Default Does this PPI concern you?

So i have been lingering for quite some time on the forums but haven't posted or even made a account today. I have been absorbing a lot of information and feel like i have a good grasp on what to look for when buying a car. My budget for a car was around 40k. I thought for sure i was going to get a 997.1s with the current market.This morning a 2010 977.2 Carerra came up. A little higher of mileage but not too bad at 92k. Car seems to have some imperfections in the paint. The PPI does have some over revs that concern me. Here is the PPI.

I’d dig a bit deeper on the over rev report. It is concerning at first glance, but with each range it logs the number of hours on the engine when an over range event last occurred in each range. The DME also indicates the number of hours on the engine. If the car runs fine and it’s been tens of hours + since the range 4 and 5 ignitions were logged, it could be fine. At the same time that report will also be a question mark for resale down the road.

That’s not much of a PPI. Did they provide a checklist?

The car has 92k miles. Here is the rest of the check list. Things that they marked wrong they are replacing.

Price seems right to me if it runs and drives well.

Yea car is listed at 41.8k. Right in my price range and the market for 997.2’s with a MT is insane. It’s for some rock chips here or there but that doesn’t bother me. I’m buying the car to be driven. Just the over rev in range 4 and 5 that bother me that’s it.

Personally I would not worry about it..... especially if the overrev happened early enough and the car runs well and rest checks out.

Also something does not make sense. if range 3 should not be lower then 4 and 5 as you'd have to pass those ranges.



This is what I mean:

Agreed, I think it's mechanically impossible to have more ignitions in an upper range.

I believe Porsche uses a rule of 40 hours since infraction.

Thanks for the words of encouragement. I’m gonna FaceTime the seller here soon to go over the car again on the phone. I’ll ask him specifically about it. Worst case I’ll call the PPI place cuz the seller is the one that paid for it. Hopefully getting my first porshe by the end of the week!

Did the seller have the PPI done before you showed interest or are you reviewing it live with him? If it’s the former I’d suggest still having your own done for peace of mind and you will go in eyes wide open.

OK, so I just wanna chime in regarding the over-rev report that does not make a lot of sense. Why does it have more ignitions in the higher ranges than in the lower????

It's true. This can happen. I just learned about this recently myself (and here I thought I was the kingdingaling of the over-rev reports). I should of asked my wife, she seems to know everything...LOL

What happens is that the vehicle only records the ignitions in a particular range that it's in once the alarm for the "abuse" goes off (enters 7300 RPM range). It does not keep recording the previous ranges once the crank shift revolutions get out of it. So, if you rev the car too fast and hold it there like an id##t bouncing off the rev limiter, the ignitions in the lower ranges will be lower as the crank shaft revolutions went through it too fast, and since the id##t behind the wheel is holding the gas pedal and bouncing off the limiter, the higher range ignitions will show up as more. Get the picture? It's called abuse and it voids the warranty.

Porsche did this as this kind of data tells a story......this DME report tells (me personally) the following:




Range 3 is the story teller here. Don't worry about range 1 (this guy knew how to drive and shift, as according to the DME report with almost 14 seconds in 7300 RPM - 7500 RPM , he hit the beginning of the rev limiter and backed off quite often). However, he probably gave the car to someone and that someone created this "not so good" report. You are talking a very short time spent in all other ranges. It does not follow the pattern!!!! You would expect a bit more of range 2 (or even range 3) but not 4 and 5.
Range 3 tells me personally that this happened only once.

This report indicates that this probably took place going from 1st into 2nd, where the car has more torque in order to spin the crank shaft WAY TOO FAST and almost jump through range 3 (7700 RPM - 7900 RPM). Or, just revving it in neutral and bouncing off the rev limiter . Which unfortunately is most likely what happened.

This report is good. No mistakes there. It's legit.

Check how many hours was spent in range 5 and make sure it's more than 50. Who knows....ask him if he ever gave the car to his kid who tried to show off in front of his friends by revving the cr##p out of the car in the parking lot?

You got the report...and now you gotta get the story behind it. What happened? Pattern is changed and there must be a reason for it.

I think this is a good car with a single abuse instance. Just make sure there is more than 50 hours past the Range 5 and the engine is running good.

Hope this helps.
And this is me reporting live this Saturday night from my office LOL...cheers!

Thank you Boris! Yes the seller got the PPI done prior. He’s replacing the lower control arms and rear brakes as well. He’s clarifying the over rev report on Monday with the company that did it.


here’s the listing. I got a deposit down on it now. I feel like it’s a good deal given the market. Paint in def has some rock chips in the front clear bra.

The overrev report is useless without the hour tags. I would bet the hour Tage for the overev in rabges 3, 4, and 5 match and were part of the same event. That engine went right past 3 quickly and then stayed in 4 and 5 and why those numbers are higher than three. This was likely a missed shift with full clutch engagement and poor reaction time to realize what happened. If this was recent (50 hours or sooner), I'd walk. If longer than that, the engine likely survived.

Well looks like I’m in the clear. The range 3,4,5 over rev happened at 623 hours all the same. It has 2500 hours on it now. So I think if anything was gonna happen it would of by now 😂
