The Great Carburetor & Induction Thread

[55 Fargo]

Hey all,

Starting this thread for discussion and debate on carbs and induction.

So let's hear it, all the opinions, experiences likes and dislikes.

In running Asche built Carter BB carbs and have also ran these in the past.

Stromberg, modern type Carter Webbers, Holleys lets hear your story.

Now lets keep it all civil Boys and Girls, no hitting below the belt.

My '38 Dodge is still running the original Stromberg. I put on a split exhaust on the car and have an Edmund's dual intake with matching breathers and a pair of Carters.

The car starts right up with a touch of the starter, never stalls, has decent acceleration and will go faster than I want to go.

 

I can't bring myself to installing the dual carbs.

Hello 55,

Hope this topic is as successful as your driver topic.  Here's mine but I think most people have read it by now...

My final post was an evaluation of the finished product.

And a picture of the finished product.

[55 Fargo]

Here is my setup.

Asche built Intake and Tru Split exhaust. 2 Carter BB big truck carbs CFM approx 175 each.

Now this is on my tired 228, compression is down and rings are leaking.

The Asche setup is built for my eventual 265 build.

It runs a tad rich but if on the highway for 20 miles plugs look great.

Looks cool and adds a bit of punch.

very happy with it only down side is fuel percolating a few times in super hot weather.

I plan to run the original 1" bore BBR1 on my 201 with a turbo, assuming I can get it jetted satisfactorily.  If it's not up to the task I'll start looking at other options, but hopefully I can open up the circuitry enough to keep the AFR where I need it.  

 

I'll be updating your turbo thread as we move the engine into that second stage.

Draw through I take it.

If blow through how will you make the carb seal?

Im very interested in your idea. 

Hope to see your thread on this topic soon.

These engines really are good candidates for boost.

Nope.  Blow through.  Not a fan of draw.  Working out a plan now....   there are ways.... 

 

there have to be ways....

Already o-ringed the theottle shaft.  Don't want aerosolized fuel sneaking out there.   Not too worried about a little leak around the choke shaft.  It's pretty tight, but a little loss there won't be a major concern.

Is there a reason you don’t want a draw through?  A lot easier and the fuel cools the charge air.

Studebaker had a really good looking solution to that with their '57 Golden Hawk w/blower.  Neat lookin' box over the carb. Polished stainless or aluminum would make underhood look great.

I will make a full report once I install my log manifold.

Blow through will be easier for me to execute.

Ford did the same on some Paxton supercharged cars from the 60s.

Yeah, but Ford's first was '57 using the same supercharger, maybe branded McCulloch, before the name change to Paxton.

 

The air box solves the problem of a pressurized carb's internals messing with the fuel/air flow design.

 

The box allows the external pressure and internal pressure differential which meters the fuel to remain the same.  .

I run a Weber 32/36 2 BB progressive carb I bought off Langdons Stovebolt.  Worked good with jets it came with but after much trial and error I was able to get even better performance with bigger jets.  I also use my stock intake manifold and an adapter, also bought from Langdons.  This carb definitely improved my vehicles power and performance and I don't have to sync two carbs.

Installing dual carter/Webers on an offenhauser intake was the best improvement I've done to my 52 suburban. The other upgrade helped- edgy head/split Fenton exhaust manifolds/ engine bored .040/ overdrive transmission/ fuel system upgrades/ cooling system upgrades
