Hi! I didn't have 8 of those small cylinders so i builded a 4 cylinder version. It worked very nicely and i got 1240 rpm without modding anything. Cool engine and cool videos! 😀
The MOCHUB listing includes every LEGO part you need, the engine will run with or without modified pneumatic parts. it will just have a slower RPM with non modded pneumatic, if you wish to mod them i have made a compete set of instruction videos. You will also need the pneumatic tubing, i buy mine on ebay and make sure you get the 2x4mm size - www.ebay.com/itm/1M-Translucent-Silicone-Rubber-Tube-Beer-Water-Air-Pump-Hose-Pipe-Food-Grade/232281653831?hash=item361510c247:m:m5C3AZ3UxnzS_qzw9UVpLfg Thanks
i do infact believe it isnt run by motors but it just feels sorta weird not seeing a motor there, altho its not actually required, i believe the only actual motor that would be functional or required ish is the starter motor, somewhat attached to the engine just to jump-start it
And a gearshift and a battery and suspension and seats and headlights and doors and a hood and wheels and pedals and a steering wheel and a car frame and an exhaust and a computer and a dashboard and a car "skeleton" and holy crap you made a car (comment what else you want me to add)
Charlie Christensen it would be a tough sell. LEGO stopped making those pneumatic cylinders well over a decade ago so to start making them again would probably be a pain...
nicjasno 's Mustangs has a pneumatic engine, it sounds so realistic especially when it goes over bumps! :D Also this sounds like a dragster! :D Awesome!
It’s a good idea. Rlly you could make these for real cars. Air quality doesn’t matter, cuz unlike combustion engines, these wouldn’t require oxygen. If with an air tank and air compressor that runs off the pneumonia engine
Green Gecko Lego Technic Workshop haha thanks for replying maybe if you come up with a more compact design then you can measure the absolute maximum rpm the motor could take
i would say it would be able to run on it, however it would not have maximum power or rpm due to the limited pressure and air flow. just use a air tank, i made a video on it. it uses a soda bottle.
Hi Luis, all the detailed building instructions and all parts are now available at MOCHUB: www.mochub.com/moc/v8-lego-pneumatic-engine-green-gecko Hope you'll like it :)
Next Challenge! Build a working Automatic Transmission with Torque Converter (using Aerodynamics rather than Fluid Dymanics) to bolt onto the engine! :D We could make a fully functional RC Lego Car functioning on real principles! - Really Really Impressed with this V8 Engine though! This is the sort of things I want to be seeing on Lego Ideas and becoming sets! :D
Nice engine! Although I thought you would use the large cylinders and 32 tooth gears. Would you be able to make an engine like the description I gave in a future time? All in all, I am impressed with this engine.
thanks, i reason i went with small cylinders is because it made the engine way more compact and still has heaps of torque. more than enough, even for a car the size of LPEpower's mustang. i might build a v8 with the large cylinders, but i see no reason too.
this engine was designed around the small cylinders, to make it more compact. you cant use the normal size. but you can buy them on bricklink fairly cheap
very nice! i might build this sometime but first i need more switches and cylinders! :D mine all broke. i think ill also buy a good drill bit to modify them... i get my cylinders for 5 euro's each what about you? the switches 2,50 euro each... that will cost me 50 euros for the pneumatics only :D lol
and whats most interesting is the engine is alot more torque efficient than a internal combustion engine because the piston is powered in both directions. kinda like a steam engine.
I made it without modified switches and cylinders and i get about 1000 rpm out of it! Awesome engine! I run it on more than 6 bar (more than 100 psi) and tubing stays on very nice and tight! I use 1/8 x 3/16 tubing not silicone, with 2x3mm silicone tubing between the tube and inlet. If you have instagram please follow me to see my version of your engine! @lwc_joranprins
Could you put some instructions in a link I really want to build one I’ve been trying for a while and can’t figure it out an also a parts list if you can?
The instructions for this engine will come out soon, there will be a parts list and pro instructions for this engine. i might be going on holiday for a week in a few days, so the instructions might come out near Christmas. Thanks, this engine will be in my latest upload in a hour. stay tuned
Hi Nick, all the detailed building instructions and all parts are now available at MOCHUB: www.mochub.com/moc/v8-lego-pneumatic-engine-green-gecko Hope you'll like it :)
Very nice project. Do you think, that it is possible to power it with a pf Motor directly? I just want to have this sound. And if not, how long does it run with the Air Bottles? But first i have to wait for v2 :P
Thank you, you can't use a pf Motor to run the engine to make the same engine sounds. I Think this engine was using around 4-5 liters a minute, if you build a 5L tank it will run for around 1 minute, I will test this in the MK2 V8 video. The new MK2 also revs higher and smoother than this one, i got it to 2000 RPM and around 1700 at 55psi (this one revved to 1500 at 55psi)
i think you should measure the rpm of the actual crank, or do the math because the tire is rotating slower. i'm guessing it was around a 1/3 gear reduction on the tire, so the engine rev's much higher than 1500
No, i think you are confused. it is correct, the RPM tool measures how long it take to complete and rotation. And when the reflector reflects the laser, it gets a reading. it does not make any difference if the tire has a diameter of 80mm or 20mm, it makes it will always be the same. 😉
This engine will rev twice as high a a big cylinder V8 at the same pressure. LPEpower runs his v8 engine over 100 psi, to reach a similar RPM. The engine has plenty of torque, it powered my HOT ROD well. small cylinder allow for the engine to be more compact.
depends on a lot of things, my i3 is a great engine if you want to use standard size cylinders. it has heaps of torque and great rpm. it is also very compact and can run with or without modified cylinder and switches. small cylinder engines like this one are the best for efficiently, the instructions for this engine will be out soon.
This engine runs on a custom air tank set up or compressor. you need a good amount of air flow to reach 1200-1500 rpm, the lego hand pump is not really a good air source for pneumatic engines. it would only be useful to check the motor timing. that is why i left it out. i will indicate that you need a air source on MOCHUB. Thanks
Damn...
sounds like a V8
yep, even sounds better in my hot rod...
What's up with the crankshaft though the postings dont move like normal v8's that I see. It does sound really good though
It’s not quite a v8 but it’s definitely an older inline I believe
Even if 😂❤️😉
Hi! I didn't have 8 of those small cylinders so i builded a 4 cylinder version. It worked very nicely and i got 1240 rpm without modding anything. Cool engine and cool videos! 😀
Awesome!
interesting approach with the small pneumatic cylinders. will you use this engine in a model?
hopefully in a muscle car : )
you will see today ; ).........
I would love to see an actual lego car with this engine
I have made one, check out my other videos
You should really build a inline six engine based on the Cummins 6BT and see how close you can get to sound like the real thing
sounds like a great idea : )
Any way you could release a video on you building it with instructions i really like the design and would like to build one myself
yes, that is what i will do.
How much HP it has ?
A MK2 version of this V8 is coming this weekend, i will try and calculate the HP then. I already know the cc and RPM of the new one, it revs to 2000!
@@GreenGeckoLegoTechnicWorkshop OMG I will buy it instantly. :D
Am going to buy that set on mochub, but has the set every pneumatic part i need. And i guess the parts arent moded right??

