This is a sneak peek of the new cable linkage system that we have been working to complete for quite a while now.. Available (SOON!) for carburetors or our "Extrudabody" EFI throttle bodies.

These pics are of the first fitment of the new arrangement onto a pair of EMPI HPMX carbs on our display fixture. There are several changes necessary, but for a first mock up and fitment the system worked better than we'd imagine. The final kit will have all anodized parts, full hardware and etc included along with an installation DVD produced by yours truly.

There have been efforts by others to complete a system like this,(some with great results) but to date nothing has been universally applicable or commercially available using this method of actuation and synchronization. There has also not been an attempt made to replace the OEM throttle cable all the way to the throttle pedal.

The difference in this system is that the permanently lubricated sheathed cables will replace the ENTIRE throttle cable arrangement all the way to the pedal. This will be accomplished with a system thats comprised of one primary cable from the pedal to an intermediate link housing that will tie both cables together. The high quality, multi-role intermediate link will also have the adjustment and return spring for the arrangement in a combined unit.

The intermediate link will reside above the transaxle and will triple as a quick disconnection point should the service of the engine/ carbs need to be carried out. This intermediate link is one bad ass, yet VERY SIMPLE part!

The secondary cable couples to the primary cable via the intermediate link then travels around a billet cam on the "lead" carburetor/ throttle body. This cable then continues through another sheathed cable to the "slave" throttle body/ Carburetor.

The benefits of the cable system are numerous.. I personally like the lightweight yet very robust construction coupled to the fact that it omits the factory throttle cable and replaces it all with new much stronger parts. It's also easy to custom tailor pedal feel and throttle actuation with adjustments made to the cams and cable tensions.

I have been "over" Hex bar linkage systems and their inherent issues for years.. Bellcrank systems have proven to be expensive and can be problematic with engines that have greater expansion levels as their synchronization is effected as the engine "grows". With this system is doesn't matter how much the engine expands the cables retain their tension.

This is the smoothest and most accurate means of carburetor actuation I have experienced to date.
Here are some features:
-Universally applicable for all Weber IDF/ EMPI HPMX and Dellorto DRLA applications for the Type 1, Type 4 or Porsche 356 engine!! The same kit can fit all these different engines! The same kit can also fir a Type 3 or Type 4 engine using these carburetors with the stock pancake cooling system.

-With very slight changes this same kit can actuate a set of 48 IDAs on any of the above engines as well.

-High quality billet throttle cams allow for easy adjustment of the system for various pedal arrangements

-The entire stock throttle cable is removed and replaced with the "accu-link" components

-The intermediate link allows for ease of adjustment, a quick disconnection point, coupling of the primary and secondary cables and a redundant throttle return spring all in one self contained, snap together housing.

- The sheathed cables are adjustable in 7 different locations for ease of tuning the system to the vehicle, driver and carburetors.

-Engine width and expansion will not alter carburetor/ throttle body actuation or synchronization at all.

- Very light carb return springs are able to be used due to the ease of actuation and the slippery sheathed cables. This allows for a nice pedal feel without giving up snappy throttle action

-Carburetor throttle shaft bearings/ bushings will see reduced loads and will live longer.

- No mechanical parts to wear out like ball sockets and heim joints/ spherical bearings. When the cables begin to stretch the adjustment can be made to them in 7 different places throught the arrangement. Spare cables can be sold for pennies to keep in the glove box..

- No heavy mechanical linkages to attach to the throttle shafts and transmit harmonics to the throttle shafts, thus chattering the accelerator pumps making them dribble fuel down the intakes.. This is a tuning issue that many people fight and do not even realize it.

- Its different! As different as a DTM cooling system or a big bore Type 4!

-Its also going to be very cost effective with all parts (except the throttle intermediate link) made in the USA including the cables, billet throttle cams and etc. The throttle intermediate link is made in Germany and has been proven in the 24 hours of Le Man as recently as this past June :-)

And as of today the Patent pending processes have been initiated!

That stainless braid looks so badass and gangster as well.

It screams business and function.


Wait the entire actual steel internal cable is coated with something as well?

So this pretty much beats a terry cable up as well. I was not terribly impressed with my terry cable, it actually is not as slippery as a gemo with lube was until I broke the gemo

My theory for that was the lack of plastic sheathing and the little bit of play in the cable allows it to touch the inside of the cable tube.

I want one.

I am still puzzling over my hex bar set up.

John

Any ideas on cost yet? I would seriously consider it, if its cost effective.

These are non compressable sheaths.. The cable is very slick and coated.

The throttle action is very smooth and light even with finger actuation..

I first was exposed to this set up with our Boxster throttle bodies and an adaptation to the aircooled set up was a natural evolution :-)
Cost?? Nope, no idea yet- I don't worry about cost until it works.

Believe it or not it'll be cost effective, especially because this same set up can be used for Type 1, Type 4 and 356 engines in any car as a single arrangement.. That means higher volumes and standardized parts.

Seems way too simple.

This totally rules.

Sounds like the carb guys have a solution that ends any linkage issues finally.

I am probably going to move to this once the time comes as well if I don't end up with some standalone e-gas solution.

Speaking of Jake, any word on your standalone e-gas drive by wire stuff for type IV's?

Megasquirt is only slightly better than l-jet or any other system.

The ECU is in my 912E now... I need to download a new software package before I test it further as now they've tweaked the adaptive resolution and have added the ability to tune via bluetooth.

I'll be using it along with this linkage and the extrudabody throttle bodies in our double cab..

