If you know engine HP at any given time, you can calculate acceleration as long as you also have weight.
If you know engine TQ, well, you cannot calculate jack without knowing a lot of additional information beyond weight.
Or put another way, knowing just a cars power to weight is an execellent approximation of acceleration. TQ/weight won't tell you a thing unless you also start talking about gearing and RPM at which point you know HP and could have just used it to start.
But by all means continue to worship at the alter of engine TQ.
