weber or dell'orto/45's or 48's???

[FulviaFanalona]

Hi there everyone,

I have a series 1 1.6HF and would like to improve the carbs for race/rally. I want to keep the solex 42 for road use but want to upgrade when competeing.

What size carbs would people recommend 45's or 48's? and which make, weber or dellorto's? What modifiaction have to be made and what modifications can or cannot be made with regards to historic racing?

Also are there any pitfalls to using certain carbs.

It would be nice if people could give me an indication of what carbs work best.

Thanks in advance

Changing carburettors over is time consuming

Each category of historic racing has a set of rules and regulations which have to be complied with. What is permitted in one series, may be illegal in another.

Generally speaking 45mm carbs is the best compromise. 48mm will generate more peak power but will suffer lower down compared to the 45's

Together with some good cams and a good exhaust (both of which we can supply) a good improvment can be made on on a good solid engine.

Mail me directly for more information.

I found this on ebay

http://cgi.ebay.com/Lancia-Fulvia-Weber-40-45-48-DCOE-inlet-manifold_W0QQitemZ4602037851QQcategoryZ105379QQrdZ 1QQcmdZViewItem


does anyone have any opioins on it?

Is it any good or would I be wasting my money??

That looks like an inlet manifold adaptor rather than a replacement inlet manifold

Our manifold for DCOE/DHLA bolts directly to the cylinder head and bypasses the ineffiecient standard inlet manifold, and creates most space for air filters.

This manifold on Ebay is very cheap at the moment, but bolts to the existing inlet manifold, so you have less space for air filters and also retains the inefficient design of the standard inlet manifold

hi thanks for that - I am sure that Omicron will supply most of my needs re my Fulvia

But can you tell me whether I will be restricted for entry for competiton with the manifold you supply - i would have thought that any group 4 mods would be ok but I wouldnt want a mod if it was just for road use.

thanks

If depends exactly where you want to race.

If HSCC, then anything other than the standard manifold and the standard carbs are strictly outlawed.

Other events have different regulations, you need to read the rules carefully.

However, you can do a lot of work with a Fulvia before needing to change the carbs. Cams / Exhaust / head porting / high compression pistons. The carbs will need to be rejetted to suit. All these are legal within HSCC.

You will find when racing other cars, that Fulvias are so much better in the corners that this makes up for a lot of power or weight disadvantage. In the wet, the handling superiority shows more - imagine driving around the outside of a Lotus Elan!

I agree with Andrew

HSCC will only allow road car spec carbs - What year is your car? If later than 1 jan 1970 then 70s Roadsports regs can be downloaded here:

Fulvias have an advantage in this series - a new class from 1300 to 1600cc where others have 1300 to 2000cc

However, you will have to keep Solex 42s

If older than 1970 then it's the HRS series - again restrictions apply.

On the other hand Top Hat and CSCC have differnt regs:

recommend you also talk to the guys from www.lanciaracing.com
