Oh hai Fuel Injection! I make just as much power as you, if not even more...

'sup you senile old piece of shit, how's it feel to be completely irrelevant outside boomermobiles and dornorcycles? How's it feel knowing you'll never get near the power I can achieve, or the mileage? Pic related, its me and my bitch

Until recently, drive by couldn't be interfered with remotely

kek

even NASCAR doesnt use that shit anymore

carbs are garbage

>SU carbs with a manual choke

To be fair Carbs, are not even relevant with donorcycles.

None of the top Supersports or Superbikes use them.

You sound like my uncle.

Well you see gramps, everyone has a laptop, but not everyone has such specialised equipment as a screwdriver. Get it?

Kill yourself my man

What's it like adjusting your throttle linkage and metering screw every time you fill up at a different gas station?

What 3rd world country do you live in

I'm coming for you

What does a carb do to adjust for air density and barometric changes?

Oh, thats right. FUCKING NOTHING.Enjoy using that screwdriver on the side of the road to make your car perform when the temp changes.

yeah have fun trying to start in anything but sunny 70 degree weather

So you don't know to tune or rebuild the thing is what you're getting at? Because I have a Qjet with no choke fueling a high compression 468 and all I have to do is pump the gas three times and it'll fire on the first key turn even on 40ish degree mornings.

It starts and runs and the car isn't used enough to justify pulling something that is currently functional enough apart

Its also much farther down on the list than a few other pressing issues with that pile

also the later quadrajunks suck

one where people dont put shitty smog era or plastic chinese ripoffs carbs on their performance vehicles

cbperformance.com/category-s/342.htm

Carburetors are more simple to manufacture and work on. If you were trying to make a simple, rugged engine a carburetor would be a better choice. For a modern vehicle with access to modern maintenance equipment and techniques there is literally no reason to go carbed.

auto jacks baby

Lmao fuck off boomer. Even ktm 2smokes will use EFI now, to get within euro4 parameters.

The main advantage of EFI over turbos becomes apparent with turbocharging. You know how much of a pain in the fucking ass it is to tune a turbo carburatted car? No, you don't, and that's why turbocharging wasn't common in anything but racecars before fuel injection simplified things. Turbos wouldn't have achieved their current popilarity in the tuner and hot-rodding scene, for instance, without EFI.

With an EFI, tuning an engine is a matter of minutes. With a carb, it's a matter of days.

just put fuel in the turbo

>Willing living in a communist shithole.

No thanks, I enjoy owning firearms.

>buying a meme carburetor that's part of FIAT group

All the carb'd vehicles I've had have been known for having good carbs, and I always tune them. I've never had any of these problems.

Always easy to start, no issues with temperature or altitude.

I have to admit I do find all the sensors that go with efi and start failing after 10+ years pretty annoying.

Those god damn malfunctioning o2 sensors always fused into the exhaust.

In my experience both systems are very appropriate if they're taken care of and decently maintained

What do you memers recommend as a good starting point to tuning twin SU carbs? A carb balancing tool, a colour tune and a decent book on SU carbs? Anything I've missed?

Underrated.

Patrician taste, user.

What about the rape baby TBI?

Plan to use one of these on my weiand 174 instead rb because fuel injection (even if its not god multi point) is comfy.

Isn't this like the worst of both worlds?

Yeah it really is. Single point fuel injection was a horrible invention to bridge the gap between the available technology post cats in the early 90s and the cheap technology. Luckily by 2000 SPI was only found on total shitters

EFI is superior in nearly every way, and this is coming from a mechanic of many years

only carbureted vehicle i have now is a Subaru Sambar purely because i want something simple that cant be damaged from EMP. i had a carbureted 81 Toyota Hilux and it was nothing but issues, it would run fine then run like shit a month later. got to the point i sold it to someone so it wouldnt sit for months on end after i ripped my hair out

i dont mind TBI, i had a 88 Nissan KingCab with the electro injection 2.4 TBI engine and i drove that thing in -50c one winter

everythings got their pros and cons but i think carbs are looked at with rose tinted glasses, they still have their place but the advancements weve made in the last 30 years are huge

yeah are you retarded? that's just a stock image

Teach me your strange and mysterious ways.

