Porsche does not disclose any information on what occurs outside of range 1 and does not have a defined range for rpm. Every engine may have a different 2–6 range because a GT3 engine functions differently than a regular Carrera engine and will have a different range. In essence, Range 1 is when the engine reaches the rev restriction. Nobody would find it objectionable if a number in the range of 1 had a million. Range 2 is likewise regarded as being within the safe operating area. Anything beyond range 2 becomes quite hazy.
Things start to go south in Range 3. Ranges 2 through 6 represent mechanical overrevving of the engine. This results from shifting into a lower gear at a faster pace. According to the 2 and 3 range in your report, they both occurred at roughly the same time. It appears that the incident occurred roughly 60 operating hours ago. It wouldn’t be a big deal if the engine was still in good shape and the oil and oil filter checked out as clean with no extra metal.
The number of ignitions that are now displayed represents the number of times a spark plug has ignited without a fuel injector operating. The longer it has been in that rpm range, the greater the number.
Porsche actually has new guidelines for what it will and won’t certify for a used car. For any vehicle that has been spun past range 2, they want to see the oil filter torn apart and, in my opinion, an oil analysis. The length of time since the incident also has a significant impact because it is another way to assess whether any internal harm was done. Later in the day, I will review a certified checklist because my memory of that information isn’t quite accurate because it is still rather recent. Prior to the adjustment, anything with a range of 3 or lower was deemed safe and qualified for certification.
Porsche does not post information on this anywhere because these numbers were never intended for consumer usage and are essentially simply supposed to be a means for Porsche to deny warranty work for misused engines. Even the PCNA training division won’t provide technicians with specific information on this outside of what I’ve already stated. Anyone who asserts to have established RPM values for every ignition range is inventing figures.
