Well, maybe B2C2 sets constant power at 9.5 gph per engine?
For normally aspirated that's probably all you CAN get above 10k?
Then, at that power setting, B2CS gets
197 mph at 17k
185 mph at 10k
170 mph at 5k
My turbo Cessna's manual says similar
65%=11.3 gph
194 mph 15k
183 mph at 10k
173 mph at 5k
But then if one uses the turbo...
75% = 12.6 gph (ROP)
216 mph at 20k
203 mph at 15k
194 mph at 10k
184 mph at 5k
