k03s turbo question

[Bellic]

i have seen some k03s turbos and some on the outlet side have like a cannister and some dont , what is that cannister for?

 

[Prawn]

im guessing the difference your talking about is the difference in housing between the transverse application turbos, and the longitudinal versions for the a4/passat etc.....

 

[Bellic]

no there is a canister i think it is a muffler

Sounds like the actuator to me, all Turbo's need one to actuate the wastegate flap, it's just some units are sold without them.

 

[Starry]

yeah its a silencer

 

[Bellic]

did some come without it?

 

[simch]

Some with some without. doesn't make a difference for power it seems.

most late ones have it.

 

[Bellic]

so is there to quiten the spoolin

Oh you're talking about the actual exhaust downpipe, not the Turbo itself. It's a pre-cat located close to the Turbo so it warms up faster, this results in better cold start emissions.
