Nice video. I couldn't help but recall the advertising of the day, and don't know if it was for MG or for Austin Healy or both. It went like this: Basically a stock production car with nose and tail sections replaced (I can't remember the explanation for this), the engine was "tuned" (in British parlance, this meant that everything possible had been done to the engine internals), and the supercharger was to compensate for the higher altitude (yeah, right). A bit of British understatement.
