Current 997 Turbo engine:
-bulletproof design
-tuning friendly despite VTG
-excellent CO2 emissions but, only EU4 norm
-very expensive to build
-slower to build then forthcoming DFI engine
-true dry sump
-only possible with manual(Getrag) and TIP(MB), not suitable for PDK(ZF build)
-almost impossible to switch to DFI
-current SOTA in non DFI gasoline engines
Forthcoming FL 997 Turbo engine:
-DFI with turbo
-different power/torque tuning, truly NO turbo lag any more, torque curve much wider
-little bit more power then current engine
-very friendly for PDK and all networked engine system(much more then current engine)
-integrated dry sump with 4 pumps(if P. Gods are listening true dry sump is possible solution)
-amazing CO2 emissions, EU5 and lowest USA standards as well, less emissions then Audi S5 for example
-very cost friendly for P. since it is sharing parts with all new DFI family
-will use lower boost and higher compression ration for more power/torque
-will be very hard to tune(rumors say NO tuning any more)

That's pretty much my thoughts..
As for the tuning part, im sure there's going to be a way to tune the car! If not for HP (because really where's that's going to go. 1000+ HP?... NO!) Tuning will shift from the engine to other aspects of the car such as weight and suspension..

they have a rich history of cutting the cajones off models... nows the perfect time, imo, with the full court hybrid press and greener is more marketable...diesel panamera in the wings...if youve ever wanted a real tt dont procrastinate

Roadtrip, I think you mean "cojones" which is Spanish slang for "testicles". "Cajones" just mean "big boxes" with no masculine appendage connotations. Take it from me, a Castilian speaker. Cheers!

Then you have "Ramones" which defies definition but might or might not have to do with balls.

If you recall they mentioned (Porsche.com) that they have a new oil pump system that is not dry-sump but something new also in the video clip that showed the whole engine was turning and twisting like crazy with no dry-sump pump.

Don't forget PAG is under pressure to reduce fuel consumption, increase power, and reduce carbon emissions all at the same time. It appears to be an impressive achievement, only time will tell.

At Parade I attended the PCNA technical presentation and can speak to the new oil pump situation. The new oil pump has two stages, a) full pressure (the default) and b) reduced pressure. It's controlled by a solenoid. The fail safe mode is full pressure. This is the same as for current units. What's different is the reduced pressure mode. They've found most of the time running the oil pump at 100% is wasteful, for both horsepower and efficiency. Going to the two stage pump gave them, IIRC, 2% more horsepower and reduced fuel consumption a bit, too. He also explained how they changed scavenge pump numbers and locations, but I wasn't taking notes so I'll not attempt to paraphrase him (it was 80 slides total).
Remember this new engine is nearly all new. They've reduced moving parts by 40%. The DFI heads are just icing on the cake, a lot of the efficiencies came from other optimizations. The entire intermediate shaft is gone, the cams are now driven from the crank via chains. It also has a lower center of gravity and lower mounting points.

Agreed. Not gonna be a problem with the first year editions of the engine.
Gonna be a problem with _all_ the engines after a few years.

Sorry bro, but that's really lame. You are purely speculating and likely speculating very wrong. Not to beat this issue any more dead than it has already been, but although POSSIBLY not as mod reliable, the new engine will likely be as reliable as the old if kept unmodded. Sorry, but I don't believe that the sky is falling.
