Anybody hear any updates on when the turbo for the supercharged ss will come out? I can't wait I hope it is soon.

 

twincharging is pretty cool and innovative, but still relatively new to the tuning world. it will take a lot to get some serious numbers from it and have it tuned correctly. if you are looking into the turbo world, take off the supercharger and put in a turbo.

 

It would be easier and cheaper to just trade in the cobalt and buy a 2006 WRX STI + a MBC.

 

forget about the supercharger and just replace it with a turbo alone youll make more power

 

^^^ The reason for my original statement.

basically, it's fine and all to DREAM about Bi-Charging. Mosrt of us in the real world see several problems with it.

1. Each Systems (Turbo or Supercharger), by themselves, can produde almost as much as both combined.
2. You will not add the extra weight to the car.
3. You will not end up with twice as many things going wrong.
4. You will not have to spend twice the money + on you Bi-Charged system.

Turbo or S/C, Pick one and do it properly.

There is nothing worse than doing two things well, when you could have mastered one.

 

What if he doesnt want a sedan?

and the cool thing about twincharging is you have BOTH!! while the other guy only has one.

What your saying is kinda like oh well the C6 Z06 is faster than a Lamborghini Gallardo so I'll get the Z06 instead. Hell no, you'd go with the Gallardo in a second just because.

 

thats like comparing apples to oranges. the point of twincharging is usually to go fast, not to look good or for status. but to each his own.

 

i dunno I like the twin charging idea in itself simply because it is unique in its own right ... making power is one thing but at the same time why have one power adder doing all the work when you can have two of them share the work

 

Buy the WRX Wagon...

 

twin charging on a show car would be great for custom points but on a real life daily driver or even racer for that matter its not a reasonable choice and also more money than its worth to do

 

i agree with price and complexity of install and management so for the most part it would be for bragging rights

 

yeah so all the peeps would want to "hang out with you".. Whatever..

Un-Sub

 

twincharging doesnt really do anything. it wont add any more power trust me. i thought it would add more power but it doesnt. as for a show thing it would be kool. i used to work on trucks with the twincharging and it really didnt add much. it adds a bit of power but not too noticeable unless its on a diesel

 

Well I agree with your stetement in principal,

But I'd like to point out that it is not complete.

It has been proven to be a very good power adder, but the level of design and custom work makes a system like this seem too complicated for too little gain over a cheaper easier Turbo or SC system.

 

supercharger makes power down low, turbo up high, mix them togeather and you have power all the time, thats why VW is doing it now on thier stock veihicles.

 

Yeah but the resuslts I've seen aren't all that great, at least what I would have expected for them after doing all the engineering. there is a post on here somewhere about VW doing that, it wasn't that great.

My favorite bi-charging question to screw with peoples' minds...

If you have a Blower blowing 10PSI, and a turbocharger sucking out 10PSI, shouldn't the net be 0PSI? lol

But in reality, what WOULD the end result be?

 

Supercharger runs on intake
Turbo runs on exhaust. they do not cancel eachother out since they run on two opposite things. i personally will be doing the twincharge. i will be helping Hahn racecraft prototype the cobalt ss. my car if still on schedule will be in their shop for 2 days in about a month. on 6psi out of the turbo on a completely stock cobalt ss will be doing 400 whp. i am 80 whp over stock right now. i will have diamond forged pistons also. i plan on turning boost up to 12-15 and running 104-110 octane for a nice 500whp.....ill let everyone know when it happens

 

If you're twin-charging for performance, you need to just stop in your tracks.

Forcing more air to your supercharger won't make it spin faster because it relys on your engine crankshaft pulley and crankshaft speeds (RPMS) to make power. So basically, you're throwing a ton of air at a brickwall that is missing a brick. This missing brick is your only benefit because you're actually bringing more air for the supercharger to flow but it's not as effective as people think. If your supercharger is spinning in 7 PSI of boost, and you're turbocharger is spooling 10 PSI of boost, you're essentially making about 7 PSI of boost into your motor.

Who ever told you this, you need to hit them in the back of the head.

I'll try to put this simply...turbochargers come in all different sizes, trims and styles...they don't all operate the same as far as spool time, efficiency and overall power. You have turbos that could be at 10 PSI faster than your supercharger and make more power. Saying that superchargers give better low end and turbos give better high end is wrong. The spool time of a turbocharger relys on:

1. Size of the turbo (mainly the turbine for how fast it spools)
2. The amount of exhaust flow your motor is pushing

As far as VW making twin charged STOCK cars...I've never heard of this and if they did do this, it's the dumbest idea VW has ever had.

No.

First of all, your thinking of how turbochargers and superchargers work is totally wrong...not flaming but I'll try and explain it to you.

A supercharger (roots style) is belt driven off your crank pulley. As the crank pulley spins, the supercharger pulley spins and turns the blades in the supercharger to force air into the intake manifold and into the motor.

Now a turbocharger runs off the exhaust flow. Basically, as the exhaust is leaving the motor, it travels into one side of the turbo called the exhaust housing. Inside the exhaust housing is a turbine. As the turbine spins, it spins a wheel on the other side of the turbo called the compressor housing. As the wheel spins inside the compressor housing, it compresses air and sends it traveling towards your intake system. The exhaust that spins the turbine, it just travels through the rest of your exhaust system.

With that explained, a turbo doesn't suck in anything...it compresses and a supercharger pushes air.

Now with that said...refer back to my previous statement:

 

The VW way of twin charging isn't the same as the way we would do it.

The VW way will us a supercharger for low end and then shut it off and use the turbo for the high end. They don't depend on each other as a path to the intake either. I am not say it's not any less of a bad idea, but it's not exactly the same.

As for neagating the advantaging pressuzing the air entering the Eaton this doesn't seem to be 100% apparent to me. The eaton doesn't compress air at all, it just moves it from point A to B. As air gathers into point B it builds up pressure. So if the eaton is moving air at 14.7 PSI or 21PSI I don't think it cares. I do agree that it can't do it at 100% efficency.

I also agree it is a lot of tuning but I think it's a cool idea worth the time if someone wanted to pursure it. My plan is to go turbo (only) and in the coming years.

I have heard of gutting the eaton and removing the rotors and using it as a convient intake manifold for boost, since we have the aftercooler inline I think it's a cool idea.

 

i wouldnt invest that much just for bragging rights lol

 

The real reason we are going to twincharging is because we dont whant to have to make custom intake manfolds just to turbo the car. So why not just turbo it as it sits? if it works?

 

Well that's not even necessary to do...

You could easily take intake manifold from a 2.2 base model and have it work fine.

 

The platic intake manfold would be pointless because you would push the limit of it right off the back.

 

How so? He's going to be pushing 400 HP?

You have these choices:

1. Stock 2.2 ECOTEC manifold
2. Stock 2.0 Saab Manifold (alluminum)
3. GM Performance Racing Manifold (log style)

 

the 2008 cobalt is going to be turbo-ed. all you people can say what you want but watch when it comes out.
