My question is...How long does Sterling dyno the engines? I understand engine pulls on the dyno for max horsepower and torque but, do they run the engine at 1/2 or 3/4 throttle for an hour? 2 hours? 12 hours? to see the real time longevity of this expensive engine that they are about to release to the public? They should have a dyno that is set up to do that.
