this is actually a great way to learn because he gets to hear all the different sides and arguements allowing HIM to make the best decision

 

I am going for a speciicf HP number and if twincharging doesn't do it I will change my plan. For now, people with way more experience than both you and I, are saying this is going to get me there. Again I am talking engineers and so we will see soon. As for helping people by going with a wipple the same can be said by proving that twincharging works or doesn't. When I am finished the question will be answered. I have a built motor. I can play with the boost to see where it will work and if there is a limit, where that limit is. I am going to have a turbo so if I need to swap over to straight turbo, I am almost there except for the intake adapter. If someone really wants a whipple let them do it. A Keanne Bell at $5500.US let them do it. Those prices are on top of a built engine and I am paying no where near that to do a twincharged setup. Why? Because I am the first with a "built engine" willing to experiment "for all of us".
Again succeed or fail with twincharging, I will be at 600whp for opening day of the track next year.

 

The main drawback of this configuration is that at high speeds, the supercharger (as it is driven by belts) will increase drag upon the engine, limiting the top end power. The Volkswagen Twincharging System overcomes this by locating the supercharger's pulley on a clutch system, which is automatically engaged and disengaged by the computer. This allows the car to keep its top-end performance and automatically switch to supercharging at low RPM. The only drawback is that the supercharger still creates drag in the airflow system, even when the clutch is off and the turbocharger is on. To overcome this, complex piping must be used to bypass the supercharger at high RPMs.

direct quote i found from some vw thing

basically at higher rpms id bet your losing somewhere around 20-40 whp if not more and raising air intake temps. unless your doin wat vw did, i think you need to rethink or idea or start designing the adapter plate for a turbo.

just be clear that im not puttin down your project at all, im glad your the first, i jsut htink that twincharging is the most inefficent way to get there

 

good attitude to have. i can respect that.

THe idea of twincharging sounds cool, im just not rich enough to afford it =/
victory wanna be my dad?

 

 

Id really like to see how a s/c and a turbo combined could no be better than just a turbo, or a s/c.. btw, i have the engineering degreee.. its probably really complicated to do this twincharge setup so let hahn get it all figured out and tested on someone else.. I imagine they will need clutching systems or something to make it last in the long run.. Also to get the most power gains from the system something needs to be able bypass the supercharger at certain rpms... a better cooling system will be needed i imagine, and bigger fuel injectors depending on the boost you are getting from the turbo..then a reflash to make it al work..

dont forget. once you have the twincharge system you can always go bigger with the supercharger, and turbo.. so u guys saying that its the same to just get a built turbo or s/c... think about a built s/c and a built turbo .. combined... ive never seen this done, so victory get er done.. i wanna see what kind of gains your going to pull out of this. u got ***** being the first one to try it.. much props bud

 

ok, i see this could be a good thread to ask this.. exactly how does a twincharge system work... i know how a turbo works, kinda know how a supercharger works, but how does the 2 of them together work to provide the horsepower?

 

twin charging will only work well when they use it the way vw engineered it. you dont need a degree to know how effiecent they way its been done in the past.

correct if im wrong victory but is ur setup not going to ram the turbocharged air through the blower?

 

Hay Victory how come you didn't have the team working on your car add the clutch system like vw? would it have cost too much to do or what. I just want to know and I also hope the setup works out good for you.

 

I asked about that setup and they told me that at that point it's not really twincharging if you shut off the S\C. Turbonetics has an engineer working with the company designing the twincharge system. My understanding is that Turbonetics is of the same opinion as Hahn, that twincharging will work. Both Hahn and Turbonetics are big turbo companies, with experience I wish I had. I know that if you read Hahn's website it does say use a straight turbo for really big power. It just doesn't give the number they are talking about.
I will be getting some test results from my actual kit in about 2 weeks and I will post more detailed info then. The test is going to only be done at low boost because it will not tested on a built engine, but very soon we will have actual results. I expect we will have results before the "other guys".

 

I guess that makes sence. I have one more question if you can answer it. I'm a noob when it comes to turbos or cars but I'm trying to learn. I just wanted to know how big of a turbo are you running? Would you say it is a big or small turbo?

 

i currently am running a twin charged setup on my car w a 2.85 pulley, 60 lb injectors, and 3 inch dp to a custom dual exhaust, fmic ...so far so good...but the car needs tuning badly and to really be tweaked. the placement of the turbo proved to be a huge pita and a lot of custom work and manuevering went into getting the car to actually run on this set up. i just wanted to post to let people know it can be done.
we will market the setup i have on my car as soon as everything is tweaked and we learn more about it, how it works, etc. kenny who has been working on cars for years really knows the ins and outs of what is done... im trying to learn but its all foreign to me. lol

 

can someone please explain in detail how the twincharge system works lol.. i would really like to know this

 

So Donna you going to play nice and share some of the things you learnt especially what cauesed problems and what I need to look out for when we get to tuning. A PM works fine and would be really appreciated. I am glad to hear that someone else here is going this route. I wonder now that you mentioned that you are working on this if you will have the nay sayers tell you how dumb twincharging is. Of course with you having a cool Cobalt and you being much prettier than I am, they may just all tell you what a wonderful idea you have and great it will workout.

 

I can't wait for you guys to get this dialed in and dynoed... I may just go that route if you see some decent gains... and I'd def go with your setup....

 

Basically the turbo will do it's job and feed the S\C which will still do it's job. At bottom end, no lag just S\C power and at top end where the S\C drops off in effiecency, the turbo boost keeps the S\C boosting insane power levels. This is a very simple explanation because I am not the engineer, just the payee.

***Edited especially for articzap***

 

I would but the temptation to have play house with your step sisters would likely be too great.

 

how the hell does the turbo power the s/c???? this in it self makes absoutly no sense. the s/c can not spin faster then the engines rpms, so how is it powerin the s/c. the s/c will act like puttin a 1" pipe on the turbo expectin it to flow compressed air at a high cfm

 

lol ill def let you all know if i encounter any issues with my setup.
i got some grief from people at FMF this weekend trying to tell me theres no way a stock supercharger for these cars went anything more then about 7 or 8 psi...pshhh.
right ...when i told him my car with the pulley and setup was at 22 psi he almost **** his pants

 

i could be 100 % wrong on this but doesnt the turbo help the sc build boost faster? or did i just make myself look stupid.

 

Who said "powering"? The turbo FEEDS the S\C compressed air (compressed by the turbo) at which the S\C spins that air into the engine. What is your problem with that?

 

Just because you and I are doing the twincharging, doesn't mean we invented the technology, so we aren't expected to know everything.
Yes the turbo helps the S\C push more air into the engine because the "blower" is blowing an already increased supply of air (from the turbo) into the engine.
And thanks Donna for any help and advice you can give from your twincharging experience.

 

you clearly stated in your post that i quoted that the turbo powers the s/c not feeds. can only go by wat u say

 

damnit Donna you got .4 psi on me now... now I gotta catch up...

 

^^^ get cracking boy...LOL
