Sorry man, you are infact breaking the rules. I know you aren't really breaking the speed limit, however, you are trying to film the speedo/tach and drive... that generally isn't allowed.
Rule #14: Posting pictures or videos of any tach/speedometer at highly illegal speeds is not allowed. That is way too dangerous and just encourages similar behavior. It does not matter if it was taken at a track or any other place where such speeds are "safe", there is no way to tell that it was not taken elsewhere. Similarly, posting about your high-speed escapades on public roads is forbidden.
The car does sound good though.
