No, this was the first time it's been on a rolling road. 
  
As I said, the figures themselves are fairly meaningless to me (290 on a 276 car to start with looks a little optimistic), but it's the difference driving it that matters - and it is a LOT better. I don't subscribe to the "I've got to have 300 bhp" line - it's how the car responds that matters more. 
  
Chris'I, which thread should I post the graphs in?
