Dam that sucks, didnt really think that it was possible.

Recent reformulation of oils don't help much. The EPA had sulfur compounds removed a couple years ago, and more recently zinc. Check the current June issue of Hot Rod (I think?) for an article on cam failure from such oil, and a few oils ranked by zinc content.
But, hey, we were revving stock B16 cams to 9500. Our rationale was that hotrex wasn't man enough to, so we needed to step up and be role models. |

Fuel follows torque, then 6500 tq peak sounds about right.

Yeah the sulfur is a must-have anti-galling material for high pressure friction surfaces. Hence why gear oil has so much sulfur in it.
