Awd Drivetrain loss is a disadvantage to the 911 so....
Don't forget that the Ferrari motor is bigger at 3.9 and running  20-22psi(pista) vs 3.8L and 17.5psi on the 911.
Did porsche lower the compression from 9.8 to 8.7 on the new turbo(still a 3.8L), thats even less power at the same boost!
I know the answer to this mystery, lets see if you guys can figure it out. Vic has the right idea.... |
992 is running 22.5 psi ......
