Twin Webbers on a 1.4 VW?
Errr ok.
Probably better with a single decent size Webber on that engine. A lot less hassle to set up and cheaper.

yea cheers for that nobhead ill let him know
Phil W said:Yeah think the General jist (correct me if i'm wrong) would be to replace the standard carb with a Webber one, you would still need the Inlet etc though iirc.
I've got a webber carb sat in my shed, been there for 3 years now
Would it fit a polo, if so i might be able to sell it for you phillip ! I really know nothing about this hence why asking here
The carb would fit, but you would need to purcahse your own Inlet for it to mate it up!
Don't know what its worth, ill do some research, won't want much for it, beer tokens and postage paid for will do me
/edit infact i could send it up to Camberley with my Uncle when he next visits (at least once a month)

What webber though? Downdraught, sidedraught, 40 or 45 DCOE?
Wow, some typically OcUK comments in this thread....
Twin 40 DCOE Webers are ideally suited to a revvy 1.4 like the Polo, but he'll need linkages and an inlet manifold to match. It's also wise to fit an uprated pum, you can often find these cheap on ebay, a Facet should do the job if you can find a cheap one.
Of course, if he is just on about swapping the standerd (Pierburg?) carb for a Weber replacement then it may even be able to use the same manifold, they often do.

Bare in mind it will need to be correctly jetted. To replace all the jets is in the region of £100 (for new jets anyway). It will also need to correctly setup on a rolling road for best results.
Might be worth buying a service kit as well around £30-£40 to renew all the gaskets and springs.
You can buy a newly refurbished Carb jetted to your spec for around £100-£200.
I have a pair of DHLA 40's to go on my midget, cost me £250 jetted to my spec.

Cheers for the advice mate, It may only be a polo but its sitting on coilovers and boy does it go round corners just needs a little more "umph" he decatted it today too so now its obscenely loud
I mentioned to him about the inlet and it matching up and he said hes getting a kit so everything matches up ! Hes a trainee mechanic so he knows a fair bit !
Phil if you could dig it out and let me know what it is, i mentioned it to him tonight and he seems very intrested !
Cheers folks

no need to be like that.

If he realy wants twin DCOE's (rather than a single twin choke weber) then one carb is no good to you, you really need to find a matched pair because there are numerous different variants of the DCOE made over the years.

To be honest it is going to cost him a shed load of money to fit twins and will need to be set up carefully. Even then I can't really see much more than a 5-10 BHP gain on a 1.4 8v, although the throttle response will be grately improved. The conversion would also benefit from a free flow exhaust system of some kind. He will also probably see a noticeable drop in fuel economy.
Getting it through an MOT will also become interesting as twin carbs are notorious for going out of synch. Then of course you have the insurance and all that hassle.
Having had twin webbers in the past on an Alfa I became quite familiar with setting them up and all the problems encountered. A good single carb would be an excellent alternative if your mate is not ready for big bills and loads of time.

when i had my first car (1.4 lx mk4 escort) i took it into my mums friends garage to have the tappets sorted, it came back with a twin webber attached to it.
It makes quite a difference to the car, not to mention i was having to fill up twice as often

Twin DCOE's can give you more then 5-10BHP, and Ive had many a set on my cars in the past -
Just two of them
RS2000 Mk1 - running twin Webber DCOE 40's with K+N filters
Rally Preped HSR Chevetter - Running twin DCOE 48's with ram pipes
and many of my older Mini's had a single Webber 40 DCOE with the batterybox conversion.
All of them needed rolling road tuning about once every 6 months to keep perfectly balanced and set up. You need to find somebody wise to actually balancing them both (thats the hard part usually done by using a stethascope (SP) in the past. Many rolling roads these days have got used to ECU Management so you will need to find a rolling road that does have Webber experience (usually older rally cars)...
The one thing you cant beat is the noise of twin webbers sucking - sounds better then jenna jameson!!
