It's a device that will allows me to have the exhaust flaps fully open.
The OEM controller, even if the Sport Exhaust button is pushed, only opens the valves fully between 0 - 2500 RPM and 5500 - 8000 RPM (approx). This device plugs in the oem plug and has 2 buttons: Exhaust Valves fully open or Exhaust Valves controlled by the OEM controller.

Cool stuff. Speaking of that, do you have noise regulations on the tracks where you go to?

Yes, 130 dB(A)

I managed to create the valve controller mount... I started off with a 1m long 25mm wide and 2mm thick piece of Alumium:



Then I bent it:





I went with two pieces even if the first one I think is sufficient because I want to make sure I don't lose the controller in the engine compartment.
Here is the end result (I also used some textile tape to be a complete overkill
:)
):





I can't wait to actually install the controller!

Just returned from my Nurburgring tip and, what a trip it was...
There are many things I want to share and I intend to cover the following:
1. the trip to Nurburgring and the first day
2. the second day at Nurburgring and the road back
3. Manthey visit and first mods

So, without further ado, here it goes :)...
From my place to Nurburgring it's about 1650km (~1009 miles). I'm not as young (and maybe reckless) as I used to be (when I could do this in one day) so it takes me 2 days to get there.
There were no problems getting to Nurburgring but I have to say the car got much more attention than I thought... Firstly, the Border Control (Romanians and Hungarians) congratulated me on the car, asked me rev it up and to do a launch control :)). So, when entering Hungary I did my first launch control.
Then, when driving through Austria, in a 80km/h zone, I was doing 87km/h and a gentlemen in a gorgeous C2 Convertible Corvette



passed me (I think he was going 90-95km/h). He gave me the thumbs up when passing. And I also got a number of thumbs up by other people or other Border Control officers congratulating me on the car. This is truly something I did not expect...

Anyway, I got to Nurbugring and I was welcomed by "great" weather. The forecast also didn't look to good - rain for the following 2 days.
Oh, I forgot I did not tell you what I was supposed to do at Nurburgring... I attended a Porsche Track Experience event - Master Level.
As it always happen with the weather forecast, as it is not 100% accurate, you always hope the weather will turn for the better. But, the following day I woke up to a rainy Nurburgring just like predicted. It stopped raining around breakfast but I knew the track wouldn't dry fast.



I had the obligatory briefing where I found out I won a 1 hour of personal coaching with Mathieu Jaminet - due to happen from 10:30 AM the same day.



I was happy to win that but sad I would waist the hour driving a wet track. Anyway... I did my first 3 warm-up laps in ever improving conditions with my group (consisting of 1x992 Turbo S instructor car, 1x718 GT4 instructor car, 2x992 GT3 rentals, 1x718 GT4 rental, 1x992 TurboS rental, 1x991.2 GT3 and 1xFerrari 488 Pista) and by the time I was supposed to start the coaching most of the track was dry.







I had Mathieu for 3 laps where I leaned the wet lines (first lap) and I used the dry lines at an increasing pace for the following 2 laps.
During the last of these 2 laps I managed to go below 8min (7:55) BTG with almost a standing start. Here is the lap:


This is the first time sub 8 on Nurburgring and I have to say I was most proud of the feat.
As you can see, I am coasting in a number of fast parts of the track - so I can be even a little bit faster. Especially on acceleration Mathieu would leave me far behind (Turbo S vs GT4) and then he would go a little bit slower to allow me to catch-up. In some cases (like the coasting areas) that was a bit to slow, but that is a totally understandable approach from Mathieu.
All in all, it was a very useful session where I mostly learned the kerbs I can ride.

After this coaching session it started raining and the track changed to full wet once more - so nothing else to share during this day.

And now, about the second day... Well it all started not in the best of ways. There was a lot of rain and the track was closed to avoid aquaplaning (apparently there were a lot of rivers crossing the circuit).
About 2 hours later the track opened but it was full wet... Fortunately it started drying and by 1PM the track was completely dry. This allowed me to have some fast laps.





Here is my best lap (7:49.41 BTG) - with an almost standing start.


I have a good pace but there still are some areas of improvement - but this is for next year.
Any advice on technique, lines, etc is welcomed!

There is one more video I want to post - with an instructor (Chezito) following me but that requires more editing and will come later.

Oh, and one more thing about the car - I really love the Miami Blue color... It really stands out in front of all the white/grey/black cars.



And, even if Gentian Blue is a great color and I especially like the bronze wheels on that, I am especially glad I didn't go for that (I basically had to chose between these 2). About 10 rental and instructor cars were 718 GT4's and 9 of them were Gentian Blue with gold wheels. The other one was Guards Red, also with gold wheels. Another thing to mention is the interesting spec these cars had (all were the same): Clubsport Package, PDK, Steel Brakes (I guess you would expect this) but also Manual AC, Leather Package (on the dashboard), PDLS...

How did the tires hold up after your alignment change?

