V1 Mikes Extended, Full Frame Goblin - 2009 Cobalt LS with 135k donor

A few questions:
1. with the LNF I also got the LNF Fuel Pump. I bought for the LSJ this one.
525LPH Fuel Pump w/ Installation Kit - Automotive Performance, QFS-525FT-812D High Flow Fuel.

Is it better to stay with the LNF fuel pump or the aftermarket?
When do you hit a limit from a fuel pump perspective?
I saw on the electrical diagrams that there are 2 fuel pumps. Does the LNF has 2 or am I reading the diagram wrong? It also looks like the LNF has a fuel pressure sensor, I don't think the LSJ has that.

2. Exhaust for the LNF. It seems like the Engine has an aftermarket Turbo. On the Turbo I saw AR50 M12. Is that Turbo better as the standard Turbo?

3. As far as I see it the Turbo doesn't have a flange to attache an exhaust. It seems like its made for a short hose, then an exhaust. I see her on the forum a few pictures where people connected directly an exhaust with and without a muffler,... A) Do I need this short hose to decouple the vibrations? B) How much does the Turbo makes the goblin quieter? ( I have my LSJ with 2 mufflers, but it's still so loud, that I can't hear the supercharger anymore )

I believe the LNF has a standard, in tank fuel pump and then a High-Pressure fuel pump attached to the engine.

GearHeadz Garage just went through a HP fuel pump diagnostic, so watch that and you'll get a good idea where it is.

Question 2 is for someone else. I cannot help with turbo specific questions.

Question 3: The exhaust attaches directly to the turbo outlet is the best I can gather form the question. It looks like this below, your LSJ exhaust will not work unless you get this flange added on. ZZP sells a full Goblin Turbo exhaust for $850. At least this photo will give you a better idea of it all, the red circle is where ti bolts to the turbo.

Checked the engine, i found the 2nd fuel pump. Will look for the GearHeadz Garage Video.

Regarding the exhaust, It looks like mine looks different. I am not planning on using the LSJ exhaust, I think I keep it with the LSJ engine.

I do believe that even the ZZP has a decouple element. It looks like my turbo the flange looks different. For a hose clamp or so. Please see this picture.

Another question I have, is why does the ZZP exhaust header has another port (currently capped)? See picture above.

When I look in the turbo I can see the waste gate and solenoid.

Is this part below a mechanical over pressure protection, if the throttle closes, but the turbo is still producing pressure?

Lastly what type of intercoolers are you guys using? Air to Air, Air and water,??? and where do you mount that.

Basically I need some ideas to mount the intercooler and some ideas to build the exhaust.

 

[Robinjo]

Your exhaust is set up for a V-band connector. Any exhaust you use will need the mating band.

The second port looks like an external wastegate V-band port.

The blue item is on the charge piping? If so, that looks like a blowoff valve. A very quick Loogle search comes up with Turbosmart Gen-V BOV.

I recommend you do a little Youtube learning about how turbo systems work. These are basic items that you really need to understand their function and need.

I currently have the ZZP exhaust on the Z57 turbo. I believe you you remove the v-bend adapter you will see the same pattern of the ZZP exhaust.

Yes, that is also correct. You could just remove the V-band adapter.

Thanks! I watched some videos about the turbo, but nothing which gets as detailed as I wanted it too.

I will either see if i can find an exhaust flange which fits directly to the turbo or a kit with a V band connection.

Still interested in know how loud the car is with no muffler after the turbo.

Is there a trick to see all the media files in the forum? If I click here, I see some, but sure not all media files. Need some exhaust and intercooler ideas.

11h in the harness and I would say about 40% done.

Ive got videos on my instagram, under the same name, with just downpipe hanging off of the turbo. Good turbo noises, loud, very deep, not bad sounding like an SC car. I was told it sounds almost like a farm tractor at idle lol

.

technically a turbo is a muffling device. Technically

Found it. You have one with the exhaust you build too? Saw it on the later pictures but no video.

No video with the exhaust on. It brings thr tone down a bit, quiets it down a bunch. Hopefully I will be changing to a piece of 3 or 4" pipe off of the turbo with an exit facing straight back this summer.

Exhaust gases. You smell better with the full exhaust on. The full exhaust carries the fumes away better than a short pipe will.

Any recommendations for an intercooler ?

 

[Rttoys]

There’s a lot of options depending on what direction you want to go in. You can run the stock one up front, put 1 or 2 on the side in the back, hide them somewhere, or go big on the back. Here’s a site with tons of rads for you

Im currently using a Frozen Boost type 16.

If you live in the desert and plan to push a few more ponies than stock, having a little more intercooler is a good thing. A type 15 is the intercooler of my choice.

Ok...

A type 10 is a significant upgrade from a stock DFKC A2W intercooler. I know of two that are using this intercooler at the moment. You'll have to make your own mounting brackets though as the stock brackets dont fit this unit. Definitely overkill for most goblin builds.

Ever lived in the desert and survived the hellish temperatures at the end of July, beginning of August? You cannot have enough cooling capacity for your turbo engine, especially with a healthy tune and larger turbocharger. Having a higher capacity intercooler (mass) and dual heat exchangers - that will have water mist to take advantage of the low humidity evaporation - are a must have to pull the heat out of the intercooler.

I have the mounting figured out for my larger intercooler, so this has been thoroughly thought out already including the path of the charge pipes from the turbo through the intercooler and into the intake throttle body. At some point when I get further along I will post photos of this in my build log. But here's a sneak peek:

Lol, defending yourself on an "ok"? Hahahaha

 

[Desert Sasqwatch]

Just explaining what drives the decision to go with such a larger intercooler and system. When you live 6 inches from sun for 4 months out of the year having as close as possible to adequate cooling is a must have - unless you treat it like a summer 'hybernation' and don't drive.

You can never have enough cooling for your turbo. I actually might look into your type 15. Might work for me better with the Dyemond manifold.