It would be cool if you can add an exhaust
The exhausts are in the switches, i am also building a new V8 LPE at the moment. It will look more realistic.
can it work same when we use pneumatic switcher without modify
yes
How to make pneumatic air connection for getting continously rotation
ok
Also make a transmission for it
That's the plan
A boxer is much more stable :)
someone shoud take it apart and copy parts and make the parts out of metal or aluminium and then try to run the engine then more rpm
sounds like a lot of work, it already runs great. anyway, it wouldn't be "lego" anymore.
That can be an Scania engine #LoL
Put your lego engine in a lego boat .
already done that with another engine
Do you have the Instructions ready?
no, i will be making them soon. i had to use the engine in the hot rod. when i make instructions the model gets dismantled...
Rip;-;
Doesn’t sound that bad at high RPM
Thanks
The sad thing is, people always think your hiding a motor somewhere 😭
i noticed that...
I thought he was starting it with a motor and then taking the motor off
well, he is hiding a 20L air tank
i do infact believe it isnt run by motors but it just feels sorta weird not seeing a motor there, altho its not actually required, i believe the only actual motor that would be functional or required ish is the starter motor, somewhat attached to the engine just to jump-start it
Make a transmission and differential
And a gearshift and a battery and suspension and seats and headlights and doors and a hood and wheels and pedals and a steering wheel and a car frame and an exhaust and a computer and a dashboard and a car "skeleton" and holy crap you made a car (comment what else you want me to add)
Do a flip
Έφη Νικοπούλου thats not gonna cut it tho
2003 Honda Accord You're right...
Make the entire car
they should totally make a kit out of this
well you can buy my model on MOCHUB, link in the description.
Green Gecko Lego Technic Workshop have you approached LEGO about introducing this?
Charlie Christensen it would be a tough sell. LEGO stopped making those pneumatic cylinders well over a decade ago so to start making them again would probably be a pain...
PurpleNinja 82802 um no they didn’t, they are still in many sets, look it up
Anyway it would be a problem to get the air pressure
Lego pumps wont get the 1 to 4 bars required
Really enjoy it. Let's check Avasva plans also
Thanks!!!!!!!!
nicjasno 's Mustangs has a pneumatic engine, it sounds so realistic especially when it goes over bumps! :D

