The prefix number on the DCOE is the diameter of the throttle plate (the throttle bore) in mm; DC means "doppio corpo" (double throat); O means "orizzontale (horizontal); E means it is a die cast carburetor; and the number or number and letter suffix is the variation type. Except there seems to be several variations to most variation suffixes.

what does dcoe stand for?im not to sure what the d stands for,but i'm pretty sure the coe stands for competion horizontal evolution.if this doesn't make sense,try these words in italian,which is competitione orizontale evolutione.so,can anyone guess at the d.what's italian for carburettor?

These so called performance shop pepole who sold you the wrong bits need a visit. Go back and tell them they sold you the wrong bits if they still refuse you a refund tell them that they have big windows and therefore cant afford to scam people like you. DONT TAKE SH1T FROM ARSEHOLES LIKE THAT. If they sold you the wrong bits they have to take them back.
TAKE #### FROM NO ONE!!!

YEah I looked at the redline web page
( "http://www.redlineauto.com.au/manifold.htm" )
and they only list stuff for webbers.
will try and find a local stockist in perth and give them a call though. i recall now on the back of a street machine mag an ad for redline with a twin su manifold advertised with a perth number. have to go and buy one I guess now.
edit :
ps what does DCOE mean??

i think Lynx come under redline now and i think they do still make a manifold for them. pretty sure redline would make one. if not searcht he papers for A series GX stuff and hope you stumble accross one

I have done a bit more research and I cant find any manifolds for twin SUs for a 1200 round port head. Lots for webbers, single,twin, down/side draft, but nothing for side draft SUs.

I bought a unit from a reputable performace shop here in Perth, Welshpool to be exact, and they didnt sell me the right one. It doesent fit my head, or atleast it doesent fit one that I have on the shelf spare, so i guess its for a L series. I will put up a photo of it when I get home.
They assured me that it was the right one, and that they wouldnt refund it for me cause it was old stock, and it was the right one, so it wouldnt be a prob. i guess that I shoulve smelt a rat when they say that. Pisses me off no end when I get crap advice from supposedly the best performace shop in perth. These weere the same giys that told me that a $500 dizzy will fit a vacum advance problem with twin SUs that was discussed in an old thread. I guess they only like v8s so everything else is just crap. sad aint it. I love a bent 8 as much as the next man, but my datto is a bit more cost effective and so is the weapon of choice.

The sock filters thatyou metion, I assume are really only a fine filter suitable for racing or bitumin use only. I expect to use my car on the gravel a bit about 15-20% fo the time. (I have frinends in the country)
I guess the best way is to have lynx or unifilters fitted, with washable foam type.
The only trouble with lynx manifolds is that they were bought out a while ago I think, and they dont produce under that name anymore. I use a lynx adaptor to bolt my webber to the standard 1200 manifold.

I guess that whilst the trumpets will probally allow better airflow, with my expoected driving conditions, I will eventually kill my engine sooner rather than later. I think they willbe reserved for photos shoots only.

u can get unifilter trumpets with sock filters for su's, i wonder whether they are any good, does the filter sop the trumpet effect?

hi, i had twin SUs on my last car, an A15 apparently the guy i bought them off and a few mechanics said they were on a 'lynx' manifold. dunno if that means anything to anyone.

Hey there,
Just in relation to the trumpets- keep them on if you can. There is some evidence that they actually help speed up the intake air and help with higher rpm hp.
As far as manifolds go for the SU's, check the redline catalaogue- I am sure they do one for a SU's onto a 1600...

Cheers
