In the hunt to figure out what in the world is making my turbo howl like it is I've narrowed it down to my wastegate. Reason I say this is because of the slow out of the hole performance of my turbo and the fact that you can hear the spool up of the turbo coming out of the stacks.

Has anyone disassembled one of these before? I was looking at the tech on their website and it's pretty self explanatory but I just wanted to be sure before I go and start tearing into this thing. Any tips on what I should look out for? Should I take the turbo off of the manifold before I start disassembling in case something should fall down inside? I've got a sneaky suspicion that I might have either a weak or broken spring that's allowing some exhaust to bleed off and isn't allowing my turbo to spool up and is allowing the turbo noise to travel through the exhaust.

Thanks yall.

 

Hope you get it figured out blue. Theres no such thing as turbo lag on a stock tranny but once you get a good tight transmission in there you can really tell a difference. Wheres the sound clip?

 

You're running a 38mm, right? Why don't you just pull it off the truck (2 bolts for each flange) and disassemble it on a bench. No reason to pull anything else off. Just be sure not to lose the sealing ring for the bottom flange. It might be sticking open a little bit causing the poor spoolup.

 

Well I took it all apart and found out that the boot on the inside has a nice little circular tear in it from where one of the boost lines screws into it. So between that and the hole in the weld on the manifold that could be causing the slower spool up and howling noise I've been hearing lately. For a temporary fix I went and wrapped the back side of the boot with a couple layers of electrical tape (couldn't get the tire patch to stick) and it seems to accelerate a little better.

 

Is the 'boot' you refer to the rubber diaphragm on the spring holder? If so, that would not account for turbo lag, would it? I would think that would leak air pressure and cause the spring to open latter??
Have not seen the inside of a Tial for long time so I may not remember correctly. But if the bottom air inlet fitting caused the hole, I would contact Tial for a replacement.... which you have probably already done?

Tyler...if you want to figure out if it's the wastegate or not, I have a 38mm Tial I can send you to run and see if it still does it or not

Good idea chris but I need to go ahead and get mine fixed anyway. It ain't hurting anything the way it is. By the way, where's that pillar? I ain't seen it yet?

RJ, that's the correct part. Don't know if it's causing the lag or the noise but one way or another it needs to be fixed and yes the screw on the bottom air inlet rubbed the hole in it. You can see a perfect circle cut into it. I didn't find out about it until yest evening so I'll contact tial on monday morning and ask them.

 

Just thought I'd offer...it's in the box if you decide you want/need it!!

I had to buy another pillar, and he was supposed to ship it direct to you! Let me look into it!

Thanks for the offer and I'll keep an eye out for it.
