War Thunder is many things at once, but free aint one of them
@maximilianbroucek4748 free to play, pay to win. Then again, as a war thunder adict myself, I can't say much
Route the coolant hoses to the sea water, will hold up much better
try a dual v8 engine powered paddle board or boat maybe
i'm moving back to seattle soon, do you as a mad scientist need a henchman assistant? i would be honored to be your henchman. ;D
It's so cool to see one of these engines ACTUALLY being used. Every video on youtube of these small engines is just reving it on a desk.
It probably needs WAY bigger jets for the carbs since it probably is just fueled for free reving
Watch JonnyQ90 he makes car out of them
@@stevegredell1123ye it needs a lot of improvements to it
No it isn't❤
Dennis Dempsey is another channel that does more then run them on the bench like JohhnyQ90.
Today you learned what many a car guy has learned. We all hope the cool V8 will get the ladies, but it ends up just being a bunch of dudes. Lol. Awesome build bro. Keep up the awesome work.
It's kinda like owning a motorcycle. It's a dick magnet. Been riding 10 years, not one woman has ever checked out my bike.
@@dhelix85 depends on whether you count looks of annoyance and disdain as "checking out" lol.
@@tissuepaper9962I think that mostly is about the quality of most females out there. Most are self absorbed, and interested only in themselves.
Well, it was a boat so his odds were better than a car or motorcycle. But he would need a much bigger boat. Size matters...
Girls will only look if it's a Harley and an open-faced helmet. That's how I met my wife. She was a country girl who trained horses. I was a country boy with a Harley Night Train. If they can't see your face they won't even bother.
"I have not seen a single lady but there's five dudes lined up on that dock" Lolz
I love how the mini V8 still has that V8 sound. It would be cool if as your next solar boat, you did a combination solar and sailboat.
Right? It sounds exactly how I would expect a cartoon-shrunk V8 to sound
needs 8 to 1 exhaust
@@mannine99 Nah, dual equal length headers IMO.
When you spend to much time alone on a solar boat....
🤣
130 miles alone on a solar boat
Yep
When you spend the perfect amount of time*
He’s gotta make up for saved emissions somehow!
You should make a Thailand Longtail boat! That motor is perfect for a longtail. You would have full power no complex gears and be able to easily control and steer the boat with a standard motorcycle throttle.
Awesome idea
yip thai longtail is worth a try ,
You should I dare you
Double dog dare
Also, the boat profile would create less drag = higher speed
13:45 That felt like the gym meme😂. You go there to get jacked up and get the ladies, but the only thing you get is gym bros admiring your effort.
It's great that you got the toroidal propeller to work, since it's so much quieter than traditional propellers. Definitely makes a difference in this build... Totally...
Please do more videos with this engine. As many have said, nobody uses these engines to do anything cool. I'd love to see it tuned and running well. Thunderhead289 has great carb tuning videos.
I'd say the stock carbs need to be tossed and replaced with a good slide carb.
Needs a radiator too! (Or other thermal control)
@@Blake_V Another youtuber (JohnnyQ90) found that modifying the timing system lets them rev freely. Most of them ship pig rich to make them last longer as well.
8:59 FYI, you can buy electromagnetic clutches that would fit the size of that motor. They're belt pulley motor clutches meant to disconnect a belt from its intended purpose. If you machine away the pulley part, you can then mount it with a bracket like you'd mount a car clutch and drive it with 12v.
You would be better off using something less complex that doesn’t require extra energy “other than the engine” like a centrifugal go cart clutch. No engagement lever or mechanisms. It’s in freewheel mode at low engine RPM and slowly gets to near full lockup at design RPM.
It’s neat to design/ build your own parts but it’s a lot easier if you’re not “reinventing the wheel” on every one of those parts. Some designs like the go cart clutch are so simple and dependable that there’s no need to “rework” them.
my first thought was thinking trimmer/chainsaw, you dont need power and you dont need to manually engage. im not sure they would hold with that engine, so mower/go cart
Just use an a/c clutch from a car.
smaller engine better off with weedeater clutch because fit perfect size and go kart just too big and too heavy because weedeater have alminumin clutch not steel like go karts
Yeah i'm not going to lie, that is definitely an incredible intro Daniel haha. This was a really well shot video - all of it was smooth, including War Thunder. The sheer amount of effort going into this project is insane.
Thanks Jay!!!
