Twin turbo?

[dds78910]

Anybody ever tried a twin turbo setup on an 8Valve?

[Frank]

Yes, Carl had a twin turbo 8v shadow... DblTrbl was his screen name

Yeah he has a webpage for it, but I will have to post it when I get home.

His main project now is a crazy quick Neon.

Just thought if would be run to try. I am more at a point where I might be able to try it now. Any pics or info would be great.

[mcsvt]

No prob. I will get you the link unless somebody else chimes in that has it handy. I have meet Carl a number of times now. He definitely tries his ideas.

Here you go:

There's a guy on TD that has a tri-turbo 8V Omni. 2 mitsus, one giant turbo... off of a 14.6litre inline 6 diesel.







The guy says it still cost right around $100 for the whole project so far.

There is no way he spools that big turbo before 6-7K.


ETA: If at all.

The pics are not showing up on my computer, is there any way I could see the pics Dave is showing?

[Dave]

Here, this should work.

dont see the point in that, i dont think an 8v would ever be able to flow enough air and still be efficient

[dds78910]

Yeah, it might have a little boost lag!

[boost geek]

Go through all that trouble and still use a stock intake?

[Dave]

I think the point wasn't to make it efficient and produce huge power. It was more of a cheap project just to "say" he has a tri-turbo with a turbo that's so big it could eat small children and most house-hold pets.

[tvanlant]

Has anyone heard or seen results from this guy? Did it make big power like he was expecting?

[puppet]

Those three turbos look like they're trying to be spooled at the same time. I don't see how this is working at all?

That is because it probably doesn't.

[dds78910]

Here is a setup on a Kenworth truck I saw that might work. The pics are not the best. The primary turbos exhaust is pushing the secondary turbo, and the compressed air from the second turbo goes in the inlet of the primary turbo to help with boost lag. The compressor oulet of the primary turbo goes to the intercooler, and the compressor inlet for the second turbo has the air cleaner on it. I think this would be a practical setup on a 8v.
The other pics are in my gallery if you want to see them, but they are a little dark.

This is what's known as Series Turbocharging, or Compound Turbocharging in the diesel world. It's objective is to produce massive boost pressures, int eh neighborhood of 150-300 psi of boost. It is primarily seen on competetive pulling tractors/trucks.

The idea is that you're using already compressed air, and compressing it more-so. Very much so NOT a good idea on a gas motor in my opinion, since we can't deal with cylinder pressures like a diesel can.

I'm not trying to be a prick or anything, but the picture from someone on TD.com is probably one of the dumber things I've see to come out of the turbo mopar world. Kudos for doing something different, and I'm sure he had fun doing it... but that doesn't make it a smart idea.

EDIT: I just realize from the pictures that his compressor side isn't routed properly either... inlet air is supposed to come in the the large compressor, and it's air feed into the smaller compressors.

I never realized it, but it make total sense, it being named series. It is set up the same way you series wire speakers or batteries. So do you think on a couple of mitsu turbos or some small like that it would produce way high boost pressures also?
