what sort of aftermarket carbies would i be looking at for my stocko 1600? twins? what sort of hp change will i get?... what will it do to my fuel consumption?... all that jargon... any info or help would be appreciated
cheers

for a 1600 tp i would go for a set of cadrons with an exhaust upgrade to extractors not sure of hp gain but it go go better and as for fuel usage should not be excessive it will depend on your driving flatout a lot of fuel safe good fuel
good luck

40mm dellorto's or webers. fit smaller venturi's and adjust jetting to suit your engine. Add a quality exhaust system for more efficiency.
Kadrons. A second-hand set is cheap and cheerful and with a 009 distributor and a set of cheapie extractors, will make it more lively
baja burley ·
know where i can get all off this stuff without goin to the big boys and gettin ripped off???
VWCOOL ·
Maybe try a 'Wanted To Buy'...

i am thinking of a centre mount, single or double barrell 36-40mm progressive carb... i am plannig to do some mild offraoding... hows this for an option?? am i on the right track?? and how much would i be looking at for a carbie of this calibur??? and does anyone have a ballpark figure on horsepower gain for this carbie??
baja burley ·
what brand should i go for??

are you going to set up and jet this yourself or are you wanting a drive in drive out
Craig Torrens ·
with a stock motor you may get 3 or 4 more hp......if your lucky !

i sold my last complete one for 350, that was ready to fit
baja burley ·
a bolt up and drive away one would be nice but i can set it up if i have too....
really!?! - only 3-4 hp?? i thoght it would be more than that.
Craig Torrens ·
5-10% gain in power..............remember a 1600 isn't pumping out big HP !! With the Kadrons you will feel a lot more torque, so it will feel like it has added a lot more HP... Just make sure you upgrade the exhaust as well.
baja burley ·
so kadrons is the go if im gonna do some offroading??
baja burley ·
i have been looking at exausts to upgrade and have found a few decent ones but what is the difference between headers and extractors and which is better??
Stanley ·
Thunderbird extractors a pretty good and you can chose the style of muffler. Is it a baja?

even second hand, kadrons are not cheap anymore. 🥲
baja burley ·
yeh its a baja super in the making... see how it goes....
so extractors and headers are the same thing??
some fella has a pair of 32/36 webers for 100 bux, no manifolds are they worth it??
LIFE IN THE LOW LANE ·
progressive linkage 32/36 weber would work well. All you need to get is the right manifold.
pete wood ·
I had a thought, I could be dreaming, but what about a drawthrough turbo setup. Probably cost about the same cash as a kadrons, manifolds and linkage and would make for a bigger torque/power increase. You'd have to be careful about overboosting it, but premium unleaded would help.
What do you think stanley?

Thought centre mounts were the go for baja's and buggies??

great idea...there is precedence somewhere for that...🤪
Also just realised i replied to the wrong post. Thats what happens when you're trying to hide your internet use at work.
baja burley ·
i havn't even got my licence yet so a turbo is off the cards (stupid P plate laws)...
does anyone know the specific manifolds i need and pricing?
and are the webers worth it???
pete wood ·
where abouts are you? If you are in NSW, your motor can't be modded on P plates anyway.
baja burley ·
im in QLD
matberry ·
The progressives will work but only as a single, unless you do some interesting engineering.🤪
will the stock manifold work if its just a centremount??
pete wood ·
Yes, you use the stock end manifolds and the centre mount manifold then goes straight into them. BTW, a word of warning, the EMPI brand has had negative things said about the quality of the it's weber reproductions. If you can, I think you might find a rebuilt italian or spanish 2nd handie might be better than a brand new chinese EMPI. I may be wrong on this, but everything I'm hearing from experienced carb users in the states says EMPI stuff is not great. This is added to the colourful reputation the progressive has on VWs. I've personally heard great things about the use of weber progressives on subarus, old peugeots and escorts, so I can't see why VWs engines would be any different, but there you go.
Your other alternative is to try and find a set of cheap 36idfs like I did. They were on Alfa 33s. These are great little carbs and would be well suited for an offroad 1600.

I didn't realise you were asking about an off-roader. You will need to look at extending float bowl vents to prevent them spilling fuel into the throats of the carbys in rough conditions

just gotta know where to look
i picked up a set in perfect nick for $250 of ebay a few weeks back that only missing the T peice which i got for $5 from enzed
then about 2 weeks later another set sold for $270 in the same condition
theres a bit more work involved than just chucking a turbo on but yeah leave that one for further down the track
single carbs work well if u have good manifold heat but twins will give u better results but steer clear of the weber progressives if u can they work well but take a hell of alot of tweaking to get right
pete wood ·
fair enough. I stand corrected. Still, my $100 36IDFs are looking good. 😉
baja burley ·
so the progressives arnt as good as the non-progressives? i just read somewhere that progressives get better fuel economy and more drivability by only sacrificing a litlle bit of perfromance... what are idf's???? i also read that twins are no good for offroad but they didnt give reasons why. and this is why i went off em.. is this right???
pete wood ·
Have a look round the web. Do some research on Weber IDF and IDA carbs. The IDAs are essentially a racing carb, but even still. And lots of offroad cars use twins, filters can be pesky but it's nowhere near impossible. Also, it is possible to run a single IDF center mounted. This is a common baja bug setup in the states.
matberry ·
I went single DRLA 45 on a 2074cc in about '86.....never again; duals, and make a remote air filter arrangement in clean air or single TB EFI, and also remote mount filter.

Pete, i think they were one-offs
the usual going rate for a set of K-dogs is around the $400 mark
burley the progressives work and plenty of ppl use them they can just be a right royal prick to setup and jet
and dont give the benefit as good as a single IDF or DCNF does
oh yeah keep clear of old holleys tho if u come across one they were shockers and a few have been popping up on ebay lately
2 settings - rough idle with ice or flat bickey
i didnt even bother selling one i had it went straight in the bin altho i wish now i kept the manifold

Hey BugSprays are not bad, I could never understand all the hate for them I have had little to no touble with mine all these people poo pooing them and yet I made 50rwhp on a 1641 with extractors and cleaned up heads......
Compaired to the twin 40 dells I now have it was a shit load easier to get working correctly and don't talk to me about rough idel with duals lol
It is however important that they are set up correctly as decribed in the old how to hod rod your VW engine book, useing a plenum manifold is a big no no they need little to no plenum it is even stated that you should block the equaliser gap on the end castings which I did, they run better with a vac advance dizzy but a 009 will work ok too
When I first got the carb it had a plenum manifold and it run like a dog I was told by a supposed expert that "Its just the way these farking carbs are there shit throw it in the bin and get a webber."
After doing as the book said I coudlen't be more happy with how it runs now.
baja burley ·
righto. great info guys!! so the new idea is twin weber 36 idf's on a NON-PLENUM manifold with pod filters. what sort of money am i looking at now??
VWCOOL ·
'Non Plenum' really only refers to centre-mount carbies... 'twin' means duals; one per side of the engine
Not sure how much money you have to play with but get a set of Kadrons, fit float bowl breathers and and see how you go... Cheaper and easier than dual Webers
pete wood ·
why don't you sell him one of your sets. 😁
baja burley ·
little out of my budget i think guys but somthin of the like would be good!
