A dyno (dynamometer) is a machine used for measuring force, moment of force (torque), or power, plus other engine vitals. A vehicle is driven onto the dyno via ramps & strapped down. It is then driven on the dyno, allowing us to replicate road driving conditions at different speeds, RPMs, elevations & loads. The dyno’s computer will then record all the vitals, such as power & torque, plus other important engine readings like air & fuel mixtures & turbo boost pressure, as the vehicle is run on the dyno. It is a very important piece of the puzzle when it comes to tuning a vehicle properly.
