The factory oil slinger is prone to failure regardless of how fast the blower is spinning. Not to say that couldn't have contributed to your issue.

Aaron is correct about the oil aerating and not lubricating properly. That was verified with vortech. Fortunately, mine never had that issue, maybe due to the ceramic bearings I had installed.

My 928 impeller had a vane break off and the sc ate it. I haven't opened it up yet to find what damage it did, but it's noisy as hell too. I'm hoping it's rebuildable. Carl at 928 was sent pictures of the impeller and he never accepted responsibilty, he just told me not to run it anymore (no sh1t Carl). I'll never do business with 928 again.

It sounds to me like your bearings are bad, I've seen where oil slingers have failed and metal particals have gotten into the bearings.

If you want to overspin the sc like I was doing also, go to the V2 H/D Ti like Aaron recommended to me. It has heavy duty bearings and although it's rated 52000rpm, vortech verified it can be spun at 60000 with no issues. It's also external oil fed so you won't have the aeration issues that the V3 has.

Edit: The V3 oil slinger isn't prone to failure as I stated above. They have been known to fail.
