If PAG has confidence that this is a fluke incidence, and not a safety concern, then something like a 10yr/100k engine warranty to please the customer base may be needed.
10yr/100K warranty on a car driven for much of its life like this one?I am referring to the OP's track video, which by the way, looked like really excellent driving. I wondered as I watched the video how long my GTS engine would last if it were constantly run at 6.7 to 7.7K RPMs. Race engines are built to, well race, and they only last a few hundred hours at best. How long is it reasonable to expect any engine to last when run like this?

Great point. Not long.

At at what point does PCNA differentiate between an occasional "weekend DE" guy and a heavy track user for warranty coverage??

The rebuild interval of the 991.2 GT3 Cup factory race cars is 100 hours for the coming season (this is twice as long as the previous year for the Cup, I believe). These cars are driven close to redline (8,500 rpm) almost continuously for their lifespan.

Didn't a few of those Cup cars go boom at La Mans this year? And the ones I saw running at Road America in the IMSA WeathetTech races this August were not competitive.

The new 991.2 Cup has not raced yet, afaik. I think it will race in the 2017 season (including Le Mans). So if you saw failures last year, those were only good for 50 hours. Not sure if they had reached that point or not when it happened. Hopefully new ones live up to the hype (street versions too).

See my attachments in the post 2 places above...

Good point. And I'll stop going so far off topic now. Sorry to the OP.

Cup doesn't race in any marquee series, apart from - arguably - Supercup, which is a spec series. The cups did race at Road America in a support series.

2016 engines:

Cup - Mezger
GT3R (GT3 spec) - DFI
GT3 RSR - Mezger

Both factory GTE Pro RSRs experienced terminal failures at Le Mans, and one did in 2015 as well.

2017 engines:

All DFI

From another thread...

Major German style design flaw: high pressure oil pump right near a catalytic converter.

Reading this thread is pretty disheartening. I wonder if Porsche NA actively tracks threads like these.

Marv!!! Where have you been??

Yes, they ARE reading MARV. They lurk around doing undercover work and voyuerism. They are very interested in what goes on here.

Rich. I suspect you know already if it was a rod failure. You will have seen a hole in the lower case and alot of oil residue?

Marv .... don't want to go off topic here. Interested in hearing more. Maybe start a "What's been up with Marv" post?

We can discuss all sorts of things there.

Exactly. And 100 hours is not when the race engine is expected self-destruct - the probability of them going boom may increase by just a few % and performance may go down immeasurably, both of which is unacceptable in a car that has to win races but not end of the world in a DE car. Losing an engine at this few track miles is not something we should expect from a GT3. If it is, I'm switching brands.
