Car will not make boost. Need some help

[Sprayer84]

I don't know if it was clogged or if it was a manufacturing defect. It's possible in my rush to get it finished, due to me installing it at work, I never had the BC hooked up right from the go. The BC could have been feeding the top but set to a high DC, that bled most off, the whole time.
I'm hoping this is a fix, there are others running this coldside with ZERO issues. If it works but not well I will just have a new coldside made at a local speed shop. Intercooler specs below

Nice specs


Pics please

It's the same intercooler but I'm not spending the money to have this one powder coated.

If you have a friend with a scope, you should peek in your old one. Although, if you found a ball of flattened newspaper in it, you might be irked.

that's making me laugh

That actually crossed my mind because I have a scope. But it's easy to see in the tank with the inlet/outlet. So the obstruction would have to be in the other tank. The intercooler bars have fins inside them though so it would have to be a surgical scope lol.

Get out the sawsall and cut it in half already!

 

[Sprayer84]

Hopefully have an answer real soon!

XU JUN is a busy guy!

Good luck!

No change

 

[one eyed willy]

No change

as in, the problem is back with the new intercooler?

 

[Sprayer84]

Yeah, still getting 17 at the compressor and 5 at the intake

Well, fudge.

So then the intercooler is just a POS? You didn't have any boost drop with the Home Depot bypass right?

 

[Sprayer84]

No boost drop with the bypass.

 

[05stroker]

Wow, so that I/C is loosing 12 psi?

If you want to change your piping around, I have a Procharger I/C for sale cheap in the classifieds if you think you can make it work.

I think it is time for a real intercooler. What does Zimmers have to say, you bought another intercooler that is basically the exact same as they supply right?

I've been in touch with zimmer. I think he's working on something. He wants to get this resolved as well. The hardest thing about getting a new intercooler is getting one that will work with my current piping.

It seems really hard to believe that they have others with no issues though. Maybe they can weigh in on that after they find a solution for you.

Good luck!

Since we're grasping at straws, here's a thought...

Given:

- Without intercooler, boost is normal. A physical check of both intercoolers shows no obvious problem.
- No leaks that can account for lost of boost. Especially since with bypass, boost > 15psi.
- Intercoolers have a nominal amount of restriction and you can expect some equally nominal amount of loss
- PSI is a measurement of restriction, not of flow.

Without having ever diassembled a turbo myself, what if the problem is the turbo itself? Is possible that it's somehow slipping internally? When it reaches the restriction of the intercooler, PSI builds but it begins to slip and can't push the flow past the intercooler?

How off am I?
