Had a couple of dashes to 60 at the weekend.
First time from a layby, bit dusty so the wheels slipped a bit in first. 6.55 secs.
Second time, no cars about so I stopped on the carrigeway, got the perfect start, no wheelspin, good traction all the way through first, quick smooth gear change to second.....6 secs dead !
Not done with specialist equipment but still a good measure I think. Used a digital stopwatch. as soon as the car moved I started it so it was from a standstill.
Only mod is a Green Filter.
