Okay whem im driving out of boost on my mini me setup wit T3 under load and WOT boost gauge seems to stay at 0 for a while then boost takes long to build. Does that sound like a boost leak or is The turbo just a lil to big TURBODA6 told me the Exhaust housing was kinda big and it could b a super60. let me know what u think.

 

More specs on the turbo would help like the size of the ex.A/R. And just double check all the charge pipe connections and also make sure their isnt exhaust leaks pre-turbo.

 

I wish i could tell my self the specs of the turbo but the housing has been changed. i dout its the couplers kuzz i had to strethch those bitches to get them on but i should check them

 

Also what gear/RPM are you rolling into it?

 

If you are not boosting/footis OFF the throttle and the gauge is on 0 bar then you reading the Boost from the Wrong Point?

 

 

boost gauge should show vacuum off throttle.

 

Sounds like it could be a wastegate problem to me. If it's open even a little bit you'll build boost like ***. Make sure your actuator arm is attached to the flapper and the actuator line is good. If you're external then it may be worth popping some allen bolts. So your boost gauge is reading boost, but it just takes awhile?

I know that one time after a turbo install I forgot to attach the actuator arm to the flapper and it was just blowing open under any pressure, so my turbo took forever to build and wouldn't hold it for ----. I also had a vacuum line from my actuator to my MBC blow off and it was doing the same thing. It's definitely worth investigating, but IDK if it's for sure what's going on. Figured I'd at least mention it.
