From their ad:
"Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds.
This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations."
Gee, I wonder if the Nissan engineers are aware of that? Do you think they might have taken that into account when designing the engine? Maybe they didn't realize that burning fuel and air in an enclosed space above a piston would impose torque on the crankshaft the piston is connected to, and that torque would tend to twist the crankshaft.
If you think the Nissan engineers are total blithering idiots, then buy the damper and drive around smugly assuming you've averted mechanical disaster.
My take:

My take:
on a non built motor, no, it is not worth installing
on a built motor, particularly one that likes to rev, yes, these/ATI are excellent pieces to have, as they are balanced much better than a factory crank pulley, and do not have separation issues like factory crank pullies can get over time (where the little elastomer ring begins to delaminate from the rest of the pulley it's glued to)
