Porsche 911 (997) GT3-RS

gwyllion · 21 Jun 2006, 20:06 (Ref:1638606)

According to motorsportaktuell 2 Porsche 997 GT3-RS will debut in the 24 hours of Spa. The pilots will be Maassen, Luhr, Bernhard, Dumas, Tiemann and Lamy.

The road car looks fantastic: http://www.porsche.com/all/911gt3rs/en/page1.htm

Will the 997 have a 3.8 liter boxer or 3.6 like the road car?

Motorsport akktuell writes that the car will have a 3.8l engine and should run with 1225kg.

What Motorsport aktuell forgot to explain are the following:
- the 997 GT3-RS road car will be on the market from october
- the 997 GT3-RSR race car is not homologated
- the sporting regulations if the GT2 did not allow works entries
- why would race Tiemann and "Prodrive works driver" Lamy and not Lieb, Rockenfeller, etc.?

Sometimes Motorsport aktuell has rumours not news

Because Mike Rockenfeller will be on Grand-Am duty at Barber Motorsports Park that weekend. And Marc Lieb is cutting back his schedule due to his studies at the University....

Marcel Tiemann is a regular driver for Manthey anyways..

gwyllion · 21 Jun 2006, 22:31 (Ref:1638701)

BTW the engine of Manthey GT3 MR, that won 24 hours of Nurburgring, is developed by race division of Porsche. The drivers (Luhr, Bernhard, Rockenfeller, Tiemann) strangely are on the list of motorsportaktuell.

Looks a little bit like another MC12 for me. First race car development and after that the street car. Maybe there is realy a problem with GT car regulations because some major points of the car must be the same on road and race car and only if road car is developed for maximum race car performance you are able to win races.

**Adam43** · 24 Jun 2006, 08:54 (Ref:1640196)

Another MC12. Surely it is not that extreme. There is already a road car it is based on (has been for quite a few years!). This is just a version of that road car. It is no worse than the Panoz.

I don't see a problem here, especially as Porsche will prbably sell quite a few of them. As they do with the GT3s.

ger80 · 24 Jun 2006, 10:40 (Ref:1640231)

Ok, of course not so extreme like the MC12 but the same game. But where is the sence? Others like privatier teams who want to race with a nissan 350z, tvr, or what else are not able to play this game. So why we have a set of regulations that allows to build a fast car only with playing this game? I always thought that we want many different cars

JAG · 24 Jun 2006, 13:13 (Ref:1640272)

If it races at Spa it will be in one of the invitation classes, like the TVR, Mosler etc.

If it's coming in at 1225kg, it's more likely to be a Cup car, seeing as GT2 minimum weight is 1125kg, or so penalised it will not be competitive.

ger80 · 24 Jun 2006, 18:29 (Ref:1640430)

Thats not the point for me, they started the race car development much earlier than the start of the road car production of the GT3-RS. Next time they use the LMP2 car and put a 911 chassis on it and sell a few ones and get the homoligation ???

JAG · 24 Jun 2006, 20:24 (Ref:1640485)

The 997 GT3-RS/RSR is simply a stripped down 997 Carrera, or whatever the base model 911 is.

Start to worry when the GT2 car is based on a model unrelated to regular 911's.

**Adam43** · 25 Jun 2006, 11:54 (Ref:1640793)

Quite. I think we are looking for outrage.

All the GT racers are modified in similar ways. In addition it suits Porsche to have it described as a car built for racing - it'll use that as a marketing point. Of course how it is described is unimportant. It is how it fits to the regulations and also what class of regulations it is conforming too.

It's great, isn't controversial in reality (IMHO) and does, as gwyllion says, looks fanastic. I want one and I want to see one race.

TheNewBob · 25 Jun 2006, 23:33 (Ref:1641200)

In one way or another it's basically the next update in line from the 996 GT3-RSR - where's the problem in that?

The car, along with the Ferrari 430, is likely to be making up the majority of the GT2 class in the coming years, so might as well get used to the thing!

That´s not true. Manthey test the "normal" 3.8l RSR engine but decided for the race to use their self developed 3.9l engine.