Great work Jake! This is long overdue.

this looks great, Jake! be sure and let us know when they are available!

I like it. Beats the heck out of anything I've seen. The only question I have is where is the idle stop?

Throttle idle stop is on the opposite side of the carburetor....

looks like my dirtbike set-up ! cool !

I might wait to convert my 2.0 from single Weber progressive until this kit is available.

Hear that, Jake? No pressure, but the sooner you get this kit available, the sooner another single-carb gets demolished.

Can **I** demolish the single carb??

LOL.. I got a new Saiga 12 and I am dying for a to end the life of a progressive!

Why must you continue to taunt me with products I need... err, want?

To stimulate the economy!

Could this work on other throttle body setups as well? TWM for example?

-Josh2

With mods I am sure it could...
The TWMs have really gone down hill lately though.

Jake :

We expect nothing but the " Best" from you. And you have delivered

again. Next thing you will do is a billet type 4 ,that you personally will carve

out of a chunk of Alum. Just keep getting better. Dave

Nice to know. Mine are sitting in a box on a shelf, and have been there for quite a few years now (4? 5?). Hopefully in a few more they'll have aged enough to deserve being installed in the car...

-Josh2

Nope.. No one would be able to afford it....

Its not just me, I have a group of other hard chargers that help me make all this happen!

the only issue I see is where the main joins the carb (the one with two cables attached) it seems a s though there will be a wear problem as the cable rubs the end of the adjuster screw. Maybe a flared end or a way to rotate the assembly where it bolts to the carb.

My $.02 but it looks good! hell with the right fixture it may even work on a 6!

Josh

Actually thats only ONE cable! It has a barrel nut that tightens to the cable and locks into the cam.

What you see here is one section of constant cable. This will connect from the intermediate coupling all the way to the termination point on the slave carburetor without interruption..

No splices anywhere except at the intermediate coupling, which is designed for that task..

Jake this is really cool. Now that I have seen it, I kind of can't believe that I have not seen it before. Inline and V engines with multiple carbs have been using cable systems for years.

Yep!!!
A few people have made their own system that functions similarly; with cables.. Their was done a tad different, but still worked well.

But this is the first commercially available arrangement :-)

Now I wonder how long it'll be before the Chinese copy it???

Long anough for oh.... say...... a bus with a 6 in it ?? Just thinking out loud

This will fit a six also...

So does this mean the Extrudabody ITBs are of good quality? I've been looking at some for another project (mainly because of price), but hadn't heard too many reviews.

We've been working on several projects with extrudabody...
I like them a lot.

That's awesome! Thanks for the heads up.

This looks very cool.

I'm tired of my Hexbar.

The market needs a product like this. None of the linkages currently available come without compromises.

I hope you can make it work Jake. I'll sure as hell buy one.

it's already working.. Just gotta optimize it.

That is a slick looking setup! I've got a couple of dune buggy friends that I'm going to pass this info on to. They'll probably be quite interested.

Wow! Everything seems so simple once you actually see it! It is being the first one to see it in your head that's the hard part!

Looks great!

They are already working on it.

The copies will be made of lead, and give you aids from using them so I would not worry too much. The chinese have the reverse midas touch when it comes to automotive.

I thought at one point i'd be safe with cast iron, no they fuck that up too. Lesson learned. I just dropped 1100$ on new turbo exhaust hardware because zang ghong foundry LTD uses recycled sewer caps or pig iron to pour into their crappy molds that are not even scaled right.

Maybe, but never under estimate the Chinese, 40years ago "made in Japan" meant crap cars....this is only the beginning.

The best ideas are always the simplest. Go Jake. I love the idea of one cable, running to one, then across to the other - sooo little to go wrong. (on the rhs linkage, no need for the second cable attachment though? - to neaten it up even more?)

Jake,

Will this work on carbs that one pulls/pushes from front and the other pulls/pushes from the back?
I am using a bellcrank setup at the moment attached at middle case bolt.

Thanks for an answer
Ken

For this to work both carbs will have to rotate in the same direction.. Thats pretty much the only requirement.

how simple would it be to make it so they didn't have to rotate the same direction?


Would something like what I have diagrammed out be possible?

Anything is possible..A version like this would have to be created by the user, from the pieces we'd provide.

We might make up a DIY kit of just parts so people could make their own custom arrangement.

Look for some idea of pricing next week, then I'll need to hear from those wanting to buy one before we go further.. If it won't sell in good volumes there isn't any use to make mass runs of parts.

I freakin" can't wait to ditch the hex bar on our F-Prod car! We'll have to figure out a way to operate it with the Morse cable that we currently use to actuate the hex bar.
Nice work guys!

This is similar to what I've been carrying around in my head for awhile. Glad to see a real live version.

I HATE CROSSBAR LINKAGES, and I'm ready for more people to use something else.

I now have a tentative price... 159.00 per kit..
This is in high gear, I haven't had a response to something this positive in quite some time!

Do you also anticipate selling carb kits that include this in place of a standard linkage? (Rather than buying a carb kit, discarding the linkage, and buying this in addition)

This will be the only linkage we will be offering once it's perfected

Let me be the first to point out that this new system appears MUCH LIGHTER than the typical cross bar set up.

I only wish I hadn't just bought a new linkage a couple months ago...

It is light!!Very light!
Otherwise Len would never let me use it on the FP car. Hell he wouldn't let me put more than one coat of clear coat on the paint job! He said it would weigh too much!!
Even my video camera had to go on a diet to allow it to be installed into the car!
