For example if your car builds its peak power at 6400 RPM at 270 HP, but when you shift takes you to 4300 RPM with 220 HP. While if you shift at 6700 RPM with 260 HP, it takes you to 4800 RPM wich has 237 HP.

See, your average power output is higher. But this might be diffrent in reality, you know how things go with Paper VS reality.
There is no problem with what you're saying at all. The part you forgot was torque multiplication. The transmission gear ratios and how they affect torque multiplication. A car will not pull as hard in say 2nd gear at 5000rpm as it will in 1st gear.

Just looked at a few dyno runs, seems as though the Cobra drops off hard after 6700rpm. Maybe that is enough to outweigh the 7000rpm shifting.
