Who's running a lightweight crank pulley?

shoeless89

Thanks for all the input everyone! I think I'm going to stay away from a light weight pulley, for now at least. My Z isn't my DD but it's not a track car either. I do drive it quite a bit and don't want to sacrifice reliability/longevity of the car.

I've got a brand new NST pulley (black) just sitting on the shelf my garage. I changed my mind about installing it after reading the above and other opinions about the negatives.

It wouldnt really make too much difference, it only makes a difference in two occations that i know of, longentivity of the crank front bearings, and the damping stress of high engine rotations.

Basically the rear of the engine is where the transmision and load of the car at, on the front you have the load of engine parasites ie. Pumps, valves, alternator, the balanser is a heavy metal that will balance the rear and front loads so that the bearing wearnout on both sides of the engine the same speed, also keeping the vibrations low as well.

Removing or ultering these two will result in long term engine bearings rapid wearout if you dont mind then yeah throw light weight pulleys on and go racing, just remember to be ready to swap bearings sooner.
