A local shop here, SMG motoring, has done a few twin charged cobalts. The setup they use mounts the turbo remotly where the muffler sits and charge piping is run up under the car. This setup produces nice power with virtually no lag.

But, there are efficiancy problems with the stock intake manifold and raming the air through the SC. That keeps the twin charge car from never being as powerfull as a turbo alone car. But, there is a light at the end of the tunnel. What if you ran a very small turbo remotely, like a k04, and kept a big turbo running off the maifold to make a twin turbo car. You would see very little lag and keep the high end power and efficiancy of a big turbo.

I believe a customer of his with a GT35r sky is planning such a build right now. It's something to think about.

 

i'm about to sell my supercharger stuff. I actually already let the pump and brackets go. I'm so torn haha Twin charge would be so f'ing sick but I just don't know if it's worth it.

I'll hold off on selling the rest tho if I know someone could help me with the bypass setup.

 

ok 3.25 pulley showed up (unfortunately thats the biggest sfphq stocks) it completely eleminated my over boosting before the ecm can open the by-pass valve. now it just creeps boost like it used to cause the damn .55 a/r so im still seeing as much as 24psi up top but much better than maxxing my gauge at 29.5 (who knows how high it really was i wasnt logging)

so things are comming along greatt, now granted i havent been able to sucessfully run a 1-3 or 1-4 pull but iat2's look very promising and well under control and i am on stock h/e and cooling system.

so once that super duper laggy .70 a/r shows up i think ill be golden.



who ever caught the pressure regulator in my pic, honestly i looked a lindsey's car and ever picture i could find of twincharge set-up the answers lie within.

but if you wanna pm me i'll hook you up. im not always on here but im always thinking about or working on my beast trying to make it something special lol...

 

interesting...

 

How is this working for you?

 

can i come look at your cobalt?

 

who? its working great for me. im soo glad i did this. i have the best of both worlds

instant power and never stops pulling up top!

 

Did you get your new hotside on? And the pulley? If so how does it feel?

 

theres one probably.. that twincharged setup they posted dynos of .. still had lag...

 

They need to tune, match, and bypass better. Lag should be non existant.

 

Yea lol. Thats awesome this may be a route i go. I would guess you dont have the whine anymore but that good torque down low still there.

 

when the 2.8 was on it whined a little but not with the stock pulley

just cant hear it through the front mount and turbo and intake tube...lol

 

Yea thats what i was thinking cause if you cant hear it stock throught that air box your not going hear it through all that piping and turbo.
I would love to go this route but do not or can not spend the money to do it now. I got to keep up some lawyer money etc.
I just got my balt back my wife soon to be ex has had it for the last year when she left. I just got it back couple weeks ago sucks cause i spent alot of time putting it back to stock cause i thought she was going to keep it and put it over in her name and pay for it. But she doesnt take care of stuff anyway if I had left it she tore it up the CF pieces and all.

 

anyone here ever heard of Mike Stafford? from Stafford Fabrication?

he is helping me out with a few things, he is responsible for this... http://www.pro-touring.com/forum/showthread.php?t=63662
