Title: Tune twin strombergs?
Post by: Marishka on April 02, 2015, 10:47:28 PM
Anyone know how to tune twin strombergs?
If so can i get a step by step please?
Also what do people think about twin strombergs vs holley 350
On a 186/192 with xu1 cam, flat tops,  etc
Or what would you recomend better than twin strombergs?

I bought an old Fb ute, love it already

Cheers marty

nice looking ute :) its a bitsa! FB bummer, EK grille and blinkers/bonnet chrome! I personally prefer the look of the EK front :)

I guess the twin strommys are a good period correct option for them, but certainly a 350 holley or weber is going to be easier to live with long term for tuning etc.

I guess it depends what you want, the motor will breath best with triple SU's or triple webers ;) but certainly the holley or weber is going to be the best for maintenance free use.

Yeah, looks good with the EK bits, wanted an EK but was hard enough finding the FB.
triple SU,s or webbers wont fit as the firewall protrudes either side,
The back of the motor sits in a slight recess so to speak.
Im thinking 350 holley will be the best option.
Ive got one and manifold but manifolds for blue or black head  :'(

the 34 ADM Weber  will give you good manifold vacuum at low rpm and torque and if your got a big cam it will help stop your engine  camming. the second barrel does not open till about 70% throttle when you  want power. they are very good on fuel too.  most car bone yards still have lots of ford  xe, xf  which the 34 ADM WEBER came out in . E-BAY is a good soure of the carby and rebuild kits and adaptor plates.

That sounds a better option than the holley johnxb351.
Will it fit onto a holley manifold or is there a special one ?
Cheers

here's an option Marty. 34 adm Weber (XE Falcon) on an Aussie Speed Manifold. this manifold is double drilled for Weber and Holley(http://C:\Users\Phil\Pictures\Gumtree). I'll be sticking this in my van soon.

Mine's a 12 port head but they do a 9 port for red motors.
The ute looks great by the way. FB's are as old as me :)

provided the strombergs are built correctly, they should be fairly easy to tune.

Make consistent adjustments in small increments to both carbys each time.

If you want a holley 350 manifold to suit a red motor, my grandad has a few, along with triple su manifold and carbys that came off a highly successful rally car my uncle use to pilot.

In reality, a single stromberg can be a weapon, so two can be awesome, you just need someone who can build and tune them.

When it comes to strombergs, go find your local HQ racers, as they know more about strombergs than most carby shops. We often get given a carby to build that has been done by 'reputable' carby shops. They more often than not have to go in the bin due to the simple modifications that have been made which render them useless.

My grandad is renowned among the race community across this fine nation as being a master of building these carbys to supremacy.

If you want one or two built, decide what sort of performance you are after and then feel free to let me know to organise having them built.

cheers,
Matte

Sounds good MaTTe,
How much to build 2?
Im looking for good throttle response and as good fuel economy as possible.
Im thinking the magic will be in jet selection and air mixture adjustment.
There,s not much more to them is there?
Would i be right?

yeah that's the issue with triples, the firewall needs massaging!

Hey Marty, apologies for the delay in response.

He usually builds race carbys for $250 which covers gaskets and materials along with jets etc and a little bit for his pocket and time. Building a street carb wouldn't be greatly different in terms of time or expenses, but can see if he can do a better price based on it being 2 carbys if you are interested.

The strombergs have an idle mixture screw, and a fixed jet or adjustable jet depending on desire. They are a very simple carb to tune, however all the performance setup is in the internal channel sizing.

Let me know what you think and we can organise it from there.

Cheers,
Matte
