Looking at a 997.1. The seller did a PPI 2.5 yrs ago and here's the data:

Number of ignitions in Range 1: 22014 - 1090.3h
...Range 2: 1524 - 1087.2h
...Range 3: 505 - 1087.2h
...Range 4: 25 - 52.9h
...Range 5: 0
...Range 6: 0

Keeping in mind this was from about 10k miles ago so presumably the hrs since Range 4 is longer than the 52.9h stated.

Thoughts? (besides doing another report)

Honestly a report from 2.5 years ago isn’t helpful to you. Looks like one bad shift on that report, if it’s 10k miles ago that shift should be fine. What happened since then is the most important info. Get the DME and a full PPI if the car fits your criteria.

Yeah, that report is useless, except for the fact that you can now see how the owner you'll be buying the car from has driven it since you have a report from before his ownership and will have a current one (once you get it) to see what has changed.

Thank you. I'm planning on getting a PPI. I am more asking if Range 4 over-revs should be a deal breaker?

Petza914

Not from that long ago. We like to see 50-100 hours since a higher range overev event and you have way more than that.

The range 4 isn't real worrisome by itself being a low number and a long time ago. That's a lot of range 1 overevs relative to what is common. Has it seen significant track time or hard street use? People can say these cars are made for that all they'd like, but I'd still rather put the overevs on myself than buy a car someone else drove pretty hard, depending of course on your budget and whether the price reflects what you know about the car.

BrantyB

Thank you for the feedback; and I though that the Range 1 seems a bit beyond "normal" as well. The current owner says he doesn't track the car, and doing the operating hrs & mileage math, the 1090hrs would be before he owned the car. The Range 4 was under his ownership.

C4SDayton

I believe you are misreading the report, which was before the current owner had it. The range 4 revs occurred with 52.9 hours of engine run time, so early in first ownership. The last overrev occurred at 1090 hours, likely soon before the current owner bought the car. The total hours isn't on what you gave us but the range 4 occurred about 1040 hrs before the last range 1 occurred.

BrantyB

Oh. I was under the impression the hrs listed was hours since event occurred; I guess I'm wrong. In that case you're correct that almost all the over-revs occurred under the previous owner, and that person looks like they tracked the car. The total operating hours on the report is 1837.

Yep, the incident hours is the running engine count since initialization of the DME (the birth of your car).

Another useful bit from the data is the average speed of the vehicle over its lifetime. Typical values are 30-35mph, I think. Much higher would have to be exclusive track time, much lower would be a lot of crawling traffic.

BrantyB

Yeah, I knew that part. PPI mileage was 52200 with 1837hrs = 28mph, so fairly typical driving.

low numbers in any range means the rpms just "kissed" or "brushed" the bottom of the range. We are talking milliseconds with low numbers. The longer or deeper the time spent in the range the more ignition counts. A small number in range 5 would not necessarily scare me either as long as they were 100+ hours since the last incident. Get the latest and greatest report and we can take another look to analyze

BrantyB

Thank you for all your thoughts, it was helpful to me to get others' perspective. I decided to pass on the car; after thinking about it more just didn't feel right to me.
