As alot of you know/should know, im getting the Hahn Turbo kit for the 2.4L Auto's here in a few more weeks...


With that said, once its said and done, I am going to rebuild the engine internals, and TRY and develop a twincharge system.

For those of you who dont know what Twincharging is, its a Turbo & a Supercharger on the same engine.


I know theres gonna be alot of issues, and alot of work to be done, however..im bored, and I want something to do..

Besides...I cant let the SS/SC's be the only ones with the twincharge system, now can I?


i'm going to actualy go over the parts needed and whatnot here within the next few days to see if its plausable.

Wish me luck!

 

allow me to stir up some discussion by asking why

pick a properly sized turbo for your engine, build the bottom end & tranny so u can throw a lotta boost at it and be done with it...

twincharging just increases pimp factor, have yet to see it do anything a properly chosen turbocharger can't...

 

pimp factor thats why

 

unless you are into winning car shows then powerwise all you need is a turbo, twin charging is not better than the right turbo on a built engine. but its your preference.

 

yuup, just a fad. it will pass just like 13" gold daytons.

 

uh nah i still want some 14's on my HHR, 13"s maybe not gold though,

 

I want to twincharge mainly for the fact of its "best of both worlds"

Supercharging: For that low end torque
Turbocharging: for that high output of power...

 

Good luck with your project, and don't pay attention to the naysayers who have nothing better to do with their life than bitch about your plans. For those who want to complain about TCarter's plans I say, and

 

GL. as vistory said, dont listen to the morons. tehre jsut jelious that cant afford to FI there car.

 

lol victory, i love that pissed on smiley face.

and thanks for your support.


The PLAN is this: Because I have made some custom parts for the balt, and I love our cars...


I planned on making 2 kits..at the same time. Why? 1 for my car, and 1 to copy and sell.


It'll be one of those, floor it, get that boost from the supercharger, then when that turbo kicks in, even more boost.


and it is "pimp factor"....but you get low end torque (from the supercharger), and high output of power from the turbo.


but i will keep you all informed when i start, i am going to start on it in mid february or so, after i do all my homework on it.

 

More Power to yah, put up your parts list, when you get it, I wanna see. Hopefully you include HP tuners on that and a laptop

 

the only thing going twincharged vs turbo will do for you is take away your traction. if you are looking to win car shows go for it, but performance wise it is a total waste of alot of money. i can see twincharge being a great idea if you were running a massive turbo, but with a decently sized turbo it is just a waste of cash.

 

So I got a question. I assume the air the turbo and supercharger blows meet somewhere (like 2 pipes intersecting). Is there a turbulence issue to consider? If so, how do twin charged systems deal with this?

Thanks.

 

The supercharger runs off of intake air then forcibly injects it into the engine.

The Turbocharger runs off of exhaust gas then forcibly injects it into the engine.

How will it work?

a massive pipe with a funnel type function that will get 2 different air flows meet right before the injection to the engine.

 

how are you going to intercool it. you aren't going to be able to handle anywhere near the amount of boost you are thinking without an intercooler.

 

front mount intercooler, im not going cheap on it.

as well, for ***** & giggles, im going to get a NOS intercooler spray.

but yes, I will keep you all informed when I decide to start on it, im opening up a tuning shop for the cobalts here within a few weeks...

i just ordered a dyno & hptuners

 

I won't hold my breath

 

a supercharger doesn't run off of "intake air" it runs off of the engine itself from a pulley system spinning a belt that spins the pulley on the blower which in turn spins rotors and compresses air. i would not start a cobalt shop without knowing this .

 

waste o money

 

all i got to say is, that will be one giant beyotch to fit in the engine bay. maybe go with a centrifugal blower rather than a roots or screw. i know that in the 2.0 there is like zero room infront of or behind the engine with that blower and heat exchanger/intake bolted on. your gonna need some serious fuel too, so dont forget about the pump, lines, filters...etc. good luck

 

OK.... since i was reading this i have to jump in.... First off, a supercharger DOES run off intake air, or at least it uses it and runs off the engine. It doesnt JUST compress the air, it pulls it from the intake and pushes it into the engine. A turbocharger doesnt push exhaust air, exhaust air pushes IT. In turn, spinning a compressor that pulls/pushes air into the the intercooler/engine. Turbocharger usually ends up being more powerful because it is much more efficient at using the energy put out by the force of the exhaust gases versus actually using parasitic draw from a pulley attached to the engine which is how superchargers operate.

All of you do your homework, or at least post a full thought.

I say go for it man, if you have the money for a dyno, hptuners, and starting your own shop, GO FOR IT. Use the twincharged cobalt as a starting platform to show what you can do. Don't let anyone stop you, although if you come across info that proves it is a bad idea, then maybe you shouldnt. Otherwise, pay no attention to the flamers... I hate trying to get information about turbocharging off of here because ass holes like to come in and talk **** instead of trying to help, then im stuck filtering thorugh the BULLSHIT just to get something useful. good examples... search for anything doing with Hahn's system... i am dead serious, what if I actually have a question? I'm not asking it here.

 

neither system "runs off of" ambient air, that would be totally impossible. they both compress air into the intake manifold and into the engine (unless the blower is a twinscrew which is an intake manifold in itself). you stated that yourself. twincharging is a total waste unless you are running a very, very big turbo. modern turboes are very efficient while they can spool very fast. A properly setup turbo system will have very minimal lag while producing higher power numbers, faster than a blower. unless you are looking into redoing your internals, and spending a rediculous amount of money a twincharge system is pointless. you will not be able to run a turbo big enough to make a considerable amount of lag while still being efficient. you could run a turbo that will make peak boost before 2700 rpm's and still make well over 350 at the wheels, you just have to have the right setup.

 

Well, since we're here, reread my paragraph my friend. I did say they RUN OFF THE ENGINE and not intake air. I'm not foolish enough to think that they magically are spun around by the outside air entering an engine.

You just completely restated what i had posted about them compressing air....

But i do agree with the properly sized turbo.... they're fun! (drove a FAST jetta GLI.. at least 15K under the hood. mid-life crisis car built by a family friend)

 

First off, a supercharger DOES run off intake air


that is what you said and then you said well at least.... you kinda of contradicted yourself, i was just clarifying because there are stupid people on this forum that will take that to heart and tell people that blowers run off of ambient air.

 

I understand that I slightly contradicted myself, if you wish ill go back and edit it even though i corrected my mistake ALREADY in the post itself. And NO IT DOES NOT RUN OFF INTAKE AIR! It runs off of the pulley attached to the engine, which spins the belt, which spins the pulley on the supercharger, which in turn spins the screws inside the supercharger causing air to be sucked in/pushed out. THEREFORE WE CONCLUDE A SUPERCHARGER RUNS OFF THE ENGINE AND USES INTAKE AIR.

Do i need to find a link to some pictures??

Sorry for arguing in your thread TCarter. If you wish to continue playing grammar games and testing technical knowledge, you can PM me 8cd03gro, im not trying to be a hypocrit when it comes to arguing off topic nonsense.
