• I have not had an opportunity to play with a governor linkage like that with a damper, but if I understand correctly, it delays movement of the throttle input lever to the governor inside the pump relative to the throttle lever you control with your foot.  In that case, for a performance application, you might want to try running without it.  I think you might then find that you have more power (probably with a bit more smoke too) when you suddenly mash down on the throttle, and you might find that the turbo also spools up quicker.  :twisted:  Good luck!

• hey guys
  
  yes you're right about the damper it's designed to make sure u don't
  have any black smoke on sudden acceleration.
  
  I have noticed on almost all of the pumps that i rebuild in my shop
  that the damper is not dampning any more. it is a vw part and i'm
  pretty sure it's not cheap.
  
  i would also just leave it alon or remove it totally.

  Yeah I dont think mine is damping any more it sounds like a knackered boot strut.
  
  I would have thought they'd be available from Bosch? as they make the pumps anyway.
