| :I disagree. Harmonic Dampeners minimize torsional vibrations that are the result of normal combustion events...whether or not the rotating assembly is internally balanced or not doesn't matter. Removing the harmonic dampener will increase the amplitude of these torsional vibrations...the question is whether or not this will cause damage. First keep in mind that the stock crank pully only has a little rubber dampener(not a balancer) because the motor is perfectly balanced. Torsional vibration is a twisting vibration caused by the pulses of each combustion event. The force of the piston causes the crank to deflect ever so slightly in the direction of the force, and when that force goes away the crank ever-so-slightly springs back. At certain frequencies the crank can resonate, making the vibration much worse. These vibrations are more evident in motors with longer cranks. V6 only has a crank length of 3 cylinders so yes the vibrations may still exist, but you can imagine the length of the crank(or lack thereof) helps keeping those vibrations at bay. The motor is built well and we have never seen a case where bearings and/or crank was damaged....scratch that, actually I've heard of one with stock pully.
