My cruise settings

Post by awash2002 »

Here is my own personal power settings for the Bonanza with the IO-520BA

2500rpm 14.0gph target EGT 1403f Target CHT 190°c

2400rpm 13.0gph target EGT 1404f target CHT182°c

2300rpm 13.0gph target EGT 1380 target CHT 180°c

Me personally I use the 2400rpm power setting try these settings and feel free to modify them

For the IO-550 add 1gph to the above findings

True Air Speeds
2500 171
2400 167
2300 163

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.
