Help with interpreting rev ranges?
Discussion
OPC have just informed me that the used 997 I am collecting tomorrow has been into rev range 4, which prompted them to do a full cylinder compression check before taking it into stock. it checked out fine. His view was that it was likely to have been caused by a missed gear.
They also explained that at 3 or below they wouldn't even bother to check, while at 5 or 6 they would expect to find damage.
Should I be at all concerned about the reading of 4? Two year OPC warranty etc etc??

Hi,
Get a printout of it with date that it was printed. I would also get a letter confirming that Porsche have accepted that all is well and the engine is covered under their warranty. Just to be on the safe side.
I would not collect the vehicle until I had that documentation.

Thanks Mike. OPC have confirmed verbally that it will be fully warranted, I will double check tomorrow and make sure they haven't slipped in any exclusion as a result of what they've found. Apparently the OPC have spent £5,500 (cost to them) in prepping the vehicle, and I hope they wouldn't have spent that much if they weren't 100% happy with the car.Get a printout of it with date that it was printed.

This ^ if you end up taking it to another OPC they might not be so accomodating without any proofGet a printout of it with date that it was printed.

This is interesting, as my OPC told me they don't touch cars with any over-revs, so not a uniform response across the network?
Deffo get the dated printout, written confirmation that the spike has been accepted and you are covered, as in 2 years you may still have the car and want to renew the warranty?

with range 4, there should also be range 3 overrevs. If there aren't, it could be an electrical fault

A rev range of 4, that appears to be 7900-8400rpm? I wouldn't buy it, there are so many cars available I would move on.
As per my thread (linked above), it would depend on the number of ignitions in rev range 4. A low number likely means a computer glitch, tens or hundreds of ignitions and I'd steer well clear!

If the engine goes bang, you need this in writing, as it's NOT the OPC which issues the warranty, it's an insurance company, and the OPC have NO RIGHT to amend the contract between you and the insurance company.
You need a written letter of indemnity from OPC.
Folks
I've had a chat with one of the most respected indies in the business who was kind enough to speak to me about is, and he was clear that this would not be an issue in taking the car on for resale, especially if 100 operating hours had passed since the last 'incident', after which the risk of a consequential failure is miniscule.
OPC have raised the bar on these issues recently, which is why rev range 4 is now checked out as part of the 111 point check; until recently it wasn't considered worthy of concern.
Anyway, I am satisfied, I will have my two year OPC warranty, and I can't wait to get my hands on the car in the morning! Watch out tomorrow on the M25/M1 for a black 997 and a driver with a very big grin!

No chance.
Ask the fellow on here whose Turbo engine popped a while after some dipstick over revved it on a track day.

That was not what you orinally asked, you never mentioned buying the car back for re-sale... that has nothing to do with your OPC warranty question...?I've had a chat with one of the most respected indies in the business who was kind enough to speak to me about is, and he was clear that this would not be an issue in taking the car on for resale, especially if 100 operating hours had passed since the last 'incident', after which the risk of a consequential failure is miniscule.

So when it does go bang, at least you can get the indy to explain to Porsche why you deserve the warranty... Cover your ASS !

Whatever the reason, damage or no damage, warranty or no warranty, it'll be a bu66er to sell, come resale. I wouldn't buy it from you!
Exactly. You have recourse potentially but the guy buying from your doesn't. I'd get another that has not been over revved no matter how much in love you are!SteveM46 said:

I thought a general check was made of _any_ overrevs and the customer advised of all levels - that's what happened when I had mine done, albeit a few years ago now. I can't see the likes of Henry or Joel being happy to buy in a car that's being overreved - however long ago in the past - when you come to sell it. Those sort of dealers pride themselves on the providence of the cars they sell, as you can tell by their adverts and comments on here. Beware....

That's a bit late in the day, isn't it? Nice of them not to tell you sooner, especially if they knew that when they took it in. Suppose the OPC wants to leave it to the last minute so you don't change your mind.... I smell a rat.Soovy said:

Afternoon gents. Guessing you're referring to my car soovy. Less than 1/10 of a second overrev activity in 8 years/55k miles and the timing chain went 40 hours after the over rev incident. A bit of maths puts the overrev incident back to a VMAX airfield day when six other people drove the car whilst I was driving their cars. A few months later I found out my car was seen spinning that day. I had to pay for an engine from Porsche which they discounted by 20% and my OPC did me a discounted labour rate. Still cost me the wrong side of £20k though. Full details in my profile.To the OP. I'd walk away, would not pass go, would not put down a £200 deposit! Get a car which is overrev clear or when you come to resell the car too many people will walk away.

Yeah. 40 hours later. £20k damage.
OP - WALK AWAY. NO, RUN.
