Sean73 Posted October 8, 2003 Share Posted October 8, 2003 On my T3/T04E turbo, I had to make a custom wastegate bracket and actuator arm. Does anyone have any feel for how much tension I should set the actuator arm at for the first run? For now, I set the arm so the flapper is slightly tight against the WG hole. I will be using a manual boost controller. Also, has anyone tried running compressed air to the WG actuator as a test? I'd like to make sure my custom actuator arm can go through it's full range of motion, and open the flapper completely. I don't want boost creep.

SleeperZ Posted October 8, 2003 Share Posted October 8, 2003 That's how I would initially adjust it. as you are using a boost controller to drive it. You can always go tighter, but keep in mind you don't want to lose the full travel of the wastegate flapper (at least where you would get boost creep).

awd92gsx Posted October 8, 2003 Share Posted October 8, 2003 Well, make sure that it's not too loose against the flapper valve. If it has any leaks at all chances are very good that it will burn a hole through the flapper valve/housing. Quote Link to comment Share on other sites More sharing options...
