Very nice! I really wish you made a V12 with the smaller cylinders, ive been knocking around the idea of building a model tank with one of these engines at the heart. Even had what I thought was a pretty good idea to run the thing off of a big paintball compressed CO2 tank at like 4000 PSI, and regulate it down to 100 for use in the engine
I will be making a V12 Engine after this one. CO2 is too cold of a gas for the plastic under high pressure, I would have to upgrade it to metal cylinders some how. Good idea through.
@@GreenGeckoLegoTechnicWorkshopI know I may be a bit late, but I do think he meant a compressed co2 *tank* , and not actual compressed co2. Could be wrong though
Wasn’t expecting to hear turbo’s sound on a lego engine can’t describe how much it sounds like a real turbos especially that SUTUTUTUTU and how impressive that thing is you did excellent job
I'm half way through the building progress. Fun to build. The instruction is very good and detailed. 100% recommendation. Maybe I have to contact you again, cause I don't know if I should add the turbos or build it without the turbos. If not I maybe have questions because of the installation of the tubes.
Awesome! The Two Turbos add turbo sounds when the engine is running, you can customize the engine as much as you want. I am Glad you like the Engine, I put a lot of time into making the instructions and designing the Engine. If you need any help, you can contact me on my store - www.greengeckoworkshop.com/
@@GreenGeckoLegoTechnicWorkshop Thank you very much. You can feel and see the passion and time you spend with the moc and the making of the instruction. I mean making over 800 high quality pictures take some time.
I love how you can hear the sound of the plastic shacking Legos within the actual grumbly V8 noise. It really does sound like a V8, probably because it is a V8 haha.

Just an idea Make a large plane that’s proportional to the propeller you were using. Have the engine connected both to the prop and wheels so it can taxi.
It's one-stroke so it has four times more power strokes per revolution, but it also spins four times slower than real engine. Sounds like real V8 to me, if I don't take into account it's an air engine, and there are no explosions in the cylinders.
really nice well made vieo with good explainations of the engine , and also not to mention the amazing engine build as well. everything has clearly been optimised to achieve maximun power , keep up the good work.
Good work, although I wonder, does the turbo mechanism just freely spin, or is it connected to the engine to give it more power? Great work nonetheless!
@@GreenGeckoLegoTechnicWorkshop Maybe if the exhaust spinned a more powerful turbine or something that could actually be connected to the engine, it could get more rpms, just a thought.
The engine is just awesome, is that a crossplane crankshaft model you used ? I also have some ideas for that engine if you're interested: Did you try putting a flywheel heavy enough for the engine to store momentum as it runs ? I see you also puttted a gearbox which is great. Have you ever considered building a car around that engine and gearbox ? Addind a differential and then make a whole car of it that you'll put on some kind of dyno. (since it's working on compressed air you're using with a compressor, I assume it can't go that far on the ground ^^')
Thank you, yes it is a Crossplane. You can add a flywheel to the engine and it will run smoother, the propeller blades in the video act as a Flywheel. The engine still runs very smooth without one. Yes I have made a Car with the older mk2 v8, search for LPE powered Hot rod on my Channel. You can add air tanks to a car and the engine will be powered by the air tanks and not need a air compressor.
Thank you, you can buy the engine kit here. It Includes all the Parts needed. greengeckoworkshop.com/products/complete-kit-mk3-v8-lego-pneumatic-engine-twin-turbo-switchless
Wonderful!! I can't wait for that possible future V12 you told me about! Do you think I could create stronger air tanks to contain more air at a higher pressure and then release it into the system through a valve? Would the system hold in your opinion?
Yes, I will make a V12 with 2x11 cylinders. Similar to the mk3 v8. I will also be making a air tank setup for the next project, using paintball air tanks.
Wait, wouldn’t the engine work the same if you just made it so the air from one piston goes to the other piston on the opposite side? You could then disguise those tubes as an intake manifold.
how strong is the wear on the pneumatic parts itself? this MOC looks really nice and the sound as amazing! keep up the work man! i love how people come up with things like the switchless valves u made there.
Thanks, the Pneumatic Parts are lubricated with silicone when they are modified. So there is no major wear on the parts when running the Engine, Lego Parts are high quality and last a very long time.
A thought occurred to me. If you paired this engine with that gearbox (or the 5-speed as shown on the site), and some of the biggest wheels LEGO has made, could it be possible for it to break ~25-30 mph?
@@GreenGeckoLegoTechnicWorkshop I was actually thinking of a land speed record-style build that used two of these engines, each hooked up to one of the two axles. It’d be a single-drive with a 0.5:1 or 0.33:1 gear ratio (spinning the axles up to 3,000-4,500 RPM), the long ratio made up for having a combined total of 160 watts and 1.02 Newton-meters torque. To make up for how far flung it’d be from the original operating position, it’d use small CO2 canisters for fuel, attached to regulators that prevent the canisters from blowing the engines apart entirely. If not a land speed record build, then maybe some kind of top fuel dragster build…?
See now all we need is a way to hook this up to 3D Printer Academy's homemade gear dynamo. If this engine can produce 80 watts of rotational energy, and 3D Printer Academy's gear dynamo can turn rotational energy into electricity, that means I can use your engine and his dynamo to effectively charge my phone using compressed air
Thats really cool! Can you please make a video explaining the turbocharger you used? Im a bit confused on how exactly it works and I havent seen many other lego turbochargers online.
I am currently building a Ripsaw tank which is powered by this engine, I have built a new stronger transmission for it. The one in the video is for demonstration.
Great engine! couldn't you use the medium pistons instead of the big ones because they are just a bit shorter but have the same diameter and would work on that crankshaft.
Thank you. Yes the Medium ones would work on the same crankshaft. However the Extra Large Cylinders work better for this Engine Design, since the Switchless Mechanism needs the extra space above the Cylinders. The Extra Large Cylinders are also very smooth and provide excellent power.
