Lightweight Crank Pulley?

nah man, i say that all the time.

Fluidampr brand, or another SFI approved weighted damper, or the stock balancer. nothing else.

lightweight crank pullies are bad news.

i remember a test that was done with a VW 1.8t, stock vs lightweight vs Fluidampr brand SFI damper.

lost power with the lightweight, and gained a bit over 5WHP with the fluidampr, as well as reducing vibration from the engine.
