Any pointers to x5 35d power curve

[Owen VEENSTRA]

Hi Gang,

Can anyone point me to something which shows the power curve for a X5 35d ?

(The typical X5 brochure gives power curves for 30d, 30i and 48i but not the twin turbo 35d).

Regards,

O.

Thanx for sharing it Fraser.

Did you make this measurement yourself ? Doesn't seem to be an official BWM doc, so thax for making available something your probably paid for.

The curves looks quite smooth when factoring in the limited number of data points. Do you know approx when (if) the second turbo kicked in (as my understanding is the first turbo is always active but the second comes "when needed" ie your floor the accelerator).

Regards,

O.

This is an official BMW document and represents the operation of both turbos. The intervention of the second (bigger) turbo is dependent on engine load and throttle opening and doesn't happen at a fixed rpm.
