Twin-Turbo system...what is it?
« on: April 28, 2014, 09:31:08 AM »
Anybody recognize this twin turbo setup?? It's a 400 Ci Chevy on a 78 boat. I know the motor was pulled and rebuilt and twin turboed in 1996-1997. I've looked around but cannot find anything about this system.

Anyone recognize it??

So is it a blow through system with a carburetor in that box or is it an intercooler?
I'm not sure what it is but if it was a gale banks system it would probably say it everywhere

No stamping/markings anywhere that I can see on the box. But it's not custom made. The box is clearly manufactured in mass production. It's a blow through, inside the box is the carburetor, no
Intercooler on the system.

Any pics of how the turbos are mounted to the exhaust, also does it have waste gates (pics).

Yeah pictures of the exhaust manifold may help and the risers or elbows

I'll take more pictures of that when I get home. My bad on that. It's waste gated as well as BOVed (see pic of box). The way it connects to the risers also seems very pre manufactured to me. I will post those later. All water jacketed exhaust as well as the turbos are water cooled. I'm very familiar with turbo systems, just can't seem to find what brand this is.

Runs like a bat out of hell though!

I'm starting to lean that way. I'm thinking it's a series of off the shelf parts pieced together into this system. Original owner was a race car driver, so wouldn't surprise me.

does it work?  my only worry would be no intercooler.  it looks like a blow through carb sits in teh box and is directly mounted to the intake manifold.

Runs freaking awesome. Had it in Parker last weekend. Flew out of the water. No need for an intercooler. The boost is set really low. I never got past 4 psi.

Not only may I be able to get the information for you on this, I think I know the dude who built it.

Do the turbo oil dump lines route into the valve covers?

I'm going to post more pics in the AM. I will see where the turbo outlet dumps out. I don't think it's into the valve covers though. Almost positive.

Dan'l

id bet that at 10psi you'll see every single weakpoint of that home built system.  and then you'll have to homebrew some parts to fix it.   4 psi all day.  its a pretty tidy little setup too compared to some ive seen.

Here are some more pics. And the turbos T above the intake manifold and drop down right below the distributor. Not into the manifold.

Yea I don't need anymore than that. It scoots just fine. 4-6 PSI is perfect. I ran 16-18 in my '64 Bug all day long. But that's a very different motor.
