I love them, way out of my league though.
From what I've been told, if sustained full bore use is what you have planned be aware that they use a water spray for cooling and you need to keep the reservoir topped up. The engine will also cut power if it gets too hot which is very easy to do, even with the spray working. The water spray is a sticking plaster fix for an issue found late in the day.
It would be good to know if the above is true from someone more knowledgeable than I

I watched this on Sunday. These Apex guys (Robert and Misha) are making the best NO BS car content on YT at the moment. Such a good video.
Real insights into how seriously MR take research and proving out their offerings and products.
You can have ultimate confidence in them.
GT2 RS is a serious piece of equipment.
For those that are interested here is also a great breakdown of the GT2 RS Clubsport vs the GT2 RS road car and GT3 Cup.

Engine will derate once the water tank runs dry but you can get an expansion tank for the road car which increases capacity to the point where you won’t run out of water before you run out of fuel.

Also interesting that Porsche didn’t think that this was such a issue that they change cooling or turbos in the new 935 or the GT2 RS Clubsport. They just relocated the tank and made it larger.

Cheers, Porsche must be happy enough with the performance of the cooler then or decided it wasn't worth any more investment?Also interesting that Porsche didn’t think that this was such a issue that they change cooling or turbos in the new 935 or the GT2 RS Clubsport.

You have to think about what the car is built for...and then there’ll have been a bunch of trade offs to factor for.... how many other 700hp road cars can lap circuits lap after lap after lap with just regular ol’ 98Ron and 5L of distilled water( standard tank), and has pretty much no technical overhead for your ‘typical GT car driver’ lol, to think about. And then there is cost.
Most of the other cars at this peak performance level are highly specialised, cost twice as much, or are fragile as glass.
On most trackdays people aren’t doing long stints, maybe 10 or 15mins and then back to rest themselves and the car.
In extreme temps and extended acceleration loads, those IATs are going to be really pushed and the water cooling serves as a first line of defence, with ECU knocking power back as a last resort.
Another approach to the cooling side of things is to stop temps getting so high in the first place, and so aftermarket solutions exist for more efficient intercoolers as well. CSF/PWR.
The OEM IC core are already very effective and so CSR/PWR make use of an effectively F1-grade core, and billet tig-welded end tanks. But this is all cost... Porsche built the standard car for a typical situation, there’s always a bit of room for improvement or sharpening for a particular application.
I owned the 991.2 GT2 RS for two years and this has become my favorite GT ever. I had to let go my 3RS recently a bit reluctantly but also with the hope the forthcoming GT3 and GT3 RS could could be in my garage with a full N/A play still to enjoy. But at some stage I asked myself: keep 2RS or 3RS. The former won easily and... I am a 3RS and N/A fan.
Pros:
- it feels special. I know some say it doesn’t have a race heritage engine but... Porsche showed case what they could do and some videos actually show all the motorsport which came into the design.
- it is a beast, it is speed! You have to drive it to understand what an amazing experience it is! And the more time you spend with it... the more special it feels, the bigger the bound. The stepped delivery is analog. You feel it more than in a modern Ferrari or McLaren. There is emotion in this car as far as I am concerned
- this car requires respect. Electronics keep you on track but... it let’s you know you have to respect the car it is. You know you have to warm up the tyres! The throttle requires some feel and subtlety. By the way, the brakes are the best setup I have experienced on a GT Porsche, the standard of which are quite high. And at the speed you can reach, being confident in the brakes is key. Feel brake in my car is right up there with the best
- it’s torque makes it a decent cruiser if you decide to drive the car to a track using motorways or take kids for a drive...
- ... and yet it has mechanical noises in abundance to put the “GT noises smile” on your face
- they are mega reliable which, for a sport car the performance of which is closed to supercar is brilliant
- they look so gorgeous and the carbon bits make it special. I can’t help taking pics of this car. My son has it as his iPhone and computer screen savers!
- the exhaust note is great and because it is pre OPF, you don’t have a rev limiter at idle, it does hilarious pops pops when shifting down gears or releasing the throttle (especially in the 4,000 RPM)
- the more I drive it, the more I appreciate its amazing handling, breaking, grip. It is not as easy to begin with, as a 3 RS and feels heavier... but when you begin to put it together, I find it so much rewarding.
- like most Porsche and even more so GT cars, once sat in it, you gel with the car. And because this one is more difficult to be tamed, this “I am one with the car” feeling is even more important
Cons:
- more difficult to drive and feels a bit less naturally balanced/ easy than a 3RS... to begin with. But this is the average driver commenting here. And with time, I find this is what contributes to making this car feels so special, entertaining
- yes... it doesn’t rev to 9,000 RPM and it doesn’t have the high pitch of a N/A GT3 or 3RS. But... I was not a fan of turbos and with this one... I love them. There is this whistle when you accelerated which is addictive
Listen. I love this car. I couldn’t believe it when I had an allocation. I can’t believe it has been almost three years I took delivery. But each day I like my GT2 RS more. I think this is a keeper and a car which will be remembered.

Thanks for replies gents.
Looked at this one recently and glad to say it will be on my drive tomorrow.
Congratulations. Looked at this one recently and glad to say it will be on my drive tomorrow.
A little late but I can only say from my experience the 2RS is indeed a stunning car, as another owner has said above. As someone who has owned each generation of GT3, I hadn't expected to enjoy the 2RS as much as I have. I did own a 997GT2 for a couple of years, but never loved it more than its GT3 counterpart. But with the 991, it is the other way around - the 2RS's combination of brutal power delivery and a sensational chassis is hard to match. It demands a lot of the driver, but rewards in equal measure.
In the summer I chose to fit the suspension and brake upgrades from Manthey Racing (not the aerokit as I felt that was pretty expensive for a gain that only the best drivers would feel), and that has taken the car to another level again - both on track of course but also on the road. I took the plunge after sitting in with Tim from Apex in their GT2RSMR taxi - it was a stunning lap!
There are a few comments on the water tank. Even on the hottest day in the summer at the Nurburgring, it only needed filling up once during the day, so I have not bothered to fit Manthey's extended water tank.
Enjoy in good health!
Had the car 8 days now and still haven’t driven it !!! I know, I know there’s just to much salt on the roads and I’m aware I need to get heat into the tyres before pushing on and at the moment/time of year it’s not ideal conditions. Forecast for the weekend here is dry albeit cold so may venture out for some provisions and see how it goes.
