I heard it was a 3.4L flat 8, obtained from the porsche motorsports development dept, with whom they are tight. This is the same motor the Hurley Haywood tried to get them to produce for the gt3rs/rsr a couple of years ago.

I still say as I always have that Porsche should move to a flat-8, which would mean a lower COG than the V8, and that would continue the evolution of the 911.
