I put the intercooler and IC pipe on, re routed the hose that was coming off the nipple on the stock lower IC and joined it to an additional line to "T" off into the DV line. When the car tries to make boost, there is this whining or buzzing noise now. I dont go into the boost b/c it doesnt feel good under my foot. Anybody know what I did or didnt do? Thanks. I left hose with the restrictor connected to the stock "T" location and just joined it with another long piece of hose and then I bought another "T" fitting and cut the DV line to the surge tank and spliced the "joined" line into it. HELP.

 

omg... just remove all lines that u setup... The line that was connected to the intercooler was for boost control... what are you doing with your surge tank?

Are you running the Buschur Upper I/C piping with 1st gen blow off valve? If you are, check if the blowoff valve is leaking. I had a ticking noise coming from my boost controller actuator and found out that it was causing the noise because the blow off valve was leaking.

 

Make sure that all of you intercooler pipes are secure. I had the AMS and now the Greddy w/the lower piping and had a hard time securing the aftermarket pipe tat secures to the turbo. Had the same noise!

 

The only thing is its not the piping. I got the clamps on GOOD. Based on my past experieince I would have to say its how I have my boot/vac lines hooked up. I just dont know whats wrong. I wish I could draw a diagram. The "T" fitting down by the turbo is boost, solenoid,wastegate, and boost source off the stock lower IC coming off the turbo. Now with the new setup. The BR lower IC pipe doesnt come with this nipple. I was told to reroute it back into the DV line for the boost source. SOmething is terribly wrong but I did exactly what I was told to do. If I could weld in that stupid nipple which should have been there in the first place then I wouldnt have this problem. aaaaahhhh

 

I did what I was told to do. I am not running a MBc but I have a UTEC that has an auxillary boost control that I have "t"'d off into the boost solenoid line That alwasys has been fine. No problems with that. .

 

This noise also comes with a wierd feeling under your foot like that car says stop!! dont do that. your going to break me.

 

I had this problem and I cure it very easily by installing a manual bosst controller set it at 20psi and never looked backed. The car sreams ever since. I had that exact problem because thereis no nipple on the Greddy piping either. Just get a boost controller and u should be good!

 

I would do that but I already have a UTEC that controls boost. I was told how to do it and I thought I had it done right. I am so frustrated.

 

Did it feel like that car didnt want to go? Thats what my car feels like. Its like its fighting me.

 

I solved mine by removing that tubing totally .. remember there's one with a restrictor inside that goes to the wastegate .. you need that restrictor .. that tube will go direct to the boost solenoid.. the get another tube to the manifold (I used the DV reference tube too).. plug that to the other side of the solenoid .. oh yes .. before you remove all the tubings .. note how the tubes run into the solenoid .. which side is for wastegate and which side is for boost reference

oh yes .. the weird noise .. have you checked the flange between the turbo and the pipe ?? mine leaked from there and it made a horrible whistling noise (it was a loose bolt) .. and I can't boost above 15 psi ..

 

The hose with the restrictor is still on the the stock"T" fitting. I bought another fitting to "join" a longer line that I could reach into the DV line with a "T". I put this additional "T" right in the middle of the line that connects my Forge Recirc to the surge tank of the valve cover. Is that right?

 

reason for removing the joints and T's was because the boost reference line is under pressure .. too many leaks to happen on these joints ..

I'm pretty sure the weird noise is a boost leak .. you may not notice anything different when not on boost .. and it may not even leak when not on boost (which was my case) ..

 

Sory I missed a copuple of points, The hose with the "restrictor" was connected to the stock lower IC pipe coming off the turbo for boost source. I removed it and replaced with BR lower IC pipe that doesnt have this nipple. I took a plastic "joiner" and joined this restrictor hose with a longer piece of hose that was long enough to reroute it up to the DV. I took the exisiting line running from the surge tank to the DV and cut it and joined it with a "T" fitting. I then took that long "joined" piece of hose and connected it to the "T". Now it runs like crap. The lower IC is secure and there is no rattling or leaking. We were undser the car and cheacked while at throttle.

My noise is like a whining or buzzing sound. And the car doesnt want to boost. Well at least not correctly.

 

Can you walk me through how the lines should have been done abd whewre connect to etc. Replace lines, reroute lines, remove which "T"'s. Etc.?
