volvo 340 1.7

Post by **schakal** » 23 Mar 2006 04:27 pm

now this is interesting mate,
does the 440 gl carburettor bolt straight on to the manifold ??
in that case i should have some good gains out of it as my 1.7 seems to produce the same power as your 1.7 with a better carb ,if you know what i mean ???
so in that case i shall get around 100bhp with that carb ,what make is the carburettor ???

The carburator is Solex, but what changes is the dimension of the jets... The bigger they are more fuel you inject.

For example the Solex that the 440 GL uses is 97.5/140

The 340 1.4 is 120/135

The 360 is 120/115

The Renault 5 Gordini is 140/165

Why 360 2,0l has smaller than 1,4l moped engine

There is certain limit how big you can make jets as there is carb throat and it can deliver just certain amount of air now you would like to have air 13 times more than gas to get best power, figure out throat size and maximum amount of air that can pass trough and you can calculate maximum size for jets.

i see what you mean ,i just did not expect that much of a gain from a carburettor . dont know much about them you see.

i asked you what exact carburettor comes off the volvo 440 becuase i found a guy that sells volvo carbs on ebay and is askin me the make and number of the carb . can you help ??

B18K carb Volvo partnumber 3344611 or alternative 3344276.

That is what it is in Volvo desk, but don't know if it has some cisac name/number.

Of course it is possible to drill jets, but better have few spares if doing first time, I have heard that it is quite precise job (difficult).

There's a guy here in Portugal who has a Clio with the 1.7 engine

He wanted more power, and what he do was buy a Sierra 2.0 weber carburator, change the jets an dsomething related with te air in the carb..

The car was running pretty well and very fast

Maybe air emulsion tubes?

In portuguese he calls it "correctores de ar", translated to english is "Air Corrector"

I think that must be jets then, don't know other parts in carb that have values like that?

No, is different from jets.

If i can remember he told that the original value was 200

Putting a larger carb on and having it rejetted is probably a wise move for a mild upgrade. Stick a longer duration cam on while you're at it, but bear in mind that this will make your car more rev-happy. If you have tall gears, that might not be a good thing.

My car was pretty awesome down low with the original cam in it with the huge carbs.

cheers

Only 80hp for the 1.7? I thought it was 90 ish, the number 92 came to mind which someone else mentioned. Anyone know for sure?
