My idea is to install my STS Turbo system in such a way as to copliment the supercharger and the other upgrades. Also to prepare for future upgrades where it may become more significant. As I understand the Supercharger is very strong in the beginning and tapers off as the speed increases and the Turbo Charger is the exact opposite. I want to use the Turbo to keep the PSI constant in conjunction with the Supercharger. The idea I have come up with is to use 2 Wastegate's, the first comeing from the Turbo Charger to controlle the presure from it and another after the point where the piping from both come togather so the psi can be controlled more precisely and adjusted when needed to compinsate for future upgrades. I am not looking to add more horsepower useing the turbo at this time unless able to with minimal effort. All this will be after my TVT Perfermance Package = Custome ECU upgrade, Modified intake, Cooling System upgrade, upgraded Fuel Injecors, 185mm pulley, Upgraded Ignition for $3500. Bringing horsepower to 450+. Aswell as Meth injected. Hopefully right after. so the ECU can be tuned for this aswell. What do you guys think? Any suggestions?

 

I guess you will be giving a whole new meaning to RAM-AIR induction. I think trying to get the two to work together will be more problems then it is worth. I could see doing a twin turbo where you have a smaller turbo feeding a larger to try and illiminate any lag, but a supercharger is belt driven and I don't think it will respond well when you force more air into it, you will be causing turbulance and trying to force air around the twin screws. If you are only running a real small amount of boost just to feed the charger then I think gains will be minimal at best and not worth the money.

 

Don't think the expense and headaches are worth it

 

I was thinking not haveing the turbo push air into the supercharger but after it so that both combine and the 2nt wastegate will keep the PSI constant befor it enters the intercooler

 

I will add my 2 cents for what it is worth. I am talking diesel here but still similar in what you are trying to do.

Detroit uses a blower and a turbo on the V6-92s we have in our fleet. The turbo charger is mounted directly on top of the blower. The trick is that there is a by-pass valve on the blower.

The blower is used for taking off to get moving. Once the engine gets the rpms, and boost pressure comes up from the turbo charger, over taking the blower pressure, a spring loaded bypass valve opens and allows the blower to actually freewheel. The idea is that it takes less horsepower to run the turbo once wound up, but still has good take off with the blower at low end.

somthing like this

 

Our intercooler sits underneath the supercharger, it is not like a turbo set-up with the turbo feeding the intercooler through piping, then into engine. Our system is bolted together.

 

that sounds good to but might be a lil more expensive..not sure

 

The Detroit I speak of has an aftercooler mounted under the blower, in the block.

 

there is no piping between the supercharger and the intercooler?

 

slaps forhead.. ohh ok i see what your talking about ..duhh. hmmm need to rethink this now uggg..tks for the help though hmm

 

Correct. The housing attatching the IC to the SC is part of the IC.

I think your in for a lot of time, hassle, headaches, and $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$. But if you are willing to stick with it it will be pretty awesome.

BTW this was already done on a C32 AMG in the middle east, well except his was SC and twin turbo.

 

+1.......see link: http://autospeed.com/cms/A_1447/article.html

 

omg .. that is exactly what i was thinking exp for the auto shutoff and twin turbo.. but damn.. I guss im not as dumb as I thought ..... just to poor

 

Didn't Volkswagen or Audi come out with a similar setup that they marketed as Twincharger? If I remember correctly it came out last year in Europe on a Golf or Rabbit with a 1.4 liter engine.

 

In the glory days of group B Lancia had also successfully combined a supercharger and turbo setup.
Whilst its not impossible it would make for an extremely tight engine bay...it looks like a whole lot of plumbing to me .


There is also a nifty transparent sketch here:
Lancia Delta S4

 

Hell of a first post.

I love it!

 

Volkswagon was the one that did something similar with the TSI

 

This is the first time I've heard of twin charging the m112 engine, and I really like your idea. I think this could be the most effective way to boost our output over the 400hp "threshold" without nitrous or an overly aggressive high-octane tune. You could probably do this without fabricating new headers or new intake manifold as it will feed directly into the supercharger. I also like the idea of complimenting the stock IHI supercharger's efficiency map.

Some problems I forsee:

increased intercooling - keep the stock air to water core, but supplement it with water injection (because I doubt you could fit an air to air IC somewhere between the turbo and throttle body)

placement of the turbo - there's not a lot of room under the car, and will probably need to use a return pump

tuning - of course, but good thing the ecu already knows what to do with boost.

I'm surprised more people haven't commented on your idea. It's a lot less involved than scrapping the supercharger and going only turbo (eek did I say that?), and surely cheaper than mounting a bigger supercharger and fabricating a new intake.

Keep us updated on your research and progress if you decide to go through. I'm following!

 

There is more complexity here than I would consider, where are you going to drive this extra 50 - 75 hp car? Idont get it unless your without stress and looking for some? Woody
