Okay so the car was running just fine before all this started happening. one night driving normal i decided just to give it some gas to make sure all is still well with the setup. Well much to my surprise it was not. I gave it some gas and it felt as if i was trying to go fast while holding the brakes down. Boost was building but did not register on the gauge. I decided to let off and there was a blow off but not like the HKS SSQ should sound. I checked all the vaccume lines and they are all tight and connected. Drove it around some more and sounded like the waste gate was not opening like it should. I have a tial 44mm with a 3 pound spring installed. I am pretty new to boost but have a basic understanding of it. Any help would be greatly appreciated.

 

Did you check your intercooler piping?

 

pictures ? ? what set up you running and more details on how the sound sounds ?

 

wouldnt having a blown off intercooler pipe mess his afrs all wack...well at leasts that does mine....i would deff check for boost leaks though.

 

intercooler piping is fine it still is reading vaccume when i go to floor it the gauge just stays at zero and wont go into boost.

My setup is a custom setup what do you need to know about the setup

The sound is the turbo is spooling but the car will not go anywhere. Blow off just sounds a woosh of air instead of high pitch like it normally has and waste gate is an open dump and i can hear it over the exhaust and i cant anymore.

Like before it is as if i floor the car and its like driving with teh brakes to the floor also.

 

WOW, same thing happened to me, I spoke with Toan at ptuning and he helped me out alot. Thats odd and i mean same exact thing. It was my waste gate, there it was stuck open a bit and I heard the turbo spooling up but no boost at all. Heres a picture. as you can see the gap there

 

Also check your BOV, make sure its not stuck or leaking.

 

well there ya go....time for a new wastegate...haha....maybe your kit company will hook you up

 

Isn't there supposed to be a ring at the bottom of the wastegate that seals that gap?

 

Thats what I was thinking as well.

 

yeah there is a ring at the bottom of the wastegate but mine was pushed down so i forced it back up

 

Does anyone know if TIAL wastegates have the ring on the bottom like the t-netics evolution wastegate does?

 

A "Seat", yes they do.

 

thats weired i guess the issue was not my wastegate but when i did take it off and put it back on the car started boosting fine why is that. The ring on my wastegate does close the gap i noticed that. What could It have been ?
