I have not built a drag race car and it is difficult to do a perfect start from 0-60 with normal street tyres on the road, especially with a manual gearbox and without any launch control or other helping system on a big Audi S8 with over 800Nm
And I also don’t want to break my gearbox only to get a low 0-60 time on my car.
And with manual gearbox and street tyres, if you get a low time I would say that the credit for that is maybe 40% the engine power, 30% the grip of the tires and 30% is the driver that launch at right rpm and change gear at right time.
So there are several factors that affect the time and not just the engine power.
But if you are running on one gear 60-95 mph then it is 100% engine power which gives a good time.
But for 60-125 mph then I have to change one gear from 3rd to 4th so then it's maybe 25% of the time how quickly you can switch and the rest is pure engine power.
So best test between cars is 60-95 or 60-125 mph
Or in my case 100-150km/h or 100-200km/h
My car last year did 100-200km/h on 7 seconds
Here I found a comparion chart for 100-200 km/h times on fast stock cars but that are slower than my car
