our damper face is OEM location for the pulley mounting surface and we also have a damper with the chrysler 6 bolt on the 2.81 bolt circle so you wont have the blower pulley stick out.
a damper is an inertia weight that is surounded by rubber o-rings. when the crank acts on the damper the inertia weight (riding on the o-ringd) will counter the cranks action. a belt cant do this since it doesnt have any mass to counter the action.
if the belt was the answer then no motor would need a damper since ALL motors have one or more belts on them right? what makes the blower belt different than a power sterring belt? if the blower belt worked on harmonics then the aluminum pullies wouldnt have chatter wear in the teeth.
on our website we go into this in detail but i'm just trying to understand the logic.
i understand that in the 50s when a stock damper would crack you needed something else and that most blower motors never made it more that a couple of passes till they pulled another one from a junk yard, but this isnt the 50s any more
think of it this way. a drum kit has a symbol and when you hit it it will ring now if you hold the symbol it will just thud, this iss like a damper the o-rings are your fingers and the symbol is the inertia weight and the stick is the combustion. if you hang rubber from the symbol and hit it it will still ring, this is like having the belt only.
