I saw this car at a show in Ringoes NJ yesterday and thought that some of you might be interested.

Following the path of the intake it is apparent there are a lot of 90 degree angles between the carburetor and the intake manifold which looks to me to reduce the benefits of forced induction a bit. Also, I'm not a turbo guy, but I thought modern turbos didn't like wet flow (draw through from a carburetor).
 
Congrats to the person that pulled it off but, too much going on there for me.....I like Flatheads because they’re simple......Mark
 
I’m missing where the forced turbo air gets into the carb?
From the side? Looks like a regular 4 barrel not a side draft like the Olds Jetfire setup?
Please someone who knows “Splain it Lucy’s”:eek::D

I was wondering the same thing? Looks like it blows into the intake under the carb?
 
Hmmm, After Anthony's post, I went back and looked at it in detail again. I can't see how it works either.:confused:
 
So that setup looks like its off of an old pontiac 301 turbo motor from 1980/1981.

Pretty simple, uses a quadrajet on the adapter, gets pulled into the turbo and then the outlet goes into the intake manifold. Its a "wet" setup made to move fuel through the turbo.

The stock turbo 301 intake just had a round hole where the turbo bolted up to it.

No matter the performance change I would not be willing to put a quadrajet on a flathead V8.

You're right. I tried using a Quadrajet from of a 3.9 Liter Buick a couple of years ago because I happened to have a spare Sharp 4 BBL manifold and a variety of adapters. I couldn't get it to run decently no matter what I did, so I gave up after a while. I think it had something to do with the stack of adapters I had to use just to get the carb mounted. I probably could have made it work by butchering the Sharp manifold, which I wouldn't do.
 
Well, if it runs good, ya gotta give the guy credit. However, for me all the plumbing spoils the charm of a Flatty and that nice high boy. Rather have a super charger....??
 
I don't see much point in putting a big turbo on a low revving engine, but I guess it could have been a "lets see if I can do it" deal.
 
I don't know if it is a 'Big Turbo', but they can be highly effective if the system is correctly designed, things are sized to meet the specifics of the engine and usage, etc..

Keep in mind, that diesels are not high-revving engines, yet every diesel truck I've owned and almost every piece of construction equipment has a diesel engine, with a turbo on it.