@@JohnDeere2025 pneumatic* not pneumonia
Rev it until it explodes
not sure that would be a good idea
Green Gecko Lego Technic Workshop haha thanks for replying maybe if you come up with a more compact design then you can measure the absolute maximum rpm the motor could take
It won't go fast enough. It will reach a flow limit due to the valves, it will leak, or it will overheat.
Why would you want to kill a good lego pneumatic engine ?!?!
Nice work! Also - how did you get that smooth camera movement near the start of the video? 🤔
thanks, i used a camera dolly
Starting to get the hang of my new camera setup ( Nikon D5600 ) 😉
Green Gecko Lego Technic Creations I am glad to hear that and I know it is a lot to ask but could you notify me when you post the instructions please.
sure can, ive been on holiday for for the past week. that's why late reply
yes
can it power its self some how
I'm gonna put this engine in my real car
Sounds Legit 😅
cant hear over the music. but still great video .
Buy the MKII V8 Engine on my Store, 2200 RPM Version! All Pre-Modified - www.greengeckoworkshop.com/
How long can you power this engine with your 20L air tank?
i get around 4 minutes, i will measure the liters per minute today
Do you think a lego compressor with 8 pumps can run that engine? Something like this ua-cam.com/video/U24nkPSo75U/v-deo.html
i would say it would be able to run on it, however it would not have maximum power or rpm due to the limited pressure and air flow. just use a air tank, i made a video on it. it uses a soda bottle.

Sounds like an engine that could sit in a tank :)
You should build a Scania 142 or 143 MOC to put this engine into! It sounds just like a Scania V8!
Great idea, a second version of the LPE is coming out this week. Maybe that would be a good vehicle to put it in.
Green Gecko Lego Technic Workshop It certainly would, especially since 2019 marks the 50th anniversary of the Scania V8.
LOVE THAT ENGINE ROAR!!! SOUNDS SO REAL!!!
Wow this is such a amazing v8 engine....very realistic great design by the way
thank you
would it work to have an overkill lego car where each wheel is powered by one engine ? :3
You can't ever have enough horsepower! 😂
What do you think about my rc battle bug its a rc walker
seen it

Sounds like 68 chevelle
Couldn't you use the v8 backwards? (Crankshaft generates pressure)
When a Lego engine sounds better than my motorcycle lmfao
Amazing work
Please please answer!!! I want to make simple engines but I don't know what pieces to buy, like do I get the cheapest ones and call it a day?
Wouldn‘t two switches work as well?
More airflow with 4
i recomend a car frame for it 😃
1:33 Вспомните Chevelle SS
Put a starter motor on it and fan with fan belts and a fake radiator. Then it will look real
can u make a v16?
Is there any way to limit gear slippage from the crank to the camshaft? Mine skips a tooth when I put load on it, which messes up the timing again.
There should be no slippage at all, you may be using worn out old parts and they are not hold together...
@@GreenGeckoLegoTechnicWorkshop alright, it doesn't move when I run it on air, but only when I turn the crankshaft by hand.
what could you power with this? make V8 milkshakes?
Sounds amazing
The best looking, and sounding one I’ve seen👌
Is the air tank off screen or is it buried inside the engine?
off screen, it an 20L LPG bottle filled with air : )
Green Gecko Lego Technic Workshop Do you plan on incorporating an air tank on the final build of the hot rod?
i would like to, we will see. but i don't think it will fit.

