I'm thinking about putting a lightweight crank pulley, NOT an underdrive pulley on, but I've read that most don't have a harmonic balancer and could cause premature wear and potentiall failure of my crank bearings but IDK because I've never had one on any of my cars... My other question is is it even worth the $130 for the pulley because idk what kind of power gains I would get.
Our engines do not have harmonic balancers.
You will also not gain any power from a lightweight crank pulley but it does help relieve stress on the engine & causes it to be more willing to turn over & spin, which is not harmful for the internals.
Basically, you will be able to get on/in & off/out of the power much easier & sooner.
For what the lightweight pulley does, I spent $75 on a Kartboy Lightweight Pulley & have been very satisfied.
