Default WG 2.7 CRD Inlet Swirl Flaps

Hi fellow AJOR members,

Would anyone have a picture of their inlet removed? I just want to get a better understanding of the inlet swirl flaps, where they are exactly in the manifold, what they look like, what they're made of, etc.

Cheers, Rob.

If they are still working, I'd leave them in, they help combustion at low loads.

I've saved the swirl flap duty-cycle map in WinOLS. The coolant temperature overrides that, up to 80*C they are open.

Thanks for the pictures. I want to keep them as I think they do work well for low torque. Just been looking at the Maps in the ECU trying to work out what the stock commands are and if I should put them on my "to play with" list of ECU changes.

So with the swirl flaps. Seems there are no long intake runners, or anything like that. Just a port that opens up right at the join to the head??

Is it really that basic?

Where the intake branches off into 2 ports at the beginning, do these ports not got to all cylinders? Almost looks like cylinder 1 gets it's own port?? Can't be right??
