Sebring, a .2RS on DOT R and LSD tires can lay down a 2:17.
The 9974.0RS can do a little better with the same tires and LSD.
Mid to high teens.
997.2CUP is able to do 2:05.
997.1CUP is slightly behind the .2CUP.
996 Cup is slightly behind 997.1 Cup and typically seen in the low to mid teens where the 997.2RS and 4.0L roam with DOT tires. Given slicks it would be same.
991RS on Sport Cups will be in the low to mid teens which is 996 Territory.
Given slicks the 991RS is right there with the 997.1Cup....
Now this is flat and level 17 turn sebring of course, and in a sprint race obviously the weight of the street car will take a toll on it..
But data is interesting none the less.

Pete,
I think everyone here agrees and knows you've hit the bulls-eye with respect to, at least, the GT cars from Porsche.
And I'd imagine even the gang at the GT division in Porsche agree with you, but given the combination of government regulations and our legal system, it is simply is not feasible to build a Carrera GT 2.0.

I don't see 997 values slipping, suggesting in some ways that the market sees a high point, and that we're already on a down-slope towards 4wd electric self-driving bubbles. I'll keep looking for throwbacks (BMW 1M, 4.0, etc) left in the wake of this charge towards "progress" to pick up... as long as they make them.

No. By this logic the ultimate track car is 4wd, because it's faster. It's mid-engine, because it's faster. The GT3 RS nowhere close to best, because it's not fastest. The GT-R is faster. The 918, ZR-1, Z06, Viper ACR, the list goes on... I don't want a GT car because it's fastest. If I did I'd buy something else. I want it because it's a balance of performance and feeling, of innovation and tradition. And I want it because it's involving and demanding. Did the Carrera GT scare Porsche more than it scared customers? I see the current generation of Porsche supercars is an over-reaction, a mandate from its overlords that Porsches will be easy to drive. And I think this is a mistake- it's not what Porsche is. Challenge is part of Porsche's identity. Speed is a given today, and you just need to look at Tesla's 3.0 second to 60 four door sedan to realize that next generation cars will be blindingly quick. For most faster + easier = progress, but that's not everyone. Some want the challenge. I'll try the GT4- I think it's a step in the right direction. But it's still watered down skim milk compared to what it could be, as is the new 3RS. I'm still waiting for the best bits of both cars (in either platform) for the full-fat experience. He're hoping the overlords will still allow this to happen.

Has anyone got the actual bore & stroke dimensions for the 4.0 vs 3.8 liter GT3 motor to know where the additional 200cc comes from? Is the CR the same, or were changes also made to the head to keep the CR the same?

Compression ratio is nominally the same. I haven't seen bore and stroke in print yet, but bore remains unchanged at 102 mm while stroke is increased from 77.5 to 81.5- the same stroke dimension as in the original 3.6L 9A1 base 997 Carrera. I suspect the extra chamber volume came from the new pistons, but that's just a guess.

Interpreted this to mean there are screens under the vents to keep stone/debris from flying up thru the vent while on public roads, but which could be removed for track work to produce improved lift reduction (better airflow).

If not, it's just a gimmick i'd rather not have.

I will use it on the street for speed trap area's...set it and at a push of a button, you are going your desired speed.

right Pit Lane sounds soo much better than "1 touch cruise control"
