Kfplus, I’ve been making loads of engines now and I’ve found that a 2 cylinder 4x4 is the fastest for me. The single cylinders I have built are way slower with no throttle response. How do you make your singles so quick?
I made the exact same one cylinder as he did and it runs the exact same. Try experimenting with his mechanism and make sure to lubricate the parts for best results
I built it just now and it sounds amazing and is really fast. I didn't want to glue the piston head and I accidentally started my vacuum on full power and it sucked the head right of 🤣 I needed to substitute some critical parts since I didn't have them available but it still runs incredibly smooth. Really nice work 👍
Thats a signature "feature" of LVEs.. they are loud and vibrate a lot. I can shake my entire house with just one fast engine, its crazy. Maybe I will design a counterweight for the crankshaft!
@@3rd_ACC did you have any trouble with it being stiff? i cant tell if its my flywheel being small or the crank is rubbing against the conrods. with the vacuum attatched nothing happens despite how fast i spin it
Amazing video man thanks so much I got it to work after you said the Half crank had to be 90 degrees ahead of the other piece, very important and it was so satisfying after I fixed it
This works so well even though I improvised so much even if you don't have the parts it still works cant wait to see new videos and a tutorial with a shifter.
Little tip to make your vaccum engine significantly faster instead of using the 1x1 hole on both sides for the intake. Just use it on one side, and then you will get a lot more airflow into your cylinder, which will give you higher performance. I hope this helps :)
I followed every step , watched it more than once, and checked over everything I don’t understand how it’s not running Edit: just kidding! I have been messing with it for the past hour and now it runs great
I had all parts at home and it works perfectly thank you ❤. It just took me 5 hours to find them all in all my Lego chests. 😂 Now mine is even pretty much all red 🔴
idk why and who and what and when but i somehow got the idea to search for lego motor and found this part of the lego community, want to build one very soon if i have the pieces, great video!
Can you make one using technical Legos? They are considerably more stable and offer much more functions than conventional ones which I think would be interesting to see. Anyways, your engine worked really well thx 😁
THANK YOU VERY MUCH i builded it and it sounds like beast and yeah i didnt glue my parts and i did max throttle and the engine just breaked but its easy to fix
You can very easily replace that piece for a 2 stud long one, you may have to adjust the length of the valve connecting rod but it would definitely work. My first LVE on youtube utilized that crank setup and it worked just fine.
Can you please make a video explaining not how to build a lego vacuum engine, but the parts and how it works. I really want to build a lego engine but I just don’t think I’m understanding everything. I know this is a tutorial but I would rather build my own design
You have a valid point my friend. I will be doing an in-depth video about how an LVE works along with how to calculate its displacement in cc. Stay tuned!
i made a similar engine but when i get closer to 6000 the piston is moving up and down so fast that it rips it off the crankshaft and it shoots through the top of the engine
pretty good tutorial! i would love to see something like this but a tutorial of the rotary valve lve. it seemed really smooth and i want to know how to make it
Great video i modded the engine with a bigger and wider piston and cylinder with the valve and intake the same as this video after I built it and i got it up to 12,000 RPM and the piston rod cracked 2 times on the crank end i had to wear ear protection because it was as loud as a sport car with no muffler it was insane also my cylinder wasn’t see through because it decreases power if you make the cylinder nontransparent then it will increase power
@@KFPlusLegoMastery I’ll post it once I fix my vacuum engines cracked cylinder, when I built it the way you did no mods it could withstand the high RPM no problem after I modded it, it couldn’t withstand the high RPM every time, causing cylinder and crank failures it only hits 11 to 12,000 RPM after putting a lot of oil in the directly into the cylinder because I saw a video from someone who pushed a LEGO engine to 12k RPM and it blew up that’s how I learned the max speed for legos
Just made one of my own, and I gotta say, I'm impressed. I don't have a wheel that big but I got one that works, I also tweaked the throttle a little and I noticed slight improvement. Cheers! Side note: how do you keep your vacuum on the engine? Mine is constantly slipping off, also whats the song playing in the background towards the end?
@@wezeledelman761 I did, but it still managed to slip off. It's not a super big issue as I can just hold it there, but enough to where it's a little annoying. The tire works great as a seal tho
Hey this might sound like a big favor but can someone help me track down these pieces or at least point me in the right direction? Really want to make one of my own after seeing this video and all these comments.
Yo this is so cool and i just built it and then i made a v2 of your design for better sucktion mount and i also remade the piston head so it wont pop while giving full throttle so yeah thx for ''tut vid''
Trying to make it but don't have the right pieces could you tell me what the small orange thing at the too left if the parts part is and same with the wheel
@@KFPlusLegoMastery what would happen? Sorry I’m not good with engines…. Anyways one question is that is there a substitute for the two grey pieces that have two crosses in them. They are thin and rounded and used for the piston to keep it in place
@@acast7 To answer your question, yes. You can substitute those two pieces with 4 of the half-stud axle bushings (they’re usually yellow or light grey color). Works exactly the same- Good question!
Hey I’ve made the whole engine but I need help with putting the vacuum on and getting it to spin with the vacuum and to get to consistently spin can you please post a video on your tick-tock on your RUclips telling us how to get it to start spinning
Hi everyone, I just finished building this awesome engine! But I am struggling to get it to start. Does the vacuum have to seal really well against the intake? Or any other tips to help get it started!! Thanks 🙏
im going to test this tomorrow if i have the parts bc my mom and i agreed to sell my legos but now im sad we sold them. and im excited bc i have a fucking powerful vacuum so im gonna test this things limits 😂
Kfplus, I know it’s been a year since you made this tut but is there a different part I can use instead of the beige thing you called the crank? I don’t have one and i really need to make my engine work. Hope you reply 😊
this does not work at all I hook a vacuum up to it and it just pulls the valve up and doesn’t go down and it breaks the whole accelerator thing due to suction??
my engine is a mystery, is just doesn't work.. i did the valve timing right and it keeps getting stuck when i try to run it.. it is the vacuum cleaner or what it can be?
Mine just does'nt work. I try to spin the wheel and the whole mechanism doesn't spin, it just stops. If not fluent, its not flowing, and its all just seized up. I thought it would work :(
@@taylor842 well by the sound it went faster than the tiktok one i used 2 motorcycle tires and more car tires so like a very heavy fly wheel and i have powerful dyson tower vacuum without the pipe so its compact

