So I have a PTE 5557 and am using a Turbosmart bov and wastegate as well as the stock boost controller.

My question is this, what is the correct way to route the vacuum lines for the wastegate and bov??? The way i have them set currently my car will boost 20psi strong. But if i switch two lines around on the bov solenoid (the one mounted on the intake mani) then i fly to 30+ psi and hit fuel cut and yadda yadda. I have literally tried every possible way and have looked at numerous pictures of other ppl's setups (seems to be many ways to do this) and it seems i am either stuck with 20psi or infinite. My goal is 24 psi. The spring in the wastegate is a 20pound spring (which explains the 20psi previously mentioned). I know there is way to "trick" it to going over that 20psi safely and in a controlled manner.

Could this be a tuning issue? How would a guy set a desired boost in HP Tuners??

Also, if i could get some pictures of your or others routings, that would be greeeeaat.

Thanks!

I have my turbosmart bov t'd into the manifold and bov block off plate. Bov line is just looped on intake manifold selinoid.

 

So then that is pointless cuz there is no air movement there. So basically your bov is just connected to the intake mani and it T's off onto the solenoid? Which port of the solenoid??

 

Bump!

 

It's safe to say that when you're boosting 30+ psi, you're waste gate isn't working, so that's the wrong routing. The 20 psi routing sounds like it's right. Someone else had this issue with being limited to 20 psi. I'll see if I can find it.

 

That's what I would assume but what's odd is that when I leave the wastegate routing alone and try different option with the bov lines..that's when it will go from 20 to 30+...

Should the two solenoid or systems (bov and wastegate) being connected in any manner with vacuum lines?

 

Bump...need this figured out! Any help is appreciated!

 

A 20psi spring is a bit much, if you're going to be using hptuners the ecm expects that there's a ~8psi spring in the wastegate, otherwise your airload table is going to need some major changes.
As for the vacuum line routing i'd keep it simple and get rid of that bpv solenoid on the intake manifold, you'll need to plug up one the ports near the tmap sensor on the cold side pipe since its connected to the solenoid. Connect the bov directly to the intake manifold, as for the boost solenoid one port goes to the compressor housing as a boost source, the other to the wastegate and the 3rd port is a bleed off back into the intake.

 

What about the other port on the wastegate??

 

And what are the two vac lines that come from below on the front of the engine?

 

The wastegate should have only one port, if it has 2 then check the manual to see what the 2nd port is for.
Not sure what lines you talking about, post a pic.

 

wategate will have 2 ports leave the top open its for a electronic boost controller from my understanding

 

Wouldn't the stock boost controller/PCM be an electronic boost controller?

 

maybe not sure

 

The beauty of the new tables in HPT is you can set the max WGDC. I would start with 10% in the whole table with that 20psi spring. Then bump it up slowly. Try GMS1 DAL settings, with 300's down the highest column to start. You also want to set the Pressure RPM Factor to the highest boost you would want, it will help limit spikes
