DIY: Nonstop Tuning CR-Lite Pulley - Toyota Yaris Forums

Hello all, I am brand new to the forum. I work on landcruisers and such. I am thinking of buying a yaris for a commuter. Just one thing to say about a lightweight crank pulley... and just my .02....
There is a reason it has a certain weight, so that any vibration in the crank is partially absorbed through the harmonic balancer. you change over to a lightweight and solid pulley and it no longer can do it's job. Ya your engine accels faster, but long term it could make your main bearings wear out faster....