Made my first one tonight! Had to improvise a decent amount due to the lack of some pieces but eventually she roared to life! Awesome video, thanks.

Hey man! Since u lard had a startup can u tell if you turned to vacuum to suck or. to blow?
@@SubfordimondsIt is supposed to suck
Kfplus, I’ve been making loads of engines now and I’ve found that a 2 cylinder 4x4 is the fastest for me. The single cylinders I have built are way slower with no throttle response. How do you make your singles so quick?
reduce the piston crank to 2x1 and valve crank to 1.5 and a smaller flywheel i once made one and it ran on a car vacuum
@@redstonegod296 2 cylinders can run without a flywheel and piston stroke is 3stud valve is 1.5 stud i think
@@niteh4wkk926 make the crank 1.5 instead of 3’s. Less torque but also less piston speed meaning more speed
dam what language ya speakin tf

Glad to see you had success :) I have an idea for an indestructible piston that will require no glue to stay together, so stick around!

@@3rd_ACCtry again

Amazing video man thanks so much I got it to work after you said the Half crank had to be 90 degrees ahead of the other piece, very important and it was so satisfying after I fixed it
OMG this is so cool. It took really long to find the bricks but it works! thanks for tutorial
Where didu get all the parts for the whole build
I came here from the first video of this playlist, and you've grown so much! In views and in age, I hope you make it in life man
I just started making engines last night after seeing this channel it’s been great and was wondering how you measure the rpm of the engine?
Look up tachometer on amazon
I use a hand held laser tachometer, you can find them on Amazon for $20-$30
making my first engine now thanks for inspiring me

Hey could you please give me some pointers. I have no clue what I did wrong but my motor won't work at all
I just made the world fastest 3 cylinder SOHC with my new valve design!! I will upload Saturday!
I followed every step , watched it more than once, and checked over everything
I don’t understand how it’s not running
Edit: just kidding! I have been messing with it for the past hour and now it runs great
What vacuum do I use and how do I connect it? Also, great tutorial.
I made mine not to long ago it isn’t so loud but it’s really strong it made my flywheel blow up
I had all parts at home and it works perfectly thank you ❤. It just took me 5 hours to find them all in all my Lego chests. 😂 Now mine is even pretty much all red 🔴
same😂
You know what else is moving right along? This channel😏❤️😁
This is gonna be epic
Your engines are awesome! You inspired me to build one of my own and I am designing another that will be the first of its kind!
Just built mine. Sounds amazing, and pretty reliable if you glue the piston and valve.
Mine didnt even run altought nothing was wrong
@@veikko3426 same for me I spend 3 hours building it and it doesn’t work
@@veikko3426 ok it works now I used a different wheel
What glue do you use?
@@Drewskii55 I used Tamiya Cement. Super glue would probably work just as well.
just made my own and it works brilliantly :)
Yo I built this and it works AMAZINGLY 👏 thank you SO much!
I did the I followed the tutorial but it didn't run at 6000 rpm
idk why and who and what and when but i somehow got the idea to search for lego motor and found this part of the lego community, want to build one very soon if i have the pieces, great video!
Can you make one using technical Legos? They are considerably more stable and offer much more functions than conventional ones which I think would be interesting to see. Anyways, your engine worked really well thx 😁
well technic beams have more wholes and gaps for air to seek through but it would be more interesting
I think the idea was to make an engine with the blocks that most people have
Спасибо вам огромное это лутший двигатель у меня все получилось 🔥👍❤️
Бро ты склеевал пластину 4×4 с поршнем подскажи пожалуйста😢
For the valve and crank can you use a 1 by 2 axle connector like in the previous piston
Yes I did that
THANK YOU VERY MUCH i builded it and it sounds like beast and yeah i didnt glue my parts and i did max throttle and the engine just breaked but its easy to fix
I made the engine exactly, it seems like yours spins way easier. I put a strong vacuum to it but it just won’t run, so you know why? Any tips?
your vaccum might be too strong
im having the exact same issue. i built mine exactly like his, but it wont work. it wont even crank.
Sure you used correct colour pins?
thank you so much for putting all the parts at the start i was able to find all of them and make a smooth running 1 cylinder engine!
Should try to make some engined without the small motor crank (yellow piece crank for valve) I don't have them, and finding those isn't easy
you dnt need them yo can use some spacers and 2 hole little pieces you have to get creative but that will work
You can very easily replace that piece for a 2 stud long one, you may have to adjust the length of the valve connecting rod but it would definitely work. My first LVE on youtube utilized that crank setup and it worked just fine.
Can someone help me. Me engine is not running unless I have full throttle

