Alrite, went on the PSOOC rolling road day at Powerstation, Teweksbury today. I was quite happy with the results as it is a standard car, but there is a dip in power high up the rev range, whats the cause of this? The operator said its not much to worry about, as to be honest i dont really rev her that high, but i am just interested to find out why? Is it worth sorting?

That is a little too early though, peak should be at 6600 on a healthy standard engine.

Did you only get the one run? Ideally you need at least two or three to eliminate the possibility of operator error or the wheels slipping on the rollers.

Everything else looks okay though, so I'd say it's most likely the cam timing is slightly out.
