Reduced engine performance problem

Cam Sensor
The first time it happened, it ended up being a faulty cam sensor. They replaced it and after driving back from Sarasota, it ran fine for one full day. Then, it went into limp mode again showing the same, reduced performance warning. So, we too it off the track and left it overnight. When I went to get it over to a local dealership to await the flatbed, I had similar issues w/ the lift when when it was still working. Then, only a few minutes into my drive, the engine temp went out. Then, the engine fans went crazy thinking the car was overheating?
I'm about to catch flight back home, so waiting to hear what status of my car is??
On a side note, this car on track is absolutely unbelievable… when it' running.

I'm flying home from Sebring after Winterfest and had the same problem.

Well, my mechanic just called: faulty cam shaft position sesnsor. He thinks it's a fluke thing and had nothiong to do with track or gas quality. Now that it happened to you, make me wonder if it's a bad batch or was it the part that delayed production or what? Only time will tell.
Sorry about your trouble!

Sorry to hear these troubles guys. Hope they figure this out quickly. Problem is most these mechanics have not been properly trained. I talked to our master mechanics at our dealer and they are a big dealer around here and he said he just came back from training and there was no GT3 at trainng site for them to work on. He was pretty disappointed. It was all manual and no hands on. I bet they will ask German engineers to fly over for this one and they better do it quickly. Frankly I be pissed.

I ran with you on the track a couple of times, the car looks beautiful.
Not sure about your experience level, but I think you were certainly beating the living daylights out of the car in the solo group.
I never saw you off the track and I was parked in a the far away corner of the paddock.
Thank you so much for sharing; Your report makes me so angry with Porsche...What a way to destroy your weekend.
We laugh and take bets, make jokes when we see the Lambo's Ferrari's, GTR's, BMW M etc show up because we know they don't last and we're very confident in our old GT3's.
BTW, we ran easy 10 hours of track time in the RSA and other guys in their high mileage GT3' with nothing more than adding gas tires, gas and pads..
Now you confirm our fears with the first 991 GT3 I see on track and iyt was not even hot!
Please keep us posted.
Just another fast car that's not track proven and not track worthy until proven otherwise...

I did not say it blew up, I just quoted the owners comments and concluded that his weekend got more or less ruined by an unreliable unproven on the track car.
Now its just like all the others I'm afraid
I would have given it right back to the dealer and will if that happens to me on my first weekend at the track... I get really cranky when I make time with a lot of effort to be at a track and the car lets me down. specially a shiny new one.

I'm going to have some fun and speculate here.
The 997.2 RS had a compression ratio of 12.2:1 which is very high for a street motor that runs on pump gas by default.
As if this wasn't crazy enough, the 997.3 had it raised again to 12.6:1. Andreas Preunninger himself said, “We played with ratios as high as 13.0:1. However, we encountered some detonation at this level, so we settled on 12.6:1"
With the 991's DFI and a few other tricks, the compression ratio is 12.9:1 (!). Anyone who has a bit of engine building knowledge knows this is insanely high for pump gas.
Throw in the 9,000 RPM redline and a splash of cheap fuel and we got a recipe for disaster.
ECU's these days are very advanced and I'm sure the knock sensor(s) in the 9A1 has very high resolution but that just means she's going to go to limp mode really easily which I suppose is better than throwing a connecting rod out of the block!

I can hear Porsche saying, "Did you read the manual? We warned against sustained high rev's during the break-in period."
My response would be go **** yourselves and fix the damn car!
