    Default R17 twin carb intake manifolds?

    Hi all,
    can anyone recognise these manifolds for a twin carb set up - possibly from a 17?
    They came from a Renault owner but there is no marking on them at all to give any hint of what they would fit.
    I separated them from the set of 45DCOE's that I'm selling in the parts section currently.
    Any ideas let me know please. Appreciate any feedback. They are for sale if anyone wants/ needs them.

    Some measurements would help folk to answer your question.

    The hole pattern looks right on the head side (I assume that is the one without studs), but they seem to be angled up which doesn't make sense. The 807 engine sits in the 17 vertically, so I would imagine the intake should be straight at 90 degrees to the head.

    Looking at R8G engine manifolds however, it seems they are angled up a bit like these as well (the R8G engine sits vertically as well), so who knows?

    That said, I've never seen a set of those in person and I am sure people who know for sure will chime in.

    I do believe they are for an 807 engine, (17TS&TL,16TS,15TS)and I think they were cast in Brisbane about 20 years ago. They were basically copied, to a point, from a genuine pair I had. They were made to be different enough apparently to not infringe copyright. The carbs are angled up maybe 5 degrees.

    The carby body is the same across side draft Webers. The difference is in the venturis.

    That is yes, they will fit. So will Dellortos or any other side draft carbies you want.

    They didn't look right to me Alan as number two cylinder is not shorter than the other three where they bolt onto the head, but after another look I see a third hole drilled into the number two cylinder flange. So they look like they will fit.

    I believe you would have to cut off the lower section of the port face with two holes, as it would interfere with the head casting. The original manifolds were genuine R12G to suit 45mm DCOE, but you could also mount 40s on them with a step from the carb to the manifold. Hp wise with both 45s and 40s with 34mm chokes, as you would expect the low down power was perhaps a little stronger with the 40s, and minimal difference at the top end with the cams and revs I was using.

    To get any real value also need to enlarge the inlet valve diameter.
    With the DCOE I fitted had great top end power and smooth delivery
    But, around town at low revs the car was a bit of a dog, matter not, depends what you are after.
    The bigger inlet valves made the best improvement

    That's the down side of carbies, very difficult to be good every where in the rev range. Where as with fuel injection and proper mapping a lot of these problems can be tuned out.

    Especially when mated to hot cams.

    Dave C shared similar experiences of driving the 12G in traffic.

    On the other hand, good results can be achieved with (relatively) modest carbies if you don't go too far on the cam.

    For normal everyday driving, a good carby is still effective.

    I can assure you a one dual barrel down draft doesn't go nearly as well as two DCOE's on my 17TS.

    Nothing looks more impressive than a gaggle of 'websters' hanging off any engine.

    And under the hood of an orange R17.

    Would like to know if the FAJS 40DCOE carbies are a good choice or just don't go there?

    Nobody has any doubt, but as post above demonstrate, you need to qualify the statement by mentioning what cams you've got and whether you're talking about traffic driving or racing.

    I think in your situation you would be better advised to go FI. You will spend more money on carbies and so on than going FI with a megasquirt or similar system.

    Not only that, but as Alan (or was it Col?) pointed out, if you change cams, you need to change the carby tune, and that can include venturis, which are not that easy to find nor cheap. With FI, all you need to do is change a map. If you don't change the cam, I don't think you're going to need side draughts.

    The Plan...Cam..Head work and so on, because we can. Not really interested in FI.

    I have a more or less stock cam from a 17TS/G except for some reason unknown to me when it was reground instead of 42,72,72,42 mine ended up as 42,72,72,52.

    Ray's helping me with this. I have a two engines, gearbox and other parts. An existing cam has been mentioned for Plan. We'll see what transpires.

    Thanks Bowie. There are a few businesses in Aus. They have helped with my original Weber 32 DIR 23 for parts when I rebuilt it

    The cam, the carbies, or the car? Or all three?
