283 km/h with senator

Hello guys I just broke through the sound barrier !!! I recently brought my C30SE a little to the front, now he has according to Bosch performance test stand 254 horses. Since I was a little curious I drove on the track last night and just made gas. The tacho stopped at 283 km/h (there is still something more horny than speed ??). What kind of feeling I have left everything there just WOW !!!!
