come back😢

2 years passed... congrats on 2.5k!! you reslly desarve it, and even more!

4000 rpm!.😮

You bought the piston from gecko?

Spins wheels a 1 rpm for 3 seconds ...... Burnout 👍

That’s not two stroke❤

Coool

Give us the mechanism ALL OF US NEED IT

😮

I have gave this challenge to almost every lego youtuber. Make a engine without technic pieces.

Illegal! 🚔

Try sealing off the crankcase it will be almost silent but more efficient and faster in my experience with the one working butterfly I've made

Well this is a "Duesie"...

The air intake will only boost performance if you blow into it with something... since it's double acting (2 power strokes per revolution per cylinder), the ideal crank offset would be 90°, that would give you 4 power strokes per revolution and self starting capabilities

Basically handstart now

All these dohc lves work perfectly fine and my dohc v twin just wont :(

make a dump valve dare u

It actually sounds like a drag engine

make tutorial

Pls make more vids

Cool I could probably not make something so cool

I made the first ever blower Lego vacuum power engine that works😂

This sounds like a 4 cilinder civic

Roots not twin screw

Subbed this is tool cool

Ja nawet jak buduje z tutoriali nigdy niedziała nawet po smarowaniu

Tutorial pls

Tutorial?

It's kinda like one of my engines from like or 4 years ago

Hey man! Nice vid! Are u using the sucking in mode for the vacuum or the blowing mode???

First supercharger for a Lego engine was back in 2014 bud

Super cool video, I loved the sound of the engine, plus I'd like some tips on how to get one of those vacuum engines working, mine always have too much friction. Small error, however; at 1:00 you said that the gear on there is a 1:4 ratio. that is a 1:3 ratio, its 8 and 24 teeth which if you divide both by 8 you get 1:3. 1:4 would be 8 and 32 and there are no 32 tooth lego produced gears. there is no way (unfortunately) to produce a 1:4 ratio with only 2 lego gears as of right now, as the smallest lego gears, 8t and 12t, would require a 32t and 48t gear (respectively). Perhaps you misspoke, however I found that a bit bothersome. Super cool video, cool looking dragster tho, cant wait to see more!

It is a 2 stroke cuz its a butterfly engine

jet engine the third design

i love your videos : D

Im trying to make one so i have a few questions 1what kind on blades do it have 2what size for thorratal

Great build!

Technically it is a 2 stroke because it’s a butterfly engine

Get a bigger hole for the intake and a bigger propeller whit 3 blades

wait u didnt know u can just get it to run with more airflow? damn mine is a bit more ahead in tech then i ran a 4 brick gap of exhaust (the intake is the one u called exhaust because it sucks not blows) and ran what u had on intake

Why did u stop uploading

How much load can this thing take

Any tips as to how to make it that fast ?

tutorial?

How do you get that sound

Can you please do a tutorial for how you make it

Strap a ridgid brushless vaccum on there and let it be freeeee!

Make a tutorial
