DIY: Nonstop Tuning CR-Lite Pulley

[cfbrodierice]

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....

I'm an automotive engineer abd what he is saying is true, going to these aftermarket pulleys is turning your 400k+ potential Yaris into a throwaway car, might as well buy a kia.
