What does 1400 HP of Fuel Flow look like? 3 Pumps working together

- We just installed the AI SPR1200 external surge tank and couldn’t wait to test how much 3 fuel pumps put out. Maybe we got a little too excited.

Thats how Dahm relieves pressure since No Nut November is finished
Damms loveeee building pressure
😂
All I saw was the huge leak from the fittings when you was filling the bucket...
Glad I'm Not the only one who wanted to point that out.
Was gunna say. 1000hp plus and all you have to do is use oil to make the fuel lines? My Honda was harder technically...lols
It was not tightened. You can see how he rotates it, to get the angle right, to put it in the water bottle.
If you did a "dahm racing" banner or something like that, I would totally buy it dude.
Seconded
Would be more accurate if it said broken car Dahm.
@@husky701rider9 what about "dahm the car is broken again"
Agreed
If something goes wrong with your fuel system it won't be a fuel leak it'll be a fuel tsunami
Ill buy a shirt when the 4 rotor is a real thing
it is?
He's made so much progress on it recently that I'd expect it to be running in 4-5 months.
twinkmaster2 or buy a shirt and help him progress faster?
Buy the hoodi
i thought it was done wym lol, it’s running it’s on the streets and everything
Fuel Consumption: 3 Rotor = Top Fuel Dragster
Glad to see that it was just water Dahm. I was afraid you went full male model and were going to have a gasoline fight
If he went Zoolander I'd probably die
Strong enough to waterboard your enemies!
Rusty Shackleford Our enemies respect, even if they won’t like the comment.
i get you're just joking but if you waterboard someone, you want drop, not a jet stream of water lmao
adza botchway Fair enough...
It is not waterboarding if you use gasoline.
That's some ridiculous fuel flow, holy shit.
For that fuel Flow . I expect to see Huge Flames !!!!!!
You know it’s gonna be a flamethrower
thats just to the rails, that flow gets slowed way down by the injectors.
You need to call the garage "The Dahm Garage" so when the car breaks down you can take the Dahm car to the Dahm garage to fix the Dahm problem.
When sticking your finger in random holes goes wrong 😂. Dude that fuel flow is on point.
Rob you should put some clamps on push on fittings just for safety.
not sure if you noticed but the center connection to the surge tank looked like it was leaking when you were running it
Nic D I think it’s because the hose clamp isn’t on ..
They're AN fittings wtf are you talking about hose clamps for? He just didnt tighten the fitting
@@Rob_Fe They're push lock style on the hose end of the fitting, meaning he does need hose clamps for them.
@@BlownVR you don't need clamps for push lock... It's in the name... Only for Barb fittings
@@krakdaus5442 you can yet these safety clamps that you can put on thr end of the hose to make it extra safe. You slide it on and squeeze it and it makes a more reliable seal when using on fuel, oil etc
U should have had a pic or Silhouette of the 4 rotor on the back
there is
Silver Insight? What happened to the red one?
It's for a nitrous drag race
He has 2
I just realized how much of a hack Rob is but at the same time I respect how he's just not afraid sends it.
you know what we need? A custom laugh track of all the dahm bros together laughing for some of these moments
Can the next video of the 3 rotor be a fire suppression system?
Yes rob because putting water in a fuel system makes complete sense
Do you need some more fuel pumps robbie? ;) Good timing with the video man almost ran out of things to watch!
Honestly, best CZcams merch I've seen.
Rob please build some sort of shield between the cabin and the trunk now that you're running a monster surge tank setup there. Best to be safe and seal that area off!
Lol, laminar flow, yeah right. That hose diameter and flow rate easily puts your Reynolds number way into the turbulent regime. Once it's turbulent it stays turbulent. Those bends help reduce head pressure losses, not to keep it laminar.
Haha you definitely know more than me about it. But you have clarified that there is benefit to the curved pieces. I’ll be more careful with repeating things I haven’t fully researched.
Sooooo... Those pumps depend on the lubrication of the fuel..... Also those electrical connections are not water tight. Same thing with the pumps themselves.
And today Mr. Wob "Daddy" Dahm installs a garden hose in the trunk of his 3 Rotor RX7.
