SFZ GT3

Help needed, fast. My brother is close to completing a deal on a really nice C2S and has just received the following DME Range Report. The car is perfect, all records, 16K miles and comes (from a Porsche dealer) with a full 2 year, up to 100K CPO warranty.

Here are the details:

Total hours as of 10/29/13: 443,8h

Range 1 Overspeed Op Hours: 344.5h, # of Ignitions >max: 7157
Range 2 Overspeed Op Hours: 288.7h, # of Ignitions >max: 1625
Range 3 Overspeed Op Hours: 288.7h, # of Ignitions >max: 271
Range 4 Overspeed Op Hours: 288.7h, # of Ignitions >max: 178
Range 5 Overspeed Op Hours: 288.7h, # of Ignitions >max: 125
Range 6 Overspeed Op Hours: 0.000h, # of Ignitions >max: 0

As can be seen it has 1 occurrence that took it into ranges 2-5 at 288 hours. That is almost 200 hours ago. He and i have 2 questions.

First, how concerning is this report as to the health of the engine, and its prospects for long life, and, secondly, would the presence of these revs impact any future claim for engine work even though the car was inspected and certified for CPO with these revs already in its history.

What assurance (other than trust me) can he receive from the dealer or PCNA that this report (absent any future over revs past Range 3) would not have an adverse effect on future engine claims during the term of the CPO warranty.

Any and all response and guidance based on actual experience would be MUCH appreciated. TIA from both Frank and me.

Sorry, but the car isn't perfect. Looks like somebody did a major money shift. It looks like it happened awhile ago but I'd walk. At that rpm you put the engine through some serious stress. Could be fine but not for my
Money.

I'm shocked the dealer will cpo it as that's usually grounds for PCNA to deny a claim.

My understanding of these reports is the # in the readout is the number of ignitions in any particular range.
This certainly has the appearance of a missed shift, but he didn't hit range 6, and the motor spent about 40 revolutions (125/3 ignitions in one revolution) in range 5.
It wasn't over revved very long, and the rest of the driving appears to be in Range 1.
You have the comfort of the CPO. Buy it and drive the hell out of it before the warranty expires!

Have them attach the DME to the CPO paperwork showing those revs happened before you got it. Have them sign something to the extent of "previous over rev will not effect warranty claims"

Thanks guys. My brother is on travel til later tonight. Hopefully this deal will happen and it will be good, but caution is appropriate considering the consequences.

BTW, it is a 6 spd, MT, no evidence of track setup, but of course 5th to 2nd downshift can happen anywhere!

Thanks RennList posters, I am Steve's brother who started this thread.
I did talk to the dealer and he will attach the DME read out to the Bill of Sale and reference it on the CPO .
BY MY MATH, 40 revs at 8000 rpm lasted 1/200 of a minute, or about a third of a second, is this enough to be concerned about?
Thanks for any info or advice.

I did a miss shift in my 997 on the track, let the clutch out but depressed quickly and before all the way out, I'm sure a DME will show rev type 3-5 but the car is running strong 1.5 years later. No issue.
Did another in my 996 severe enough where the rear pulley came off.
The engine in these cars are very strong.
For peace if mind, do a leak down and compression test.
Enjoy the car and make sure you do take it to the rev limiter often.

Thanks tagvem, I agree, the car has 150+ hours since the event, no issues.
Will post info here when/if the deal happens!

They will decline a CPO claim if it occurred in the past 50hrs, so you'll be covered.

I had the same issue on a 2011 997.2 GTS. PPI readout had a similar number of overrev's, good time since the occurnace and I walked and bought another car, one I have now. The dealer said Porsche will honor the CPO and they would attach the DME to my CPO warranty.... The car drove fine felt fine.... the issue is on the next sale IMHO...

With the dollars involved it is not worth the risk, while the miss shift was a "long time ago" it will lessen the value on a resale. I did not want to explain it to a buyer and take the discount...

There are lots of good cars out there, move on, just my opinion though.

That money shift was done 155 hrs ago on an engine with 443 hrs... on the plus side that's good as any residual issues should have shown up by now. Does the p-dealer have all the service records... any indication of engine related work? Definitely get a thorough PPI by a reputable Indy shop. Per my SA PCNA may deny engine service due to over revs beyond range 2... so don't believe the p-dealer even if they CPO the car with the DME report attached. We've seen enough examples of pencil whipped CPO's to not take the word of a p-dealer in writing or otherwise. https://rennlist.com/forums/997-foru...-poor-car.html

FWIW, in the case of my CPO'd car... the p-dealer insisted that a PPI was unnecessary as their 100something point inspection passed with flying color and that I was covered by the original warranty and CPO. Well... my Indy discovered a leaking RMS and a broken tailpipe. I still purchased the car but provided they addressed both issues as a condition of sale. Better to be safe upfront then having to deal with potential litigation afterwards to make a deal right . Don't believe the p-dealer even if they give you something in writing re the over revs. After all it's PCNA that makes the call not the p-dealer re coverage and we know that in this case the p-dealer is doing something unusual. GL and keep us posted.

Pardon my ignorance, but how does one get an over rev in 5th, or am I not reading it properly?

LexVan

It's not an over-rev in 5th gear, it's an over-rev in Range #5 (8,400-9,500 RPM).
