Did some more online digging, that shows Range 1-3 as essentially normal on the Cayman. Above range 3 and you start running in the possibility of mechanical damage.

1-3 being into fuel cutoff, however above that is mechanical over-revving of the engine exceeding approximately 7900 rpm.

BTW - Do appreciate the replies, and am passing all info along to my friend. He's been searching for a bit, and has sent three cars for PPI's during the last six months. Two out of town, and now this one near home. Says car is very clean overall, one owner...obviously one of the biggest concerns on this rev report is that the over-rev was so recent in the car's history.

One he'd checked out before this, had considerably more overruns, but they were long in the vehicles past, and the PPI inspector stated that he had no concerns on the reliability of the engine moving forward considering the history of engine since the over rev, and the total time on the engine.

We shall see what he does.
