Whoa....You must be making some torque! IIRC Dean lost a hub at Laguna prior to the V8R upgrade.

It would be interesting to see if there are signs of a crack initiation site and crack propigation (fatigue failure). I suspect that a lot of that has been smeared away but it might be there. A close look with a microscope or some photos with a high-res camera using a macro lens would do the trick.

Here are some photos of fatigue failures.

I think I see 'beach marks' or fatigue crack looking marks on image DSC_6768, right in the center, in the lower part of the failure area. Same thing on DSC-6762, lower portion, slightly to the right. Hard to say for sure, both pieces are pretty beat up as one would expect.

Not much to see, but here's a video of a friend in his 911 a few seconds behind me. The v8r people are out until Monday so I have to wait until then to get new hubs.



And another pic. Supposedly, the tire hit the tire wall and was on its way back.

R the coilovers bent or is that an optical ilusion?

Yay for breaking unbreakable parts!

rlogan 09-26-2012 09:02 PM

Yeah, this has happened a couple of times...the guy in Dallas that lost one had about 475hp, not sure on torque.

Cliff's LS3. I believe Saini broke it once and then they fixed it and Cliff blew-up the engine later that day.

I thought V8's were supposed to be reliable?

Here are some pics of the other rear hub that was on the car. It's definitely on its way to destruction. A thin crack is winding around the base at the same point of failure as the other one. The new v8r hubs are noticeably beefier in the problem area and other spots.

How much are the V8R hubs? What's different about them?
Anyone have pictures of one?
