Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

And ultimately , the final exam: 90 minutes on the Autobahn, where every 911 off the assembly line must satisfy perhaps the worlds most demanding , and some say most fortunate, driver- a Porsche test driver."
Leading evidence: 'Test rigorously---on the bench' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Test driver."' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

This could explain a lot with these engines, would be a neat graph to see trans bearings and IMS failures vs test drivers name.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Three things that make me cringe I learned from my 1999 Dealer brochure that just came in. And I quote from page 15
"Each engine is tested rigorously---on the bench for up to half an hour, with a full minute nonstop at redline!!!!!!!!!
Then a rolling road test. And ultimately , the final exam: 90 minutes on the Autobahn, where every 911 off the assembly line must satisfy perhaps the worlds most demanding , and some say most fortunate, driver- a Porsche test driver."
"Each new 911 must slow from 90% of its top speed to 62mph 25 times. Consecutively. Without suffering significant brake fade."
1. So there are two schools of thought on breaking in a motor, apparently Porsche takes the rough road.
2. Some yahoo was given the keys to my car for 90 minutes at unlimited speeds when it had no miles and the crap was beaten out of it and the factory sanctions it.
3. Our cars are place under load to 156.6mph 25 times in a row when they are brand new and the brake pads are not broken in any way I have ever read about. There would be no reason to try and break in your new Porsche when you received it, because the darn thing is beat all to heck anyway.
This could explain a lot with these engines, would be a neat graph to see trans bearings and IMS failures vs test drivers name.

There are indeed different schools of thought on the topic. I agree with Porsche's technique, and I've rebuilt motors that after thousands of track and tens of thousands of road miles are still at factory spec compression and leakdown-or above... They're meant to be driven, and going to redline or staying under load is not outside the design parameters IMO, nor Porsche's, obviously.
