- Finally, its time to Weber 34ADM swap my TB42 patrol! in this video I will walk you through how the swap can be done, some limitations and and letdowns, and the results! spoiler, I'm getting 12L/100km and the car is quicker then stock. hope you enjoy!
Hey mate I have a few questions
How did you adjust the idle mixer screw. I’m trying to figure out how to do it but i can’t find much information about it and its driving me up the wall
Hey Trav, Awesome video mate. Have given me some hope with the TB42 Shorty!
I'm shocked you were even getting 17L per 100km with the stock carb. I'm currently 25L+ per 100km (I try my best to take things slow as possible also). I am thinking of copying what you've done so I can afford to run the car long term. Do you think running a snokel set up with this will work? If I used the airbox from an XF Falcon and rigged it up to my already existing snorkel it should work and still get good fuel economy and performance?
Thanks again mate. Been a big relief coming across your video.
thanks mate! snorkel and falcon airbox shouldnt be too much of a restriction and i doubt youd notice much of a difference to be honest. and yes the stock carbs are woeful...
Привет) подскажи где взять такой карбюратор,,, или подобный… не могу конкретно такой найти
Hey Travis.
Great video mate, really cool projects.
I'm curious if the 34ADM Weber is often just referred to as an ADM Weber or are these two different models? Though you might know the answer to that. I also want to put a Weber 34ADM on my TB42 but am seeing a few ADM models and want to know if there is a difference. They look the same minus one may have a pipe sticking out of the throat and one does not.
@seanpepper92 i believe they will be the same just check that the bores are 34 and i think they should be the same
@@TravosGarage Thanks Trav, I managed to get a quality refurbished 34ADM so it's the same as yours. Would you consider the stock jetting in the 34ADM ok to try out if I have an EGT to monitor?
Also Trav, to get all the necessary tune readings real time and just to get a quality tune at home, what other sensors would you extend to if you were running dual fuel? can you please list the sensors you would call well suited to always know the tune and operation is in the safe zone, even if under load or climbing hills for example?
e.g. O2 sensor? (I don;'t have yet), EGT (I have two that separate front and rear three cylinders for better problem detection) is anything else advisable for vast information purposes, maybe a water temp guage.
I much appreciate your help.
@@seanpepper92 the only gauge that i would recommend is an afr gauge, it will show all you need to know about the state of tune at any given time
@@seanpepper92 egt wont tell you much, stock jetting is a good start to go from though
Great vid once again mate you did a great job installing the carb. She's looking mint what else do you have planned for the old girl.
Thanks mate! Ive got heaps for her planned yet, for now though just making it a bit nicer and tidier before it gets a makeover
Yeah that's it mate good on you
the redline adapter for the holley was perfect, for me. is the webber like the holley dies on any type on incline? no good for 4x4
The weber has been great on inclines, will keep running up pretty much everything if your on the throttle slightly, the only time ive had it die is rolling backwards down a hill i couldnt make it up so it was at idle. Only just died even though.
Hey Trav, could you post a pick of the vacuum and fuel lines going into your Weber? Did you run a return line from the carb itself? I've got one to fit to mine, but looking for the detail on the fit up. Cheers!
Hey mate! If you havw instagram message the channel account on there and ill send one through! Otherwise you only really need one vacuum line and one fuel line, one vac for ignition advance. The rest can be eliminated, my carby fuel return never seems to open so ive never really needed it, all the fuel shutoffs can be taken out and plugged as you probabaly wont need them
I’ve heard with the Holley Carbys at a steep angle it will mess up would that happen on this too? Thankyou
this should be much better then the holleys, pretty much good on any angle as long as you are slightly on the throttle, but will stall out at idle
Hey mate did you update the adapter plate at all and what carb kit did you use?
hi mate havent changed anything as i am heading in a different direction with it now. carb kits are available online on ebay.
Hi mate are jet sizes stock and was their much in way of tuning any tips cheers
hi mate, cant remember my jet sizes as mine wasnt stock to start with, but 250 crossflow jetting should get you pretty close.
Any one else done this results thanks
Hello mate I just watched the video, and I have a question: is the Weber 34ICH also works for the same car?
