Has anyone done or looked into the prospect of twin charging our cars? I saw the article fomr SEMA I believe where HAHN Racing twin charged a supercharged cobalt. Now its got both the benefits of a supercharger and a turbo. Any idea if this has been put into a kit yet? Also, how much work would be involved in just removing the supercharger and installing a turbo? I know the Pontiac Solstic uses the same motor, and it is turbo charged... :D

dont know,,, but i wonder if we could put the turbo of the solstic gxp or sky redline in our motor or if not put the engine of the gxp in our cars

I got a special edition mag along with another mag I bought a few weeks ago, and it was all about the ecotec motor, and showed all the different variations, along with the solstice turbo motor, and it said in the mag that you could swap the turbo out of the solstic into the SS . Ill have to look for the mag when i get off work tonight and see then if i can find the article on the interent or not. Ill keep ya informed.

Some one has done it to a redline..... search the site for "twincharged"... here you go.... http://www.cobaltss.com/forums/search.php?searchid=39855

Twincharging the Cobalt SS is a nice project but the actual problem is the tuning of the engine parameters, air fuel ratio and timing. Hopefully HPtuners will come out soon with their software.

That seems to be the magical key to unlocking the LSJ's true potential.

He's selling the car for $18.5k right now... it's like 350hp... very sick..

Here is the web site for hahn racing, along with a small post about what they are planning for the ecotec motor. I saw more info on it at the sema web site.

Here is a video of a working model. Twincharged (http://videos.streetfire.net/video/859A6691-B497-466D-85BB-24C296E45939.htm)

Well it maybe a working model, but surely isnt a working video.

translation - link brought me to the site but no video.

well, that answers part of that question. Now, how to get it done the right way using the turbo from the solstice gxp/saturn rl. Does anybody know what i need to do to make sure the turbo stays cool in such a crammed area and with a stage 2 s/c?

Using this turbo would defeate the purpose of twincharging. The idea is to use a large turbo that supplies alot of CFM at a low spin rate. I am using a GT3076R wg. This is a 500hp turbo. The idea is to use the supercharger to bring the large turbo up to speed quick.

Yeah I've seen the twincharged Saturn already, that guy has some money man lol. I believe he also owns an STi and an SRT4.

You mean TwinCharged's car? He does have a race prepped SRT4, not sure about the STi... From a parts perspective, it wasn't too much. Just the turbo, manifold, couple of custom bends, and an SMT6... the tuning was the hard part of it...

MAN I WISH I HAD THAT KIND OF MONEY! :mad:

oooOOOOoooohh....subscribing!

i think this may be the key to a 10 second street cobalt. Twincharging is an engineering miracle.

Did you do this to a cobalt? If so, what's your hp and tq ratings and how did you get the programming done? Teach me all, as I want to know. Imagine getting challenged by anybody and then seeing the look on their face when you destroy them. I NEED TO KNOW!!!

I believe he's workin with someone to produce the kit... be patient buddy, lol!

Good luck on your quest to beating 800hp supras and cobras or 400+hp EVOs from a dig or roll :D

This is FWD world man. Lets not get ahead of ourselves.

Drag radials and BIG axles would definitly be needed to play with the big dogs.

The Turbo shouldn't be a problem, it's just finding a place that would sell it. The Opel Astra (German sister to the cobalt) has a lsj turbo charged engine... so I don't know why they just didn't do a turbo over here... probably cuz this is america

yea, but as twincharged stated already, it would be useless to go with that turbo.

Fortunately that type of money doesn't flow out here. People who have the money don't put into their cars like that, unless they are me. Even a mod'd NSX is getting beat by a slightly mod'd STi. On ocassion we see Vipers and Ferrari's, but nobody is modding them. We mostly have tuned civics, and a few others. But I would love to kill a Viper in a Cobalt. All I'm looking for is 350whp by means of innovation and ingenuity, not just your typical plug and play stuff. But, those are dreams and I'm still completely stock. I gues I might want to get started somewhere.

Plus, I bet that a properly driven and made cobalt could handle a 400+hp Evo, afterall, you don't launch a cobalt by dumping the clutch and slamming the gas.

I am looking at going to E-Town with the car this Sunday May 7th. If anyone wants a look.

i really am not trying to insult you or anything, but a viper can be driven low 12's stock (and thats MT mag, they only give a car like 5 runs) it would be near impossible to get a FWD to go low 12's street tune with only 350 hp

if said 400hp evo were driven as properly as your cobalt, you'd better look out.


so i guess im just saying... aim a little higher... :cool:



edit:... unless... hmmm... weight reduction can make a big difference...

There's always someone faster... that's not the point... the point is he's pushing about 350 whp out of that sucker, and has had MUCH fun mauling the Evo's and STi's around him in a Saturn... ;)

Bureaucracy and politics.

i think you should either hit atco this friday or go to e-town next weekend so i can check out your car ;).

Don't worry about me, I don't get insulted easily. Please keep in mind that somebody has already posted a timeslip in the high 12's in a cobalt and they don't have 300hp. I think they had an Intense Stage 3, which is about 270hp. And you may be right. It may be near impossible to get a 350hp cobalt into the low 12's, but I said 350Whp. Last I checked, that should put me very close to 400hp assuming the power loss to the wheels is about 11% (350 divided by .89= 393hp). Is that high enough? And I'm familiar with the Vipers. My uncle in Oregon has 2 R/T 10 and GTS coupe. I've driven them and the things are powerful enough to start from a stop in 3rd and geared to go over 100 before shifting (the last part I'm assuming), but the also suffer from being a rear-wheel drive. Too much power, and no wieght on drive wheels means plenty of spin, and more power loss to wheels because it is rwd. Evo's...loose more power to wheels than vipers because they are awd, plus you probably need to rev and dump to get it going because you need to get the turbo wound up. Although, and Evo would have a better launch, they are also not geared like the cobalt is in the tranny and the axle size. The cobalt's axle size is 4.05"

how is the viper suffering from rwd? last i checked rwd > fwd for launching since all the weight transfers to the rear. just curious on that one satement you made, it doesn't make much sense.

hey i sent you a PM, i dont want to hijack this thread with racing theoretics.

Thanks Greg, good call.

Well damn I never thought that my original post would blow up this much. LOL. Oh well glad to see that everyone is interested in it just as much as I am. I love my cobalt and truely want to get as much power out of it as I can, and I def wouldnt mind being able to smoke an EVO or STi, or even all the SRT-4's around here. But either way we are all looking for one thing, MORE POWER..... So no matter what you do to get it, were all in the same boat. Lets share our knowledge and all learn from each other. If anyone ever finds out about a turbo kit that becomes production please let me know. Thanks. :D
