yeh but times can vary too much, temp, track conditions, launch, engine bay temp, traction, air density, gear changes, wot revs u shift at and on and on and on
power is power, from power u can work towards a time, but with a time it doesnt tell u anythin about your power...
all well and good if u only car wot time u run....but i like to know both as im sure most people would
