"NO RWS, due to racing homologation"

eh, say what now? For which racing series would this homologation be then?

Nizer

Isn't the Ruf V8 something like 88lbs lighter than the RS 3.8 lump?

RWS probably makes the absolute limits of the car higher for everyone, and probably drops significant time in the process. I'm certain an updated Lion will be available soon as retrofit.

The question in my mind is more one of driver experience. The 911 has been around for 50 years not because it's easy to drive, but because it's challenging and involving. With RWS the 911 sounds like it drives more and more like a more powerful Cayman and less and less like a 911. Question is, is that a good thing or not? I'm not sure, but I haven't driven one, let alone lived with one. The 911 used to be one of those cars that grows on you, backwards and confusing at first, but better and better the more you stuck with it. Does making it handle like a mid-engined car lose some of that magic? Sure, it's faster, but is that really the ultimate goal?

so will the 4.0L be the metzger engine?

^^No.

Not sure but I figure the Porsche flat 8 or V8 would be heavier..

Good point, but It could be that the RWS delete kit will also be available if it proves too hard to set up or change setup, making it slower due to improper setup and give it the heavy trail brake fun back.. Than again, I have not driven a 500HP Cayman yet so that might be fun and faster as well.

No.

Metzker was the best engine, this is sad

I believe the Ruf V8 weighs ~200kg, but not sure what is included in the weight. (source - http://www.carthrottle.com/porsche-911-ruf-rgt8-v8/).

I remember reading (probably somewhere here) the Mezger in 997.1GT3 weighs - 258kg ((fully dressed weights + DM flywheel).

The V8 in 918 apprently weighs a remarkable 140kg (source - http://www.edmunds.com/car-reviews/features/2014-porsche-918-spyder-hybrid-ride-along.html).

This is exactly what I have been thinking as well.

1) that would be a confidence loss in RWS - not to put it in the RS
2) If the reason is "racing homolagtion", then the RS would also not be allowed to have e-steering, e-handbrake..if that would be the case, I´m fine with that and might even consider this car..

Would be for both FIA and ACO. Both organizations are trying to align their rules for 2016. It's the primary reason that we have not seen development on a new motorsport engine for the 911. The current 911 RSR is based on the 911 4s. All wheel drive is illegal in ACO regulations and so will RWS. It would not preclude the new RS from having it - Porsche AG just wont race with it. The interesting question is do you bring out the RS with a similar engine as the new GT3 or do you wait and bring out once the new rules are in place with a new engine. The current 991RSR is allowed one EVO update - but it has to be within the season. More than likely we will see an update at WEC Bahrain event.

P_collector

yes..but all that doesnt answer the question, if RWS isnt allowed, then the RS shouldnt be allowed with PTV, e-brake, e-steering, e-diff, and so on, either beacuse I dont think these will be allowed by 2016 in the RSR. Never.

brake dust

All wheel drive is not allowed either but yet the 991 c4 is what was used for homologation for the 991 rsr. Homologation Is based on approved chassis and engine. ACO rules also have a technical set of rules in which all wheel drive and RWS do not comply.

Few hours ago saw a white 991 that looked like something between Turbo and GT3 - GT3 front and big wing but air inlets at the rear. Sounds like something that might be GT3 RS, or just a modded Turbo... It was parked by the Ferry Building in SF. Weird. I have no idea what it was. Maybe someone knows more?

I beg of you, tell us your not the only person in the Bay Area w/o a cameraphone and took a pic.

Sorry, was using binoculars from an office building window right next to it, so camera phone did not work out.
