International Lancia Forums

Well it's a beautifully restored car - without doubt.

One observation though: the car would go better if a cold air intake were arranged. So many people have the carbs arranged so that they draw warm air from the back of the radiator - and in this case there are not even any velocity stacks or ram pipes (as the Americans used to call them). These make a difference too.

Note that although it was horribly restrictive, Lancia's original air cleaner housing did draw cool air...

The problem usually is Paul that if you fit Webers or Dellortos then the gap between the rad and the front venturi is almost non existent. In my own case I can only squeeze a sock on the front ram pipe if I pull the rad forward on its rubber mountings !! I suppose fitting curved trumpets might help, but I haven't seen any for sale recently for 45s. I was sent a set that was designed for 40s and was told to file them out for the 45s!! Needless to say I returned them. The std Solex air box is too narrow for the Webers, so you can't alter it and if you made a box would it not be very close to the front venturi and restrict the flow, plus pick up heat from the rad anyway?

Has anyone made a box to fit Webers?

I have noticed that some of the works cars had curved ram pipes that face rearwards, which suppose, was a step in the right direction.

Since the manifold, or adaptor (better) is quite long, I would have thought it was possible to fabricate an air-box, with a large-diameter tube facing forwards with an air-filter on the end picking up cold air from below the RH headlamp.

On cars I have prepared - admittedly with Solexes (ugh!) the normal procedure was to retain the original air-box, but with all the internals removed and the silly hot-air intake welded up. We then added an additional inlet tube with a circular filter picking up air as described above.

Here's a pic of my Weber set up, showing the non-existant gap between the front carb and the rad, which has been moved as far forward as the std bodywork will allow.

I suppose you could try 4 of the "cranked" trumpets that were devised for use in a Mini, by putting them on their side pointing towards the rear. That would put the open end about 2 cm further to the rear, and make a box up to suit. As I said I haven't seen a set of curved trumpets for 45s on the market, even the Alfa guys don't have them.

Certainly the trumpets on Giorgios car are very short, which usually means less torque low down. I'd be interested to hear the engine power, torque and power band numbers? Giorgio can you tell us what they are?

Yes, very close indeed.

I appreciate that most people want to preserve the originality of their cars, but for me one solution would be a light crossflow radiator with remote header tank. This would save weight, improve efficiency and leave space perhaps for an airbox.

The Fulva radiator is very heavy and a pig to remove and refit too. On my car, I can remove the radiator in less than five minutes - and refit it in the same time too!

Sorry for late answer bat im in China now,

So this car is prepared by Giani wich is a wery famous tuner with lancia fulvias specialy for hillklimb preparation, the carburator have not trumbet at all, the radiator is bigger to give better work , the car is completely restored 10 year ago with specification of the period of the 70' .

also the car as a special setup in front and rear, so i told my tha cars have more htne 150 HP , short gearbox , im sorry im not really a specialist in meccanich and also my english is wery bad, any way the car drive fantastick , bat i found the setup od sospention to hard , so inpossibol to drive rally, you need a clean road to drive this car.

Paul, I have these 45mm curved pipes myself. I do use them because of the mesh on them. But I have to say I like the idea of getting the air from the back.

I am thinking of building an airbox that gets its air from the air inlet for the heating system. I have even thought of finding a way to measure air pressure around the nose and bonnet of the car to find a good spot.

Maybe not so important in case of the unequal length V4 of ours, but modern airbox design is focussed on getting the same amount of air to every inlet. This because injection systems assume the amount of air per inlet is equal. In our case, the amount of fuel provided by the jets is based on the amount of air flowing per inlet. So we do not get uneven mixtures, but still it could be benificiairy to create a kind of plenum for constant air pressure. And what I use now looks like Michael's setup. First trumpet almost touching the radiator. There must be all kind of swirls behind that area.

Well, Peter, as I wrote before, my main objection is the warm air from the rear of the radiator.

Coincidentally, I was thinking about plenum chambers he other day. It occurred to me that if I ever have access to a TIG again, I could weld up some bits and adapt them to the Fulvia. It would probably, but not necessarily, mean one throttle rather than four, but as you say, plenums have their advantages.

Also, off topic, I was looking at a BMW M3 engine the other day. 3 litres and about 280 BHP. It has the most wonderful exhaust manifold, each primary being one piece with incredible bends - all mandrel type with no necking. I would love to get my hands on a pair of those: it would be ideal for fabricating Fulvia ones!

...so I'm a bit lost here ... and I know that it's been a long time since posting and now but is the red Fanalone's Giorgios or Michaels?

I interested to note whoever's it is that it is registered in Salerno

Well...so is mine.

Perhaps if you are in Salerno then when I'm there next we could hook up and swap notes. I love to see you car in the flesh as it were and if you are in UK then I could do the same

Anyway Lovely Fana - I must say I do love them all when I work out how to post pic then I'll post some of mine till then

ttfn

oh - it is Giorgios anyway Giorgio I'd love to get in touch with you io anche parlo un poco Italianio
