Boost Brothers Turbo Install.

Here is a picture of mine:

I like how you routed it back like this Manuel, What size pipe is that and what wastegate are you using ?


Luke's kit just has like a foot long dump tube that comes back from the wastegate.

Wow, that was over 2 years ago and I don't remember exactly, think it is 1.5? will have to crawl under the car and measure, I've changed the WG for a Tial 44mm and the waste flange was a little bigger than the stock 38 dump.

No, I think is 2", I can find out if you want.

 

[JeremyH]

Looks like 2", no worries def a nice touch makes it easier to do with with the hp kit as it has the wg above the a-arm. My gate is all the way in front at the base of the up-pipe to the turbo (on3 piping). Just getting ideas. I will eventually be modding this piping for a more custom kit.

How is everyones wastegate setup?

Mine has a small hose coming from the end of the compressor housing to the end of the wastegate... Is this even effective?


Here is an (shitty) example I made.

I am no artist lmao

Personally, I'm in the "I like the sound of the dumped wastegate" group. It just sounds badass.

Mine wastegates are just connected to intake manifold lines. I have no problem with overboost and it stays closed when it needs to be closed. I never hear it unless I'm at WOT.

That is good. I can start an art collection with your drawings, lol.

So yours are connected around the same place vac line that the hose for the boost gauge is hooked up at?

To me it just seems that the hose coming off the side of the turbo is not getting great airflow so it takes a little longer for 8the psi to get to the wastegat.

 

[JeremyH]

You have it backwards that is the correct spot for accurate and responsive wastegate control. Vac hose should come from the compressor housing to the side port on the wg.

There is no flow, just pressure, and pressure wise that is the point were it is the highest.

Good catch, I did not payed attention to WG port side of the drawing, just where did he hooked it up the other end.

 

[Randy_S_14]

I think I had a kind in the hose from Turbo to WG. I am taking the pipe off of the WG now to see if I like the "dumped" sound

Check you are using the side port of the WG.

 

[PNR Welding]

You will blow that motor up if you have it hooked up like this.
Go to the side port and let the top port vent.

If you leave it hooked up the way you have it, the boost will be pushing on top of the wastegate and preventing it from opening and the turbo will put out all it could.

Check it and make sure it is right.

I have everything connected to a vacuum manifold:

This. The top port would be used for a boost controller.

On a side note, I've had no problems with my wastegates hooked up to the intake manifold. I can't see why it common practice to hook up to the compressor housing. I want my wastegates to open when there is 7-8psi in the manifold, not in the turbo itself. Plus, engine vacuum helps ensure your wastegate stays closed when not under boost. I hear so many people bitching that they can hear their wastegate when cruising. Maybe this is why?

 

[steeda sa]

may this will help you

 

[Randy_S_14]

Ok, I had a kink in the hose and also had it connected to the top and not the side.

I don't know what I would do without you guys... I know I would probably have a blown motor by now...

I am gonna go see if this works and see what it sounds like dumped.

Holy smokes. I wonder how it even opened at all, with boost and spring pressure on the poppet.

Reading that PDF... it doesn't say anything about connecting to the compressor housing. Still waiting to hear why drilling a hole in your turbo is better than controlling the wastegate with true manifold vacuum.

Um maybe bc true manifold vacuum has nothing to do with wastegate operation, Well you asked so here ya go flapjack. Plus no ones drills a hole in the turbo all the big name turbo manufactures ie turbonetics, precision, garret, comp, they all come with the port/fitting on the compressor cover.

Heres a pic of mine as it came standard from precision.

There is so much bad information in this post.

The top port would only be used on advanced dual or multi port solenoids on electronic setups where you have alot of back presusre or are trying to run alot of boost on a small spring (ie 30psi with a 9psi wg spring)

The side port is used when running off the wastegate spring or using a manual bc or basic single port electronic boost controller.


There is only one pro to using the manifold as your wg source and it really isnt a pro imho and thats if you have a boost leak or shitty intercooler you will still get the boost you want to the engine. It is not the prefered method for more than a few reasons. One, its less repsonsive and introduces vac to the wg, wg operation calls for a pressure only source which would be right from the turbo compressor housing. This helps prevent presusre spikes on the wg and ensures smoother responsive wg operation. Also prevents from over spinning the turbo if you develop a boost leak somewhere between the turbo and the manifold the turbo will continue to spin up until manifold pressure is reached to fully open the wastegate. In otherwards the turbo might be spinning fast enough to make 30+psi of boost by the time manifold gets the desired 8psi to fully open the wastegate thus more wear and tear on the turbo.

The wastegate is always shut there isnt enough exhaust pressure to push the wg valve open when crusing/part throttle or under boost(when under boost the wg will only open if the pressure source is hooked to the side port on the wg) If the valve is leaking or not fully shut under these conditions its due to a faulty wg.


If you think about how the system operates you will realize the many reasons why most people with aftermarket turbo kits choose a pressure only source for the wg.(not to mention the fact that the major turbo and turbo kit manufactures reccomend a pressure only source for the wg.)

Just got back from testing and all I can say is... WOW

It is working like it should now and the sound is ORGASMIC!!!

 

[JeremyH]

Awesome glad you got that wg port fixed in time!

Yeah, me too or
