Just ran an overrev report..
#16
I love how some people run for the hills when they PPI a 997 and it has some ancient range 4s on it, but yet virtually every other manual vehicle they've ever bought could have had 3 money shifts in the last 10 miles and they'd be none the wiser.
I assume Porsche included the rev report as a way to deny warranty claims but for all the overhyped heartburn they cause I wish they hadn't.

As stated many times, this rev counter is far from accurate. The ignition ranges simply do not add up to what actually occurs when driving the car. I've gone out and documented the ignitions, done a log to 7k rpm, and then see increase in range 4s, when then highest the car ever revved was 69xx as reported by the ECU.
Yup, an over-squared Mezger engine (large bore, small stroke) with a low 6,800 rev-limit, over-revs for our car are ridiculously over exaggerated. If we're talking GT3 where range 4+ is 10k+, that might be a different story. Too bad there's no over-rev reports on the over priced air-cooled Porsches...
EXACTLY & agreed with what all the attached said!!
Do a leak down test and if all is well, then nothing is wrong with the motor period.
Only in the 911 crowd man have I experience this phenomena of over revs .... If the motor itself that is IN FRONT of you checks out well, leak down and compression test (if you must) then all is well with the motor.
