I would like to challenge any of you who have done over 10 track events to tear down your motors and show us your rod bearings. Talking to those who build VQ race motors it's known that the lack of lead content in bearings starts to break down with oil temps above 240. We also know stock oil pan allows oil starve when cars are generating high Gs at high RPMs.

I was very easy on my motor no track events over stock redline and only ran a couple autocrosses with 8000 rpm redline and my rod bearings were shot. That's with a aM performance pan and big oil cooler. My motor felt great too but feeling great and causing real damage to rod bearings aren't too far apart.
