does the oem pulley have a rubber ring in it? a dampner?
if it is, then the NST doesnt have a dampner. every time the pulley hits TDC or BDC you're slamming the pulleys on all devices and as the pulley rotates towards bdc or tdc the pulleys are slowing down. that's what the dampner does....dampen the force of the engine 'bang' to equalize throughout the rotation. |
