Accelerating from a stand still is an art of engine revs and wheel spin. Accelerate in a professional way is considered as smooth acceleration.
The engine will bog down and the driver will not be providing the tires with atleast an optimum torque they can deliver on the road. But if the engines revs are too high, the driver will exceed the maximum torque, this by spinning the wheels.
The driver will get the maximum possible acceleration, if the driver can balance accurately between Traction and Torque. This is not really possible every time in the real world.
Since the changes in road surface have a greater effect at slow speeds, especially when the car is in first gear and therefore putting maximum torque to the wheels,a driver will have to be complete god to accurately and instantly adjust the clutch and throttle to account for smooth acceleration by keeping the traction vs. torque at the maximum. The only way to achieve this is by revving the engine to high rpm and balance using the clutch. The real problem here is that the clutch will last about ten minutes if the driver keeps that up.
Thus, using a controlled wheel spin is the best method, for this reason. Build the revs up to just into the power band. Smoothly let out the clutch so that the wheels gradually start to spin and balance the spin to be just before they are starting to bite again. Keep this up until the car is at a high enough speed that the wheels could grip and would still be in the power band.
