, there doesn't appear to be firm guidance as to max EGT, however, most favor EGT cruise of about 1360-1400F.
I usually operate my A2A V35 IO520 @ 22 in / 2300 RPM / 12-13 GPH; typical cruise CHT is 175C (cowls closed), EGT ~1380.
All the best.
