Because that seems to be the rumors the HP are hearing. It might be bucking the trend toward turbos, but I stranger things have happened. What do you think?

I guess that no one knows for sure, but Andreas Preuninger (head of Porsche GT Division) has gone on record in various interviews stating that GT cars will remain naturally aspirated for the foreseeable future to satisfy the purists. The GT2 is obviously an exception to this, but if I had to put my money on it, I'm guessing (and hoping) that it will powered by some variation of a H6.

They have plenty of room to increase HP on the H6. I’d say the Gt3 would go Turbo before the GT4. But you can never predict their strategy.

That sounds right.

The powers that be at Porsche are hinting VERY strongly that the new Spyder/GT4 will both be flat 6's and NA.

Huh.

I kind of expected the new GT4 to have the TT flat 6 out of the current 991.2 "S" (in the same way the previous GT4 had the 3.8 out of the 991.1).