try gluing all non moving componits
bro lego needs to make this a set fr
pretty good tutorial! i would love to see something like this but a tutorial of the rotary valve lve. it seemed really smooth and i want to know how to make it
I might make one sometime soon
Mine sucks up the valve not the piston.
Do you got a link on where to get the extra parts like the orange piece on the piston or the yellow half cranks?
That is a verry good engine..... Let's build a inline 6 engine out of this with a gearbox and just One flywheel
Great video i modded the engine with a bigger and wider piston and cylinder with the valve and intake the same as this video after I built it and i got it up to 12,000 RPM and the piston rod cracked 2 times on the crank end i had to wear ear protection because it was as loud as a sport car with no muffler it was insane also my cylinder wasn’t see through because it decreases power if you make the cylinder nontransparent then it will increase power

scariest things on earth

The piston popping is just a quick scare
The real threat to life is when the valve comes apart and yeets the throttle block off the engine
I had a lego Enigine then it broke I got sad and didn’t want to rebuild it this vid made me want to

@AlvinGZY if you watch the first part of the video he has the engine fully dismantled and all the parts are there
I need to see what the pieces name is
Well when my engines don’t run I put vegetable oil or any safe plastic oil. If not, try making sure there is no air gaps.
You have to use the kragle.
Best comment by far
I even put olive oil in it and its just dont wanna start😭
Edit: it started and 10 second later blew up
Thank you so much for Thie Tutorial
im going to test this tomorrow if i have the parts bc my mom and i agreed to sell my legos but now im sad we sold them. and im excited bc i have a fucking powerful vacuum so im gonna test this things limits 😂
I built it and it works well but are there any attachments you can make to add to it?
You can add thinks like a transmission, a starter, maybe even an exhaust manifold and pipe for cool sound!
Could you list the parts or make a plan on the site that generate one
I gonna supercharger it
where do i get parts to build this?
I built mine exactly the same idk if it’s my vacuum but it won’t work for me
Thank you really much! I made myself and it Works really well🎉!! Thank you (again)
It works so well thanks you a lot for this video!
Didnt expect sneedposting in the lego vacuum engine community
Can turn these into drag cars by using small co2 tanks instead of vacuum and let it launch 😈 by holding down throttle with rubber band
can make a supercharger and hook it up to the crank & the engine and it’ll keep going by itself
I did make it myself, but I needed to adjust the throttlebody a little bit (don't got all the right parts) but it works
Kfplus, I know it’s been a year since you made this tut but is there a different part I can use instead of the beige thing you called the crank? I don’t have one and i really need to make my engine work. Hope you reply 😊
same here
If somebody dont have the thing for the piston. You can improvise it still works well maybe not as fast but still very fast
Try gearing it down a lot so it spins at a similar speed to a Lego motor
I have all the same peices I’ve triple checked to make sure everything is right have it timed right it just won’t run I don’t know why
Gonna try this out
This is awesome
took 4 hours to build because i had to make a few pieces i didnt have but turned out amazing
Thank you so much my engine is very powerful
this does not work at all I hook a vacuum up to it and it just pulls the valve up and doesn’t go down and it breaks the whole accelerator thing due to suction??
I was able to make one and it works I had to make some of the lego pieces that I dident have out of other Legos but it still works ❤👍
Everything works for me, but the head of the piston presses to the top, what should I do?????
I was just wondering why did you use a 1x2 half beam for the other crankshaft instead of the tan piece?
my engine is a mystery, is just doesn't work.. i did the valve timing right and it keeps getting stuck when i try to run it.. it is the vacuum cleaner or what it can be?
