Brave, also minted back in the day as Twin 40/45 where the thing to have. Night rally regs stated only two chokes, single cam and 4 cylinders. So
splitting them meant you could line them up perfectly to two ports each, although I used a single 45 on a swan neck manifold as only the real money
chaps bought two and butchered them.
Happy days back in the 80s.

One of the reasons I am partially deaf, two Weber throats behind an ali plate over the speedo hole and a 970S turning 7000 rpm and wearing an open
face helmet and no ear protection. Oh! the good old days.

Eventually Weber brought out a single choke version of the DCOE especially for use as pair on the A series.

In the UK Mini racers were left choking on the dust left by 998 Imps before they disappeared off into the distance.

Yup, I remember these, had them on our AutoX Mini about 37 years ago!!! 850cc Mini screaming up to around 8,000rpm & as said only thing between
you & the trumpets was a bit of thin ali, perhaps thats why I am also slightly deaf!
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

My brother a 45 DCOE (just a single one) on his 1380 mini with a simple alloy box fitted into the bulkhead. He also had straight cut box and straight
cut drop gears. We drove it from Plymouth to Silverstone for the Mini 25th Anniversary celebrations, and both of us had ringing ears for days after.
Young and foolish...

Never heard of this one ..What was its desgnation?..And did Brirish Leyland Special Tuning ever use it? I remember they experimented with Lucas
mechanical injection albeit on a 8 port head though.
Incidentaly,why wasnt a single 45DCOE just as effective?

taking the topic away from Minis, I seem to recall something similar being done for the B series engines (for MGB) but without chopping the carbs -
again one choke from each carb feeding the siamesed inlet ports .... or did I dream that up?
picture anyone?

with a 45 dcoe the two chokes are too close togethor. a split 40 dcoe gives you the exact distance to make a straight fuel inlet for both ports
makes a few bhp difference and can seperate the winners from the losers

Had something to do with charge robbing which made the outer cylinders run rich and the inners weak

It's not just you old boys that know about split dcoes! Anyone who's read Vizard's A series book should know about them too.
Just as with using a 48 IDA for full silliness, like this:

To be fair Vizards book only has 1 small section I could find regarding split webers (I checked this morning) and reckons they weren't really
any advantage in the end.
It's only for getting a straight shot down at the ports apparently.

Ah, I remembered it being more than that, but my copy's buried in the garage somewhere.

I remember in the dim and distant passed fitting twin Amal monobloc bike carbs to my mini with one float chamber cut off and being fed from the float
chamber of the other carb.
Wish I had a camera in those days
Denis.
Where did that go?