Thanks a lot
hi mate, honestly im not sure, but if it has the same bolt pattern on the bottom im sure it would
The Nikki is a good carby, 39mm secondry &35 mm primary. The adm34 is smaller than rb30 carby. Have you tested with o2 sensor/ gauge and set your mixtures through rev range.. Is you vac advance working and hold vac/timing? The spring in vac secondary is same as Holley ones. Sorry m8.but going backwards is not my thing (years on a dyno up my sleeve)
The nikki may have the bigger bores but that means little for the carburetor, they have an overcomplicated and poor design, and the facts do not lie that I have never seen or even heard of someone with a nikki carbed tb42 getting better then 16L/100, ask it on any of the group pages. I've got an AFR sensor and gauge in the car at the moment and the weber sits at about 13/1 most of the time and about 12/1 at partial throttle. My vacuum advance is working correct and the timing has been set to best suit the mixture. The nikki carb flows 330CFM whereas the weber flows near 400CFM, so even though it has the smaller bores it flows better. The smaller bores also help with throttle response and torque as the carb can maintain higher velocity past the venturies at low RPM, the weber also has far more efficient fuel atomization which helps fuel economy and significantly cools the intake charge (which is great for power) to the point where my intake builds condensation on it. Overall the weber is by far the better carb. And I'm not saying there is anything wrong with vacuum secondary's, I'm just saying that's one less possible vacuum leak, one less diaphragm, and a bit more compact and simple, hence I prefer it.
@Timothy Iorlano exactly right! very common and popular carburetor upgrade in the classic performance 6 world!
Hey mate, where would it be possible to buy a Webber carby to suit a tb42. Do ebay or could you recommend a supplier. Thanks mate! :)
Good job mate. What's your carby jet sizes?
hi mate, cant remember my jet sizes as mine wasnt stock to start with, but 250 crossflow jetting should get you pretty close.
@@TravosGarage Thanks. Cheers.
I have a simple question, what happens if it's duel fuel?
I'm not too sure actually, I've never really messed around with anything dual fuel, but I would imagine you would just need the right plate to run it on top of the carb and set the motor up correctly
Did you change the whole manifold when you swapped the carby?
I did not, I just took what I had off my spare manifold and plonked it right down on top of the manifold already on the car, the other manifold was only used for mock-up.
Hi mate, I can't understand how you can get such an improvement just by changing from one carb to another. Could you please explain where the difference comes from? Is it a difference in the secondaries? Mechanical om the weber vs vaccuum? on the nikki maybe? If they're both 2 barrels and roughly the same size then there should be zero difference. All a carb does is allow air through, which draws through the fuel with the venturi effect. There's no magic. How can you go from say 22L/100k on a city driven TB nikki to 13L/100? 13/100 is actually slightly better than my TD. (I'm asking for my dad) cheers
Hi mate, its more so the efficiency of the design of the carb. The nikki was too complex to easily and reliably tune, where as the weber is very simple and easy to ajust the air fuel ratio. The weber also does a significantly better job at atomising fuel, after a short drive the carby body on the weber actually gets cold enough to build large amounts of condensation on it (indicating the fuel is atomising very well) and the stock carby was never able to come even close to this, indicating that it was not atomising fuel well and was rather feeding still liquid fuel to the engine, i could comfirm this looking down the intake while the motor was running. I hope this makes sense.
@@TravosGarage did you change the Jets to suit?
@@christophermaric5373 the jets on the weber are very close straight off a crossflow falcon, however I did fine tune them more a little bit.
Hi
What is different:
Fuel expenditure, decrease or increase?
Has the engine torque increased or decreased?
using less fuel and making better torque
@@TravosGarage Why not put the efi system
@@-garagehome4444 for me the tuneability is great and it is getting better mileage then the efi ones do anyway. the efi ones run rich stock.
hey mate when you said mixed driving, was that a series of highway and town. and are you only on petrol or do you run gas as well.
Hi mate, when i say mixed driving i mean about 80% highway, 20% town driving. And i run it on only petrol
Travos Garage yeah awesome mate. How’d you go hooking up all of the vacuum, fuel lines and auto choke?
@@maplesyrup1088 the only vacuum thing you need to hook up on the weber is the distributor vacuum advance, the rest can pretty much be plugged off or deleted. fuel like is just a matter of putting a fitting in the weber and hooking that up too as they have the fuel inlets in similar places, and auto choke only requires one positive wire from the ignition, all pretty easy😃
Is it fit to tb42 patrol auto transmission?
This one is tb42 manual, however it will fit to any tb42
Hey mate will the Weber 36 do the same job? can't find a 34 on their website.
hi mate, the 32/36 should do the same job, im not 100% sure they have the same base pattern so you would have to check, but they are definitely a similar carb!
@@TravosGarage hi mate, ok no worries thanks 👍 would a Holley do the same economy? I have no idea on carbs
@@bigclan6912 hi mate, if you got a holley the same cfm and tuned it the same it should be able to do the same. but it would have to be tuned correct and be the correct size for the motor
@@TravosGarage ok no worries thanks mate I think I'll try get my hands on the Weber lol
