Duel Carb Linkage, Carb Linkage Options

[dirk2056]

What linkage works best with duel IDF Weber, EMPI, you pick. (not easy but stays in adjustment). I have tried a few but had little success them staying in adjustment over time and ease to install. Please provide pictures if you can.

CSP Hex-Bar setups suck

Best Tangerine Racing

2nd place CSP Bellcrank

I use both. Either one will get rid of carb sync problems associated with center pull linkages.

I have several hex bar setups on the shelf, should be in the scrap pile as I could never get them dialed in. I fabricated a simple bell crank deal with basically some crap laying around, some all thread and some new ends from Pegasus. Works great for 3 years running now. I wasn't crazy with the push/pull setup

Another vote for Tangerine cables. I gave up on the rod type system (that came with my EFI kit) even before getting the car on the road.

I put the CSP bellcrank on my car with Empi Weber copies and never had it tune so easy. I could never get the hexbar linkage to sync at all rpms or stay in sink for any period of time. My car now runs better than ever. The cable systems look like they would be great too but no experience with them.

Looks like the sync link from LN doesn’t work for the 914…
I’m just getting my car on the road for the first time. Looks like with all the complaints about the hex bar, I will be ordering the Tangerine system before too long. Everything I’ve purchased from Chris so far has been above and beyond quality.

Sync-Link is the best, CSP bellcrank is next, round crossbar is better than hex crossbar. You will also need a cable bracket from 914werke cable stand

I’m not going to say hex bar, or crossbar are the best but the reality is there are millions of them on the road in VW’s of all types and of course the 911 set up is a crossbar.


Basically that setup is all we had for quite a long time.

Weird the amount of hate I see for them. (IMG:style_emoticons/default/stirthepot.gif)

Interesting that the OEM Porsche 6 cylinder linkage is essentially the same design. (IMG:style_emoticons/default/lol-2.gif) (IMG:style_emoticons/default/lol-2.gif)

(IMG:style_emoticons/default/agree.gif) except for the part about being easy to install.

The installation requires some understanding of the system and drilling holes in hardened linkage pieces. After installation, synchronization of the carbs is straightforward and easy enough (if you can find where you left 2 of your 11 mm? open end wrenches). (IMG:style_emoticons/default/biggrin.gif)

Currently entertaining the idea of building an intake system with a single throttle body and eliminating multiple carb or multiple throttle body synchronization issues. Have the parts, just need to invest some time - after the motivation hits (IMG:style_emoticons/default/smile.gif) .

factory engineered system on the six ,however only as good as the sum of the parts ,mine was worn and required replacement of several of the rose/ball joints cause I couldn't get them right otherwise ,night and day after repairs, haven't touched it since.
Bellcrank system is the best for those on a budget, the geometry is streets ahead IMO ,the owner of my last build took a budget solution so I imported a chinese knock-off and found it pretty well made but replaced the poor fitting rose/ball joints with CB Performance ones.
Easy set up and worked well ,cheers.

I've been running a hex crossbar setup for 40+ years

tough to argue with 40+ years

I was unable to get the hex to work well (IMG:style_emoticons/default/idea.gif)

Yes, they're good. Until they aren't.

It's age and wear, particularly the wear that shows up where they pivot that causes problems.

But like everting else on these cars - if you’re tying to make old worn 30-50 year out parts work - you’ll always be left disappointed

It’s a good conversation because I suspect there aren’t many CSP or tangerine linkages out there that are being daily driven for a decade or more to cause the wear we saw on the hex and crossbars linkages. Time will tell how the newer linkages wear over time.

The other thing is there was a wide variety of quality of crossbar linkages and brackets. Some were really hokey stamped steel and flexible and others were rigid cast aluminum.

Like everything in life, quality matters.

Then add on top of that the number of carbs that had worn throttle shaft problems that don’t sync properly and had the problem blamed on cross bar linkages.

Bottom line: I really like Tangerines system and the CSP is great too but if that is all you have or can afford - the crossbar systems aren’t as bad as some have portrayed them over the years. The better cross bar linkages had pivot balls and cups that were replaceable. There are new 911 crossbar linkages still being sold to replace the 911 linkages that are simply worn beyond hope and repair.

One other note: no carb stays perfectly adjusted or synchronized over time. Jets clog. Needles vibrate and move. Linkages move, cables stretch, etc. Regular tune ups were the reality of the day when carbs were king. Expecting a carb setup to be trouble free like modern EFI is always going to leave you disappointed.
