That's the beauty of the cobalt, whether you're on the single screw roots blower, a twinscrew, a turbo, or both the cars always run good. And there are a thousand options for each setup and more and more are added every day. I'm glad I bought a cobalt after all....

im with the other guys who said the twin set up doesnt seemt o make sence. if u have the exhaust pressure spooling ur turbo and then that charged air goes through the intercooler into ur supercharger being spooled again and then through the engine back to the turbo where is the gain?

Because post count really matters.....

Not him, but I know him, and I'm a noob to this fourm. I like how you post all these comments about twincharging, when in reality I don't think you know anything about it other than what you've read. You dont know the specs, because you've already told everyone how much he "spent" on his set-up, which is wrong, but doesn't matter. You also can't say anything about tuning, because you don't have a clue what he's doing, or what you're doing either. The only accurate thing you've said in this whole thread is that this car will be insane, and it's Twincharged. So go **** a hat, and stop talking out your ass.

The gain with a twincharge set-up is the super charger spooling the turbo through the engine.
Almost no turbo lag, with max boost at say 3000rpm. The highest power will be made with the proper balance of boost from both.

ok so the belt spins the supercharger that air at say 12psi then goes through the motor comes out the exhaust mani and into a turbo fresh air from the intake then gets spooled to 18psi and that air then goes through the intercoller back into the turbo at 18psi. what happens to the super charger now? i know there are some twin set ups that the supercharger is on a clutch and the pully will "shut off" so to say when the turbo starts to make big boost but on a cobalt what happens to that 18psi when it hits the supercharger agin?

At that point the super charger is essentially useless. It is limited where a turbo can create higher levels of boost. Compressing the already compressed air creates more heat=less efficiency.

the supercharger doesn't compress air like other sc'ers. it basically stacks air and it compresses as the pressure builds up after it flows through the sc'er it never compresses in the supercharger. whipples and centrifugal sc'ers compress air internally.

so you have never seen a full performance exhaust system with different styles of tips available? sad world you live in to focus on that. sure is a public forum doesn't mean you have to be an ******* about someone sharing some info on his buddies setup. if your justification for being an ass is that it is a public forum I suggest continuing as is you wont be here for long anyway.

so then at say 6k to 7k is a twincharge set up usless? if it is making more heat and is less efficienct what would the point be? allso if the turbo is running say 25psi is ther the potenchal to hurt the supercharger? with the point of stacking air. does that mean my 18psi will be stacked on 18psi on 18psi .... so where is the advantage there be? haveing it be 2 stacks of 18=36?

I'm still learning and i have a quick question. The twincharge setup is something that appeals to me. From what I've learned that the S/C will rid the turbo of its lag and give the low end power, and the turbo the low end.

Would one's exhaust system need to be changed with the twincharge setup? And If someone is going to get the twinscrew whipple swap why would it be pointless to have the idea of a twincharge setup?

Thanks in advance for helping a novice learn.

the air doesn't comrpess like it would on another power adder in this case the sc'er isn't going to add boat loads of compression but rather add only a pound if any before the engine sucks it up anyway. since it is already spinning it is just keeping the airflow constant and is just waiting for its turning to do some real work on the low end

so the supercharger gets used 1k-3krpms say 12psi then when turbo hits spools up to 20psi this air is fed to the supercharger but the supercharger has no effect now? would the supercharger still be "thinking"12psi but the air would be at 20psi when entering and exiting the supercharger?

as far as new exhaust u would need a downpipe comming off the turbo dont know if that comes in the kit or not

i believe hahn mentioned that a 3" exhaust setup would be highly recommended with this system. a whipple compresses internally and is extremely good at creating high amounts of boost with very little parasitic loss and can do so at even lower sc'er rpms so there is no need for a turbo at that point since all the power is available at any time. Lots of boost is good but too much is bad all the same.

so then would a whipple compresion be just as good as a twincharge or would one be better then the other form a perfomance point ,dailydriver, strip?

You're right, a large exhaust is almost necessary when pushing higher levels of boost. The faster you can get the exhaust gases out the faster you can get Intake air in. The only down fall is with less back pressure you will lose low end torque.

the sc'er is always in use so as the tc'er spools the sc'er is running and as the tc'er reaches full boost the sc'er is still in use providing what it can though most just passes through.

i believe the general understanding is that a whipple would be a better overall choice. not the best in every aspect just extremely well in most of what you would want

awsome man!!! thats my twincharge kit i was selling on here for a while. im so glad to see this setup working out well. this kit that i sold him was the very hahn racecraft twincharge kit and everything came with it except for the tune and pulley. came with everything i stated in my thread when i was selling it. it was an awsome deal and it is definately a sick setup. im actually kinda jealous lol.

its ok tho project "big turbo skittle" is on its way...i still love the pipm factor of being twincharged though, thats something ill never get in a skittle. at least everyone is happy now!

Ah okay. Thanks. Because in deciding what I wanted, I was either thinking WHipple swap or twincharge, CTI header + downpipe, and hahn exhaust. I hope I wouldn't lose too much low end torque, or make it barely noticeable.

with this car having an issue with traction loss of low end really wouldn't hurt cus in reality you should hook up easier if it takes even just slightly longer for power to come on.
