Okay so, I am a car person and will tell you... I fell in love with that revving sound and the shifting... THIS IS A TRUE WORK OF ART AND GOOD USE OF LEGOS!!!

That engine sounded so good. Sounds like a four wheeler engine. I would suggest you to use the Lego gear selectors if you know what I mean so the gears don’t slide out. Otherwise it was awesome

The madlad actually did it! I cannot believe that a youtuber actually listened to one of my ideas!

This is so cool! Reminds me of when I used to play around with lego vacuum engines years ago back when I lived with my parents, I have a few videos on my channel if you're curious. I had a similar output load simulator and everything! I used a centrifugal clutch to link the engine to the output in one of my videos, which helped to free up my hands lol I used this twin cylinder config in several of my designs. It always worked quite well, in a 2x2 and 4x4 config, 3 stud stroke. Never thought to use the smooth wall pieces and olive oil though, that probably makes all the difference! I also played with a funky cylinder configuration that I called an "M" configuration (stands for mirror) that iterated off of this simple design. Essentially, the twin cylinder is iterated sideways as many times as you want. This results in multiple crankshafts that are connected with either a gear train or chain, and a single manifold that is quite compact, which helps to minimize leaks. This design theoretically allows for any number of cylinders (up to a certain point), because you can set any crank offset that you like, as long as the gears support the offset angle you want. I tried a 4 cylinder with 2x2 pistons, but my engines weren't nearly as well designed as yours, so the engine wasn't that much more powerful than a 2x2 twin, it had a fair bit more torque though. It self started, which was nice. You should try it out and see how it goes! I think it has some potential with your superior design. The M design offers a relatively small manifold size compared to the rest of the engine, minimizing leak losses.

at first, I thought it would be one of those cheap lego engines. That SOUNDS AMAZING!

Stuff like this will get you over 1k faster than you know. Excellent contents my dude, just discovered you this morning and subbed because this is awesome, and makes me want to go out and get some lego technic to take a crack at it myself

WOW! That scene at 7:47 sounds so awesome!! Please do a instruction video or post some detailed pics that show how to build it! Most awesome lego engine I´ve ever seen😱

This is so cool LOvE the engine design and Transmission!

This video is amazing i always enjoy your interesting lego KZfaq video builds

Literally unreal how amazing this is

Yaaayyy! A full assembly!! I’m editing my video right now!!!

This is just dope I know this is a year old but if you could honestly do this forever this is like a dream come true I would have loved this as a kid!

Your an awesome guy, keep it up big man💪

Great video!

Very cool!

Sweet man! That thing is friggin cool!

that is cool!

this is such a cool way to demonstrate a manual transmission system!

500 subs you say? lets go for 1000!!!

bruh not even 2 months into "next year" and you're almost to 800subs thats awesome.

Man this engine sounds so cool

Can you do a full tutorial for both of those before you rip them apart lol

Amazing

Now thats sick

love the new intro

this is way better than what I can make its awesome

amazing

this man has all the time in the world, also make a pdf instrcution on the vacuum engine and carb for it

Your a genius

This is cool as hell

6:49 when your engine shakes so much it downshifts

Now you have nearly 10k my guy keep going 😅❤️

You are a genius

Awesome build, would love to see a gated shifter for the transmission. Otherwise this is super cool

it's amazing how strong that engine is

I have no idea how this got into my recommendations but I like it

Been watching your videos on tik tok didn’t know you had a youtube till I recognized the name I’ll follow and subs rn

Amazing work!👍 I recently made my first 1piston lego engine but the clutch I made isn’t that efficient could you share your clutch design? Thanks

that is one of the best sounding lego engines ever

Noice intro

Htf are Lego plastic pieces strong enough to hold up qndnot blow up especially without oil

Did you know that Lego makes their own pistons they are smaller but your big pistons are still good👍👍👍👏

Would this work in outer sqce without any fuel? Seeing as space is supposed to be a vacuume

Hey man love your vids I just wanted to know if you can make a tutorial on the engine

Cool 👍

That clutch is how they actually do it in real cars. Did you know that? Really good vid, by the way :)

That sounds better than most cars😂

Wow

Your mechanism to regulate speed is more a "throttle body" than a carb because it doesn't mix air and fuel, rather just meters flow.... I'm realizing I'm sounding picky, don't mean to. regardless, dude these are the best Lego vacuum engines I've seen on youtube in a long time!