There's doing things the right way... Then there's the Dahm way
Because you only live once
also when locking down any hose lines id suggest a clamptite tool. it uses wire to pretty much tourniquet any sized hose lines. you should check it out Rob
That hoodie.. Already ordered one for myself as a christmas gift.
That hoodie is nicer than most youtuber merch, SMASH THAT BUY BUTTON
Hey rob i just want to mention you need some brackets or clamps for those fuel hoses and you need different fuses you said those pumps draw 7 amps each if you put a too high capacity fuse in it it would still be able to short circuit because it wouldnt reach that peak and still burn down your car
Lol I ordered the sweatshirt before you had to whisper "dahmracing.com" it's dope!
You're an idiot, grow up and realize when you're getting con'd
If that sweatshirt would have some kind of big logo or print on the back I'd buy it. Great vids! Keep it up
Uffff morning wood material😋😋😋 love u Alfa Rob
It’s great watching you do all this work with fuel line as it’s what I do for a job👌🏼
12:55 - that looks like a leak around the outlet of the surge tank?
He forgot the hose clamps. LOL
You don't use hose clamps on AN fittings
Rob Ferreira that isnt a fitting thats leaking lol.. look at where its coming from
It looks like fluid is leaking between the hose and the nipple that he pressed the hose onto to me. Unless it is leaking up through the collar of the AN fitting. Difficult to tell since all the parts are black with no contrast.
First thing I thought off. You could work this out yourself by taking your MPG and speed into consideration. Say you get 5mpg going at 100MPH, well simple math says it takes 3 minutes to travel 5 miles and that would be 1 gallon of fuel, or roughly 1.5 liters per minute used. All you'd have to do is find your MPG at your top speed for max fuel usage?
Really enjoying this raw footage videos with Rob and Jared. It's chill, reminds me that time Rob took the continental for a drive. Never laughed so hard with that one.
Nothing like a tight fit in a nice clean good HOSE!!!!!
Rob: weve discovered oil in my shop
Cleetus: sounds like rob needs some bald eagle freedom machines.
*U.S. Marines come crashing through the doors doing mad burnouts in mustangs, camaros, corvettes and challengers*
I'm glad you've gotten your own shop, so you can do dumb shit like this... I love it.
Just a hint. Dont use oil for connections use hairspray it dries afterwards thus preventing a hose to come undone.
All of these pumps and tubes are just Rob's desire to get hella hose.
Yeah... With great power comes great fuel responsibility. (Just don't immediately open any lines just moments the engine is shut off or it's water(fuel)wash time!)
Will the hoodie be available in different colors? Black specifically.
13:15 *both chuckling with excitement*
That sweater wouldve been even more dope with some FD type imprints in the back with more Japanese imprints on the sleeve cause JDM u know BUT thats just me u know
Is rob the Sloppy Mechanics version for rotary's??? 0.0
Try rubbing alcohol on rubber hoses. It makes them super slick and leaves nothing behind that needs cleaned afterward.
Rob has discovered the power of city water pressure in his car
Rob jerry-rig an atomizer onto that hose, it will mist your garage and make for a nice humidifier.
Hey Rob Dahm I love the 26B 4 Rotor hoodie man. Oh and I saw your brothers in a McLaren 12C in StreetSpeed717 video the other day and Autovlog video too. Lol.
If you put the hoses in hot water for a bit they go right on to those AN fittings without oil
Gasoline contains 13.0 kWh/kg, so a stream of 1kg/s is equal to a power 13*3600 -> 46.8MW. Assuming 20% efficiency of the engine that's about 10MW.
That Beavis and Butthead laughter
It looked like the line was leaking when you guys were playing around with it
Love the 26b shirts gonna get one in black if you got em got a 85 rx7 with a 12a with a half bridge
Loving this many uploads great content keep up the great work
Two grown men getting giddy over a fuel pump like computer science college freshmen.
Don't change, please.
Love watching your videos. But if you want to get close to 1400hp out of that surge tank you need a much larger feed. 8an can't flow enough. You need to up that to the same ORB fitting which looks like a 10an ORB on top of the surge tank
Ahura Mazda the highest spirit of worship, and everyone was thinking you were a Star Trek Nerd.
