    I tried fitting S50 3.2 evo bodies to mine and gave up. There are far too many issues to make it worthwhile. I honestly wouldn't bother.

    If you must have ITB's, then go for the Dbilas setup which are made to fit. You would also need the Dbilas cams to make the most of it.

    i wouldn't bother with throttle bodies or a supercharger! way to much cash yes you will get good power from a charger but is it really worth it, you would have trouble putting that power down on our crap roads and you trying to put 300ish brake through nearly 20yr old transmission which will only end 1 way!!! i would stick to the normal route and get the engine running sweet serviced and rolling road tuned, you would be surprised how much of a difference this could make. then go for a chip, filter and exhaust and get it on the rolling road again, if this aint enough then i would look into doing a engine swap, this can be expensive but if you have machenical knowledge then it can be cost affective to

    Lots of people talking about the hardware.

    No point buying and fittting it if you don't have access to a rolling road AND money for enough hours and good people to set it up.

    Don't forget Weber Alpha and VEMS management.

    However, at least in 4 cylinder world a lot of people are using bike carbs on Bogg Bros manifolds. Would be a nice sight on a straight 6. Plusfixed venturi always cause a drop in air speed when snapped open which is something variable venturi such as SU or bike carbs don't.

    Only problem with bike carbs there only for 4 pot engines so having on a 6 pot you would have to have custom linkage which could be expensive if you don't have a fabricating back round! They do sound the nuts tho on full chat! I think they would be fairly limited on a 2.5

    I would not expect them to be limited as people use 4 to feed Vauxhall Redtops and each cylinder on those is about 500cc so would easily be fine up to 3lt.
    If I remember rightly people are making more BHP out of a 2lt red top with 4 of these than a 325 puts out in standard trim.

    Linkage wise, I would expect you would buy 2 sets of 4 and mix them to use all of one set of four and the middle set of the other four.

    The red top is 1 of the most tuneable engines money can buy in fact by just taking the best part of the induction system off and replacing it with a power cap gains a good chunk of bhp, so I'm not surprised they benefit from bike carbs! Because carbs respond well on 1 engine doesn't mean they will on another. On a 2.0ltr Zetec they would only gain 15ish bhp on a standard lump. There designed for bikes that are on 1.1's say so that's 1 carb to 275cc would be good to see them on a 6 pot tho and proof is in the pudding if the gains would be worth it!!

    As someone already mentioned for a bolt-on setup you need to look at dbilas.

    The kit costs just over £2000 with claims of a 20bhp power hike, so not exactly the best bang for your buck.

    Still, they look very pretty, and think of the noise!

    Yes, a 1.1 engine that revs to around double the RPM, so it's throughput in CFM would be comparable to a cylinder twice as big running half the RPM.

    At the end of the day the carb doesn't care what it's connected to any more than an engine cares what feeds it mixture, it's all about just mixing fuel and air at around 14:1

    Why 14:1 ?
