Engine placement
I just saw this top cut out shot of 991, anyone's got the 997 to compare it to?
I see that engine is definitely moved forward a bit, likes to compare how much vs. 997.
EDIT: I could only find a Turbo/GT2 pic, if you compare, the transmission looks lower on 991 and definitely the engine is moved forward.
EDIT 2: Finally found a regular carrera pic (althought looks like C4, but site said Carrera).

If you draw a line from the begining of transmission assembly to the wheels, the 997 line is right on front lip of the wheel... however, in 991, the line ends up 1/4 of the wheel diameter to the lip... so at least 1-2" forward. For sure there's less rear bias from all reported reviews so far.

I need to find it again, but I remember reading that Porsche had figured out how to make the transmission shorter by 3 inches, and that was responsible for the engine moving forward by the same amount...
If I am wrong, or misquoting, I am sure someone will correct me soon enough.

If one can find a 997 picture, please post so we can compare. I wasn't able to find one.
It is DEFINITELY NOT in the same place, there is a lot more past the axle, more of the transmission... 100% less rear bias based on Porsche's own statements, how much? I don't know.

Who knows!
I am more worried about electrical steering! That could make or break 991 for me... I will hold on to my .1 now for at least another 2 years, then either will get into a GTS or a 991 if the steering feel is not lost.
Maybe in 991 GT3 they fix that and going to hydrolic steering? Who knows...

That is a turbo. Look at the wheel, seats, etc.

Replace the 991 electric power steering pump with a 997 Cup electric power steering pump (997 Cups already run electric power steering)? Not sure why you'd go that route but here you go:
