Today I took apart my Holset HX55V to clock the turbo and see how it worked.
As Darren had predicted it is a sleeve movement type thing that I can only assume acts as an exhaust brake too.
Video of the movement here. Essentially those blades go up into cutouts in the exhaust housing.
My question is twofold.
Firstly when you close up the sleeve will the turbo be spinning faster and then when you open it all the way it be like a normal HX55?
Secondly when you apply boost to the actuator it closes the housing/vanes up and I can't mount the actuator the other way around because of the water outlet. Where could I get hold of an actuator where it's rod is out to start with and as you apply boost it's rod gets shorter.
EDIT:
If you look at the below video and picture it looks like Stav (ex Redline Editor) is running his with just a spring holding it closed then opening under EMP?
