When it was first developed in the early 70's there was a method for selecting carb jets etc. The driving wheels would be removed, the car secured on stands, the accelerator floored and the brakes applied to pull the revs down to 2k, 3k 4k etc for a colour reading. Usually it was necessary to let the brakes cool between readings.
