lightweight crank pulley- WORTH IT?

cooperlee · 04-21-2010, 06:39 PM

Thinking of picking this up......has anyone installed this and felt it was a good mod?

wondering the same.

waste of money imo

don't change your dampened OEM pulley for a non-dampened one...i bought the NST pulley and sold it a few days later as too many people in the know told me to not do it, both on this forum and outside at really good performance shops that build race cars for a living

Thats right youll induce harmonic vibrations losing the rubber damper thats pressed into the pulley. Not healthy for rod/main bearings...its there for a reason.

Has anyone else tried this mod, so far? I guess that having so much torque the lightened pulley wouldn't have such an important effect (different to N/A cars).
