On inertia dyno runs, does the run show improved acceleration or a decrease?
On dynos the time that it takes to go from clutch lock (3500 to 3800 rpm) to desired rpm is much quicker. Managing the chain’s mass and using the force that it generates, (the chain is already in motion getting to clutch lock) it is like an additional weight (Fly wheel effect) and it allows the engine to reach high rpm’s at a more rapid rate! Also when on the dyno, the difference net horsepower and torque graphs are much more precise as the vibration (chain harmonics) is dramatically reduced or eliminated. This same set of circumstances is addressed when on a kart, racing or testing. As you know every dyno is different and the engine builder who is doing the work knows all of the base lines he needs. I have seen how precise the numbers are when a dyno that has a belt maps out. It is impressive with the ChainDragGONE on because the pulls are much smoother and more accurate.
