Thanks for posting that. I figured I couldn't be the first, with all these people tracking their cars.

Obviously that engine was under a lot more stress, so you could expect more risk of failure in general. However, intuitively I would not expect the oil pump gear to be under significantly more stress in a boosted application unless he was revving really high. Even then, I wouldn't expect it to come apart like that.