Very cool project you’ve created. You should try running the coolant intake line(s) into the lake and add an electric pump to circulate the water through the engine and back out into the lake. That should keep it plenty cool at a relatively consistent temperature. Excellent job on the 3D parts design and printing. 👍
A liquid-filled torque converter would be a really cool project.
There's a guy who build one
@@braziliansheetbox2497ich kenne den auch aber ich denke ab 7000rpm wird der explodieren au.erdem würd der auch sehr heiß werden
Is there a link available to this video
yaa
I think you need to make like a 1/5 scale cigarette boat with these engines. It would be one of the funniest things on the water
That would be so awesome
"YOURE OUT OF TOUCH
IM OUT OF TIME"
yes but with twins
@@Eargesplitten-Loudenboomer based wildcat round
Yeah, that’d be really cool.
Might actually pick up some speed as well, if he tuned the engine a bit more
I'm impressed how well those 3d printed parts held up
Great video! I think an easy solution for the noise produced by then engine is to route the exhaust underwater. That would eliminate most of the exhaust noise and you could hear more of the engines mechanical noises and maybe preserve your hearing!
Nice idea!
that anti freeze bit at 5:05 actually kinda worried me lol
Id be surprised if it was real anti-freeze or coolant if he was just running it for that short and in warm weather where freezing water isnt an issue.
@@isRANDYasian I kinda thought he might have substituted mountain dew, it would taste better than anti-freeze.
@@ianhoyt2638 marginally
It's gotta be mountain dew
Propylene glycol (antifreeze) is also a food additive used in ice cream and sodas, even in e-cigarettes. I'm sure it's perfectly safe:)
That little V8 is $2,900 that’s crazy. I bet they don’t sell very many of them. It’s a cool engine though. Nice job on the video.👍
Niche market but they sell well enough to keep the company alive
That's the price of a crate ls1.....
amazing
I'm actually surprised this engine can run under load for this long without a major failure. Also I think more reduction with big prop is going to be the way to go.
Kudos for being the first person on the Internet to actually get real work out of one of those motors! I'm somewhat surprised it ran so long without breaking something on the motor itself.
These engines often run rich from factory, once run in you might be able to lean it out a bit to make it run a little better. Ignition timing might also be insteresting to look into to make it run better
A 2 stage clutch might also be interesting, using both your 1st and 2nd design.
Running on 100 octane Ave gas or an ethonal mix would allow to give it more timing and keep things cooler. May need these steps to preserve the motor for longer life.
Right mouse28. But boats dont need clutch, just bigger starters.
It also helps to lap the valves on these engines
@@pepethefrog7193 That does relieve the need for one, LOL
@@aidanstrunk4141 Do they not seal well enough?
The water pumps on those tiny engines are typically well undersized for the cooling needs of the engine. I think a reasonably powerful little electric pump would be the way to go to make sure the engine isn't getting too hot. Also if you swapped the starter motor for a DC motor you could use it as a little generator and maybe keep the batteries charged.
Presumably you could also cool the engine using the lake water instead of the coolant?
@@willtwilson it looked to me like he was already doing that. Since the hot output was just going overboard.
@willtwilson that's what he's doing
@@quinnobi42 I dont think that would be good for the engine. The salt in the water could damage the engine. Running the pipe under the paddleboard and then back into the engine would probably work better long term. (Short term you wont notice any issues with the salt water)
@@freddo5677 You raise a good point. I hadn't considered the salt water. In which case a closed loop cooling system with water to water heat exchanger would probably work best.
This is such a cool project. I'd love to see more done with miniature engines!
I love the bumpety bump clutch! I love it specifically because the mercruser alpha drive has essentially the exact same thing in the lower unit.
The dog gears in a merc alpha drive are a sawtooth shape so they slam together but disengage smoothly.
Best intro ever.
Shame Gaijin Enteratinment KFT ruined it with a sponsorship. Seriously, never use Gaijin as a sponsor ever again... and maybe also do the same with WarGaming.
Tucker your here too you are one of my favorite TH-cam channels
It’s so cool that it’s possible to make such things in a home shop. In the old days it probably took a million dollar lab to do it.
We are in the future we dreamed of! Makers going crazy, left and right 😂 Cyberpunk, here we come!
Well, building that engine itself at home would be a monumental task
Old chaps are doing it just with a file.
@@Henrix1998 But still possible. There is a lot of engineering that would go into building a V-8 but the tools and machines to do it totally doable in a home shop.
