So for everyone who's blown their motors, I've always seen them run higher than OEM redline. I've seen the VVEL blow, the bearings blow, and the oil pump blow. I know the high rpm's killed those motors but I'm wondering how many had lightweight crank pulleys installed also. It just seems too risky.

And from holding a bunch of OEM crank pulleys after installing lightweight crank pulleys, they all seem solid but they're not. They all have a tiny rubber section splitting the two halves that you can move back-and-forth even with your own hands. Now imagine what kind of movement back-and-forth that can have at an 8000 RPM shift point.
