3:23 My favourite bit by far😂😂😂
Make a supercharger next
@@NorthTo60A supercharger doesn’t do anything on a LVE. It can’t force more air into it. And even if, the resistance will limit the power output and the rpm so much, that the engine might even run worse.
LOL
try this again but instead use 2 vacuums on it. one for cylinder 1,2,3 and the other for 4,5,6 as you might be running intoair flow rate issue due to the single vancuum this should improve engine speed and power slightly. down side is you need to make another throttle body for 2nd vacuum
You’re definitely on to something. I think the 6 has a lot more potential, it’s just very impractical to unlock it. I don’t have a second vacuum but I might try to get a compressor into the intake
That’s what I was thinking! Nitrous!! 💨
YEAH, do 6 vaccumes! one for each cylinder.
@@calvinthedestroyer that would be wild
They both are impressive not gonna lie.
This editing is insane. Keep up the good work.
This channel is gonna be huge someday. Remember me then! Good luck man, keep up the good content👍
Bender "REMEMBER ME!"
bro deserves so much more cloute
(Clout)
Nice video brother ❤
Thanks legend👊🏻
Nice!
The editing and filming is extremely good!
J'adore le moment où l'entrée de l'aspiration tombe à 3:23. Incassable
3:22 i know this pain my friend
the vroom vroom sounds are so cool
the lego vacuum engine community needed someone like u
These LVE’s are so cool and clean! I’m working on a Dyno for my LVE car. You deserve way more subs and likes! Great job! Mabe v8 next? 🧐
Both look fantastic and I have to admire what your doing
But it would be interesting to see what would happen if a 2 cylinder had 1/3 of the suction power from the vacuum and the inline 4 had 2/3 with the inline 6 have 3/3 of the suction power.
I wonder which would lift the bottle quickest then as this would balance the air flow side to give a more realistic example as ordinary, the six would require more suction to match the output
Keep up the good work tho, your engines are awesome! 👏👏👏
Definitely a volume of air per second type of problem. I don’t really have a way to limit the vacuum tho
6:30 sounds like a lawnmower!! I love it!!!!
You should try a simpler 2 «cylinder ». That’s generally how I build my engines and I managed to make one that was very fast and torquey, but still pretty smooth and responsive. I used 4x4 pistons (KFPlus « performance piston » design), individual throttle bodies for each «cylinder », a thin 43mm diameter Technic wheel as a flywheel, gears for syncing the valve shaft with the crankshaft like you did, and a slightly different valve design where I used 2x1 Technic bricks put in the « center » of the hole, instead of 2 1x1 on the sides, which can easily be misaligned causing extra friction. I also had a smaller stroke for the valve shaft, using some conventional Technic crank parts used in fake engines. Otherwise, great designs!
this is very cool, dude! Sorry for the lack of views, good luck with everything!
The view will pick up no doubt. Thank you for the support🙌🏻
I have one more question, what is the secret of speed? is that the pistons are 6×4? lubricant? or a powerful vacuum cleaner?
@@sharik1337 the design is very effective and my vacuum is powerful
Would love more dyno runs. Perhaps spinning up a heavy weight like a brake disc from a car would be possible
I kept the disks from the last break job I did. I just have to figure out how to attach it
i way to make it wayyy faster is to add some luberication, like olive oil to the pistons, and valves. that's what i did, and it made the rpm go from 2200, to 4600! But, dang, this is impressive, i barly have the parts to make a 1 piston engine, and l would not have the patients to build for that long, awesome!
I will definitely add that segment in for another vid, there's a few things I cut from this one for time!
Try using tape to cover the gaps (especially on the exhaust manifold) Though it doesn't look as clean, it will increase the torque and RPM as less suction is lost. You could try to put the tape on the inside if aesthetics are a primary concern. Either way that engine is sick as hell!
Haha, I actually had this in the script but cut it for time. I’ll try it for sure tho!
Have you considered using a differential system to adjust the engine timing more fluidly and possibly while the engine is running? You may reach a more ideal 'tune' that way
your channel color scheme is peak
What's the music at around 2:22?
The inline 6 dosent have as much suction per cylinder as the inline 4 does which then during the winch test the inline 4 could rev higher and hold its revs.
Op filming
for your inline 4 breakdown, you had something between the throttle body and pistons to help seal it, what did you use?
It’s just a sticky note that I used as a gasket. Not sure if it actually helps tho, I gotta test that when I get home🙌🏻
Im curios what happens if you take a really strong industrial vacuum
Hello, what would happen if you let the engines run under water ?
