306 kph run in my standard C6 Corvette. Late for work! The faster it accelerated, the more it sat on the road which allowed me to film with one hand and drive with the other. Started to really feel the wind resistance at about 280 kph. Further down it did 311 kph but I had to slow down due to speed camera. I took a photo at 311 kph but was grossly out of focus.
