A Bonanza? Yes. I bought one. My S35, which is the fastest model, cost
me $88K this past August. At 75% I indicate 165 Kts and usually true at
172-175 kts. That costs 15 gph. 165 kts true costs 13 gph. 155 kts true
costs 11 gph. Want to bust your buddy's in the 182's chops? 19" and 2100
gets me 135 kts IAS on 9 gph.

How are you leaning?

I would concur with Newps' numbers. At 75 degrees lean of peak, wide open
throttle, and 2500 rpms, my V35B with a turbo-normalized IO-520 will true
between 175 and 190kts (altitude depending) and between 15.5 and 16.5 gph
(OA temperature depending).

19" and 2200 rpms will also result in similar numbers as his, again keeping
mixture LOP.
