    Does the engine cover close with those carbs?

    Why the 3 carb set up? In the old days the only reason for a multi carb set up was because they were single barrelled.

    My 66 GTO came with 3 duces from the factory (RPs)...they needed the fuel.

    This is not meant to be a criticism or anything, but I spoke to someone once about the same setup for Christine and he said that while it improves the power, it's not happy until it's at full or nearly full throttle.

    That may not be important to you, but a lot of people want a car that's civilized in town and sporty on the straightaways. If that's the case for you then you may need to think about how it will drive.

    Of course I could be completely wrong as I never drove a D with that setup so this is more of a 'maybe this could potentially be an issue' type thing.

    I'm assuming only one set of barrels will be set up as primaries. The other four barrels will be set up as secondaries to open under load/acceleration/full throttle. Its a pretty common setup on muscle cars. No engine could run all 6 barrels all the time. You would constantly flood the engine.

    Looking at what can be seem of the tubes and not seeing a choke mechanism on the center set, I can see them as running in pairs. I've seen it before -- They just jet them all down while matching...similar to dual quad setups (never liked them much...).
    The goat has them set up as you said.

    I'm far from an expert, but it seems the weber will give you more power. If that's what you're looking for, I'd say go for it.

    I'm guessing that the racing engine has single-plane intake manifolds. Single-plane manifolds (e.g. Volvo A-Series) are happier at higher RPMs. A manifold with one plane per cylinder bank (e.g. mine) would behave better at lower RPMs.

    Thanx. I have a two triple IDA's of a 911 in mind already. Dono yet. Will explain soon.

    Right about IDA's not IDF's

    Well said Nick

    Ok. After a long search I am between the 40 IDA's (racing) and the 44/48 IDF's

    The difference is that the IDA's are not really the street type carbs as they are happy with full throttle (and they kick some booty at that) plus they are 2X-3X more expensive used than the IDF's new prices.

    Now the IDF's have a better progression in power, but do not "climax" as high as the IDA's. So they are stronger at the low RPM's but weaker at the highs.
    Should I want my D to take place at races, the IDA's are my choice. But for regular driving with some salt and pepper, IDF's is the way to go.

    A few specialists even make slight mods to let the IDF's reach a better peak but not as high as the IDA's. Still a small upgrade... With the downside loosing some better progression.


    I will see what that racing Alpine engine is coming in with and update you folks with news. For now the 42IDA are impossible to find! Only used 2x triple 40s are on sale around the world off 911's.
    Then I need to get a PRV matching intake manifold for them. Any links or contacts to that?

    GREAT find BABIS! Thank you!~

    BTW yes those are the ones I have in mind. Those go for 1200 a set. But does the Porsche intake manifold fit the PRV? That is my problem / question.
