Rather have that than a K-jetronic

TBI is a great idea they should combine it with PFI and DI and patent it like toyota and call it D4-S4-T4-B4S

Are those the spark plugs ?

Said every person ever.

>Are those the spark plugs ?
Got it in one. See those metal tips poking up above the orange insulator? That where the magnetohydrodynamic spark jumps after the reverse tachyon field is formed.

TBi is probably the most reliable and simple EFI ever.

tomorrow we'll see about whether it wants to keep dumping all of my fuel into the oil when I turn the engine off, perhaps I'll even see double digit MPG

Thats a big chunk of american iron you got, be a shame if we were to support Jews in a war and put one of these MFs on it so you make 140HP with 307 cubic inches and get buttraped to death by Asian cars for generations.

Modern digital TBI should be a thing. Carbs get good fuel atomization but practically never produce a perfect mix ratio. Also fuel spray upstream of pcv oil outlet would solve all intake carbon problems

>>28963914
Port injection spraying onto the intake valves is probably good enough, my shifty Honda has been breathing her own farts for over 20 years and has never misfire in its life, meanwhile fuel injection service is an actual maintenance item on GDI engines because theyre fucking shit and they coke up and start misfiring.

>>28963914
Just use a wick carb. Waterboarding the engine with gasoline.

>>28963914
>a perfect mix ratio
carb cheater is your friend here. uses an intake air control valve to meter the air trims to whatever target RPMs or AFRs you set it to during idle, cruise and power modes. can also configure what vacuum is idle and cruise etc.

>>28963782
Unironically
They should combine it with DI. Why just wash valves when you can wash your whole entire intake

>>28963607
>>28963780
Were they really that bad?
>German
I guessing it is more complex than anything?

>>28963914
>Modern digital TBI should be a thing.
It is.
All those modern muscle car EFI kits are usually just TBI with a newer distributor to control timing like TBI could.

>>28963851
This is a good video on TBI stuff.

That's pretty cool.
It is kinda gay though.

>>28964230
>muscle car EFI kits
Extremely gay.

>>28964248
Most of em work fairly well.
Ignoring the Holley shit

>>28963914
tbi is the worst of both worlds. You need sensors out the ass like pfi but the fuel atomization and repairability are far below that of carbs. the only reason it ever existed was to meet emissions requirements

>>28964488
>ass talk
carbs don't atomize, they vaporize. Atomization is spraying.

>>28963499 (OP)
Mechanical injection is cooler

i just like that if it breaks, i've just got a regular carb. it's a passive system.

>>28964042
>waterboarding with gasoline.
Fuck, that takes me back. I miss Afghanistan.

>>28965021
>gas leak: won't know until tomorrow
engine did not start "instantly" like I remember, but it did not crank nearly as long as it used to before the gas leak
if i change this oil and it starts filling with gas again i am going to lose my mind

Retard.

Still gay though.

>>28964073
Looks pretty good on his vids. Fast on-the-fly AFR adjustments and if the electronics take a shit, it shouldn't affect standard operation.

>>28964230
Been out for decades. I put a Holley TBI setup on my Riviera, twenty years ago.

gonna bump my dumb thread just because it's one less thread about that fartrarri

realized today that the van isn't making phat clouds of smoke anymore with the new injectors, so that's probably good?
anyway tomorrow I think I'll go measure the exhaust pipes on either side of this fuckin thing, head to the supply store, buy a metal pipe that's a little bit bigger, and swap it for the pipe, and clamp it down tight with two exhaust clamps

>>28968733
Why not just knock the packing out and continue on?

>>28968962
well if I remove it to do that I might as well replace it

>>28969045
Yeh, but you'd get to keep the cool flat pan.
And idk wut ur car is but it will sound different and louder without it, which may not be desirable.

