Default Question: Range 5 over-rev on missed shift

Question: Range 5 over-rev on missed shift

--------------------------------------------------------------------------------

Hello. Can anyone tell me how significant a range 5 over-rev from a missed shift is? I am looking at a 2008 Turbo Cab with 4500 miles as a DD. It has bumped the rev limiter several times on the way up, but has a range 5 overrev from missed shift. Should I be concerned? I also posted this on the Turbo forum.

BTW, my second choice is the GTS cab--thoughts?

And thanks for all the responses on the Spyder vs. 911 Cab. Drove both with my wife, and the hair-blowing-around was ever present on the Boxster, but not the 911. Both had wind blocks.

From the tech info of PIWIS


..
Rev range 5:
⇒ Maximum permitted engine speed very clearly exceeded; engine damage very probable.
Rev range 6:
⇒ Engine damage has generally occurred.



Proceed with caution..

How many ignition counts? Do you know for a fact that it was a mis-shift?

Reason I'm asking is, hasn't it been seen where the upper ranges had a count of 1 ignition that turned out to be a nuisance (false) indication?

If low count, get a compression and leak-down test done to ascertain no bent valves (that is the risk if the valves float and hit at the upper limits).

If it checks out good, I would be ok with it, but you can use it to negotiate.

GTS is great value, but so should a 08 TT.

All IMHO of course.

Yes, could be warranty issues down the road so make sure all is well documented by selling dealer, assuming dealership and not private sale.

Good luck.

If I were to buy the car, this range 5 over-rev problem will become mine in the future when I need any warranty repair or need to sell the car. Why open that can of worm?

Just move on and shop for another car, there are many choices in this market.

I would guess that any potential buyer 'could' apply a massive potential discount to that car - you checked, others might not - move on. My guess is that the discount should be 80% of the cost of 100% fixing the engine.

+1, when does the current warranty expire, or has it already done so?

Also are there any maintainence records for the car available?

Also +1 on previous PPI engine tests

having popped a gemballa 2001 turbo myself (spun #3 bearing) and watching my best friend pop a stock 2006 turbo (case ventilation) both at the track while both were under warranty and not abused -- I would move along quickly. Keep looking unless the price is $35,000 under book -- and you have $35,000 in a rainy day account. I think TKerrMD had a similar situation also if I recall but that was long ago.

Given the mechanical scenario as described, I like axhoaxho's answer — esp. since the usual PPI tests won't reveal rod bolts that stretched a bit and are no longer torqued to spec, and by how much.

FWIW:
-I was surprised by how much I liked the 997-1 Turbo Cab after panning the 997-1 Turbo coupe for crap damping and messy, clumsy handling. It's a very fun car, something of a guilty pleasure in my eyes.
-Just spent two days/700~ miles in a GTS Cabrio in Central California and was shocked — shocked! — by how good that car is. One of the best-handling do-anything 911s I've ever driven. Powerkit 3.8 is greeeeeaaat, too.

Were it me, I'd be getting a new GTS over a used Turbo with or without a story.

I could well believe it Pete ... GTS is a pretty nice package!

It is uncommon for a good driver over rev bad enought for damage. (DRIVER A) Some / a few good drivers might over rev by mistake. What is far more common (DRIVER B) is a guy who is hard on the equipment and rough with the clutch and trans to make this error. If you are positive the damage was done by a driver A maybee this is an ok car. If it was a driver B then this could be the first of many red flags.

If they won't / can't CPO it, move on. I'm sure you'd rather be driving the car than having it in the shop being fixed regardless of price.

Thanks all for the advice. The dealer is getting a GTS in next week, and I will drive that first. I am thinking a new GTS is going to be my next car. I will pass on the #5 over-rev.
