One of the functions of the dyno is to read horsepower; it does this by measuring how fast the dyno drum accelerates, then calculates horsepower, taking into account the atmospheric conditions. To get good data, this should be done as close to a 1 to 1 ratio as possible. (Example: a motorcycle with a 6-speed transmission, with 6 th being overdrive, we would use 5 th gear for dyno runs.)
