Is there actually any adverse issues that come with going with a light weight crank pulley? I found a thread a few days ago but forgot to copy the URL and post it in here to get the experts input, but long story short they were saying that the LWCP can lead to severe issues like knock or throwing timing. The one thing most people who sounded smart about the issue said that with it not having a harmonic balancer associated with it it tends to cause vibrations that just get worse and ultimately end up destroying the engine.
