Find a private road which is long and has a consistent gradient, does not need to be flat, just consistent.

Choose a start speed and end speed of your acceleration run

Record the time it takes the car to accelerate between these speeds

With car out of gear, record the time the car takes to decelerate between these speeds. This time will compensate for wind resistance, wind direction and speed, rolling resistance of tyres and the gradient of the road
