I made a Stupidly fast Lego vacuum engine. (I should wear safety glasses.)

- So I made a vacuum engine and WOW did it work!
The video is less polished so that I can show it off to you guys in the moment instead of it taking forever. I hope you enjoy.
:)
I do other LEGO stuff too and that’s on my channel, go check it out if you liked this.
Also I recommend using clear tape for the valve because with tape the valve can’t pull apart but with glue the legos still can
That is a good idea. I will have try it
1:29 nice motorcycle engine lol
Very nice design, I like the use of counterweights to balance out the engine. When I did my runs on my really fast engines, they shook my entire bedroom and were incredibly loud.
Thanks so much. It still is incredibly loud though. I wish the counter balance was better weighted, so it shook less.
Hey kfplus, i wanted to know when you are going to upload a new video.
when aRE YOU GOING TO UPLOAD NEXT?
It sounds like an old porsche lol. Can you please make instructions?? i want to experience the engine note as well haha
imagen 5 of them they will sound amazing and it will sound like a mustang
VTEC kicked in
Thanks so much I used your idea for the throttle and that’s crazy fast!
That is some incredible efficiency right there!
dammm now thats speed
Oh yeah!
Sounds like a real engine!
Like it!
I made my own but the simpler version..
Oh dang, that's cool! What did you change to make it simpler?
@@somebuilds I made this one :
ruclips.net/video/-hrkgNmTA-E/видео.html
I also made my own 2 speed transmission for it!
@@somebuilds actually, I recreated it to this one.

Nice work. I approve!
Dude, nice!
really good video enjoyed it alot, nice design im trying to build my own design so im taking some inspiration.
Thats crazy af, subscribed! (225 subscriber)
What a build!
Thanks!
Nice engine
i would recommend putting a lego rubber tire around the top of the vaccuum cleaner bc it would deff suck less false air ;) overal its sounds super good
I’m very interested in how you got your engine so smooth! Since it’s so fast
I think it has to come from the straight walls on either side, but honestly, I have no idea. The last one I made, was no where near this smooth, and it was practically the same design.
Very nice! 👍
Thank you. :)
Nice, you should also try to make a turbine, its usually faster and it sounds incredible
Hey man! Nice vid! did you turn your vacuum to sucking in or blowing out?
Try to add a tire between vacuum and engine. It seals all holes and it makes a lot of difference.
that’s cool, normally I do that. it definitely adds more power
Bro tjat was so cool
no hot glue. but instead, good old bluetac lad.
That’s scary
Its cool souded like muscle car bro keep it working do a i4 vtec bro plss bro
when lego bricks turns into a V8 engine
Muy rapido, que bueno!
Gracias
Niiice
do a torture test on it meaing put stuff in valve while its running and hold it at full throttle
Dude that’s definitely 4000+ rpm
(The higher the frequency of the LVE the more rpm)
Oh dang, I thought it was somewhere around that.
If you put a tire on the hose it creates a better seal so less air leakage
yeah! I just couldn't find one for this demo.
Great video i built mine a little to well i got it up to 12,000 RPM to the point where the piston rod cracked 2 times and the engine exploded
Oh dang that’s amazing
1:31
I heard that engine suddenly start accelerating again, and that is a telltale sign of your valve coming apart.
It’s happened to my engine, but yours didn’t end in catastrophic failure.
Best course of action is super gluing the valve pieces together to prevent that from happening.
Gonna post a video on exactly what happened with mine, you will see what I mean.
I hear the sound! That’s really interesting. The valve was the thing to break which is interesting. Do you know why it accelerates before the valve breaks?
@@somebuilds The valve pulls itself apart, possibly allowing the vacuum to pull harder as the gap in the valve increases, thus generating slightly higher rpm before completely separating
What does pulling the lever thing do inside? And how does it take the energy from the vacuum I taking air and turn it into... Turning lol
Do you mean the blue lever I push down? That is the throttle limiter. Pushing it down opens a little door that allows more air to flow through. The greater airflow means more power.
@@somebuilds Gotcha, that makes a lot more sense lol. How does it take that energy though? Some sort of reverse fan?
No, that not what is being used here.
The way it works is that there is a piston (like you would see in a car engine), and the suction from the vacuum pulls the piston up. It is connected to a shaft at the bottom so that as it moves up and down it turns the shaft. At the same time, a valve that let the air into where the piston was, closes. The big wheel keeps the engine spinning for a bit (due to the stored inertia) and then the valve opens and air can be sucked in again making the piston go up repeating the cycle.
Here is a video, since words are very confusing. ruclips.net/video/UJenP_o6KOc/видео.html
A reverse fan would most likely be a turbine of some sort; people make engines with them, and they go much faster.

Hope that helps! :)
Use pvc pipe glue it’s so strong and I can not get one to blow up with it
Bro your engines idle speed is as fast as my engines full throttle speed and you have a heavier flywheel
mine olso went that fast!
can i find the instructions for this anywhere?
Where can I buy the parts for this
Bricklink I would imagine.
I hope u still read comments on your old videos but pleaaaaaasssse make a tutorial
Use La Gotita
Is not a stupid engine, many people can't make this cool engine
how is your idle my full throttle.
have you tried using a smaller or smoother flywheel? it might slightly increase performance because bigger flywheels and the tires you have on your flywheel can create more aerodynamic drag
Ooh yeah, that’s true. I chose this one because it was what I had
That's really fast like 1000rpm
Thanks man
@@somebuilds that’s definitely about 4500 rpm. 1000 rpm sounds like a diesel.
can ytou make a tutorial?
kf+ lego mastery ??
Yep
i made a lego engine work with gas but it melted i used a real cdi and sparkplug
please can u do a tutorial
how much rpm? i bet it only does like 600rpm to 2200rpm you can kinda count how much rpm its doing so i bet it doesnt run the fast
but im pissed that u got a lve to work and i still havent gotten a lve to have eny torque or do more then 400 rpm.
have a nice day! :).
sorry to hear that, thanks though
Vrruuum
this is a year late, but use super glue rather than hot glue 🤣 i havent built one of my own engines im looking for tutorials that have an throttle but super glue is wayyyy better than hot glue
I agree. I was using hot glue bc I didn’t want to leave my Lego like this permanently. I wanted to be able to change it. But yeah super glue would be way better
normalest vacuum in albania
In that case Albania must be on fire!

That’s not fast at all
