Vmax is a great event, no winners just car against the clock or a grudge match with a mate.

To give you some idea of performance/power.

400bhp- 168/170mph
450bhp- 175/177mph
500bhp- 180/182mph

But it wont lie lads if you aint got the Power you claim your porkies will be exposed.

Even a 400bhp Cosworth will be OK & run with say a 360 Ferrari they are crap at this struggling to reach 170mph.