>>28968733
joints have been drowned in pb blaster
I've managed to locate every single power tool I own except the sawzall
gonna try to remove it the normal way, take it to the surplus shop, and go buy a pipe that's the same length and size

>>28969693
We used to open the dog house remove the intake tube and stuff garbage down the throttle body of my buddys rally van when we were teens

File: 1755598639780.png (1.58 MB, 1436x1440)

>>28972369
that's a one hour procedure in mine because I wired a bunch of switches to the center console like a retard and Mark III positioned the seats too close to the dashboard to be able to remove the doghouse easily (also retards)
and the mice have been doing that already, so I have a metal screen of sorts hose-clamped around the plastic end of the intake hose just to keep those little faggots out of my damn airbox

>>28969693
So you should keep the pan.
>>28972369
You're retarded.

>>28974133
isn't a hollowed cat worse than a straight pipe? I want to just swap it out, not have to do a bunch of surgery to it.

>>28974725
In theory it will alter the any pulse tuning the vehicle had. Doubt it would be anything noticeable to the driver if so. It does change the sound some, and not for the better. I mean, it's not terrible but at the same time I kind of wished it didn't have that hollow reverb sound to it and wanted to put a pipe in there but sold the car first.

>>28963499 (OP)
You know you can use tunerpro and a obd1 USB cable and see what the computer is doing

>>28974725
Either option will change the sound and raise the volume but the straight pipe will do more of both than just hollowing out the cat.

>>28974725
hollow cat will be less raspy
go straight pipe for maximum farts

>>28975287
I did not know this
isn't OBD1 super basic?
>>28975310
>>28975360
she still has the muffler so hopefully not super loud but yeah I'll be doing a straight pipe
I've acquired angle grinder now in case it doesn't wish to cooperate when I give it the ole grab and twist

>>28976040
>isn't OBD1 super basic?
Yes, but some have data available beyond codes. GM for example you could see all engine sensors, commanded injector PW EVAP status, etc. Ford's was much more limited in that respect since the EEC-IV was an improvement on the EEC-III of the early 80's and they didn't allow for that level of information in the field at that time. With the later EEC-V they went way the other way. Chrysler stuff was a pain too since the ECM was basically opaque to scan tools of the time. About all you could get was codes and you could get that by switching the car ON three times and reading the odometer display. Luckily about all that bothered them was TPS's and MAP sensor hoses going bad.

Any data was proprietary as were connections so to cover every car you had a bewildering array of scan tool modules and connection adapters which is where the impetus for OBD2 came about. That was supposed to solve all that proprietary shit but had so many loopholes that all it amounted to was a single connector mounted somewhere within a foot or so of the steering column and standardized DTC's. Took decades to get to where we are today with cracked software able to access most everything.

my vehicle just has a carb on it

>>28976151
i'm guessing tunerpro is paid software?

>>28975287
>obd1 USB cable
thew fuck? those exist?

>>28977772
Why wouldn't they?

>>28963499 (OP)
Gonna forget this if i don't post it now: if that TBI is going on a factory manifold, check the throttle-blade clearance and make sure the butterflies are actually opening 100%. Turns out Dodge had that issue, when they slapped a TBI on the old carb'd manifold, on the '89 Gen 1 Dakotas. I found it on my ragtop Dakota and I've seen it on 3 in a junkyard.

>>28976040
Depending on the ecu you can see more data, mine was probably the most unpopular version but I have BLM/INT, coolant temp, TPS, vacuum, o2 voltage, loop status. This is all live too. Most of this is enough for me. Oh tells you the codes too but that's easy anyway.
>>28976474
It's free, you have to look up .xda for your ecu though. I think it's .xda, it's just the defintitons for the data.
>>28977772
It's not much, cost 50 bucks. I think there's a Bluetooth one even.

>>28964167
Yeah, they're really that bad. When they work, they work well, but when they break, you might as well just throw it away. The valve system is black magic with almost no literature on tuning them, and there's only like one guy in the entire US that rebuilds them. It takes one little peice of sediment to fuck the whole thing. Carbs are heavily preferable.
