Did he back off at 331? Was there more to give.....? it didn't seem as if it was slowing down much. Absolutely incredible achievement. I wonder of it comes with a 3 year warranty, roadside assistance and a service pack for £1200.
Impressive stability at those speeds - the fact he was comfortable to drive it one handed while slowing down through 200mph at the end of the run impressed almost as much as the top speed.
