i want to drive one now
thanks McLaren! (Y)
Porsche 997 GT3 RSR #2
great pics, anybody knows why the two exhaust are placed in that way, could it create a venturi effect?
a very impressive race car!! with looks better than the previous models.
I've read somewhere that it has a 3.8-litre engine. Why does the road car has a 3.6-litre engine then?
What is up with all the 3 letters and 3 number titles?

3.8 has been around since the 996 GT3 RSR, FIA/ACO gave it a different restrictor rule for it....I guess they just went with a bigger engine all around on the new car....
The road car's block is still shared with the racer, unlike the not GT3 variant of the 997(the 3.8 in the S model is not based on the same design)...

Thanks for the info. Could it be that the block is the same since the 993 (at least), which had a 3.8-litre (3746cc) Carrera RS road going version? The bore and stroke of the 3.6-litre versions (only the GT variants since the introduction of the 996) are the same, I think.
The blocks for 996 GT2/GT3/Turbo and now the 997 GT3 were all based on the same split-case dry sumped design that originated from the 911 GT1 program......which means they have their root in Porsche's racing program. While the production version may share the displacement of the "special" model, the basic design were different...I assume the block casting has been change from 993 since the GT1 model, and all subsequent 911 were watercooled, which means cooling channel and so forth has to be built in....

That's how Porsche/Audi/VW do it, complaints should be directed to Ferdinand Peich.
:D I dunno really...nostalgia?
the 993 engines were the last air cooled porsches , from then onwards all engines are liquid cooled (and obviously this meant a new design altogether!)
BTW this car is having its debut this weekend with 2 entries in the "G2" class for the Spa 24 hours...

But still despite changing the cooling system the block could still be the same (conveniently adapted), or am I very wrong? Because not only share the displacement but also the bore and stroke (100 x 76,4 mm).