A popular youtube channel would have manufacturers sending machine for for free
It’s kind of the opposite. In the old days guys were doing cool shit with really crude machinery but incredibly talented hands. They didn’t have nearly as much competition though so they could take years prototyping things and then just make small batches
Taking influence from real ships, running the coolant pickup line below the paddle board's water line would help keep it cool, although the water pumps in these motors do not have very high flow and are prone to failure. Also, running the exhaust down into the water would solve the noise issue; add a water box or flapper to keep water from running back up and into the motor though.
Freaking so cool. I love seeing 3d printing projects like yours. Keep it up man. Enjoying your videos.
Put an exhaust pipe that goes in the water, not only will your engine be quieter (IDK if you have ever heard the sound difference of a boat engine running in/out of the water) but you might even be able to get free power from your exhaust gases.
that would probably inhibit exhaust flow, since it has to push thru water to escape. much quieter tho!
@@pauls5745
yeah, that's true
however, this was never an issue for boat engines, which dump their exhaust in the water
I don't think it's gonna be an issue for this one either.
The fish have to put up with enough racket and animal abuse already
@@polok890
that's not the most noisy: the worst are cavitation bubbles, and based on the lack of propeller destruction, these propellers don't do any.
@@polok890oh hush
Clutch springs have to be massively powerful. Even with modern clutch materials the coefficient of friction isn't nearly as high as you would imagine.
I guess they use hydraulics in clutches for a reason
@celeron55 spring clutches are fairly common still but the lever/pedal ratio is pretty high with a very small throw on the actual pressure plate. But yea, hydraulic clutches were definitly invented for a very good reason.
Springs are what some scientists may call compliant mechanisms by themselves, so they're pretty much optimal for almost any given task, you can always scale the spring up if necessary, and it will always work, hydraulics, being superior even to that despite having more than one part involved is truly impressive.
@@TBradyMost clutch pedal to movement of the plate ratios are like 50:1 or something like that right?(source-it was revealed to me in a dream) And even then it takes quite some force to release them. Stiff springs for sure.
He should just mount it direct. It's not going to move very much at idle anyway.
This is awesome! Full size boats use a micro switch that cuts the ignition for a fraction of a second to go into gear more easily. And the idle has to be pretty low, maybe you could ad a spring to push it into gear once you move the lever?
This is awesome! Hope to see another iteration if you figure out the running issues
Wow, that's some top-notch green-screening and explosion-overlaying.
Also, the "bumpity-bump" clutch worked really well for the first try. Didn't even shatter/explode!
It is incredible you can generate so many videos and make products at such a rate, I have been following for some years and have never been disappointed in the value of your productions and I watch a LOT of content.
Being rich is literally easymode.
I've been watching a channel who buys literally every model of these miniature engines and then adds some things to make them run well.
(For the metal in the oil, he tends to let them run in for up to a couple days before ever seriously revving them)
He uses some of them in RC cards.
What I'd love to see is one of the real car engineering channels, who manufacture parts, port valves and tune the cylinders to perfection, really go ham in modding engines, to pick up some of these mini engines (they come in everything from straight sixes to V-12) and modify and tune it to perfection.
If I'm not mistaken, the mini V8 is capable of about 3HP out of the box with standard parts and that's with somewhat questionable finish on the parts.
I'd love to see someone go ham on engineering a good engine out of it, put all the different engine tuning stages on it and see how much power it can make then.
A total tonne of fun! Great work! Mostly these mini V8s never really sound like real V8s but this one really does! Awesome!
The CNCd plank was pretty cool
Turning it into a generator to use as a range extender would be interesting
I feel like this is it's destiny, although I hope we get to see a Thai longtail paddleboard along the way.
Porsche moment
Only, he’d be better off adding batteries and/or solar.
@NZobservatory yes - thats what I mean. The generator will top up the batteries
@@johnsfarm7760 For all the weight and complexity involved (and the small dividends vs inefficiencies) an ICE generator is more trouble than it’s worth. Increasing solar and/or battery capacity makes way more sense.
What an interesting video, I loved it and I am an artistic person, a musician in fact and I love how you explained how everything works! Your commentary was excellent and so was the filming!
Dude yes. So glad to see these actually being used. Electrics are kewl but this is just way more impressive 🤘
Bogging at WOT makes me think your mixture is leaning out as you give the motor more air. I bet you can tune that out with new jets.
