this could be a stupid question, but has anyone thought of/ tried taking the two
forced induction systems GM offers, and tried twin charging a cobalt with factory
components and some form of after market tuning?
I just kinda had the idea pop in my head right now...
did a quick google search and didn't really find anything....
so, i was just wondering... might be cool to throw it together (sarcasm w/ the words throw & together)
Twin Charging is stupid. Reason being the factory supercharger system is worthless. The only thing more worthless on a cobalt than the M62 is the cupholders ( I'd like to beat the @!#$ out of the moron that designed those!). Your also stuck using the stock intake manifold which is horrible. If you have a properly sized turbo the only thing that still having a supercharger hooked up offers you is parasitic loss from spinning it and higher intake temputures which mean the ability to run less timing and make LESS power. The pitiful amount of low end torque it might make extra isn't really useable anyway. Turbo cars are much easier to launch and have the better 60 foot times on this setup.
Twin charging is nothing but a show novelty, it has zero benefits over a single dedicated turbo setup thats properly done and will consistently make less power all other things being equal. If it was so great everyone would be doing it, theres a reason that nobody is doing it. Its not because of cost or difficulty its because it doesn't work and its a waste of time. For reasons such as this several vendors including Hahn abandoned the project and went to more efficient turbo only setups.

Dunno if you have seen this before but this is the thread of the dude who did it to his cavy. He got possitive results even though his car kinda broke. lol
BUUUUT.... if you have the money to do that, and want something faster, get a faster car. Because it would not be cheap, and for some benefits, but as has already been said, you are working against yourself. (though you still gain, as seen in this thread)
But of course you are talking about the Cobalt which IS faster stock..so why don't you try it and tell us the results.

In this case, you are probably correct, but don't think twin charging in general is a waste. There are many benefits from it and is a fantastic setup when executed correctly.
i've wanted to do this to my car but i have heard it's a waste on the LNF.
i could see myself investing in custom parts to make it work. and i'm not looking for lots of power either
still in the air. not modding the car anytime soon anyway

on an LNF thats just stupid to put a supercharger on there, it makes peak torque from like 1800-6000 anyway supercharger wouldnt benefit that at all

My local friend's M62 has ran high 12's without any major cooling mods.
His cupholder hasn't.
...and neither have you last I checked.
WTF are you talking about? And who are you talking to? I'm glad your friend runs 12's. News flash for you......thats not fast =/
Joe - its also not a cobalt and its 300lbs lighter, high 12s are fast for a M62 cav or cobalt, for a turboed variant of either its really not. This said car also failed to put out more power on the dyno than my non M62 car
As far as track times I've never really cared, if i did I would go buy drag radials and practice more than once a year, I'm not sure why I need to post that in every single thread. Don't throw out times from other peoples cars to make yourself feel good, you have done nothing in any car you have had.

Actually the car I'm referring to is a Cobalt.
Knocking your @!#$ doesn't make me feel good, however knocking everything you don't own works for you.
wow Rodimus is just looking for a fight isn't he?? lol...
honestly i have considered twin charging before, if you have enough money top do it correctly it would be well worth it as the supercharger would minimize the effects of turbo lag, allowing you to use a slightly bigger turbo. then all you have to worry about is keeping it cool enough

to be honest, neither have you

I took his attempt of knocking me in stride, all my cars have achieved what I've wanted them to and I've never made any high and mighty claims. My work has spoke for itself, more than my mouth ever will.
Some people just don't know when to shut up unfortunately.

Shiny SC's make you fast!
hrmm i dunno increasing power by 50% over stock and increasing gas mileage by 25%, id say thats something
Just because someone does not drag race does not mean that their car isnt fast or powerful

Joe got his cobalt about a month ago. what do you want him to do in a months time? Joe got his cars what he wanted them to do. thats something to him. i got my cavalier to do what i wanted it to do. and you got your cobalt to do what you wanted. that may not mean something to everyone but it means something to the owner.
nobody brought up drag racing but you. but while we are on that subject. you go on any car guys website and say "i have this car. it has X horsepower blah blah etc". usually the next question asked will be "how fast is it in the 1/4 mile?" and going 13.9 @ 110 mph is not fast. saying that it is, is something an idiot ricer does to try to justify his crappy launch or his lack of a driving skill.

talk about a crappy launch XD
haha no problem Cortana... ive been thinking about doing this for quite a while and have done some research into it. If you tune it correctly and keep the air charge cool then it could be very useful.
yea i know i've heard it can work and then theres' those who think it can't.
anything can be done and last with the right amount of money and not be "wasteful" as they say

There was a WRX posted on here a while back ago. It had a HUGE turbo and a S/C. The S/C ran on what looked like an AC clutch. So it spooled the turbo up and at a certain RPM it kicked off the pulley pretty much freely rotated. Not spinning the actual S/C its self. So the S/C was only used for a few thousan RPM's to help spool the large turbo.
haha god your making me wanna blow my bank account and do this now... thats exactly what I had research about two years ago... clutched supercharger to spool up the turbo.... hehehehe I want it =)
