    911 DFI power increase estimation

    Quite not academic, but anyway:

    The "old" Cayenne V6 3.2l was producing 250bhp.
    If we could increase that engine to 3.6l and we keep the same bhp/liter ratio, than the non-DFI 3.6l V6 should have approx. 281.25 bhp.

    We know that the new DFI 3.6l V6 has 290bhp.
    That's about 3% more power than the our "estimated" non-DFI 3.6l V6 (281.25bhp).

    If you apply the same logic on the CayenneS you get about 6% more power but that engine has more cylinders and a bigger capacity. On the Cayenne Turbo we don't know how much the new turbo system affects the power so I wouldn't dare to speculate.

    Of course I know that this logic doesn't take under account a lot of parameters but still I believe a minimum of 3% will be gained.

    On a 325bhp Carrera we should get at least 335bhp (10 more).
    On a 355bhp CarreraS we should get at least 365bhp (again 10 more).
    On a 385bhp CarrearS+X51 we should get at least 396bhp (11 more).
    On a 415bhp GT3 we should get at least 427bhp (12 more).

    Knowing Porsche's philosophy I wouldn't be surprised by one of the following two marketing strategies:
    A. 5bhp more for the 997C2, 10bhp more for the 997C2S, 10 more also for the X51 and 15bhp more for the GT3

    or more optimistic

    B. 10bhp more for the 997C2, 15bhp more for the 997C2S, 15 more also for the X51 and 20bhp more for the GT3

    If you still need to keep dreaming you can imagine a 5% increase instead of 3% but somehow I don't feel that coming.

    Bottom line: for sure I believe we will get 10bhp on a 997C2S. But I would love to see Porsche making a surprise to their core 911 fans with 15bhp on an S and 10bhp on the standard car.

    I also believe that would be more important for the engine to rev faster because of the DFI than 10-15bhp more.
    Or how about some panels made of aluminum?

    Re: 911 DFI power increase estimation

    If that can be of any help, Porsche added 13 hp on the 993 and 20 on the 996. Anything between 15 hp and 30 hp is a reasonable bet.

    Re: 911 DFI power increase estimation

    I would like to see the predictions of increased mileage with this new technology. 1-3 MGP should be easy to achieve as well at 15 hp.

    Re: 911 DFI power increase estimation

    A Cayenne it's a heavy car so it's hard to predict a 911 DFI mileage based on that.

    Usually the mileage stays the same despite of the power increase and the reduction in CO2 output.
