What are Webers?

[Matra et Alpine]

as already stated, Webers were the "wet dreams" of every racer in the 60s through 80s.
D'Ellorto's were harder to setup but on some enines could be superiro.

Which brings up THE MOST IMPORTANT POINT ...

a bad Weber is worse than a stock carb.
In putting Webers onto a car, you need to make sure you've a manifold that can match the airflow and not cause fuel-pooling.
You need to get the right jets to match the engine and power you want.
For engines above 1600 a couple of 45DCOEs are the business or if you are serious on race track then 48s give a small additional gain - but can be really lumpy at low revs and NOT for small engines
Watch out for newer Webers as they have lots of emission 'bits' and aren't easy to set up for maximum power.
Jetting a Weber is mroe an art than a skill. If you can't find a standrd set of jets recommended for your engine, state of tune and intended use then you NEED to find a good Weber mechanic with a LARGE stock of jets as often it's "suck it and see" for the fine tuning to opmtimise the jetting.

Some may like exhaust note, but NOTHING beats the sound of a BDA engine GULPING air in when the second barrel opens up

It is an Italian company, still existing today being involved in injection systems, but of course keeping up a department for supplying old parts. It is now part of the Fiat group (which may disqualify it in the eyes of some of you).

Webers are still my wet dream mounted in a BMW 2002 that I so much want to own. And hey! I'm just 26!

Have you ever heard about the Mr. Dellorto Ferrari V12 powerboat?

[fpv_gtho]

i think me personally, i'd rather have them in a Mk2 Escort with a Cosworth 4 banger .....ive always wanted one of those

Generally sidedraughts will give you better topend whilst downdraughts will give better midrange,(unless you go IDA downdraughts which they tend to b used on rotaries and flow an insane amount of air/fuel and love rpm).They are a complete bitch to tune and sidedraughts go out of tune quicker than downdraughts,(once a week I had to tune the side's and once a month for the down's).I went to the library and got an old Fiat manual which gave me perfect rundown on tuning them,alot of work,they have to be set up and jetted on dyno for your car,bitch to start when cold and they guzzle the fuel (except on open road where they r leaner than twin throat stocker!!) but they give good power and sound sweet

Well. I was there when the first 1800 TI, (solex fitted) became the nightmare of the BMW workshops. The TISA racing version had Webers, IIRC, What were the standard ones on the 2002TI?

No about the powerboat.

Not really,I tried both and found the Weber's more fine tunable.The Dellorto's were the poor man's Weber but stayed in tune longer as they were slightly simpler.Weber's gave the best results,if you are patient

Hmm, different reults, 1600 X-flow in Sylva Stryker.
The D'Ellortos gave more even fuel flow over th4e range and kept the power band broader and less 'lumpy'.
BUT it needed a custom inlet manifold as the D's are more temperamental to sitting 'level' than the Weber's.
We're in agremeent that the Weber gives more tunability, but that in itself can be a drawback as the different jets can actally end up 'fighting' each other. So easier to get the peaks higher but harder to get the band broader and more even to avoid a 'cammy' engine.
I think it's important that Blue Spura realises that it's not a fit-and-forget option and that setup is difficult.

I guess they were Webers. But I'll make sure of it.

At the beginning of the Sixties Nando Dell'Orto, the famous motorboat racer, decided to put a 12 cylinder Ferrari engine on a 3 point hull prepared by the Cantieri Timossi shipyard. The hull was designed for inboard races (class 800 kgs).
The engine was prepared by Rinaldo Tinarelli, who was known as "the wizard" , the structure of the hull was made of wooden joists covered with marine plywood.
The engine fairing and the stern fin, both coloured in Ferrari red and with Ferrari markings, became a symbol of power and aggressiveness.

A friend of mine has this model. That's how I knew the boat.

Thanks, I have seen that model before, but had not realised who were involved with it.

The story my friend told me is that Enzo himself has given the V12 to his friend so he could build that boat.

Some Maserati powered 4 cylinders and V6 allready existed in smaller but simillar shapes.

Somehow I seem to remember that this boat was shown on Retromobile in Paris, may be five or six years ago.
