Rotor, where is the 4 Rob?
lol I laugh at this comment all the time
Now it is here
The end is pure comedy gold
Rob , where's that dahm 4 rotor ?
Yellow Waffle AQ3D iii
More of these videos explaining stuff please 😊
First of all thank you, now it makes sense. I had a rough idea of how it regulates fuel pressure but that simple demonstration did it for me. Now second thing is the ending was so immature but funny as hell at the same time haha. Love your videos man. Good job
I subscribed to this channel for 4WD RX7 but now it's like Engineering Explained. But I'm not disappointed.
+Velikain keeping people mildly entertained while I build it in secret
@@RobDahm I'm using a tbi pump to a qft bypass reg to a proform 650 does the manifold tube have to used and guessing that tube is on the outlet side?
This is the one of the best explanations on youtube on this subject and I've watched many.
your video is very informative in explaining that as power changes so must PSI. People who watch most UA-cam tuning videos only understand "oh, just add fuel. oh get bigger injectors, etc". what Rob is explaining that each injector has a sweet spot of PSI and this is crucial for tuning high power engines. this is why "adding big injectors" isn't a smart mod for most of you guys since you aren't properly feeding the injectors with enough PSI and are probably over working the stock pump. "adding bigger injectors" without proper PSI will lead to the dribble, which will lead to idle problems and low end power decrease
Ur partially right, adding a bigger pump and bigger injectors and properly tuning ur engine using software or a standalone ecu or ramping the factory ecu is another story. However, using a fuel pressure regulator, usually rising rate, is a mechanical way of increasing ur fuel that is sent to the engine, so that u dont have to deal with tuning ur engine as much.
I skipped around and 4 minutes in it looks like your making a bong haha
John Goldstien No its the "Intake Manifold"
@4:20 exactly looks like a bong lol
Rob you're much smarter than Bill Nye. Don't put yourself down like that
NeverStopPulling hahahahahahahahahahahahahahahahahahahah only two genders bruh.
NeverStopPulling I love your logic
thatallredheadude yeah im a radical leftist and bill nye is literally just an actor who is vaguely liberal catering to liberals... hes sort of like a science teacher but isnt really either a teacher or a scientist
Rob is an expert scientist in getting laid and a scholar in secretly building LSX swapped rx7s instead of 4robors

Thank you for the great video! I loved the illustration as well 😂
This video really Dahms it down for me good! Nice work Rob.
Actually learned a lot Rob, thanks!
Great video I enjoyed all of it😂😂 love the way you demonstrated it.
A video from the blue garage! What a throw back UA-cam recommended me!
Thanks Rob Dahm, that was very informative.
Very Educational Thank you Rob
Dude I think mine went and and just as I was thinking about it this video came up, I didn't know what it was until now, thanks so much!
awesome man, great work
Can you explain an oil catch can, and will I need one for my upcoming boosted ka?
Hello Rob, Nice video and keep up the good work...
Very informative! Great video man
Love the video. Going to add an aftermarket fpr to my 4AGE.
lol seeing rob in a hardy shirt is trippy
Good job explaining this Rob !
Awesome video
You have such a pleasing voice
This guy can explain hella good
zahin8 and why is it connected to the fuel tank?
I love the fact that even tho I watched this a few years ago when it came out that as soon as I saw it I had to watch it again.
awesome video, lmao another gold ending!
I needed this explanation
The end was the best
In this video. rob shows us a bong he made out of a 2 liter bottle and one with a water gun
Helpful video!
Holy shit that was unexpectedly educational. Very well explained. Thank you.
Great explanation!
Rob we are learning with you bro, thnx a lot
Is fuel regulator can install into a carb engine?
Informative
Good video, do fuel regs play the same role in turbo two stroke applications?
Hello rob i wanted to get into rotary and i got a question, how many miles are the apex seals good for before i should change them?
Good, suscribed
Thank you mate. Great video
Hay, can you tell me how can I find the correct fuel pressure should any vehicle has? where online can this info be found.
What happens if u plug up the vacuum line on the fpr
In this video, Rob Dahm test his boosted water weapons for an attack against Rob Spaghetti's noodles.
Hi, I'm rob dahm. I'll never get over that
Love the water gun Rob.
Every time I asked the car accessories shop people, they can't explain a thing, thanks for sharing.
We need a Rob Dahm aesthetic appreciation day. Seriously. This man is attractive. God damn it.
And fine. I'll continue the meme.
Rotor 4 is the where, Rob?
Thank you for the explanation! keep up the good work and when u can please let us know how the 4rotor is doing! best regards from Portugal!
Portugal 🇵🇹 Pensei que era dos unicos
mais um aqui.
André Pedrosa hahah 😂 estamos em todo o lado 😂
Os tugas estão em todo o lado ;)
so glad that bottle bong was at 4:20
Hello from Argentina! Great video!
I first want to say that I'm really new on EFI, I'm trying to learn to convert an old carburator car and I know I can really sound like an idiot with my question.. but what I don't understand and I would really appreciate your comments is what about the regulators without the vacum/boost port? For ex in the case the throttle is closed you'll get a higher dP through the injector and that means higher fuel flow on the same injection time than the rated dP. is there any way to compensate with tunning? lowering injection time?
Thanks in advance!
