Hi Adam, good seeing you, worth the early start, very impressive and sounded sweet.
At least you sorted the problem out and its most likely cheaper than getting a garage to sort it.
Talk to Mick tomorrow, as he reckons that he can arrange a RR if enough of us are interested.

The graph showed there was something not right as there is a dip after the power valve that never recovered. Some rolling roads do suffer inaccuracies but alot depends on the quality of them and how well they are maintained and managed. Catch up tomorrow fellas.

i beleive this one to be about right. its fairly new and well looked after. 183.3 bhp was most proberly a very accurate calculation if my power valve was playing up. the main thing is it made good torque at 190ft-lbs

It was the torque curve that I was looking at. The dip without recovery from around 4,500 rpm that was the giveaway. The torque curve for the KV6 engine should be fairly flat between 3,000 rpm and 6,000 rpm.
