It doesn't come around often, but when it does you have to take notice.

A Rennlist forum member saw a strange Porsche at his local shop and walked over to check it out.  Lo and behold right in front of him was a new pre-production 991 GT3 undergoing service.  Below are some of the tidbits and shots he came away with after talking to the technicians.

Information after discussion with the test driver and engineers and watching/touching the actual car
It sounds incredible. Exactly like a cup car.
Completely different PDK
Engine is a bespoke motorsports block, and the basis for the next gen Cup engine. Dry sump.
Yes, it's not the DFI 9A1 and it's not the Mezger. It's a new engine!
