2332 cc single carburettor will it work

[bang]

hey. i bought a 2332 motor with a fk10 cam in. it is for a bus and i like the original look. my thoughts was to put on a single carburator and modify original airfilter and tin and i want heat in the car.

any one run a single 48ida with that wild cam or do i have to step down on the cam.

or do i have to run 2.

The engine will run but it will idle terribly, get awful mileage, and make a lot less power.

[mr horsepower]

Just try it and tune it.
Then you know if it wil work.
Seen a lot single carb engines in autocros
Some ran like shit others verry smooth
Its al about the rigth tunning.

Gr henri.

[richie]

I know its not 100% comparable but I run a single throttle body in middle on my turbo engine with more cam than that and off boost it cruises around fine, getting a single carb tuned right will be more difficult but a big single barrel should be able to work with a plenum under it, is it worth the effort though?

cheers Richie

I've run a small Solex on a smaller cc engine with a bigger cam than that..........and it was HUGE fun!  Spits and snarls and lumps and farts, then for about 2000rpm all hell broke loose, hahaha!

A single 2BBL makes a big difference to both idle and driveability over a single, makes it almost nice, an engine that big could use a plenum like Ritchie said I rekn too, but the choice of carb to make tuning nice and easy and forgiving probably won't have a "W" at the start of the name (can I say H0ll3y without getting excommunicated?).

Centremounts with a decent cam don't have to be terrible at everything if you set it up right.

It will run very hot

A high vacuum at idle will make the engine easier to tune for idle.
Mileage might be lower but at a bare minimum.
Lott less power? O Yes!

Please give me a good reason why, because that sounds just like a guess.

[RhoadsVW]

OOps, I read again and I miss that it was a single 48.  Was thinking a smaller carb. 

[bang]

i want it to be as original and oldschool as possible. most likely to fit in a bus or my 71 carbrio. i was thinking single 48 idf or single ida.

know fat performance has used single cap on there dune engine might worth asking greg.

[fish]

You will do best with single 45 Dellorto, heated manifold and vaccuum dizzy

I don't see how a single two barrel is either original or old school?
In a bus application it will require a very short air filter, not good.
Comparing your engine to a Fat off road race engine is totally apples to oranges. Massively different application and they have class rules to adhere to.
The sensible choice would be a pair of 48 IDF's, but if we were sensible we would all be driving a Honda

Not as big engine, but some ideas to get from this maybe.

I remember tuning a WW Stromberg (small 2-BBL) on a VW in the late 70s here in Oz, and how many pics do you see of Bugsprays and Zenith carbs from "back in the day"?
That's old-school enough for me, we still even had B&W TV out here!  

My favourite carbs for this type of application are Holley 7448/4412, WW Stromberg, Carter BBD (as long as the piston chambers aren't stuffed), but my all-time favourite is the Bendix-Stromberg single barrel.
All of these carbs have excellent transition ccts that can supply heaps, cruise on mains economically, and have a power valve cct which means very simple part-throttle tuning. These carbs are all designed to happily run a big engine through small diameter long manifold runners with great throttle response and cruise manners, while pushing big un-aero lumps of cast iron (sound familiar?). Put a stock OEM 70s-type air cleaner assembly on it, complete with snorkel, and it would definitely have "stock looking" appearance to anyone but a VW person.

I'll warn you though, you won't get any street cred whatsoever at the next get-together, no matter how nicely it drives.........
 

PS: the cam will suit torquey highway cruising perfectly with stock rockers.

[Zach Gomulka]

Sure a Zenith, etc is "old school", but that doesn't mean all single two barrel carbs are. IDF/DRLA are far too new, and a single IDA was not a common sight.
I still say a 2.3L single carb with that large of a cam will not have good manners, will net bad mileage, and will leave a lot of power on the table compared to a set of duals. If you're ok with that, do it.

[Neil Davies]

How about gutting a stock carb and using it as a throttle body? Or even one step further, hide a turbo in the big oil bath air cleaner and blow through a single in the stock location?

[richie]

I have a single IDA manifold if you want to go that route Peter   All old school looking and chromed

A lot less cam and less compression, it will be possible.

If have a 2276cc Engine with Single Carb in my Oval, it works 

Here is the link:

and the upgrade with 39 PICT-3

Have 122hp at 4700rpm and 210Nm at 2600rpm torque

Yeah, 120 hp 200 Nm from a 2275 sgl. carb. (Modified 34 mm Solex) split duration split lift cam, but not even close to the FK10. Idles like a stock engine.

A sgl. 44IDF or 45 Dell could work OK with the right manifold and the right work to the end pieces.

[Jesse Wens]

are these modifications also possible on a 34PICT5 from a vanagon?
Got a high compression 1.9 in the makings.

[karl h]

is it possible to use a 36/40 solex from a Type 4 dual carb set as a single in the middle? i took a look, you have to modify the linkage, but the rest seems to work with an adapter to the maniflold. it even has a choke and the vacuum port

[Fastbrit]

For a while in the late 1980s, some of the PRA Pro Stock guys tried running a single four-barrel Holley on a fabricated manifold. It worked, but as soon as the big-bore IDAs became commonplace, they all went back to dual carbs.

[karl h]

i rember a plenum with twin 40 dells they claimed made more hp than IDAs

[modnrod]

Tunnel rams make more power than stacks, and a larger overall power as well.

Idle like crap, but that's 1/2 the appeal.

This is how my Engine look now:

 I have changed the exhaust from CSP supercomp to CSP Wasp Stage 1, the improvement in torque was about 8-10Nm the Sound of the engine with this exhaust is even more impressive.
The biggest improvemnt was the Change from 37 PICT-3 to 39 PCIT-3, better idle and great throttle response.

On Malec`s engine and mine you can see that this configuration works nice!

BTW: Congratulation Malec for your nice build!