Carbs are simpler to install, more difficult to tune well and have inherent driveablility issues which are exacerbated with changes in temperature and elevation.

EFI is more difficult to install and manage, but properly mapped and managed does away with virtually all driveability issues. TBI is a step up from carbs, MPFI is EFI perfected. Direct Injection is gets you more power and fuel economy at the expense of carbon buildup, maintenance and initial cost.

Same way I'd rather an MSD ignition box than points or HEI, I'd rather have EFI over a carb.

>I don't own a screwdriver but I own a laptop
Woman detected. Tits or gtfo

I just set my valves after a new hydraulic cam. Started a good 20 times in 30F weather, only needed to pump the gas on the first one
Wat r u doin rong?

>not knowing anything about SU carbs

do you even know how vacuum advance works

you need to rebuild your carburetor, or maybe buy a new one.

Peak power? Sure.

More power across a wider rev range? Not a fucking chance

What is with/o/s obsession with retard machines like superbikes and supercars? You don't see /k/ creaming over $10,000 boutique rifles and racepistols nor does /g/ dream of $3,000 enterprise-grade CPUs. What is the purpose of even acknowledging the existence of such machines?

because some people on Veeky Forums can afford them

These don't work when flipped upside down.

I demand my vehicle preform under ALL conditions. Last thing I need is for the engine to die after the car flips upside down.

Semi related question.

How do light aeroplane carbs work under changing altitude and orientations?

It was actually a problem in early Spitfires.

en.wikipedia.org/wiki/Miss_Shilling's_orifice

They don't.
Planes with carbs have a low service ceiling and can't fly upside down for very long.

I don't know all the details but check out
en.wikipedia.org/wiki/Pressure_carburetor
and wiki walk from there

the Spitfire's acrobatic performance in WWII was a big push to address these issues, which are not that problematic under normal upright flight.

Sounds like they had three stages

Carburettor

Pressurized carburettor with added float control

fuel injector

Yeah no. Nobody here has a Ford GT and if they say they can afford it they are lying. There are people on /k/ who routinely post collections worth $30,000+ but you'll never see anything worth more than $3,500 by itself because it's generally considered to be wasteful and stupid to buy such things as the only thing you can buy above that point amounts to either snake oil or "master craftsfaggot Hurrist McDerp built this rifle and Butfuk McBride did the engraving so of course it's worth $20,000," which you will be rightfully ridiculed for buying instead of a blueprinted Remington 700 that probably performs better and still won't cost $5,000.

Also what's with the obsession with pure speed?

Oh hai, Carb! I make the same peak power as you, tune myself so you don't even need a screwdriver and pay for myself in fuel savings at just 15k miles. And have a stable idle. And start in mid-winter on the first crank. And re-adjust myself when you throw new parts at my host engine.

There's full-sequential multi-port injection kits too, but at twice the cost it takes twice as long to pay for itself. Still, fuck you Carb.

0/10. I would kill for fuel injection. Done dicking with carbs soon...

Only shitposts get any responses around here how new are you

a little greentext helps here and there too

Light aircraft pilot here. Reciprocating-engined aircraft have a knob/lever that allows the mixture to be adjusted directly. Not sure about more complicated engines, but on the carb'd/aspirated 1970s shitbuckets I fly, you're supposed to shut down by leaning mixture control rather than cutting ignition. In an aircraft without an EGT sensor, you find your mixture by leaning until the engine starts to crap out in flight. Can be kind of funny if you have a passenger along.

Maneuvers are normally coordinated, meaning the force on the entire airplane is is straight below the aircraft, regardless of bank. Most uncoordinated maneuvers (slips, spins) are transient or mild enough to not cause fuelling issues. Sustained aerobatics require a specially-designed fuel system, tanks to injectors/carb.

As for service ceiling, the Cessna 152 I usually rent is certified for flight up to 14,700 feet over sea level, and can still fly even higher; I've read about people getting them over 18,000. The pilot is only allowed up to 12,500 if he doesn't have supplemental oxygen aboard.

>pay for myself in fuel savings at just 15k miles
My Camaro gets 15 mpg. If FI got it to 17 mpg, then it would take 110,000 miles to pay off a $2,500 system, FAstGGOT.

