Dellorto DHLA

[rocky]

I am thinking about fitting Dellorto DHLA carbs to my Fulvia 1.6 HF
What do I need to know before I buy them? Can anybody give me any tips? What about manifolds? Can anyone tell me about that?


Thank you in advance for your help

The DHLA is Dell'Orto's equivalent of the Weber DCOE. The large spacing means that you will need either a special manifold or, the works sometimes used, an adaptor manifold to fit to the original one. Personally I think that this can be a better approach. The famous No 14 Monte-winning car is fitted with a beautiful adaptor manifold for its 48mm Webers, sadly I do not think that anyone is reproducing these adaptors.

There are reproduction manifolds available; however, beware as frequently they are not properly finished and require considerable fettling. A friend bought one that was porous and thus leaked water; not very encouraging.

Best of luck

Thank you for the infomation. It is very helpful.

As a kind of next question, which carbs are better for the 1.6 engine weber or dellorto?

45's or 48?

I would like a (very)fast road /race, so I can use the car on hill climbs and occasional track days and as well as a little road use?

What other tweeks can people recommend?

Thanks

I doubt if there is any significant dofference; as I said, the works used both, so who can say. Somewhere in Turin there is probably an archive ith the necessary information.

I once wrote to the factory about something. Strange to say I never received a reply...

I would suggest that 48s are a bit extreme. 45s should be good, but for heaven's sake have the head gas flowed by an expert and get a decent exhaust manifold!
