I tried a couple of results - one of my very first 21T which completely bog standard 175bhp :-

1/8 ET - 10.377 @ 72.46MPH (15.8 1/4mile) - which came out with 7.12secs 0-60

Then my red 1 from about 1 1/2 years ago running about 250bhp :-

1/8ET - 9.758 @ 78.53MPH (14.752 1/4mile) - which came out at 5.7secs 0-60.

Dont think they are a million miles off!!!!
