That's why,besides price,it never got my attention to seriously consider it...I knew the savings have to come from somewhere...plus the looks...that rear...forget about it...
Back on subject,I'm hopeful...since Porsche caught it in time and doesn't really affect its name...way better than a recall!

True, but Porsche has delved into somewhat new territory with 9K redline, RWS, and PDK in a GT3, so I think that elevates the risk of unforeseen problems in the future.
Speaking of which, what have people heard about durability and overheating of PDK in other Porsches that have been heavily tracked? I don't see many PDK cars at the track, and none that I've seen have had a lot of track miles.

PDK's have been reliable so far with limited and relatively low track times.
Seems to me a temporary Engine "fix" might be to reprogram the GT3 computer lowering the redline to the HP peak of 8,250 RPM until a thoroughly tested solution is found. HP and Torque would remain unchanged, and, with the close ratio gears in the PDK/S Box, an upshift would still put you close to peak torque. I would guess laptimes might not be significantly altered. Personally, I'd trade the sex appeal of a 9,000 RPM screamer for a bulletproof engine any day.

All of Porsche advertising talks about the engine screaming between 8500-9K,can you imagine what a total fiasco would be to change that now?!

Sorry, can't agree with that conclusion. I'm surprised that any company will warranty track usage.
You claim to run 30 days a year. At 200 miles per day, you could have 24,000 track miles on the car before the warranty expired. Would you give somebody a warranty for that kind of use?

As to the rod failures, if true, there's a difference between a design flaw and parts that aren't spec'd adequately. If the problem is related to the former, then we have a problem. OTOH, there's nothing magical about 9K rpm that is beyond the reach of adequately robust parts. Macca is certainly correct when he suggests that components are being upgraded to fix the problem, and it's being dealt with before the cars are in the hands of any customers.
The sky is not falling.....

Mike already pointed out the issues..again:
1. Suppliers didnt deliver what was being asked for
or
2. Porsche´s orginal design with the quality in the parts wasnt there - then they cant fix this properly in 3 month - never. Of course they can deliver something..but whether it would last..not that long probably. And from what I heard, the piston issue is real, engines blew up during testing.
Im wondering now when this engine will show up in racing..I doubt it will be there early next season..I doubted that already before,,,but now I doubt it even more..

The 9K redline has never had much appeal to me. I'd rather give up 1K at the top end to get a better torque curve across the rev range. And that makes even more sense for the majority of people who'll be mainly driving the car on the street.

You don't have to go too fast,you can do it from 2nd to 3rd or 3rd to 4th...What puzzles me is how come they didn't discover this issue during testing?! I see teaser videos all the time from Porsche during testing...from freezing temperatures to the desert heat,they register thousands of miles and none of these problems occurred?!

I think this is fantastic news ab the high rpm issues. Now Porsche can't back down from their 9k rev line, and they can't jack up the price on 2014 cars, so they will have to introduce costly Ti upgrades which normally might be reserved for a racing engine. This will take the engine from being over stressed to relatively under stressed, and we'll get some exotic parts for free.
I'm sure there will be a significant price hikes later on so they can recoup from this blunder.. But this is really good news for those of us on the list... How often does his happen where mAjor engine issues are caught so early? We're a lucky bunch of fokkers we are!

I believe that you mentioned hearing that the new motor will not be from the current 991 GT3. I don't know about that, but I wonder what it would be? Further, why develop this engine to use in a relative handful of GT3's in 2014 and, maybe, 2015?

That's interesting. With the PDK they can absolutely guarantee the motor will never see 10k...
Are they building it for 10k as an additional margin of safety even though they don't need it? For future upgrade potential? For marketing?
A manual transmission car does require an additional margin of safety. Just sayin...

My information is that the RSR will continue with the current engine until the 2015 season when it will be replaced with a DFI motor.

What Im trying to say, and at the same time I do hope this happens, Porsche needs a B8 - otherwise this case is lost. Manthey developped a 4.4L based on the current 991 RSR engine for the VLN series in Germany..he said that just by the gained torque he was able to catch up significantly.
Just to be clear, in order for Porsche to win in the GTclass (except the lucky win in Le Mans the season was more or less a disappointment) they should not continue with the Mezger engine, but it seems they have no alternative left for the moment. The current regulations are clearly pro 8 Cylinder..a 6 Cylinder DFI or Mezger...wont solve the problem. This is my humble opinion..time will tell..
We should all pray this would happen..because I dont see Porsche continueing like this for years ...

I disagree here. My turbo BMW and Aston annoy the crap out of me with their low rev limits. The 9k redline is of great appeal.
