You need to go to a rolling road.They strap your car to two rollers in the floor then they hook up some diagnostic equipment then one of the workers will get in the car and floor it.This shows power, torque and top speed.

A rolling road will only show Brake Horsepower and torque, it cannot show top speed as it does not measure coefficient of drag or rolling resistance for the undriven wheels.

Sorry I cannot help you arshad.

You need a rolling road and a wind tunnel. If you know the drag coefficient, the peak power and the frontal area you can calculate the theoretical top speed. Otherwise, find a bloody long road.
