Supercharger turbo compounds - MFSuper90 - 11-14-2011
So, i will probably never be able to afford to do this, but it still intrigues me how someone would set it up.
If one was to install a large turbo such as an hx40 on a om606 and they wanted it to spool quickly, couldnt they make a procharger/supercharger feed into the turbo to make it spool quickly?
I could very possibly be completely wrong, so that why i want input from all you guys/gals

2 stage or compound turbo?
google that
or rudolf's benz, that one was a super/turbo diesel
RE: Supercharger turbo compounds - iheartboost - 11-14-2011
the most common set up i see is a roots type or twin screw with a large turbo. the superchargers act as insta boost (they are behind the turbos in the intake tract turbo-->super-->engine) so the engine can start putting out alot more exhaust gasses thus spinning up the large turbo faster.
blowing air into a bigger turbo charger wont do much for the spooling, sure it will do a bit but not much because....well... thats just not the way spooling works lol.
RE: Supercharger turbo compounds - ronnie - 11-14-2011
Detroit diesels (the old 2 cycle ones) run a roots blower with the turbo blowing into the blower. That is on the turbo charged engines. Some just the roots blower. I don't have any turbo'd ones in my collection.

E300TSC is doing this very project.

Or check Rudolf's previous project on a 617.

I agree with you iheartboost,
But, Doesn't a sequential twin turbo setup basically just blow air into the smaller charger?
So wouldnt it work with a supercharger in place of the atmospheric turbo?
I looked a little bit at Rudolf's build, i havent read it all though
And i have been trying to keep up on 300TSC build also
Please Correct me if i am wrong on anything
RE: Supercharger turbo compounds - Captain America - 11-15-2011
Yeah I have seen a Detroit diesel. 2 Roots superchargers being fed by 2 turbos!

you are correct in the sequntial turbo setup. the reasoning being because you can over flow a small turbo with the bigger one. (but this wont make the small one spool any faster)
it would work. but im doubting that the turbo will be the small component. typically the super charger will put out less CFM than the turbo and run out of breath up top. (being a restriction if placed before the turbo)
so yea itll work just not in the way he was thinking shoving air into a turbo from the inlet will not make it spool much faster.
RE: Supercharger turbo compounds - MFSuper90 - 11-15-2011
Thats what i was thinking. Unless somehow you could set up a bypass if it created vacuum on the supercharger, i think the turbo would probably choke out on top end.
So in the end Rudolf and 300TSC setup would be better

On this video you can see a merc that has an lysholm supercharger feeding in to an enourmous Holset, and works quit good
, OM606, lysholm 2300AX, holset HE551 and 722.9 trans you start hearing the noise of the car att13min 39sec and soon it comes in to the picture.http://www.youtube.com/watch?v=9oe1V9qEsFE

The sound is very cool
, but maybe it will become annoying if you use it for every day driving
?Do you have any more info or photos of that car?
My guess is that it is the turbo that is feeding the Lysholm.
RE: Supercharger turbo compounds - Allu D. - 11-23-2011
Yes the sound in the car is VERRY annoying, but its still a verry fun car. I belive I have all the existing info on the car exept all the costs :-) because its my friends car and I've been with him helping to build it this summer. And it is definently the lysholm that blows in to holset, and when the turbo spools up then the supercharger just lyes there spinning and dooing nothing. And one more thing, 180cc of fuel burns smoke free :-)

Hi
Anyone can put a high capacity pump and make a lot of smoke, but a good tuner build the engine so it gets enough air in and exhaust out. Then you get a real performance engine without smoke. From the video, it looks like you are that kind of good tuner
Do you have a photo of the engine? It is very interesting so see the tubing from the Lysholm to the Turbo. I guess you have a bypass valve that opens when the turbo kicks inn.
I am planning to build an engine with a turbo that feeds the supercharger, but maybe your solution is better?

Here is a link to a Volvo KAD 44 engine check valve, and it`s a 3 way valve.
The compressor feeds the turbo, until the turbo need more air than the compressor can feed. Then the valve inside the "check valve" opens, and the turbo sucks air straight from airfilter. The compressor also has a electrick clutch "A/C pump clutch style", and is disconected when the turbo takes over!
RE: Supercharger turbo compounds - iheartboost - 11-28-2011
interesting. that would definitely do the job.
and thats a pretty awesome car Allu D. never said it wont work. just ive never seen a supercharger blow into the turbo.
RE: Supercharger turbo compounds - Lance Carbuncle - 11-30-2011
Having a clutch on the compressor sounds like it would work well for full throttle passes such as drag racing, or quickly accelerating to cruising speed, but if you were road racing or driving hard where you were constantly braking and accelerating back and forth, I would think that you would quickly destroy a clutch like that when you have the horsepower that an engine like that would make... wouldn't you?
What about a twin turbo setup (sequential?) with a small fast spooling turbo instead of the supercharger..... It wouldn't sound so annoying at least
Not sure if this would be more or less complicated than a supercharger/turbocharger and if it would increase low end torque as effectively though.
