    Default Dual Carb Caravelle S on Craigslist classifieds in US

    Saw this Caravelle on craigslist and the engine looked interesting. Looks like a possibly homemade dual SU carb set up? Renault caravelle s It is advertised as a Caravelle S. However, I thought the "S" designations were for 1100cc only? Ben

    That's a 1963 FlorideS as the rest of the world knows it, the later 1100cc CaravelleS from 67-68 as we all call it, is what your thinking.

    Ben,
    Please explain what you find good about twin SU carbs ????

    I am very interested, as I am sure a well set up Solex 22 will out perform the SUs and a single twin choke Weber would definitely out perform twin SUs. Even on a 1108cc motor.

    Please respond,
    Ray

    I reckon it is always interesting (I didn't say "good") what people spend precious time doing. Off a wrecked MGB perhaps......

    I have a 22IAC in a box somewhere I'm sure.....

    Thanks Ben for the post, just don't go there.....

    Cat among the pigeons?? Sh!t stirring??

    Shoot me, but I love a SU. Love twin SUs even more! For the best allrounder I'll have a SU. Tops on economy and very very good on performance...............provided you know what you're doing with them.

    Thank you! I absolutely love their induction sound too, especially triple SUs on a straight six.

    A lot of the mini guys are playing with 1.75 single SU's and getting as much, if not more power and torque than a DCOE45.
    The best of them here in Sydney is Graham Russell in North Rocks.

    This will need a new carburettor thread soon. Curious devices.

    In Ray's defence, not that he needs any, he does build engines for purpose, not just for tracks.

    I marvel that such a complicated venturi device works so well, in whatever design concept form it may be. And then to think up any of those concepts, well, just think about it....

    Default SUs V the chokes !

    Hi Ray,
    Just a couple of words in support of SUs. They were cheap as chips in the old days. The old pommie cars died and the carbies could be saved. Lots of people did a quick hot up and gained a few HP for the cost of a simple manifold. If you put them on just as is they would probably go OK. If you changed the needles on them you were an expert and they coud go well. No problem if they too big they just did not open up fully. Very tolerant of mistune and often sounded like they were.
    Whereas hardly any one knew how to tune Webers or Solexes. They usually ran much worse overall after a lot of money was spent buying them. Not to mention they were always choked much too large for a road going 1000- 1300 cc motor. My experiences any way !!

    Back to the car.
    A FlorideS for $600, if only that was in Melbourne and in Aus$, I'd snap it up.
    My 2c worth.

    The best thing about SUs is the fact the choke size was always correct, and the only tuning change is the "needle'.
    Selecting the ideal needle is a little more difficult

    A poorly badly tuned SU always seemed propel the car forward in linear manner. Which can't be said of Webers et Al. Which resulted in pig rooting.

    A major plus is simplicity.

    I had experience with Su carbies on BMC A & B series engines (Mini and MGB) in my teenage years assisting my brother.

    In times gone by I had a single 11/2 SU on my 404 which was very successful in conjunction with a Wade mild cam.

    We ran 2 X 1 inch & eighth SU's on our 850 cc R1063 motored race car back in the early 60's. They weren't big enough and it would have gone better with 2 X 1 inch and a quarter SU carbys. At the time we know we could pull more than 6000 rpm as that is where the taco needle stopped.

    I have a manifold and 2 such SU carbs now, which came off a 4CV rally car that I now own. I am currently replicate an R1063 so probably won't refit them but use a 2 choke down draft. Preferably a 30AAI Solex as was originally fitted to most of the last 30 cars built.(Some had twin Zenith down draft.) Although the top competition rally 4CV's used a "Solex 36? with a concentric fuel bowl to prevent starvation on sharp bends". These may have been twin single barrel side draft Solex's . But finding them, or even a reference to them, has been difficult. All I have is a photo of what I assume are them. A Japanese Solex company built 36's in the late 1960's for motor cycles but I am not sure if they are the same or not.
