Mechanical Over-Rev Discussion

They SHALL not sell!!! Lol, so
much wrong information here. We have no proof of anything. It could bounce off the fuel
ignition cut off at redline all day and it will report 1000 R1, what does that mean? Absolutely nothing.
The whole reason for now just R1-3 is just that. Porsche doesn’t care anymore about anything over 9500 and that’s just 500 RPM above redline on a car that we have seen can handle 10k and not have any issues.
What are the concerns here? It’s either toast or not toast. Pistons hit or they didn’t, chain snapped or it didn’t. There is no in between really? Either you scored the cylinder or you didn’t. This is not Schrodingers cat, it’s not both so ****ed and so good.
Also, due to warranty laws, Porsche also can’t just unilaterally void an engine warranty for R3. First thing is engine needs to actually have an issue, second the burden is on Porsche to prove that whatever the issue is was caused specifically by the R3 and nothing else.
These posts are what causes unnecessary confusion and drama.

Yes and no. Sort of. If you have an over-rev Porsche absolutely will try to deny warranty claim UNLESS a certain number of operating hours have passed since the incident. Even if nothing happened to engine during the over rev. A year later, if something breaks, they will blame it on the over-rev if it is under that operating hour threshold. Is it legal? I don't know. Good luck battling a global automotive conglomerate in court though. Maybe they've eased up and only care about certain ranges now. I don't know those details.
No, that’s the thing. Porsche cannot just unilaterally deny the claim without proof that the issue was specifically caused by the over rev. It’s not legal, nothing to battle. It’s actually spelled out in the back of your Warrenty booklet. The burden is on Porsche.
ps, you don’t go to court, you go to arbitration.

Bottom line is, the purchaser has pulled the plug after the inspection report and indicating they would not continue the warranty on the engine.
This report is now stuck to this cars history.
Now a very tricky sale to find for the owner whom had it on SOR.
If something goes wrong, you can bet your *** Porsche won't drop a new engine in there on their dime without a fight.
I wouldn't be rolling the dice on this touring if i was in the market for 2nd hand.

Never had your tongue bitten eating leisurely, so you quite eating ?

Sale vs. Warranty service
I would think there is a huge difference between fixing a customers engine on warranty vs selling a car (especially as a dealer) with a documented severe over rev. Two very different legal situations.

I understand and I hear everyone’s thoughts, I get it.
My issue with that particular car is we don’t know what happened and it appears that it was 1000 revolutions in R1, if that is the case then that means nothing. The car is good to go, even if it was R3 and there was no visible damage after the scope and leak down, than it should still be fine. It’s not automatically branded a void Warrenty because of R3.
Now if the thing is blowing smoke, clunking and fails the visual and leak down and has an R3, that’s a problem. But R1-R3 by itself does not make for a bad engine and voided Warrenty.
Also, with R3 being 9501, 500 RPM above “redline” is not going to harm these engines. It’s basically the same as a cup car and we know those are good to at least 10500 if not more before potential for any damage. Ask any race team mechanic.
These engines are very very robust.

Also, 1000 is the number of ignitions. So this would be 333 revolutions.

Again.
R1: 9001-9251
R2: 9252-9500
R3: 9501 +
Porsche is still telling dealers to treat R3 like a 991.2 R4+, but they are more concerned with the visual scope, compression (no leak down if visual checks) and oil analysis. Their big thing is basically, this is a very robust engine, if you ding it, you will know it.

100% positive it starts at 9001 and the increments have not changed. I thought they would have truncated R1-R6 to the new R1-R3, but from printed reports I’ve seen, it’s the same 250 per range with only three now. They sort of combined how it was in the 996 GT3 (R1/R2) with the 991.1 GT3 R1-R3) and got this new R1-R3 for the 992.1.

Hey everyone
A seller sent me this report on a 2018 gt3 … the range 4 and 5 and 6 are concerning.
if a compression and leak down test pass is this thing still a concern?
any thing else to test for?
pretty concerned a new engine is pretty likely in the future.

what are you worried about?
#73
porsche dealers advise to stay away…
my race mechanic says not necessarily a worry.
40 hours does seem to prove it can run. So not a car to pass on?
recommended testing ?

Are those Porsche dealers trying to sell you a different car?

Perfectly fine.
If it makes you feel better, do a compression, leak down and a visual bore scope, send oil to Blackstone.
It happened a long time ago, if anything was to break, chances are it already would have happened way before 40
additional hours.
These engines are over engineered.
Id buy it!
Ps. Porsche people are the only ones concerned with over rev reports, I’ve never seen anyone ask for one on a manual Ferrari or Lambo or heck any other manual car. The funny thing is, it doesn’t even go to show if the car was abused, it’s literally a snap shot in time.
