Vref, that is what I see. I run at 9k, 11.2 fuel, and see about 160. That at 65%
Not bad numbers…you have the IO470N right?
Coming back to the question , the Bo six cylinders performs better then an IO360’s My previous 200 HP M20J became asthmatic at FL100. The Bo is a better performer for European ENR IFR IMHO as you need to fly most of the time >FL080 anyway to have some route efficiency….
Anyway being 155 160 does not matter too much as the wind is the major factor my trips are min 3hr30 till 4hr15 depending tail or headwind..
Got a DCT two weeks ago from DKB (Dinkelbuhl VOR) till STO (Vienna) that’s 242Nm…for those who don’t believe it I have a picture of it.. 
400 to 450€/h by 120-150h a Year
A good value book is John Eckalbar’s Flying the Beech Bonanza, also useful because it makes you think about other types and how the author might analyse their characteristics. In short a good primer on aircraft performance.
Yepp I have that one excellent wrting and quite scientific approach
Honestly I don’t calculate its bad for my emotional state I have done some expensive upgrades new interior, 8.33 Khz,EHSI, tip tanks and a partial repaint
But fuel wise btw the Bo and Mo is not that kind of huge difference as people often say. E.g I burn about 25 liters more with the Bo for a 580 Nm stretch however much more faster, comfortable (noise, vibration and seat comfort)

Oh yes, I can relate to that . Nevertheless, would be interested in some numbers.

What’s included in that number? Obviously more than just the maintenance?!
I can’t as my Mo was EASA reg and the Bo N reg it’s like comparing apples and oranges IMHO
Yes, highly recommend Eckalbars book. In terms of internals, the major difference in the Bonanza, against most other types in class, is the space, comfort, and stability. Flies like a mini airliner….
Blueline, for an average 85-100 hours per annum, I budget £28,000.00. That’s everything. That figure includes some of my planned maintenance items. These are not cheap aeroplanes and like all frames, require regular and knowledgeable maitenance. Now that could be another discussion altogether.
