What caused the initial burned bearing/broken rod? Stretched/failed rod bolt? Have an over-rev previously? How many hours back?

If you don't mind, let us know as a data point....

BTW, nice upgrade on the ride!

Was an early 2005 3.8 I had actually proactively put in the ceramic IMS bearing a year earlier. I think that may be the only part that survived! That all being said, I did have quite a few track days on the engine, but it still shouldn’t have gone like it did. Also Porsche shouldn’t have such an expensive engine replacement program when it comes to rejecting cores. Makes me want to leave Porsche and go back to Corvette.

The car now has a 07 3.6 and honestly, this may sound strange, it is only about 2 seconds slower around Sebring. (Maybe even less because the one time I’ve taken it out my rear tires were pretty much shot) I actually want to take it out again with the 3.6 with new tires and see what the real difference was and post the results here.

Sux. perhaps posting in the GT3 would get more eyeballs??

An analysis is a good suggestion.
Can you tell if the "*****" are organic or inorganic? If they seem to be organic, you could send them to Blackstone and see if they can break down the components http://www.blackstone-labs.com/ .

oil and coolant materials - probably post rod failure.
my 2 cents
