Will these newer HPMX carbs work with a blow thru turbo?

If so, does one need to do any mods to them and where would one get the "Hats" to do this?

They are identical to Weber carbs, so anything you can do with a Weber you can do with an HPMX.

I'd call CB Performance. They have been working with blow through turbo systems since the 80's. They have catalogue you can either down load or open and look through they have tons of stuff for your application.

i had to log into this site just to ask about these weber/empi/whatever carburetors.. as it seems many of the google links seem to point out to thesamba forums.. so i bet there are people whom might know something about something..

ok.. i found a new twist to the weber-empi story..

i found a chinese copies of weber idf40 and 44.. called FAJS idf40/idf44..

they are made in china and company name on the plaque says FAJS not EMPI.

So are these FAJS carbs infact the exact same EMPI hmpx carbs? are they just labeled differently when sold in china etc?

Or are they local chinese copies of empi carbs? clones or fakes made with lower quality than the ones sold overseas?

low grade fake copies of copies of the real thing? are these the official chinese junk one should avoid?

all scenarios are common in china it seems..
-"real" things sold under different name..
-slightly downgraded or QC control failures sold under different brand..
-making copies/fakes/clones of the good selling item.. (sometimes under different name sometimes sold with same or similar name)

google dont really find anything useful of FAJS brand..

the seller ofcourse says "these are sold as "empi"brand in usa". "the parts interchange with weber" but that like everything else should be taken with grain of salt.. he wants them sold.. he might say what ever that helps his cause. hahah.

-and yea.. not putting this into a veedub.. dont have one. but lookin into changing an old sloppy badly running single barrel carb out of my amc. :)

price you wonder? about 160 dollars.

Your Google-Fu is a bit weak this day. One of the chinese companies on Alibaba has this info:

Company production of more than ten years, this product sales to many countries in the world, for multiple company production.
VW Apply Car’s Model 40HPMX VW TAREK
VW Apply Car’s Model 44HPMX VW TAREK
Brand name: FAJS

Most likely(IMHO) they are exactly the same carburetor with a different badge/without one. The company has supply capacity of 100000 pieces of 44s alone per year, so I don't think EMPI buys all of the carbs they produce. :wink:

What many people may(or may not) already know that quite a lot of the stuff branded as "fakes" are done by the very same factories as the "real" ones. A company has all the tooling it needs to make more pieces, so why not make some more?

As you said, all that stuff should be taken with a grain of salt. There is a big possibility it is exactly the same and also that it isn't. Who knows? I sure don't.

oh.. alibaba.. i keep skipping them as they dont sell anything for 1pc at a time.hahh. (and couple times my virus program turns red on entering the site for trojans) so i skip those links..

but thanks for finding that out. (i know that one link to the company making them had also listed weber idf40, empi hpmx, and fajs idf40 as products they make. and weber venturies etc. kinda dont believe they are making webers there with factory concent?)

yeah the companies make tons of items there.. some batch of the total might get better qualitycontrol and different label as they are sold overseas for reputable name. the company ordering the item might ask alot tighter tolerances and speficic materials etc.

when the order is filled: the dies and stampings and workers may be still used. to make similar items to be sold inner market or under different name brand. these might be sloppyseconds with little less QC. (the ones that werent in tolerance asked by empi for instance) or they might just be made of inferior materials (softer steels etc.)

boker knife that looks like böker might be böker by another name, it might be just as good, or it might be seconds/irregulars that didnt make the qc cut, or it might be lookalike made by same company with worse steel, or it might be inferior junk fakecopyclone made by crap company who wants to get easy buck by selling lookalikes of reputable makers items.

its confusing there.

i just wonder if someone knows for sure if they are infact the 99.9% empi (0.1% beeing the wrong name label) hahah.

and my google-fu is mediocre at best.. as im more anti-google entity.. i search alot of things there but weirdly i am often able to search things it cant answer rightaway.. hahah.

Current Weber castings are indeed made in China then machined in USA. The official Weber carbs look a bit different and have a flat casting on one side compared to italian/spanish or HPMX.

Current opinion is that the "real" webers that are made in the USA are worse than the clones

Hello.
Today I had the "pleasure" to prepare and install my first set of the new generation Empi IDF´s. And I must aggree with Harney. Apart from the usual cleaning and presetting, the carbs were very easy to get working. Idle was almost spot on in the basic setting. the maincircuit - still - has too small main jets and too large air jets, at least for our fuel. I installed the carbs with the flimsy Redline type of throttle linkage, which the owner thought was fine, until he saw an engine in one of my other customer vehichles presently on the site. Then he immediately ordered a new session to have his own replaced.
Throttle respons OK
Idle circuit OK
WOT OK

I do have an issue with the engine coughing a little at too much thottle in the 1700 - 2100 rpm range. But I think that is due to the less than optimum exhaust (its a trike) and the fact that these Empi IDF´s has a throttle body kinda similar to the IDF 68/69, which means that they are actually too large for a little 1600 cc engine.

Soo, for that Empi recieves 1 star. - 5 to go :roll: :D

Time for a review of the Chinese "Fajs" carb.When a set of Fajs 44 cost about 1/3 of the Empi:s I bought a pair just to test on my 1776.After setting the floats(way off)they were easy to tune and the engine ran surprisingly good with almost 100hp at the wheels.The downside is that the throttle shaft bearings is almost worn out after less than 5000km.Sometimes you get what you pay for :wink:

No such thing as they were never set up by OEM VW for air-cooled VWs.

Oh, I was thinking in terms of OEM use from the factory... my mistake.

I hadn't heard about Decade Parts until getting the new Hot VWs in the mail last week... asked over on the Cal Look Lounge, but all I got was Richie Webb cyberstalking me from an offhanded comment I posted elsewhere about shitty attitudes on the lounge by people who take shit way too seriously... the only feedback I got in that thread on Decade was a guy that posted up the web site link. :roll:

I just purchased a set dual HPMX 40s including the `ultra linkage kit' which is EMPIs billet set w hex linkage.

$677 shipped and I live in Hawaii. Ordered them from doghouserepair.com

With equivalent Weber kits going for $1,000 not including shipping the HPMX kits are an excellent choice IMO.

They work great! Not one complaint about them..I even prefer the EMPI heim joints to any others i tried.

When I get them, I take them apart and clean them, make sure all the screws and jets are tight set the floats and enjoy. Do the same thing with real Webers.

Bugnut68, I helped my son installed a Decade 40 on one of my sons VW club member in my shop and it all when pretty well, they only come jetted for 1600...spoke to Enrico at Decade and he claims that if you buy their kit, they set the float level, check to make sure the throttle shaft has no play and snap back correctly and make sure everything is nice and tight....from what i can see it looked pretty good quality, it performed very well, this carbs do not have a vacuum port, only time will tell if the bushings wear earlier then expected, i really did not see any other thing that stood out, do im not a carb expert (my shop works on Hondas/Acuras all day long) i may get 5 or 6 aircooled cars a month....It really looked like a good product for the price ( i think he paid $569.00 for the kit) and you can't beat the warranty (as long as the company is around).

I got the impression that the part about bronze bushings was referring to their line of stock replacement carbs. Same for the part about OE jetting. I could be wrong....

Also looks like the carb in the bottom pic has a vacuum port with a screw-in plug in it.

If i recalled i think i looked down the throat of the carb and did not see a small passage above the throttle blade so you can make a SVDA work properly...if you have a 009 then you should be ok, when i get another one in the shop i will look a little closer in to it....again the quality seem to be there and the price is right so im sure we will see more of this decades around in the future.