It is interesting. Because currently there is no road car of the 997GT3-RSR (the road car would be presented on october, 1st and it would be called 997 GT3-RS).
But in the G2 class we have rule change that now "the car must be raced in a national series in the past three years" and not "in three national races" like the rules are in the BMW M3GTR.
At the moment their is the possibility for two Belcar races and one Langstreckenmeisterschaft race before Spa. But both series have changes their regulations that the cars must have a road car or be homologated for the ACO and FIA classes.
So it would be very interesting to see how Porsche gets the entry (if Porsche gets a special way i´m not happy but happy to see the car

)

gwyllion · 4 Jul 2006, 14:06 (Ref:1648041)

More information from someone within Manthey:

2 cars will participate in 24 hours of Spa
drivers are confirmed to be Lucas Luhr, Marcel Tiemann, Timo Bernhard, Romain Dumas, Sascha Maassen and Pedro Lamy
tomorrow the car will test at the 24 hours of Spa testday with Lucas Luhr and Marcel Tiemann behind the wheel
the 3.8 liter engine currently produces 485 hp at 8500 rpm and 435 Nm
at the moment they are using current sequential 6 speed gearbox, but a new one is being developed to increased reliability; Alzen for instance did not dare to use the sequential box during 24 hours of Nurburgring this year
the rear wing will be 50 mm wider at both sides

panoz.lmp1 · 4 Jul 2006, 14:13 (Ref:1648049)

There is an official Porsche press release for this (german version: http://www.projectlemans.de/content/view/2144/53/). But they forget to explain why the car can run at Spa ;-)

Because the press release said that the car is based on the 997 GT3 RS. And there is another press release which announced the official presentation of the 996 GT3 RS road car for October, 1st.

So tomorrow will be a very intersting day ...

The guy from Manthey said there was a press release, but I could not find it. Thanks for this pointer.

According to the press release, the new RSR races with a higher minimum weight (1225 kg instead of 1125 kg) to use wider tyres: 14" instead of 12".

Bramzel · 4 Jul 2006, 21:29 (Ref:1648372)

And the first pictures:

http://www.endurance-fans.de/galleri...2_itemId=20278

I must say I'm dissapointed, and I hope that there will be some changes, as I find the looks of the car a bit... amateuristic. The way the fenders are extended, etc, the average Nordschleife-Porsche looks more professional. I know that it's only looks, it'll be fast of course and professional as hell. But I'm someone who finds the looks of the cars rather important as well, and in that aspect I find this a large dissapointment after the 996 RSR wich I find rather sexy.

JAG · 4 Jul 2006, 21:56 (Ref:1648425)

That looks fantastic, look how wide it is, look at those exhausts!

The wheel arch extensions are fitted the same way as the 996, with some kind of rivet arrangement.

Why the 14in tyres, better for ALMS circuits?

Wonder if this will help teams, maybe even Porsche, to produce a turbocharged GT1 version, seeing as the same suspension layout can be used.

arakis · 5 Jul 2006, 11:27 (Ref:1648786)

what do u guys think can the 2'' larger tyres realy help more, then the 125kg extra reduces from performance. My opinion its going to strugle on accel and top speed, and bracking high speed corrners also. but it will have a huge advantige in the slow corner like the almost 270 degre one at spa.

gwyllion · 5 Jul 2006, 11:36 (Ref:1648798)

Because of the higher weight they are also allowed to use bigger restrictors and thus have more power. According to endurance-info.com the aero has improved and is 7% more efficient. So I guess top speed should be fine. The chassis is said to be 10% more stiff as well. I am convienced that Porsche Motorsport has tought this through.

gwyllion · 5 Jul 2006, 11:54 (Ref:1648815)

In the morning session the 997 GT3-RSR did 2:26.932, compared to 2:24.366 by the Ebimotor 996. This looks very promising because they are not working on fine tuning the setup yet, I assume.

According to the provisional entry list the 997 GT3-RSR will race in G2: http://www.proximus24hours.com/pictu...list_03-07.pdf

According to this list Marc Lieb will race instead of Romain Dumas who will be in the Ebimotor 996 GT3-RSR.

gwyllion · 5 Jul 2006, 16:22 (Ref:1648985)

During the afternoon session the 997 set the fastest time of GT2: 2:23.940 compared to 2:24.245 of the fastest Ferrari 430.

As you can expect from Porsche Motorsport, the new car is fast out of the box