You can do fuel injection without modifying your fuel system at all for 1200. Gotta love maturing technology

well your gonna hafta buy random air fuel intake exhaust reatio rtemp sensor first it runs about 150 new and you should replace all 6 of em and the o rings and then pressure test and reboot comp but then you get to the good part then you can chase a misfire for 4 hours to find one vacum leak

or you can ditch fuel injection sell it to a retard for 500 bucks and buy a carb and intake for 10 bucks?

>Lies
Wrong
A DCOE costs around $400 and it's the pinnacle of performance. You'll need to buy multiple though.

Because of emissions, just like F1.

Because of emissions. Carbs are still coming equipped on dirt bikes even. and most manufacturers didn't bother switching until the mid 2000s iirc.

>>plus new jets every time you need to tune it
You can literally clean jets with a bottle of water.
You don't need to buy new ones after the initial tune.

>>plus hundreds of dollars worth of wasted fuel because it isn't delivered efficiently

You always want to burn slightly rich anyway.

>What does a carb do to adjust for air density and barometric changes?
Same thing FI, nothing.
The only thing that can put more air into your engine at high altitudes is forced induction. Fuel injection doesn't magically increase atmospheric pressure.

>yeah have fun trying to start in anything but sunny 70 degree weather
I have literally started my carb'd cars with slow-spinning starter (from the cold). I have never not been able to get them started in the cold. You suck at tuning a choke.

>not living in America

>>have to crank for 8s and then hold the throttle a 1/4 for another 5s to get it to hold idle
if you let it sit for more than a week the fuel will leak back down the lines and the pump will have to prime the carb all over again.

>hold the throttle a 1/4 for another 5s to get it to hold idle
This means your choke is out of tune, your fast idle cam should have done this job for you.
Git the fuck good.

>Carburetors are more simple to manufacture
The fuck they are lmao.

Carburetors are extremely complex dumb machines.
No one in this thread could build a functioning carburetor from scratch.

wrong

>to get within euro4 parameters.
This is the true reason carbs died. They don't work with catalytic converters. Emissions are what done them in.

That's retarded. A good intake used won't be less than a hundred and a good carb is minimum 50.

Besides, EFI is the titties with the current class of tech. I would totally buy this if I had the cash.

The 400hp version costs like 200 less

jegs.com/i/FITech-Fuel-Injection/546/30002K/10002/-1?CAWELAID=230006180009847818&CAGPSPN=pla&CAAGID=15769068431&CATCI=pla-208663438631&catargetid=230006180037476986&cadevice=m&gclid=Cj0KEQjwnsPGBRDo4c6RqK-Oqu8BEiQAwNviCSxzNQ5ZZSMZpIsC-b0LU45_R6VhflQa-IbvLNFb_eAaAuux8P8HAQ

They're easier to fix yourself.

>With a carb, it's a matter of days.
False, it's a matter of a screwdriver.

It's pretty much the top tier carb.
The most efficient carbureted engine is one that has a single barrel per cylinder and webers achieve this.

>a good starting point to tuning twin SU carbs?

>the worst qualities of carbs with the worst qualities of FI.

These kits exist only to convert old engines without needing to spend $10k on a custom MPI setup.

>EFI is superior in nearly every way,
wrong

>that cant be damaged from EMP.
Good luck killing FI with an EMP tinfoil. The whole frame of the car is a giant Faraday cage.

>more difficult to tune well
I disagree, this is only because it's a dying skillset.

>changes in temperature
If your choke pulloff is working right this isn't an issue.

>More power across a wider rev range? Not a fucking chance
This is the main problem with carbs and the nail in the coffin.
Any carb that is good for economy is horrible for power and vice versa. it's a set it and forget it.
The only thing that came close to the middle ground was the Quadrajets and Thermoquads which have really small primary circuits for mpg and huge secondaries for power.

this, you're paying for that name.

Neither would FI, the pickup tube sits on the bottom of the fuel tank retard.

>Oh hai, Carb! I make the same peak power as you, tune myself so you don't even need a screwdriver and pay for myself in fuel savings at just 15k miles. And have a stable idle. And start in mid-winter on the first crank. And re-adjust myself when you throw new parts at my host engine.
You're also prone to failure but who's counting?

>a good carb is minimum 50
$50 will get you something that needs to be rebuilt. a good carb is $200 or more.
