Hi Guys

Whats a good replacement carb for a 1650cc, mild cam and some head work. Its a twin port and so far I have only installed manifold on each head. I haven't got the center bit.

Wondering if there is a center bit that maybe has mount that would suit a twin weber downdraft or similar, or should I just go to Classic VW and get a new Empi carb, if so which one.

Thanks Trev

No to Empi

Get an original Pict 34 rebuilt

Personally - i would either go Pict or dual dellorto's (or Webers)
I dont like jetting single dual throat non progressive carbs

Again - personally, if i had to, i prefer a progressive 32/36 to single IDf/DRLAs

My 2c would be go dual's.... make some use of the cam and headwork !!!

Ideally Webers/Dells, but even Kadrons would be a step up. No personal experience with Empi carbs.

My old 1640 with a mild cam, standard heads and a set of Kads was a ton of fun compared to a 1600 stocker.

I didnt really want to go duals, this is my daughters car and I want to tune and forget. I have had a fair bit of experience with multiple cars, from triple SU's and Triple webers to dual 1150's on a tunnel ram. No matter how good the linkages where there was always balance issues after a few weeks. Is this still the case.

You will have no balance issues once set if you use good quality linkage (berg).

I have tried the hex bar set up with my hillclimber and had to rebalance after evey event,

Have now used berg linkage on weber 48ida,s and never touch the balance unless removing engine.

Top quality gear = top quality results.

Cheers Col

ps ,I would go single 34 pict 3 for my daughter.


Sides - January 8th, 2010 at 10:12 AM

Uh huh - fair enuff.

Well if you want to stay single, then I'd second Bizarre's saying either stick with the 34 pict (rejetted possibly) or a progressive Weber.

Or for some more input, I agree on the Berg linkage, purrfect, otherwise with the mods you have, there is a single 40 or 42 DCN Weber or a progressive 32/36 DGAV Weber or even a single 40, 44 or 48 IDF or DRLA, Weber/Dellorto respectively. All of these work to differing degrees of performance, cost and fuel economy, if you know how to set them up.

Hi Guys

What do you think of this one on Fleabay

make sure you can find a manifold. thats the hard part.


jsheppard64 - January 8th, 2010 at 06:00 PM

Hi
I have 32/36 on 1681 something (88 barrels) with a mild-street cam and big valve head.
scat manifold on 32/36
the engine was ok with the 32/36 once jetted right and manifold heater pipe.
and if i fitted the electric choke i wouldn't have to adjust the idle mixture between winter and summer.

oh and have to say my 32/36 gets lean when i turn left too hard. could just be my float setting tho.

cheers

Don't bother unless you have a manifold or know where there is one.


cb john - January 8th, 2010 at 09:12 PM

to make a manifold is an easy part...tune it right, thats the hard part...:lol:

make sure it's a DFEV (E is for electric choke, A for water) which is a mirror image of DGV which are common around specially on ebay
DGV are throttle turns another way

I have a DGV 5A and made linkages for it. I don't run choke because i have it idle a bit high because the oil light comes up when hot and i need a new oil pump

say if you have a bit of money.. buy them as a kit


Joel - January 9th, 2010 at 07:48 AM

if u got low oil press at idle when its hot oil pump is a bandaid fix,
your bottom end aint what she used to be

re the progessives, those things are only good for target practice
they work ok if there jetted 100% correctly but most people give up before they acheive that sense of euphoria with them

and even then the gains over stock arent worth all the heart ache

as matberry said a single syncronis barrel weber like DCN/F or IDF give heaps better gains and are a breeze to jet and set


clinker42 - January 9th, 2010 at 08:01 AM

Ok
So if I go IDF, would you stick on a 40, maybe a 44 would be a little too big.

Trev


colonel mustard - January 9th, 2010 at 08:41 AM

44 would be overkill.

You can buy single 40 kits on most vw part sites, make sure you get a linkage..

I have a single 40 dcnf, waiting to go in my car. Once I work ot a linkage setup, it will be fab!


matberry - January 9th, 2010 at 09:13 AM

I recently put a 44 IDF on a 1915 with a propriety manifold, took off a 40 DCN with home made looking manifold, and the engine came alive. I dont think a 44 is too big for a mild 1600, you can always put in smaller vents if need be.
The biggest pain with any single is the throttle linkage, and the US stuff has a nice little linkage that puts the throttle back to where it should be.

I do prefer duals any day though.