If those are weedwhaker / chainsaw carbs they have mixture adjustment screws. Look for a brass plug with a notch in it. Dremel the notch into a slit and rotate it with a screwdriver.
The universal joint is not ideal because it is not a constant velocity joint. It "pulses" as it turns if it is not straight. A way around this would be to use two joints out of phase, but they need to be arranged so that both bend at the same angle. For a clutch, I wonder, can the electric clutch from a car's AC pump be operated progressively? Otherwise a simple system would be to use a belt drive as an adapter and just control the belt tension to work as a clutch.
Clutches are for woman. We no need that.
Ah I see, going the SuperfastMatt way!
Now there's a sublety with UJs based on experience!
Out of phase will double the pulses. You want them in phase, so they cancel each other out.
@@robertheinkel6225Pretty sure that's incorrect. The effect is sinusoidal, and pulses at twice the RPM - in-phase is constructive interference, so amplitude will double.
Anti-phase is destructive interference so nullifies the effect.
As a full cycle happens every 180° then antiphase is 90°.
Words cannot describe the emotional distress I am feeling hearing you engage that clutch
this is the best video I've seen about a miniature engine, also very interesting with what you did with the clutch, I have a 1926 Bentley and the gears use the triangular couplings so every time you put the clutch in on your engine it reminded me of my car with the same sound haha. brilliant video earned a loyal subscriber !!!
Try a variable-pitch prop. Then you can engage the clutch and rev to peak THEN start coarsening the pitch. You might be able to produce more power since you are already at RPM before giving it a load. I had a moped once that could get up to 28mph on level ground. However if you went down a hill it would speed up, then hold 34 once it leveled out.
Right it would be like a grass trimmer, You need high or max RPM before load is applied.
That engine probably needs to be tuned a little bit. It might be running rich with the smoke coming out of the exhaust.
Really cool concept with the V8! As for the clutch, I'd love to see it implemented the way Thai racing boat enthusiasts do it!
You pack so much work into such a short video, its amazing! Awesome job!
Instead of a clutch, you could try just lifting the whole prop out of the water on startup. That's what they do in East Asia. Or just buy a gokart clutch.
you should totally get one of those kayaks we saw in the start of the video, strap this or another engine on there, with clutch and gas pedals, steering wheel and and an accurate speedometer.
I'm thinking leave the clutch and throttle as hand levers, use the pedals for steering.
yeah that could also be a great idea@@tissuepaper9962
Great job to see one of these used mine I have for 3 weeks will not start everything looks correct spark sensor fuel it will not start at all. Keep up the good work.
Surprisingly good! Sounded the part and looked cool doing it
Every time you change the oil it's a different color lmfao
Would be cool to put the exhaust pipes slightly under water. This would maybe make good bubbling sound.🥰
probably would have quieted it down as well, but then it wouldn't sound like an actual v8 car engine
On Aussie inboard ski boats with real v8’s they put the pipes under the water and they’re nice and quiet at idle
Love how you guys combine engineering with having fun. Best way to learn.
it was so great to se somebody use this in a practical application
It's about time somebody actually put one of those Motors in something to make it work😜🤪😉
"Electric boat man finally snaps: makes gas guzzling surfboard"
Yo Daniel, i absolutely love this. I've replayed this video a few times already. I've been following you for a long time ever since you made that busted rc solar car for a school project. And out of all the projects you've built, this is by far my favorite one. I love rc the solar stuff and everything in-between, but this little v8 is so sick! I really wish people would use these things. It seems plenty capable i would recommend looking at re jetting the carbs or seeing if the AFR values are off. I know you can open this thing way more than you've shown! Also, a video of more raw content of the boat i could listen to it all day long.
I love your videos so much and I'm looking forward to propeller test!
Keep up the good work 💪
I wonder if you could increase efficiency if you changed the U-Joints in single arrangements to duos. The engine wobble may possibly be due to the single u-joint arrangements causing nonconstant velocity output as well. If you added a second UJoint it wpuld counter the other and gives you a nice constant velocity output. and erase the slight horizontal movement that comes with a single joint system.
My thinking also!
or replace it with a CV joint, you can find them as ratchet swivels these days.
@@brianwelch1579 a true CV or a cardan?
Never seen a true CV on anything like that before 🤔
Would love to see more with these small engines. Water, land, air whatever but this is a very cool concept that you dont see often. Thanks for making this! Very well put together video.
