Bmw 520D

[dilla_t]

ok folks so the 520d has an a TwinPower Turbo 4-cylinder diesel engine. Does this Twinpower mean 2 turbocharges or a just a single turbo? I know BMW uses two turbos one for low speed and one for high speed for some models but for 520d does it use two turbos?

any views will be appreciated.

Yeah man, this is the mother of all twin turbo set ups where one snail sits on top of the other sort of like the primary`s humping the secondary..! But anyway.. http://en.wikipedia.org/wiki/BMW_N47

alrighty I found out that 520d is actually having a single variable geometry turbo.
