Ok I have never seen this yet on this website. So it is a legitimate question


Would it be possible to Twin Turbo the Cobalt SS/TC????

Flame me if you wish.

It is just something on my mind.

 

with the right amount of money anything is possible

 

Hmm...to add to that, if it is possible, could you add one small turbo and one freakishly huge one? That way the small turbo would kick in quickly to help avoid lag, and then the bigger one would kick in and you'd end up with a lot more boost?
Is this something that has been tried on larger engines?

 

thats the point of twin turbo. lol

 

yes with money......but i'd never do that to a I4 FWD

 

yes BMW also used this one small turbo and one bigger turbo setup on a diesel 3 series I believe.

 

Why do that with two when you can do that with one turbo?

Why do you think twin turbo set ups went away?

They are still relatively small turbos.

 

there are two ways to have a twin turbo setup. one way would be to split the motors exhaust flow to two seperate turbos, another method, which is what I think the cobalt T/C would only be good for, is to put one turbo on and another using the same exhaust flow. only problem is there wouldnt be enough room maybe for new charge piping?

 

listen up jerk, kust kidding,

you could run quad turbo if you wanted to. all you need to do is custom make a header that goes 4 - 4. as long as you have a single pipe for each cylinder, you can split the turbo. google the "ME-412" its made by Chrysler and its a 12 cylinder quad turbo. for every 3 cylinders there is a turbo and it puts out over 1000 horse

 

Oh there is more problems than thinking about charge piping

How about the amount of heat TWO turbos makes.

It is horribly inefficient to run two turbos unless you are making a 1/4 mile pass then letting the thing cool down.

And the 6.5ms window is still there...you can max out performance with a slightly larger than stock turbo...and still you can do what you are trying to achieve win one properly sized turbo.

The veyron is a quad turbo w12, your point is?

You know how much air a 12 cyl engine can push versus a tiny two liter?



You would have to run 4 super small turbos. And probably make less power than stock.

 

lol anything is possible, you do know someone is building a rear wheel drive cobalt. And theres plenty of coalts that are super and turbo charged. But its going to cost money of course. alot of it.

 

im not an idiot dude.

i know victory is building it

ive seen other balts RWD too.

 

This cars problem isn't so much getting high horsepower it's getting a suspension that allows you to use it. With fwd there will always be limitations though.

 

There was a pic posted on here some time ago of a Solstice LNF with the stock KO4 feeding into a GT40R and it had a second set of port injectors and a standalone fuel management system.

 

sounds hot. lol

 

a guy with an srt4 did it so i dont see why not.
i can give u the link if u want

 

There is 3 ways to run twin turbos. Sequential (Supra style), parallel((sp?)2 turbos same size running at the same time), or two mismatched turbos where the feed each other(usually the worest of the 3).

If someone could figure out all the wiring, two stock turbos in sequential mode would provide some really awesome results well keeping your precious spool time. It would take a bit of work to get that setup running though.

 

quad turbo w16

 

You dont need any more CPs if one turbo feeds into the other and i think is is a good idea once we have a decent fueling fix. It is nice to have no lag and ggod lowend but still have a huge midrange and topend too.

 

i was gonna say that. 4 times the cylinders, 4 times the displacement, 4 times the turbos, and a little less than 4 times the HP of a LNF.

 

if you do this your still fucked untill the fueling is worked out lol

 

Why twin turbo it? We already know twin charging is successful... I would say do that. Get you a LSJ intake, SC, tensioner, belt, and a reliable tune and I would say it would be just as good ass the other twin charged LSJ's. I would wait to do this until they figure out the fuel mapping on our cars though.

Twin turbo on a I4 isn't good. Our tiny 2.0L wouldn't push enough air off to spool both turbos, mainly if you go with a 2nd bigger turbo. Either Keep a generously large turbo on it or twin charge it. Maybe ZZP can produce a twin charge kit for the LNF.

I may be missing some things, or it might just be plain and simply retarded.... I was thinking about this not long ago too

 

the technology we have already works like a twin turbo.......
if you read up on how our turbo works.....it works good

 

yeah, our turbo starts spooling at 1400rpms, whats this turbo lag everyone keeps talking about?

 

To add on to my previous post.... I think win charging it with our turbo (K04) would be useless as it is a small turbo and spools at a very low RMP. I would say to twin charge it after a larger turbo is installed.
But I may be wrong. What if there was some kind of clutch system for the SC pully? Like it disengages at a mid range RPM when the Turbo is spooled up, or would that be retarded? maybe a smaller pully?. I thinks that's a practical idea, but has a clutch system for a SC ever been done or thought of?
