15,000 RPM - LEGO vacuum engine | NEW WORLD RECORD!

This weekend I achieved a new world record, just shy of 15,000 RPM with a Lego engine, no doubt it got up there at one point but my tachometer is too slow. Thankfully it didnt blow up but that’s because I only let it go for a few seconds. There was no friction damaged surprisingly so i didnt bother adding that into the vid but let me know if i should do a durability test.

Instructions are free when this video and thelast one his 10k likes combined.

I’ve been working on this for a long time so y’all better not say I copied him😅

Nice one! The glue is a little bit cheat😏
But I will make a 3.0 version soon!

Dude you're doing this correctly! The way to achieve high rpm is air inlet at the periphery and exhaust out the side. That's how we achieved high rpm when we built our turbines in the 1990s. The tri-rotor you used it what it's all about. You know you've achieved LEGO Nirvana when you start shearing knobs off your lego. Well done man. You've figured it out!

[tunk_ton]

it didn't look that scary on the video but it probably was hella scary in the moment. i would suggest a bent acrylic sheet over the engine as well as one for just cover to stay behind and go full beans!

Important Thing To Remember To Make A Very High RPM Lego Engine:

Lubricant And “Glue…?” 😅

It Reached Almost 15k RPM, Thats Fast 😮

[secretmanPFD]

the glue is a bit cheeky - but the end result is very satisfying, so we'll let it slide

[Sierra-]

naturally, I wanna see it go full throttle. lol
Keep up the good stuff man

[Lgwasherfan]

Yay its V2 unlike explosion from other

[johnstewart]

This is super awesome😁 i subscribed to watch the progress.

[fskartingco.]

Looks and sounds great, I would really like to see what this thing can do in the future. I saw another comment where you said you didn’t open the throttle more because it was making some scary vibrations, maybe some way to balance the rotor would be good?

[nicholasgagliano]

Great job and fantastic build, I can’t wait for you to take this even further if you can !

[Legostuffidk]

This is a really cool turbine, but it isn't the world record. I don't wanna burst your bubble but I've seen a few hit 20k rpm in the tble server without using glue. This is a really cool turbine tho

[ImNew-bq]

i was surprised when you said the blades were going over 100 MPH (4:01)

[HydroWorldOutlookPrimary]

0:41 Well, it’s not the only way. You could also 3D print a rotor designed to spin at that speed.

[Wopps]

Yo ! I have an idea... a project ! Make a realistic car with a turbo, an engine etc... PLEASE !

[David_Mash]

You dont need glue, you need to modify your design to remain legal

[paradiselost]

remember the air here is still limited in the speed it can achieve... theres certain basic physics governing air speeds due to pressure differentials.

if one asked this turbine to do actual work, at max efficiency it would run at half the speed of the air flow...

and despite how it seems... the air is expanding, as it enters the lower pressure...
probably get slightly better results running backwards to this... intake in the center. like a normal centrifugal impeller... youre asking the air to flow backwards to how it wants to flow here. it wants to fling out, the air mass entering from the center... its that incoming airmass that does the work.

its odd. i have one of them little 250s that happily revs at 18K... the tacho doesnt even register below 4K.
yet i jump on a lathe and just 500RPM seems stupid fast...

[ConvictJ]

Cool but lacks the robustness of the other ones. That might just be a consequence of having the turbine axle be in the same direction as the vacuum. Silly question but what happens if you use the other hole for the throttle and move the vacuum to where the throttle currently is?

[takeneye]

This reminds me of making spin tops outta those Bucky ball magnets hanging them by one off metal above and hitting em with an air can. Things had to be going like 3k before they bust into 150 balls flying everywhere haha

[Elhamburitto]

Like a real turbo it probably needed constant lubrication while spinning at such speeds

[AArch_Gamer]

Reminds me of the A320neo engines spooling up in MSFS
