so i just built a turbo set up and i have a tial external waste gate. at idle the waste gate is dumping exhaust. is this normal?? while cruising down the road its still dumping and barely makes boost. if i accelerate hard and let off the throttle the waste gate closes and is quiet. i dont know if this is what its supposed to do... any help would be great. thanks

 

Something is wrong with your WG. It's not supposed to dump exhaust until it reaches the set spring pressure boost. Mine opens at 14psi. Hope this helps you.

 

Sounds almost like you havent got a spring in your WG. That or your spring is really soft.

 

i will look into it. doesnt it come with a spring when you buy one?

 

Yes it does. Just take it apart and check. It might not be completely seated, and causing a leak.

 

i will do that asap. thanks for the info

 

No problem.

 

I'll bet a dollar you didn't install the valve seat/sealing ring.

 

+1

 

5 bucks says if its the old style he doesnt have the fire ring in which doesnt allow the stem to seal all the way... i no this cuz it just happened to me today haha

 

There could be something wedging your wastegate open.. It wouldn't be the first time I've heard of this happening.

 

do you have a pic of the bottom of the wastegate?

 

any update yet?
