ok i got my t3 t4 capable of doing 550 horses now i need the complete guide for twin charging a 2.0 2005 cobalt ss/sc

 

I wouldn't bother twincharging, I'd just do the turbo conversion it's going to be less complex and you'll get rid of the intake manifold bottleneck. There isn't really a "guide" on twin charging, basically to twin charge I guess you'd have to reroute the charged air back through the supercharger inlet post intercooler 2 (a-a), that's the only way you could do it. You can take a look at what zzp has done in their build on their site.

I'm not sure what the safe levels of boost are for the turbo and the s/c but I believe they run larger size than stock pulleys on the s/c so maybe 10-12psi boost. Probably altogether you don't want to run higher than 20-25 psi on the stock block but others are going to have to weigh in on that.

 

yeah troof. dont do a twincharge- it will probably hurt your performance rather then help it if you go with a new intake manifold and an air to air

 

Its complicated, but it won't hurt your performance if done right.

 

waste of money...just go turbo

 

Wouldn't advise twin charging. I hear even if it's done right it usually is way to much maintainance to make it worth it.

 

I say go twincharge especially if its a dd. Do you feel like waiting till 4000rpm for a turbo to spool? I dont. Twincharge = no lag ftw.

 

Its not as bad as everyone says it is. Just do it right and tune it right. Do what ZZP did and have the bypass valve open at 12psi so the turbo is taking over from there. Then have a boost controller set on the turbo for say 20psi and tune it for that. All you need is an exhaust manifold to fit your turbo, the downpipe, and charge piping from the turbo to the SC inlet. Then make sure you have a minimum of 60lb injectors and start the tuning process. Im sure there are plenty of people on here that are willing to help you get the tuning started.

 

 

TWIN CHARGE DOESNT WORK LIKE THAT READ THE ZZP GRAND PRIX GTP POST ON THE TWIN CHARGE KIT!!! AS FAR AS THE IM I JUST BUILT A SWEET MANIFOLD I GO TO DYNO ON THE 8TH/WENSDAY!!!!
THIS IS THE LINQ:
https://www.cobaltss.net/forums/2-0l-lsj-performance-tech-47/intake-manifold-132686/
I'M ME IF YOU HAVE ANY QUESTIONS.
THE TWIN CHARGE WORKS LIKE THIS THE SUPERCHARGER WORKS LIKE NORMAL TO A CERTIAN RPM THEN THE WASTE GATE OPENS AND ONLY TURBO BOOST PASSES! IT'S GENIUS. THE PULLEY CAN BE AS SMALL AS YOUR INTERCOOLER CAN TAKE NOT THE AIR/AIR BUT THE MANIFOLD INTERCOOLER THATS WHY I DESIGNED MY INTERCOOLER WITH A HUGE CORE YOU CAN SEE IT ON THE LINQ. THE WHOLE IDEA IS THERE IS NO SPOOL UP TIME AND THE POWER IS STRONG YET LINEAR LIKE A NATUARLLY ASPERAITED V12 FEEL!!! BASICLY YOU HAVE GOBS OF POWER FROM 1000-8000 RPMS!
THE INTAKE MANIFOLD IS IMPORTANT CAUSE THE LUMINOVA'S YOU DO HAVE TO MAKE YOUR PULLEY BIGGER THEN STOCK CAUSE OF HEAT SOAK!
LIKE I SAID IM ME.

 

I'm not too up on the GTP twin charge system... but the LSJ system does indeed use two boost controllers, and is not at all RPM based.

 

Bump for a complete guide.

 

woah there sparky..

your e-yelling hurts my interwebz ear...

 

True but what I'm trying to say is why not set it up like the gtp twincharge they use HP tunner to offset and onset boost! instead of two boost controllers! Trust me it's alot better then just a turbo with the proper intake manifold.

I'm sorry.

 

I'll only provide a quick schematic. If you can understand this without trouble, then you might survive a chance at twin charging your car.

Red is the existing SC system.
Blue is the additional TC system.
Green is the twincharge control valve.

 

That is pretty good but I would like a step by step guide.

Totally joking man!

 

How bad the heat is at low boost and low rpm with the stock pulley?? (or bigger)

Why not just open the intake manifold, cut the laminova and remove the end plate for a plate to block the hole on the manifold.

Run a big air to air intercooler to cold down the turbo hot air and maybe water meth to help...


What everyone things about that??

 

Funny guy....

How do you plan to cool off the factory heat box?
The M62 is horrible for heat even with the OEM pulley.

 

With larger than stock pulley I don't believe heat would be an issue that would cause problems.

 

i would **** on it instant drop in temps. lol.

ralliartist has proven how much heat the M62 makes and how if combatted you have some nice power

 

The M62 has a dark history of making heat.... anything above 8psi without some type of inter / after cooling is getting a bit too warm for an ecotec.

 

I told you how to beat the heat, omega 5 is right the stocker still heat soaks. You may notice that just by installing a dual pass you can shave tenths off the Quarter mile. Get the drift. When you hit third gear with a stock or larger pulley the heat soak is emense thats what slows us down! The idea behind twin charging effeciently is to not only run an air to air but also to supercool the M62 to make it max effecient then the only hold up is the exhuast ports and exhuast valves not to mention the cam is really only good to about 6500 rpms. But first beat the heat prior to twin charge and the money you spend will actually be worth it.....

 

2. What is the twin charged configuration?

This setup is made for running the blower and the turbo. It uses a different style of exhaust housing on the turbo and works with supercharged or symetrical cams. It requires an intercooler below the supercharger. This setup is recommended for running anything larger than a 67mm turbo. It works well with lower stall converters and can spool up to a 80mm turbo. We ran this setup on our 9 sec street grand prix. It comes with electronics to open the supercharger bypass when the turbo spools.

One of the benefits of this setup is that it allows people with highly modified M90 configurations an easy, affordable upgrade path. By selling your airbox, headers, and 42# injectors, you can make back some of the cost. Additionally, cars running a intercooler can keep most of the existing setup. The twin charged kit works well with supercharged cam profiles. A twin charged setup, given similar mods will always outperform a turbo only solution.

 

Better get your flame suite on...

Although my opinion on Twincharging has not be made yet about 95% of people on this site think Twincharging is a waste. Normally it does not take long for the turbo guys to jump in on these threads and pound them into the ground.

 

I go to the dyno on wensday to find out if my manifold lives up to it's potential.
