Dingy, you should be mid 8s in your car i would have thought.

Two friends i was with last time were both running the 8:40s, one in a not very modified golf fwd 1.8T and the other in a totally standard M3

Getting under 10 mins is a doddle in more or less any car, a guy on the vauxhall forum i use did 9:14 in a 1400cc nova, with probably not much over 100bhp.
