Depends what cam you have fitted and the ratio of the rockers.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

Mitsi Evo 7, 911, Cossie. & all the chavs ...... won no problem

if its a standard turbo cam i would ditch it for a more performance cam
lets say a N/A MG cam or the blistering avonbar phase 2 or a kent 266 maybe?

0.014" would be my setting on the standard turbo cam
