Underdrive Pulley - Toyota Yaris Forums

ruimond · 01-12-2009, 01:24 AM

Just purchased the underdrive pulley from NST as well as cable bushings over the weekend. I have been reading around about pulleys and obviously they provide alot of benefits.

Just have a question that i've read about, Stock crank pulley are suppose to have dampeners on them to absorb the shock and so forth. How much they absorb i'm not sure. Im not sure if the Yaris crank pulley even has these dampeners to begin with. Anyway i realised that the NST one does not come with dampening as it would cost more.

No one has complained about any issues running these pulleys, but i was just wondering can un-dampened pulleys cause any damage? What are some peoples thoughts on this question.

Im still gonna be installing it anyway, but yeh any input would be great on this issue.

Cheers