Rob, you keep amazing me how truly capable you are of making the 3 rotor a bigger mess with literaly any kind of work you do on it... I beg you to reframe from doing any work on the 4-rotor yourself.
"So you're gonna be wearing, what is, ultimately the most insane Mazda ever built."
Now that is how you advertise merchandise.
so how exactly did you plan on getting all the water back out of the lines and surge tank?
our thicc boi robbi darn cant even spare a little fuel?
I mean do you really want to piss fuel all over the trunk and garage? XD
Flush it with fuel over and over again ?
@@brianchen3964 its possible to not spray fuel everywhere, why did you get 6 upvotes for that
The top unscrews on the surge tank, like he showed last video. He can just pull the pump holder, grab the canister and then tip the water out. As for the lines, it's just 2 vertical tunes, they will just gravity feed back to the surge tank, don't see the issue.
me when people at work take to damn long in the bathrooms XD
Rob: gives detailed description of murdering the camera man.
camera man: *nervous laughter*
i guess you can use this as a demo to show people how much you NUTT when driving your car :)
Hope the main line fuel flow is not to much, for the return line to handle at idle.
When no fuel is used everything goes back through the return, if it can not, the fuel pressure goes up and the engine could drown in fuel at idle.
The fuel pressure regulator won't let that happen. All it will do is create back pressure the pumps will have to work against.
Rob have you contemplated using a fuel cooler, the amount of hot fuel that will be returned from your engine unused will soon bump up your fuel temps and mess with the running of the car if you don’t have fuel temp correction etc
And thank you for providing that laugh once more it has been lacking of late
I'd much rather listen to a CZcamsr plug their own merch a million times than plug dollar shave club 😂
I think the 787B was the most insane mazda ever built tbh 👀
Totally professional install
Rod, FYI, brass fittings into aluminum is not a good idea. They WILL corrode together in a couple years.
the fact he just ran water through them, ahah try a couple of days
I warm up lines to put them on. I feel like oil would make it easier to come off.
Rob have you thought about using that mechanical style pump that works off your oil pump? The one that the other 4 rotor guy uses?
Thats actually really interesting
When Rob finally makes merch to pay for the 4 rotor but it's 2 years late.
Tell your screen printer to use higher quality sweatshirts Dahg. Love you.
"I do not screw around with fuel lines"
Proceeds to screw in a fuel line 💀
Bring on the Dyno !!!!!!!
Rob, aren’t you going to have the hoses crimped to prevent them from flying off from the pressure at heavy load?
probably a stupid question but you cant mount the surge tank sideways at all huh? i would expect it to ALWAYS be topped off with fuel but if you drain it quickly enough it will introduce airbubbles into the line im sure.
Ahura is the name of a restaurant in India. We bikers often ride there on weekends. Search "Ride to Ahura" I'm sure you'll get it.
I just saw an RX7 squirt...
I think I did too
so thats how daddy dahm 'spreads' his love...
i hope your gonna be using a full fire suit next time you take this to the track
Thats a small garden hose, but the motor won't be using all of that fuel. Guessing a good portion of that will be coming back via the return
New shirt idea!!!
"You wanna die today? - Dahm "
I mean this is the most positive way.... Please redo your wiring professionally. The way it is now will get your car burned down.
12:55 Rob realizing how much money hes gonna be spending on gas
i keep thinking of beavis and butthead when you both laugh at dumb stuff lol
So next 4rotor rush build marathon will be by the next 2weeks until sema?
13:35 *after NNN ends*
Hey use break clean instead of oil works wonders and then evaporates
Hahaha omg youre gonna have to buy that wire xD had me crying dude legit xD
that was very cool
At 12:54 you can see it's leaking, hope you noticed that already!
Soooo now your going to be fighting water being in your pre mixed fuel that needs to be precise if not it could fuck your rotary....riiiighttt very nice
Rob, just a heads up! Files only work in one direction. Pulling back will just dull the file
Never use thread tape on fuel components. Never use water to test a pump. Don't use oil to press fit fuel line.
Need that hoodie!
