Nice one Phil, fantastic, it's few years since I last watched that.
I can relate to the engine noise alright, - but not the gearing. It looks like any hint of a corner and he's into second gear, even taking Tertre Rouge and Arnage in first! My old box would be sitting next to me in the passenger seat if I tried shifting it into first at anything above 10 mph. - in fact, the original owners manual states, rather optimistically in my opinion, that first should only be used for hill starts. I got on the track one year, and was surprised just how slack the curves really were, I could easily have stayed in fourth gear from the Ford Chicane to Tetre Rouge.
Great clip.
