Cruising cl***ifieds I see a lot of 2 V and 4 V carbs for sale. where does the letter "V" to represent the word "barrel" come from? If there isnt a traditional reason for it then this might get deleted but I really wonder. Posted using the Full Custom H.A.M.B. App!
So is Venturi plural for more than one venture? I guess I'm ignorant, never heard the term venture used like that.
"barrel" is not a slang term, it is used by almost all manufacturers. "venture" is the same as venturi, he just spelled as he says it..... 4 venturi or 1 venturi, that is just the necked down portion inside the barrel to increase air flow and develop a vacuum signal.
I don't think that is correct. My understanding is that an 'air horn', relative to a carburetor, is the entry p***age to the carburetor body, not the venturi. EDIT: Ah ha.........I just typed, carefully...."venturi" and that $#@&% autocorrect changed it to 'venture'.......but I caught it before hitting 'post'
To get even more technical, the Venturi is named after Italian physicist Giovanni Venturi who described the Venturi effect around 1800. The Venturi effect is the reason the air flowing thru the carburetor ****s up the gas and mixes it with the air. http://en.wikipedia.org/wiki/Venturi_effect

Actually there is a difference in Barrel and Venturi. The barrel of the carb is the entire tube from the air horn to the carb base where as the venture is a restriction in the tube, when the air fuel mix hits the venture it begins to atomize. Some annular discharge carbs actually have holes around the venture where the fuel is introduced into the air stream; the Holly 500 annular discharge carb is a good example. The 4v or 2V designation on this side of the pond comes from Fords head designations some being 4V and others being 2V. The 4V or 2V carb is the European way of calling out a carb where as American is normally 2 bbl or 4bbl (or in some cases 3bbl or 1bbl). Yes the V stands for venturi, and in theory a single barrel could be a *2V if it had a primary and secondary restriction. So in essence barrel would be more correct when calling out a carb like most of us would be familiar with. * there have been stepped carbs built although I can't think if an example off the top of my head
Mine too. Don't sweat it just know what it takes to get your car down the road and forget about all this ****.
That's the HAMB for you. A guy asks a simple question and it's answered , then everybody has to jump in and add their 2cents to it splitting hairs.
I hear ya. I know my share about carbs and venturis. Calling it a venture was new one, on me. thought i might learn something new. So I asked...smile. I see the fella that called it a venture edited it back to Venturi. I'm sorry for any misunderstanding.
this thread ****s .... or is it a atmospheric depression ???? pork and ****** . the primarys on a very late non electric q -jet probably be a good example as it has helpers in the Venturi section to create more signal and mix better .
"That's the HAMB for you..." Yep. Onliest place strong enough to handle this sort of discussion...weaker souls become streetrodders, and buy fuel injection just because their heads hurt after discussing carburetion... Why, just yesterday I was reading a translation of the early works of Porfirio Floatlevelli. Will report my findings, after I finish tuning my Enginecycle.
