VNT control

[ginge191]

Excuse me potentially showing my ignorance but for basic mechanical control on a VNT isnt it just a case of having a actuator on the VNT leaver/rod so that as you push boost into the actuator it pushes the rod and opens up the nozzle, I know the there would be alot of fine tuning for that method but my head is saying how hard can it be.

Yeh, again, from what i've read on mechanical VNT vane control, using this method eliminates any different RPM, and you need differnt pressure at various rpm, if you have a full throttle with little RPM to overtake for example, the vanes are opened to full A/R potenital, but that's not ideal, you'd want cloesd vanes, working UP to larger vanes to increae the A/R in increments.

This is my knowledge... maybe a load of balony, but from what i understand from mecahnical vane control, feel free to shread this to pieces.
