When I raced it was 100% essential to have a car that was bullet fast off the line. To get it perfect every time was virtually impossible but in my car the proceedure was rev to approx 4000 (3900 and it would bog, 4100 and it would light up like a grenade), drop the clutch (no slipping it) and floor the throttle. First gear would take the car to just over 50 mph and the other gears came shortly after. 0 - 60 was probably just under 5 seconds on a perfect start.
Every one was attempting to get a perfect start, any place lost were hard to get back but places gained off the start were far easier than having to overtake later.
The proceedure was very hard on the car, gearboxes would break, drive shafts would break, clutches would break. I was lucky, never had such a failure but I always tried to make sure mechanically the car was as good as the regs would allow.
Such driving has no place on a public highway thus other than for pub bragging rights 0 - 60 times have zero relevance in the real world. The essential permance criteria for choosing my road cars is quick acceleration in the range 30 - 50 and 50 - 70 without having to drop loads of gears. Most turbo diesels have relatively mundane 0 - 60 times but their flexibility is superb, that is why I have been driving turbo diesels since the mid 90's but have now moved onto a turbo petrol which has even better flexibilty and for pub bragging rights a better 0 - 60 time.
Having a revvy engine in a road car that means changing geasr loads is a novelty that soon wears off.