I thought your video was very good.👍
I want to try that! Good idea:)
I’m going to assume you glued your valves? I’d imagine with one stud connections like that they would explode at high rpm’s otherwise. I toyed with the idea of trying to make sideways valves to prevent having to glue them but they didn’t quite fit.
The valves in the I-4 are glued but the 6 doesn’t use any glue:) I know what you mean by building them sideways tho, that’s definitely worth some more explanation!
@@jmodsbricks Made a temporary short so you can see (forgive me if this doesn’t work, I’ve never made one before).
czcams.com/users/shortst_G_6MJEgls?si=GuZfkD4lUjmMNRzE
I’ve only made the single piston engines for lack of parts, so the pivot point of the valve was in line with the crankshaft. This probably wouldn’t work well with inlines.
Also I’m amazed your valves don’t enter low earth orbit whenever you throttle that thing if they’re not glued lol. Probably brand new parts.
Also also, I’m equally impressed by the fact that your crankshaft is made up of those loose technic pins. Whenever I tried to use those they would mess up the timing with all the slack they have, especially with that many pistons in a row.
3:23 unbreakable got me dying
Why does your logo look like the hub?
If you time it like a real I6 (like 2 inline 3s mirrored with the pistons moving in pairs) it should have perfect primary and secondary balance.
i think its not as strong since the inline 4 has less pistons than the inline 6. Lets say you are sucking at 40psi, on a inline 4 you will ideally get 10psi on each piston but on a inline 6 you get 6.667psi on each piston which will result in less power. What if you suck harder and theres also the problem of giving each piston balance sucking like a intake/sucking manifold
I can’t even get a one cylinder engine to work so this is incredible
Think smaler
Can u make a tutorial piece by piece please?(for the inline 4)
I have free instructions and parts list on my rebrickabke page:)
you should have done a 2 lb and a 3 lb torque test too because although the i6 is slower, the power from the vaccuum has to go somewhere, and by somewhere i mean more torque than the inline 4
I’m going to do a proper vid torque testing each one and doing the math to actually figure out the HP🙌🏻
bro has my vacuum...
i would like to see one where pisons 1 and 6 are in sync 2 and 5 and then 3 and 4 like a real i6 engine then it might sound a bit more real and be more balanced (i think) edit i saw that you already did lmao
Can you build inline-3 with 3x3 pistons PLS🙏🏼
I think i3 will be next but I don’t know about the piston size yet
surely we make this a purchasable kit. My birthday is coming up... :)
I’m gonna make the instructions free:) just gonna polish them up for people to download
btw those peices you used for crank/cam arent too great, with using pins instead of rigid axles you get alot more play in the crank as a whole
I want to swap the orange crank parts in the i4 to those half liftarms with axle holes but the 6 needs a weird offset between cylinders so that part was the only option.
@@jmodsbricks ohh i didnt know you were doing a non 90 crank
1:51 music name? Very good video too :)
Counting stars by Nature of Things
@@jmodsbricks TY
now add the turbo that is powered by the exhaust and not another vacuum! :)
Have you ever tried a v8?
Can you make a Slant-Six? :)
I’m not familiar with the type but I’ll do some reading:)
@@jmodsbricks not sure it's anything special, I just hear about them all the time. Must of been a favorite amount car guys
Not bad
Make a 3 cylinder and compare it to the 4 cylinder in performance
what about 1-2-3-4-5-6 ?
That would be cool but very unstable. I might give it a try tho!
Inline 12.. we need more pistons
even better is an inline 1 cuz of torque and rpm
“Unbreakable” 😂😂😂
3:25 unbreakable😂😂😂
V8 When?!?!?!???!!???
Try putting your turbo charger on it
*unbreakable* Casualy Equips Sledge Hammer XD jk jk
Flat 8 and 12 when
I’m not sure if it’s really worth it to go bigger than 6, I’m still trying to decide. I’d love to hear what other people think tho, 8 would definitely be the next step
@@jmodsbricks what about a V8 powerd by 2 vacums? If a V8 is buildable
@@Nicklon it’s definitely possible, I’m just not sure it’s practical. Might have to just try it anyway
@@jmodsbricks would be nice and i want to know how it would sound and with 2 vacuums it must have enough power
inline for sounds better
Dude, Legos
Lol look at this 3:23 💀💀💀
the music is obnoxious. Compared to other Lego channels this channel is a downgrade. Work on removing the music for the user experience.
Thanks for being a dick about it👍🏻
