the only place an 8v would be quicker is 0-30ish from standing
myth. the only time an 8v will beat a 16v to 30 is when the driver of the 16v can't get their power down for whatever reason (greasy road, crap tyres, riding the clutch).
you'll be close, 4-6 feet in it, until the 8v driver has to make his first gear change at 6k, the 16v pulls all the way to 7k, and that point the 8v has a nice view of the rear of a rapidly disappearing 16v.
