Alpine Innovations Webcon intake manifold

[ColinLM]

I am searching for an Alpine Innovations intake manifold for the WEBER DGV 32/36 carburetor.
I already have a DGV on my Series V (1725 engine, owned for 7 years) and want to get a little better performance.
I thought I would try "locally" before buying one from A I.

Good luck with that, they are hard to find. I gave up and bought the intake from a seller in UK that sold AI intake a little cheaper than AI. I bought a 38/38 DGES from Pierce Manifolds. The manifold is made for a progressive 32/36, so I had to open up the top a little and alter the spacer. Works great.

Great choice. I put a 38/38 DGES on my Series III GT with a stock single downdraft Solex manifold. I did the proper porting to accommodate. Achieved increased and reliable performance.

What is the trick to getting the electric choke set? I followed the Weber exactly and the thing just will not give me the proper increased idle when it's cold. It's either too much or not at all... it makes no sense!

Would you be interested in a stock Series IV s0lex manifold?

Tom;
Thank you, but no.
I have a Weber on the car now with what I believe is the manifold for the original 2 bbl carburetor (Solex?)
I drive at least 60 miles / week with my club.
It is working fine, but I'm wanting to upgrade.

How about a Series 2 manifold with two Webers. See picture

Thanks for the offer, but I am happy with my DGV.

Having the same problem too though mine works erratically and I think it’s the choke cable sliding abit but I have to really sit down and check.

I have no experience with the electric choke.
Mine is manual, but it does take some tweaking to get it set up right..

What kind of Webers? The source? Have early series III, with twin (I think) Zenith......Dual carbs are kool....

They look like 34 ICT carburettors I'm very curious on how they are configured jeting wise and also the mounting hole spacing , I think they are used on VW motors a bit in the twin set up

Robert was using the VW webrs Iirc.. I can't recall if he bought this setup from a previous forum member ..but in the mid 00's there was a guy playing around with a setup like this and also a setup came for sale on eBay USA.

The nice thing about the twin single throat webers is like you can put them under the stock alpine air filters.

Going to non-stock carb setups is always an adventure in jetting ...and with a progressive carb vs a CD carb the jetting gets much more fine tune sensitive.. and lots of buying of jets... Getting a good ballpark starting point is vital... And having access to a variety of jets to try without having to buy is also a big advantage

DCOE are reasonably easy to get in the window of 80% right then depending on your motor spec and which dcoe you have ( progression holes in the throats of the idle circuit make a difference) you fine tune from there... Manifold and velocity stacks also impact the drivability of them too..

When you start to go to SU carbs.. it becomes more experimental...but those are a CD carb ..so really just finding the right needles and float level....

On the ICT you have half the cost of the DCOE costs.. as you have half the jets to buy .. if Robert has them running well be good to know his settings.

Interesting setup on the Venezia. However I wonder what 34 Webers can do any better than a pair of properly maintained Zenith 36's. Some comparative figures would be great...

I would suspect they are better made than the zeniths and don't have the spindle and carb body issues... Likely also a lot easier to get parts for being a VW OEM carb. And maybe ( don't know) don't weap fuel like the zeniths....

All issues which can be fixed on the Zeniths ;-)

Yes . Problems can be solved... and when working...were the most powerful stock carb setup ..
But even on well rebuilt setups ..I've never seen a pair of Zeniths that aren't weeping after a few months...
Actually..even in period photos you see the marks on top of the bodies and on the manifolds ... .

I suspect the Zenith (Solex is a cousin) design is the ancestor of the Weber. The Webers were offered in a kit by Claude's Buggies for VW dual port air cooled. Weber one barrels always worked well for me, ran sweet too....