Not gonna lie that actually sounds similar to a real engine
sound is unreal, i think ill buy this soon...
Great MOC and video! Will this work with standard size pneumatic cylinders (I notice that these are the small ones)? Best wishes, Tim

no, i use a 2mm drill or a 1.5mm for the new type of ports.

Hello, where can I buy one of those motors for my son? Will it be achieved in Venezuela?
Hi, Yes I ship to Venezuela. You can purchase them here www.greengeckoworkshop.com/collections/lpe-engine-kits

How do you get the air in?? I'd like to use such a motor for a Lego tank
Using a Air Tank at 55psi, check out my channel for the video on the air tank
You should Supercharge or turbo it. that would be interesting.
A working Lego Pneumatic Turbo is currently being developed, stay tuned for the MK2 of this V8
How can you handle the rpm
I have been watched this video about 15 times cause the engine is very nice
I want to put this in a lego car
Where you buy those cylinders
Pute that that thing in a rc car instead of a gas tank
you could use an air tank...
Already Have... Check out my Hot Rod
Sounds like a diesel inline four
its sounds like a diesel-V8 like in a pickup-truck!
Hey so, where does the air go out? Like is there an exhaust?
Yes there is a exhaust port on the switch
How do u start it and rev it up?
it runs on compressed air
so this is what years of learning to be an engineer looks like
The only channel where they seem to answer all questions in the comment section. Don't ever stop that. I feel it's important.
Yeah, i also think it is important to answer your questions and comments 👍

Could you run it with CO2 cartridges people use for paintball or softer guns?
CO2 is too cold for the plastics, the cylinders will fracture while using CO2
That’s a pity. But it still sounds pretty cool.
Man.... 😮, You are absolutly crazy genius! It is cool as... I dont know how, but I think it is the best engine of all Lego....
thanks, i is one of my best engines. i have a hot rod video coming out in a few days with it in it, you can check out the chassis video.
Do you think it would be possible to use this engine in a 4 pound tank with transmission, clutch, etc?
Yes that's no problem for it, you might want to build the new MK2 version of this V8 LPE once it comes out this week. It Revs to 2000 RPM!
i think you should measure the rpm of the actual crank, or do the math because the tire is rotating slower. i'm guessing it was around a 1/3 gear reduction on the tire, so the engine rev's much higher than 1500
No, i think you are confused. it is correct, the RPM tool measures how long it take to complete and rotation. And when the reflector reflects the laser, it gets a reading. it does not make any difference if the tire has a diameter of 80mm or 20mm, it makes it will always be the same. 😉
How does this engine compare to a v8 with big cylinders? I see the RPM is about the same, but is the torque compromised?
This engine will rev twice as high a a big cylinder V8 at the same pressure. LPEpower runs his v8 engine over 100 psi, to reach a similar RPM. The engine has plenty of torque, it powered my HOT ROD well. small cylinder allow for the engine to be more compact.
Impressive! :D

You should indicate if the hand pump from lego are in the mochub inventory, because I do not think so.

thanks
I am building a dragster at the moment
I like to build LEGO mechanical clocks
Broo that sounds like a idle muscle car so cool
Hi, nice work! Is it neccessary to have mod switches and cylinders? Or is it also possible by using normal ones?
it is not necessary, however the engine is able to have more performance using the modded switches and cylinders.
No need gasoline lol
Is it self powered and self sustaining?
No, it needs compressed air to make it run
Would the pipes or any connections blow at 100+ psi?
Also if you glued the pipes, or melted them together would you be able to put more psi in if, or would the Lego just fatigue?
you need to glue the hoses on for over 60 psi
i have seen LPE's run over 150 psi, they are fine until they get too hot
Great build
