Just curious, what issues did you have with these lightweight crank pulleys?

Shortly after upgrading our ECU, allowing us to rev past 6500rpm, they started failing.

The NST one split in two around 7000rpm. The BeatRush unit had some weird harmonics and beat up the crank pin. Just was not willing to risk a third.

This was about six months old, less than 1000 miles, I think the second time was ran the car with the higher rev limiter.
