Looked at a 997 Turbo for sale today, which showed an over rev in range 4 only 4 hrs ago.
It was traded in at an OPC, and was probably a last over spirted drive before he traded it.
The OPC have done their nescessary checks, contacted Reading, who have said there is no problem and have allowed the 2yr extended waranty.

Just wanted to know your thoughts if you think it's ok to purchase. Thanks.

 
If there willing to warranty the car then there shouldn't be anything to worry about.
Tanya and I have a over rev in range 4 when we bought ours from Exeter OPC,done 22500 miles since with no issue's

No problem at all [:)]

In order to issue a warranty, they will have pressure tested all the cylinders and sent an analysis of the engine oil to Stuttgart (with confirmation back that all is ok). Costly for the owner of the car (and don't I know it !!) but absolute peace of mind for the next owner.

Previous to last year, over rev in range 4 was acceptable without all these checks.
 
Porsche cars now seem to have a little bee in the bonnet about over revs at the moment.
Like Doug I've just been through the over-rev situation and know there's nothing wrong with my cars performance ... it's also in warranty.

Quite a good colour that one... [;)]
 
being a complete newbie , I am interested in this over rev ?? does this mean hitting the limiter or what is it referring too, also , can a PDK box , have over rev if never put into manual mode,
could well be a dumb question, ?? thanks any advice is always appreciated [:)]
 
The limiter doesn't operate on down-shifts, so it becomes possible to "buzz" the engine.

This is not possible with PDK transmission since the system will not allow a shift into too low a gear.

Clive.

Oh yes it is!!!
My local PC have told me that it is possible to buzz the engine with PDK or the old Tiptronic. It was explained how but not sure I understood it.
 
Thanks Clive ,
I understand now , with the PDK that you wouldnt be able to miss a gear in theory, as described by the guy's using manual, just filling my brains with al this information , cheers
 
It shouldn't be possible to over rev on a down shift with PDK but you can get (momentary) range 1 and 2 overrevs changing up in manual or Sport +. Most likely happened to mine on track though......[;)]
For info

i've encountered this a few times - usually in 2nd gear when hooning it past some jackass - the boost comes in and the car bangs into the limiter in second (in manual mode) before you have time to flick the paddle. Cue hanging in the seat belt momentarily as the car runs out of acceleration, and me looking like a Muppet.
 
yesterday was mucking about with a 430 on a nice bit of road, hit the limiter once while chaning up from 3rd to 4th coming out of a bend, what sort of issues will that have caused?
 
You were still accelerating when you hit the 3rd gear rev limit on a public road in a 911 Turbo? Where were you? On an autobahn?
 
The official information, courtesy of Exeter OPC, is as follows:-

Over-revving in ranges 1 to 3 is perfectly O.K, over-revs in the range 4 to 6 are potentially engine damaging.

Alan is correct in saying it is possible to over rev the engine on PDK in manual with sports/sport plus mode on.

The PDK can also be ove- revved in certain conditions, for example, coming down a steep incline very quickly in low gear with the momentum and mass weight of the vehicle causing an over-rev situation.

Regards,

Clive.

 
For further clarifcation, whilst it's possible to record an over-rev. situation in sport/sport+ in PDK manual mode, Exeter OPC report they have never seen anything above level 2 - even on hard tracked cars, and this is within the acceptable range for Porsche.

Would it not be possible to over rev a PDK if it was put into neutral and then revved ?

Engine revs would be governed by the rev. limiter.