Bit long, but referencing the regulator to intake vacuum instead of atmosphere provides some flow modulation in that it swings the effective setpoint of the regulator on demand tweaking lbs/hr available from the injectors. A sensor mounted on the fuel rail referenced to atmosphere would show pressure changes as engine demand went up and down.
The ending was priceless bro. I was drinking water when you said that's totally after sex and laughed so hard my mouth became a fuel injector. XD
Next video, what are tires and why does a car need them lol
Nice 👍
My turbo slice still hasn't arrived who do I take that up with?
can i use this on stock injectors?
I get F1007 and F1014 codes still searching what they mean. Somebody suggesting it may be crankshaft or timing issue, maybe crankshaft sensor, but I doubt car could be out of timing as it was not opened. Someone suggesting it’s a fuel problem perhaps too much fuel. It’s a Peugeot 207, any idea where to start?
Pls correct me if i am wrong; Injector is not inside the cylinder(located behind the vavles) and hence no pressured air would block the fuel injection.
I always thought the vacuum line was teed into the system only for the "rising rate" fpr's that raise pressure when in boost. Wonder how a rising rate fpr is mechanically different.
If the fuel comes in from the fuel rail on the left, and the regulator lets fuel go through it and back to the tank if the pressure is too high, then what is the pipe below the vacuum pipe on the right for..?
Where do you load the weed?
I have a question Rob, what bringed you into cars? Following from Italy^^
How does the vacuum line hook up to the fuel regulator? Does it come from the factory assembled wrong?
So does this also include carburated vehicles. Cause I hardly ever see this on a carbureted car.
i love you
I diagnosed my bmw e46 318d. And it said fuel pressure regulator cuircut low. I didnt have the diagnose thing before. But i car suddenly got super slow but wasnt in safe mode. So i thought it was the turbo and changed it. But the car was still as slow as it was before. Then i diagnosed it
Ah wake me up before you go go!! George Michael is so hot working on car engines!
the title says it all lmao
why's rob making bongs?
Next week by Rob Dahm: what is a steering wheel and what does it do??!!!
the wespaul LMAO!! roasted 😂
I was going to do "What is a gas pedal" next lol i started the channel with simple videos like this and i enjoy going back to my roots. if it helps someone then im satisfied. Obviously not going after the big audiences with videos like this.
Rob Dahm or are you out of video ideas? Finish your car Rob.
the wespaul and why is it connected to the steeringrack?
Rob Dahm would you like to enjoy your fried chicken after its been in the fridge for a day? let me show you how...
Would a old fuel pressure regulator cause a hot start issue? Turn car off and fuel up, pay for fuel come out won't start
What I don’t understand is that on a turbo car manifold pressure will be positive whereas on a non turbo it will be a depression. After market pressure regulators don’t mention turbo or non-turbo
so you have to have more fuel pressure than boost pressure?
Next episode, the engine and what it does.
Hi, I'm not Rob Dahm
Does anyone know what those connections are holding the regulator to the fuel pressure rail the 2 blue and red pease in the middle 1:00
i had never thought of that. i mean i figured it was something like that when ypu made the bong, i mean water gun, but now i know that
Bicycle inner tube valve stem . I think he said bicycle pump gauge . We all know what he meant but just for the record .... not trying to be a smarty jack just clearing. Nice vid .
My plastic 6mm vacuum hose is disconnected how do i fix that
How would that szenario change if it would be a n/a engine?
It really doesn't change, vacuum from the intake manifold still creates vacuum, the FPR still senses that vacuum and adjusts the fuel "take or put". When you hit the throttle under acceleration the intake creates more vacuum, the FPR sees that increased vacuum on the diaphragm inside the FPR. The diaphragm moves allowing more fuel (in aviation we call it "putting"). When you take your foot off the throttle, the intake draws less vacuum, the diaphragm sees Less vacuum then reseats and "puts less" also referred to as taking. Rephrased putting is putting in more fuel to the injection or carb, and taking is taking fuel away from the injection or carb. Adding a turbo Just increases vacuum and so increases the put. Does that make sense?
é MoiśT Power-Phull Explain-Ásiân 👍👍👍
You trying to explain this with pop bottles and squirt guns is comiccal
Dahm, the 4 Rob rotor is where?
Explain how a squirt gun works.. Or magnets!
i climbed the wu tang mountain and i asked the Dolly Lama where the rotors at. he answered: rob is the 4th rotor.
Basically, the regulator maintains the 40psi differential.
If the intake was pressurized to 20psi from a supercharger, the regulator would sense that 20 psi, and then automatically adjust the fuel pressure up, by 40psi (60psi in the fuel rail total)
.
What is the purpose of a mustang? Driving or Killing? Why is it linked to car meets and crowds?
Where should i hook the fuel pressure to the manifold.
As my friends call it the fuel spray thingy
what if connecting hose is damaged?
Hold on. If the bottle was at 10 psi and the gun was at 15 then at first it would be 5 psi to the bottle.
I don't know why this guy has over a million subs with a title like this. The FPR connects to the Fuel Rail. Which?...Wait For It.
A donde está el 4 rotor Robster?
My reg doesn't have a fuel-return or vac line :(
i love how childish rob is, reminds me that he is human xD
"Intake minfold " looks just like a bubbler lmao
😂
So what's the problem with having too much pressure?
Because when you pee it gets all over everywhere
