For the upside down view dunno maybe a cellular cam record maybe. It doesnt matter how it is record.

For the accelereation issues dunno but car is going well till 220kmh to me but after that it is not as good as like the acceleration like 220kmh.

With this video i cant stop thinking like Kreso as the old topics about porsche 997 Turbo accelration to the 200-300kmh

BTW is the overboost issues ok for the video. Normal?
