    Rolling road day at Stealth, I`ll have to get mine finished and driven down, do you have to book a place Gary? (This is assuming the G hasn`t grenaded beforehand).

    Velly's organising the day Keith, think there's about 24 names on the list already, but you know what it's like ;)

    He's got a thread running in club gti events section.

    if yours is normally aspirated then i reckon my torque figures should be on par or better than yours or any other (NA) 8v on the forum.

    even without the nitrous.




    (mind you, if the engine isn't finished by then i'll just have to bring my pushbike and pedal hard!

    why pay for a 160bhp carb setup, when you could have a 155-160bhp k-jet setup for 60 ish?

    [8-}]

    GVK can't wait to see some results form the carb engines

    Because they are 190bhp well set up not 160.

    I use 40's on my 9a for low down power, In sprints i only tend to use 1st 2nd 3rd gears.

    Oh yes - that is why I am collecting the parts to rebuild my 16v lump and use carbs!

    There's a serious amount of rubbish talked about carbs. :lol:

    They're not the ultimate answer to tuning. The sound doesn't
    make up for poor economy. But they do offer a few advantages.

    Answers to a couple of the common myths:

    1. "You need 45s for a 2.0."/"They give poor fuel economy." Of course
    you're going to get poor fuel economy if you fit massive chokes trying to
    chase the peak power figures. A lot of tuners seem to play along with this
    "bigger is better" myth, probably because people are impressed by the
    big power figure and for some reason seem happy enough to accept
    20mpg from an engine which is probably slower than a better tuned
    setup with a lower peak power figure.

    2. "They're expensive to set up." Mine cost me 40+VAT for the setup.
    That's cheaper than the essential Stealth setup and WUR mod for K-Jet
    isn't it? As far as going out of tune, how does a choke or a jet go out of
    tune? There aren't actually many parts that can go out of balance.

    Here's a plot for a 9A with Dellorto 40s (32mm chokes), KR cams
    (otherwise standard), cast VW exhaust manifold and Jetex 2.25" exhaust:

    <a href="http://img.photobucket.com/albums/v521/gs3333/rr.jpg" target="_blank">Click...
    </a>

    I've not got an axe to grind here just because I've got carbs on my own
    engine, I'm just trying to add a more balanced view to the discussion. Part
    of the reason I fitted them to my car was that I wanted to try and figure
    out the truth behind some of these myths. Would I fit carbs if I built it all
    over again? No, I'd fit DIY throttle bodies and MegaSquirt. But I think twin
    sidedraughts definitely offer a few advantages over K-Jet.

    It's bad setups and people talking bullsh[/i]it that means it's difficult to
    have a proper discussion about what the advantages and disadvantages
    of carbs really are.

    Good post Greg, much more reasonable than "they sound good" full stop.

    I still would like to see though, a similar mechanically specced engine to mine, but on well set up carbs on the same rollers on the same day, to see what's so good about them, or not.
