I read this post over the weekend. It was like reading a tv drama! So pleased porsche saw sense. Surely now you're going to end the story perfectly by going for the 850 brake upgrade with the money you didn't spend!!
I am looking at pricing up upgrading to GT2 RS turbos and intercoolers with upgraded exhaust and clutch which would give me circa 650bhp. No point going 3.8 and 850 unless you need to rebuild the engine as its very very expensive. Truth be told 480bhp is still plenty quick for me so might do all this after the car is no longer eligible for OPC warranty.IMI A said:
Car feels smoother but engine still very tight. Its only after 20,000 miles that these engines really feel run in. I'm not going to take this engine over 6000 rpm this time round to be honest so won't bother with odb etc. You don't really need to take it past 6000rpm in any event as its just as quick without hitting the rev limiter. If you hit the rev limiter hard enough the software registers over revs so best not to - learnt from my mistakes! They've done about 400 miles in the car and said the engine comes run in from Porsche so no need to run in. It was in showroom and I felt my car has far more presence than the 991 and Boxsters it was parked next to. Honestly looks like a refugee from the Nurburgring compared to the newer kit. Should really replace it now but nothing there that really grabs - everythings PDK nowadays!!
The problem I find, even with a Pdk, it spools up so fast that getting the next gear before it hits the limiter is difficult to do on a full on charge!NineExcellence have some well sorted power packages for most budgets and tastes. The quote to take mine to around 588bhp was very competitive considering it included a 100 cell titanium exhaust with a flap that automatically opened above 4000 rpm iirc. Ken attention to detail is legendary.
Very glad this has been resolved, I read through the thread in one go and was starting to think it would go on for ever and get ever more expensive.
I am still not sure from reading it all how Porsche judges how these out of range instances can mean a warranty is paid out on or not. It seems not to be how large the spike is but how recently it happened to when the problem occurred. It cannot be accumulative it seems, though I would have thought accumulative stresses would be the main reason for failure, because they keep selling you the warranty. The problem is that if it is judged mainly on how close the over-rev happened to the failure. Of course it is instantly then fine, but 1 hour, 2 hours, 24 hours, what is the yardstick Porsche use?
A warranty is supposed to be "peace of mind". The OPC warranty is hardly that if people are going to be asking for readouts before they drop the car off for a service, and after .. just in case. Also what happens if you get a couple of spikes? Then you would really start worrying. It seems the OP is no longer going to go near his rev limiter any more just to be sure, a rev limiter he has paid for. Hmmm.
The new 991 GT3 is an interesting read. Rumours were flying last time there was issue with the rods. Now it seems overheating gearboxes on the GT3. As you know they tweaked the PDK speed for the gearbox so it was faster over a standard 991.
Do you remember in the old days when Ferrari's were great but you had to be very brave to buy. I think Porsche are going the same way.
Having said that you can pick up a 996 now for £8k. You could run it and risk it all and just hammer it into the ground and hope you were lucky. I guess Mazda RX8 drivers do same for £1500. Disposable sports cars that are great to drive.
Good luck with your cars may the Gods of doom stay away and enjoy your fantastic cars.

Having said all that I am now looking at this

and thinking it is very nice indeed. They are in my price bracket now. Seems a well written advert too.

Thought it may be interesting for those that ever want to buy an exchange engine to see the warranty bill and actual price of exchange engine from Germany. It will be pretty similar for any Mezger engined car and not sure if there is a large discount on the engine itself as OPC were saying it was £40k for a new engine retail. Pls note they wanted to charge me £7k for the labour so bill would have been £30k inclusive of vat if I had to pay. Porsche warranty get a large discount on the labour element too.

Interesting reason for engine failure. No mention of over-revving.
Glad it's completely sorted
faith in opc restored!
Just to clarify something it was never the OPC's fault the claim was rejected it was Porsche GMBH themselves.Glad it's completely sorted
faith in opc restored!They were just following protocol.
Nothing more they could do and their hands were tied.
But yes it is great that it was changed.
I am not sure if this thread is dormant or not, but I wanted to add my experience with the RR issue just to make people aware of what is out there.
I have a 2008 997TT, which I purchased in the UK in 2011. It came with almost 12 months of Porsche warranty. At the end of the warranty period (September 2012) I took it in to my local OPC to get the warranty extended, or at least approved for warranty extension. The OPC said the warranty would not be extended because it had RR 4, 5, and 6's in the last hour of use. I screamed blue murder because I believed the OPC driver who picked the car up had gone for a "spirited drive" and done a 5th gear to 1st gear down s
t and hit more than 9000RPM. Anyway the OPC flatly denied the driver was responsible and I knew I certainly wasn't responsible for the over revs.
Long story short, and to the credit of the OPC after many weeks of testing, they managed to get the car to log additional RR 4,5 and 6's in the workshop. Yes, under controlled conditions and not being over revved, the car was intermittently logging over revs. They thought this was caused by an incorrect gap setting on the crank angle sensor. So engine was removed and the crank angle sensor adjusted - all under warranty. I thought that was the end of that....
I moved back to Australia at the end of 2012 and brought the car with me........
and then...
Several months ago I started to get the "start rev flair" problem and the "not starting randomly" problem that seems to becoming quite common. When I plugged in the Durametric I found I now have more RR's being logged. I definitely have not over revved the engine.
So I am back to square 1 in trying to solve the start/rev flair/RR issues. I suspect in my case they are somehow related and will post an update if I come up with anything useful.
The main point being if you are getting RR events logged, especially in the 4-6 range and you are absolutely certain you have not gone over 8k or 9k revs, then it may be an ECU glitch, cause yet to be determined.
wish me luck, or if you have an suggestions happy to hear them.

Some more info here. Many 997.1 turbos have this rev flair problem. The joys of turbo ownership.

I had this Imran on my 997.1 Turbo too. It only ever really stopped after the starter motor was changed and at the same time the alternator cable (which I hear can also be a starting issue as it is exposed to the elements and can pick up crud etc) was also sorted - I believe in 2009 Porsche changed the cable to a much more robust design helping to further sort out starting issues especially on starting the engine when hot after a long run etc. That said reading that thread, sounds like that flair up will persist at some point again until you have the gearbox out and the sensor sorted. I got the DME read out of my car just before I sold it and although there were no over revs in 4,5 or 6 there were still a few in 1,2 and 3 which surprised me a little the way I drove and looked after it.