And, before I move on the the Manthey Racing visit (& mods), one more video I want to share...
During the last day, the instructors were allowed to follow you so I took the opportunity to ask Chezito Mendez to film me (he's driving the 992 TurboS below)




As you can see, it is not quite the cleanest of laps, but the rhythm is decent and it's a 7:55 BTG lap.
Chezito made a mistake at 7:20 and couldn't make up the 2 sec lost until the end.
As the sound is coming from the TurboS, you can definitely hear him coasting a lot... 650PS vs 420PS
Cheers!

Next up, the Manthey Racing visit...

As usual, not a lot to see in the parking lot:



Anyway... at Manthey I've done a number of things:

1. OEM suspension kit which consists of:
Top mounts from a 991.2 GT3 RS and some MR spacers for these mounts





Shims 10mm a side for the rear and 2 or 3 mm a side for the front. So, I effectively increased the width by 4-6mm in the front and 20mm in the back... As you can see the OEM shims are still in place







Rear toe links - because of the additional width, the OEM toe links restrict the toe setting. As such, new ones are needed. I have no idea what car these come from, they only have Germany and a 4 digit code engraved.







Because of the increased width, TUV mandates the mounting of these pieces (basically in Germany, the wheel can't extend more than the bodywork). These are VW MK7 Golf pieces. I have not mounted them yet...





As a result, here is the alignment:



2. The Brake Upgrade consisting of:
Pagid developed pads





Steel brake lines





And obviously some more racing brake fluid (Endless).
I've also done an oil change - I was at 6.500 km ~ 4.000 miles



I've done all of this after the trackday, so I am very eager to try the new setup - TOMORROW :)
Stay tuned :)!

Hello,
Thanks for sharing yr experience with the GT4.
Question:
As you do so many trackdays with this (expensive) car, do you have track insurance ?
Regards

And one last thing about this years Nurburgring experience: the trip back.
I was in a hurry after the MR visit and, since I was in Germany on a de-restricted Autobahn, I managed to reach 302km/h (~188mph) just before reaching a dangerous bend :)...



It was something I wanted to tick (getting to the 300+ kph club), but I don't intend to reach those speeds any time soon. I think the track is much more fun and engaging and you don't depend so much on what other people do.

One interesting thing where I need some thought is regarding oil consumption... Let me explain:
  • first 3000 km (~1865 miles) - ZERO oil consumption
  • 2 trackdays + the trip there, 1000 km (~620 miles) - ZERO oil consumption
  • trip to Nurburgring, 1650 km (~1000 miles) - 0.5 liters (0.5 US quarts) of oil consumption
  • Nurburgring track action, 700km (~630 miles) - ZERO oil consumption
  • trip back from Nurburgring 1650 km (~1000 miles) - ZERO oil consumption

Any ideas why this is happening?
Thanks!

I was planning of showing other pictures from this trip but apparently there is a software bug that is preventing me from viewing and downloading the files - Porsche says it is being looked at as we speak but there is no telling on when it will be fixed.
So, I will share the pictures at another time.

Until then, the story goes on...
After returning from Nurburgring, I got to install the Cargraphic valve controller. It is quite easy to have access to the engine (especially if you've done it before) and connecting the valve controller is not super easy but not difficult either (I did not remove any parts to connect the valve controller).





Of course, the operation would have been easier if I wouldn't have dropped a washer in the engine bay... I had almost all the tools to retrieve it (telescopic mirror, magnets, etc) but I couldn't find it. I ordered a endoscope and only this way I found it (after 4 hours of looking :) ).



Here is the end result:



I also found a great place to put the remote control for the controller - removed the armrest ashtray and the remote control fits perfectly:





Sound wise, it is a great improvement as the OEM controller would keep the exhaust valves closed in the mid-range (below 3800 RPM) no matter if the PSE button was ON or OFF. This mode is only visible on public roads as on track the car is always above 4000 RPM so the valves are always open.
But, the car still doesn't sound as good as the 981 Cayman I previously had. I think I will buy an aftermarket exhaust at some point, but I don't plan to do so in the next 2 years.

Hello,
1/ About track insurance.
Reading you have insurance on the track. What company you have? Is this for track only or included in your road insurance ? Cannot find here in Belgium. Only insurance for 1 trackday is possible, but this is 500euro/day…
2/ Thanks for sharing these pictures from the engine. It does not look as good as a Ferrari engine I am afraid :)
3/ The sound is not as good as yr 981.
I guess this is due to the particle filters in the exhaust ?
The GT3 also a 4.0 does sound good, what is reason ?
When you consider another exhaust, do you also remove the particle filters ?
Regards

1. In Romania we have different insurance - and I am fully covered unless competing in events.
3. Yes, the particle filters are not good for sound. But no, I don't plan to remove the particle filters because that requires an engine remap (something I don't want to do). I want to replace the rear part of the exhaust. But, again, not in the next 1-2 years.
I can't tell anything about the GT3 sound because I haven't driven one.
