997.2 GT3 at Geneva
Just a 3.8 build... Like some of the stuff and not so much on the other....

That is interesting to see Porsche use DFI for the Carreras but not for the GT3s. What's the explanation for that?

here they continued on the GT1 base.
And it sounds better than a DFI block

I'd imagine it will be much easier with the FI engine (Turbo, GT2) as they are not stressed nearly as much as the flat 6 in the GT3 which is already stretched to the max with the GT1 block. If you make the engine less beefy, could result in more problems. Making more than this 430 hp that meets emissions and has the same durability as the GT1 is going to be tough even for the Porsche engineers.
I fully expect to see a GT1 based 4.0 liter in the GT3 prior to DFI. The logical step would be for it to follow the cup cars which I was surprised to know still don't have DFI. Just a 4.0 liter flat 6.

Yeah, I meant the RSR's. The RSR's went in that same progression and everything makes it's way down to the cup cars and then to the street GT3's. Naturally it would be better tested in racing first.
And yes those motors are rebuild a lot, but so were the 3.6's and 3.8's that came before the 4.0. Those motors rev that high for long periods of time and are subject to far more stress than a street motor. But the technology is the same.

Maybe, I'm thinking 475-500 which is under rated. I wish they'd go ahead and do it. Sports cars are a dying breed, we may not have the GT3 long enough with these small 15 and 20 hp bumps to get to 500.

HeavyChevy...you forgot...The 997 RS also has a re-calibrated PASM (stiffer) to operate with the WIDER rear axle, but also a pair of split lower control arms at the back...for better handling.
The RS body shell is also 10% stiffer than the GT3...which is far stiffer than the MK1 GT3/RS.
And, some RS's came from the factory with welded roll bar plates.
I am fortunate to have have both the MK1 and a 997 RS...no comparison...the RS is a keeper.
and, please don't make the connotation of the "$175k bling buyer" of all RS's.

Sounds like a bunch of fluff to me and still is nothing near the changes that went into the 996 RS from that GT3 model.
What is there no comparison in? The RS looks better, but what else can it really do better? The 996 RS was definitively meant for the track. PERIOD. The 997 RS is a GT3 with little tweaks and lots of bling. The 996 was little bling and lots of tweaks.
