    Re: GT3 engine issues again?

    ADias:

    Doesn't this suggest that the rev limiter should be 8kRPM (or lower)?

    Seems that 9k may have been too much for the 3.8L, but after much investigation it seems Porsche thinks 8,500 rpm is the safe limit for 100 hours of top performance while racing (for the long-stroke 4.0L)

    However, there is also evidence that the high redline was not the reason for the failures, but it did hasten their manifestation.

    Re: GT3 engine issues again?

    Remember that piston speed is a factor there.. 9k on the 3.8 is equivalent to 8.6 or something on the longer-stroke 4.0.

    Re Grant: 100h of racing is pretty typical, but... racing engines are rebuilt at about those many hours. :)

    Yeah, over 8kRPM may be the issue. Unless owners are OK with rebuilding every 100h or so. :)

    Actually, last year's Cup had 50 hour interval and RSR was 40 hours.

    That's true, but most of the failures have occurred in the valvetrain which is independent of the pistons/stroke issue.

    Yep, no problems at all. Porsche has handled this perfect so far. Only trouble right now is that the new engine was delivered last night, but something went wrong when unloading it. So this morning, when the mecanics came in, they found my new engine up side down ! angel So now that one is on its way back and Porsche will deliver a new new engine😂😎 But this is NOTHING to blame Porsche for, but rather the drunk (???) lorry driver...

    Only thing I now need to do is to make sure to have sufficient insurance. If the new engine, god forbid, blows, it will be on me, since you don't get another two years on the new engine.....

    But thanks to Porsche taking good care of me and my problems, I will be on track as usual in April smileykiss

     

     

    Suggestion: Why don't you get a warranty extension?

    Also, another suggestion: Be careful with the information you provide here. Porsche is monitoring this forum and since track racing isn't really covered by the Porsche warranty...I think you get my point. Smiley They may be nice once but maybe not the second time.

    Re: GT3 engine issues again?

    That is the connecting rod?  (See picture). No way. It looks similar but way too small. The end connecting to the crank would need to be much larger. Strange part. Certainly an end cap paying there but you can see it does not attach to what is shown as the rod. 

    This is not good news for GT3 owners hoping to resell or hang on to for decades. 


    Re: GT3 engine issues again?

    I was puzzled for a while, too.. Then realised it was the big end cap viewed end-on.

    Re: GT3 engine issues again?

    RC, seriously? If something breaks with a GT model on a track the warranty is void?  That can't be.

    It is in the discretion of your dealer and regional manager (except for Model Year 2014 GT3 that came with explicit track warranty).  So far, all reasonable claims from track failures have been covered by Porsche.  Stopping track coverage would be a major policy change, but it is within Porsche's legal rights to do so.  I'd be very surprised to see this happen though - several competing manufacturers have recently made specific track warranty coverage part of their marketing efforts and Porsche's reversal would have a significant cost (damage to their brand image would likely exceed their warranty expense savings by a wide margin).

    Re: GT3 engine issues again?

    So guys, got the car back last week with new engine. New the first 1500km is done. No extensive reving first 3000km, so half way back to that glorious sound between 8-9 thousand and open windows in all tunnelssmiley

    But a really terrible trip from Stockholm to Oslo (and to Rudskogem raceway in Rakkestad) and back onCup2's, sub zero degrees and snowfall two out of three days....laughlaugh. But the company was very nice, thank god, so no need to freeze during the nights....frown

    Need to have the engine run in by end of April for the first real track day of the season. So far the engine seems fine, drank some oil, but nothing extreme. Extended warranty and all fine with Porsche. But that might not be such a big surprise? During the winter I have thought about what could have happened if the enegine would have blown in eau rouge in stead of in the slowest chicane on Spa? Huh.....heart And maybe Porsche thought about this as well?

    Well, all fine and good with Porsche regarding the GT3, just the Panamera problem left to solvekiss 

    And Porker, i would love to join you guys for a track day. I wouldn't have any problems with looking in to the "ass" off bluelines white, lightning fast GT4 

    I don't have a lot of experience of the internet "weirdos", but I actually met a guy that on the internet seemed almost from out of space, but actually was a very nice and funny guy, that I really enjoyed spending some days wiith.But I guess RC has his points as well, regarding guys pretending being something different than in real life. This guy was not so good looking in real life as on internet, but I'm sure you are working on that issue Whoopsy.....wink

    Thanks PorkerSmiley 

    Back to Spa in October (I hopeSmiley), so be readySmiley Right now the snow is poring down and I'm struggling to get enough km in to the new engine before the first track event next week. Snow and Cup2's is not a perfect match, but what the h.., some drifting practice might be fun....👍😎

    And for all of you that wonders, the lift is crucial when the snow is more than 10 cm high on the streets....Smiley


    Re: GT3 engine issues again?

    So, the new engine works ok, but one thing is annoying. After running it in for about 3.000km (no need really, but did it anyway since the spring been awful up herelaugh), I've now started to USE the car again. Quit a busy schedule with in total 10 track days (Sweden,Norway and Estonia) the last 3 1/2 weeks and a total of about 2900 km on track and the car devours oilheart 4,5 l during the track driving run. PAG says it's all fine and nothing can be said until the engine has run for about 10.000 km.....mail

    So Porker, be ready to bail me out from some dubious workshop when I visit Spa in October (but this year I will ship the GT3 and take the Panamera or fly down)

    But otherwise it's great that the season finally is here. Also flow down to Germany for two days with the cup car on Hockenheim. Great fun (Whoopsy,this years was really on the next level compared to Leipzig last yearblush. I do hope the Mexican wedding was worth your missing out ?!  ) and a good thing to do after starting to think of myself as a quit decent driver, building confidence on the track days. Both Timo Bernhard and Wolf Henzler where there and drove as well and boy, I'm such an amateur.....smiley I'm not the most humble guy generally, but you will NEVER see me brag about my driving skill on this forum. I am lightyears after the REALLY skilled guysyes But I'm having FUN👍✌️😎And boy what a great track. Nice feeling to be able to rev out the cup car in the parabolica....😛

    Next up some relaxing days in Palma, then back on track againsmiley

     


    Re: GT3 engine issues again?

    Sounds like you're having fun!  Some of the GT3 guys have reported less oil useage after more time (but your consumption seems pretty high)

    Is it possible that Porsche "re-adjusted" lubrication for the 991.1 GT3 engine? Smiley Smiley 

    1.5 l oil / 1000 km is a tiny bit much for late generation Porsche engines...

    Re: GT3 engine issues again?

    I refilled just last week 0.2 Liter and have just passed 10k km.......- None of my porsche's consumes oil as described....but then I must say I am not tracking them. (just spirited driving last week at the mille miglia indecision)


    Re: GT3 engine issues again?

    Well my 911R ate 0.5L of oil already for 4000km................

    My Cayenne Turbo S ate a whole litre at 9000km. It's now at close to 11,000km
