twincharge a no go?

[stage3ion]

so for the first time i went to a local cobalt meet and was talking about my plans of twincharging the car in december when its paid off and i have the sky redline as the new dd... i was told that the twincharge does not work and just to turbo the car is the way to go... does anyone disagree against this because i was really looking forward to twincharging my car, if i cant do that im just gonna keep it supercharged

I would think you would see more power with a turbo set up

Twincharge ftw

Why wouldn't it work? Detroit Diesel does it and they seem to work fine and have power all through the RPMs the use the SC for scavenging and the turbo for the top end power wiki it, they are never wrong Twincharger - Wikipedia, the free encyclopedia

It's not that it's not worth it totally, just right now ZZP is in the trial and error stages of it pretty much, they do offer it in house and everything but from what I've seen they still have a ways to go before I'd let them put that in my car.
What it comes down to really is when you want it done. If you want it sometime soon, dropping the charger and picking up the snail is probably the way to go. If you wanna wait out ZZP I'm sure it will be so much better than just turbo alone. I mean comon, get your whine on then blow it off? . hahah.
Personally it works out for me cause I'll be paying the redline off for a year+ before I can touch anything .
Hopefully they'll have it down to a science by then and just drop it in and off I go ahhha.

The reason to twincharge is to get instant low end boost from the blower so that the car will have boost at launch and negate the turbo spool time, so when the huge honking turbo is up to speed, it takes over and boosts the shit out of the engine.

However, our engine will not withstand the air the big turbos used in twincharging put out, and you will still have a supercharger on your car - contributing to parasitic loss, so there's no reason to do it. For a basic example, you will essentially have Paul's (06blackg85ss) car, but with the loss from the belt driven blower on it.

You can easily run a good sized turbo on it, get a safe amount of boost, and still have it up to speed around 3k RPM. That's how the SS/TC and most of the turboed Cobalts work.

Twincharging is pointless, end of discussion.

yea ill prob wait till they have it downpat... thats what he said zzp has cars not running atm, and i can wait i mean i wanted to do it in december because thats when my 3 yr loan is up and shes fully mine... then i was just going to buy a sky redline and use that as a dd and drive the ion when i needed to go faster or in need of more than 2 seats hahah

Twincharging is stupid for our cars.

if i recall correctly our engines are good stock up to either 500 or 700hp?
plus zzp already has that balt running around 450 on next to completley stock and there's also a redline running some kind of twincharge setup on Streetfire.
i wouldn't really say it's pointless. especially after listening to this vid .

Here's Paul's single turbo cobalt. 414 whp 378 wtq

Stock engines are only good to around 300-350 before they start blowing shit up. With a turbo you can reach higher numbers due to the way turbos boost over superchargers (I'm not clear on the specifics - that's just what I've been told). There's no fucking way that car will withstand 440 whp on stock internals for any length of time. I'm predicting a rod through the case.

not to be a dick but theyre obviously better than 300-350 man. My friend bought the ecotec build book for all the sizes and he said GM says either 500 or 700 can't remember which one. this coming from the manufacturer who put our redline at 6.5k supposedly because "it hadn't been proven safe" above that, so i think thats saying something. now for the 2.2 engines like my friend has in his LSSport cavy 300-350 is the limit cause gm didnt put as good of internals in it.
