Thought I would askhere due to the traffic. As I try to figure out my boost leak issue my next plan is to remove stock waste gate actuators and put on some 1bar actuators. Anyone have some lying around that they dont need that was to unload them?

 

Can't you just test yours? Get a vacuum/boost pump and throw some pressure at them to see if they are actuating as designed.

 

Yea, I have a couple of stock actuators and they seem ok but crack very early so the springs seem week especially for my current turbos at 1.3 bar. Last night I cranked the actuators tighter and was able to see more boost with better response so I think a set of 1 bars are called for.

 

NICE!! Yea usually those style actuators are weak and start to move early...bleeding off boost. Plus sometimes there's some inherent play in the diaphragm vs actuator response. In general..most of the time they suck. I've seen some mods to strengthen them...helper spring, etc.