Sounds better then the new dodge.

I sounds like a quad that is sick kid

holy shit thats the most AWESOME THING IVE EVER SEEN OR HEAD IN MY ENTIRE LIFE

Ur my favorite utuber

I have a manual two speed built but the shifter actually stays. Although you have to move the whole thing instead of just moving it forward or back. How did you make the shifter?

BRO YOUR CAR SOUND IS BETTER THAN CAR SOUND🥶🥶🥶

sounds like real

Thanks so much for the shout out. And what do you use to edit.

Hey can you make a tutorial how to make the pedal on the clutch please?

Engineer : lego is not realistic Lego people :

THE SOUND

This engine does have a pretty large bore and short stroke, which does make sense for a vacuum engine

Honestly you should have a flywheel on the drive shaft it’ll just make it run smoother and not as clunky

Sorry to hear about the broken gear.... my opposed piston lve cracked 2 of my 4 16 tooth gears.. 😡

You should use a functions motor as a starter which is what i did but it made the output a little lower

I made something simillar, a vacuum engine connected to a compact clutch and a 2+N gearbox

2:40 that clutch is pretty genius!

what you got there is a non syncro non constant mesh gear box aint got no syncros and the gears are not constantly meshing reminds me of a "3 speed" transmission i tried to make in scrap mechanic and i still aint got a working transmissions yet in that game i'd love to make something like this but i only got 4 gears (2 8T and 2 12? 16? idk but they are the really small kind so yeahhh ima have fun making a 3 speed with that and also some of the slightly wierd kind that have 4 lugs

Wow thats really cool. Next step is to build a lego car that runs on petrol😂

you should try using 2 vacuums, each one connecting to a piston. I think with only one its more stressed and its losing power because of the double friction but same vacuum power. Pretty cool tho, sounds better than most real cars lmao.

Will more gears help with fast acceleration? IDK how Gear shifters work

sounds like a harley davidson

Can you please make a tutorial for that clutch???

yoo I would totally buy this from you lol

Lolll sounds like grandpa is pulling up

What the hell. How did he-

dude literally as i got my lego out i thought of of using 4 by 6 also i havent so far seen anyone use like duct tape instead of the tall walls has somebody tried it and it was to grippy???

did you lubricate the pistons? it’s just that my pistons don’t spin as smoothly as yours

if u have a electric vacumer try to mkae a car that can pul the vacum to make the car go without any limits

Hey, lego person here. How did you get your pieces and wherls and stuff?

That engine is a beast, what's your secret?

Can you make clutch+gears bos tuto pls

i dare you to try to rev match up shift and down shift that thing

You should try an inline 4 😂

Does there exist a tutorial for this clutch?

Could you make a tutorial?

Can you make a vid where you let it run with an high performance piston

What happens if you floor it

That’s very impressive. I’ve made a Lego steam engine on my a channel if your interested

Where can I even find there parts😭

2:27 Please read the tutorial how you made this lever with two wheels

I wanna make one so bad!

Y do i feel like i can actually drive this? 😂😂😂😂

Full rev from 4 to 1

wow it sounds great. you should try to make a turbocharger for it

please turorial fo this clutch

This prolly makes 0.5hp and 0.7lb of torque which is a lot of power for a lve

that sounds like a car

Do a sequetial gearbox for that

What the heck that sounds like a real engine

What if you put in your new transmission it would be smoother
