It does not work like that. WB (axle position) is not easily changed. The 991 will have its WB changed (100mm longer) since the last change in 1998. It will not make the car a mid-engine car. It will neuter the rear-bias even further, but does nothing re polar moment. Thus, no mid-engine architecture advantage and loss of the unique all-in-the-rear feel. Nothing to like.

Re purists: they would prefer a WB decrease instead.

Thanks for making the effort to post this Rosenbergendo. Smart thinking to corner the guy and ask some questions

None of this would surprise me although that kind of weight loss would be pretty darn shocking and revolutionary for P. I would be thrilled to see it. And a PDK "S" version could well be more weight optimized based upon four years of experience.

A PDK is a joy to drive on track and the performance advantage over a stick is undisputable (yes, a stick is more fun for some, I know).

I have a very nice FVD DFI full exhaust system (that won't throw a CEL, no drone, but is loud) for sale if someone wants to get ahead of the 991 release rush

I need a cheaper GT3. Thing gets more and more expensive by each new model.

I'm sure the cost will go up despite the cheaper 9A1 engine that they're going to drop in. I'll be keeping my old Mezger engine 3 for a long time.

How do you get an extra 20% BHP from the 9A1 without applying the same techniques as those applied to the mezger block? And where is the racing variant of this engine in a cup or rsr motorsport car?

I'll be keeping my mezger 3.8 I think ....

This sounds very interesting. Maybe PDK "S" will be a lighter weight, faster version of PDK? I read in an evo article that Wolfgang said Porsche won't put PDK in the GT3 unless they can find a way to reduce the weight enough. I think PDK-S could be the solution.

Here is a rendering of the 991 GT3 I made in Mexico Blue.



Also, here is another rendering of a 3.4 Carrera I made.

Thought PDK S is what is in the twin turbo, which is needed for higher BHP cars?

The Photoshop is pretty cool ... Although I am not loving the front that much ...

I still want to see a 9A1 variant engine in a race car before I buy a GT3 based on it ... 480bhp or not.

quite interesting - what do they say in general about gt1 block removal reasons? i really do not understand, this engine is pretty much flawless, WHY do they want to replace it with 9A1? just for fuel efficiency?

overall nice news, I am getting ready to buy one in 2-3 years anyway and strip my current car for track fun, so to get a 480hp NA car with PDK will be just a freaking dream come true.

The GT1 engine is MUCH more expensive to produce - it's about profitability. It will be interesting to see what mods to the 9A1 they employ to create 480hp (Displacement increase?, Ti Conrods?, True Dry Sump?, How high will it rev?).

As a 7RS.1 owner I am happy that there is a alternative to bring our cars to 991 rumored engine spec through a SW 3.9 kit. This with Moton CS, toe-links/dog bones, GMG bars should make it a pretty good ride.

Emissions CO2 compliance fuel efficiency and economy of production since giving up the mezger is one less engine type to build ...

I still think they will have to work some to extract an additional 40% output from the 9A1 to achieve 480bhp! And I really want to see a race car with such an engine campaign 1st ...

Regardless is makes the 997.2 a special car given it's the last of the mergers