Ive been into Drag racing for years and one of my drag cars has a manual dogbox gearbox simlar to the one shown here in your video. A common saying you hear with a dogbox is to "shift it like you hate it" and I cant tell you how true that is. If you try to shift smoothly or how you normally would shift all you do is grind gears no matter how much force you put behind it. The key is quick stern shifts like your mad at it , and then magically its smooth as butter.
Crazy amount of work in just one video, awesome!
This is an incredibly well done video. Thanks for keeping everything actually valuable and not just fluff. Great video.
I have had the luck to work on about 8 conley v8's. And as you said, most of these engine are just ran on a stand. I'm very impressed to see under heavy load it held up.
Love EVERY part of this vid!!
Wish i was there to help in design!!
I always wanted to put 1 of these engines to "USE"....
try using a thinner or less dense foam for the intake filter, it might be starving it for air. also get an afr wide band to tune it. amazing to see one of these ACTUALLY put to use. keep up the amazing work!.
It's like 2 things I really enjoy very much have meshed together... Rctestflight and IC horsepower. The fact one of these mini motors is actually being used for something is the absolute cherry on top!
I wonder how difficult it would be to make these engines electronically fuel-injected? That would be sweet! there are plenty of inexpensive programable ECUs out there like Alpha X and Speeduino.
Rojo makes a complete kit for 50cc mopeds i have this on a 72cc monkeybike.
This tiny engine hooked to a dynamo could be a nice range extender for your electric boat - when the solar panels dont produce enough, or if you need them away
I love this. I’ve always wanted to do something with one of these motors and this is sick!
This might help in a future build, but if you want a clutch and don't care about slip ("on" and "off") I would suggest looking at how differential lockers are designed. Any true locker (not a limited slip, obviously) should work, but auto lockers in particular do exactly what you were going for, and are of a very similar design.
Nice job btw 👍
Would be cool if you designed a cvt for it. Seems like it’d help with getting into the higher rpms
He needs to make the timing adjustable like Johnny Q90. makes this thing a beast
Pretty cool that the Clutch works :)
Maybe a little difficult to implement, but a "continuously variable transmission" is an option to regulate the speed better. It is basicly a stepless transmission but maybe easyer zu build than a "real" clutch.
sorry for my bad english :D
I live right by lake union! its great too see someone actually use these mini engines
A few Ideas I thought worth sharing.
On the outboard unit, have the stearing pivot axis oveverlap with the axis of the vertical drive shaft this way no mater which way you turn, the vertical drive shaft will remain in the same position relative to the paddle board, base, etc. This will eliminate the need for a U-joint of any kind.
Instead of running coolant, have the engine take in cool water from the lake and dump it back out; no recirculation. This is the standerd in the boat industry. You may also want to use a small sea strainer if you go this approach.
For the noise, you can always extend the exhaust to go into the water.
I really hope you figure out the carburetor issue.
Anyway, that things super cool!
I hope to see it refined and back out in the water
ope lol you beat me to the punch just left a comment about the coolant and the exhast.
Love you content bro, keep it up!
That was cool!
Edit: Subscribed, and looking forward to the next episode. And also going through your entire back catalog! 😜
This video was just fun to watch. I loved it. Thanks for sharing this vid, I’ve now subscribed.
I think I'd like to see a v8 Unicycle (peak impracticality)😅 Although a "most practical" mini v8 powered something, like a paper shredder would be cool 🤔
nice one daniel this is awesome
i think the carburettors should have a 'high speed' adjustment screw for higher throttle positions
try turning it in or out 1/16th of a turn at a time and see if it makes a difference. the fact that it bogs down when you open the throttle more whilst under load suggests to me that it could be going lean.
I thought about this a lot I'm thinking the carb adjustment is fine and the problem might be no exhaust. The same thing happens with 1600 vws and 2 strokes with no exhaust in my past experience
Not enough gas going in at high loads with the throttle wide open. Be careful about running to lean, it will overheat and also burn the valves. Try bigger jets if possible. I imagine it was originally set up to run on a bench with no load. Have fun...and try a weed whacker with a propeller, if no one has done it before.
These little engines are known to have a host of problems from the factory.
Some of the most common ones I've seen are the double spark gap in the distributor, poor timing, restrictive exhaust manifold, undersized water pump.
Once people fix those, these engines have a noticeable difference but sometimes rip themselves apart.
Some of them even have superchargers available which can help increase their power as well by a little.
That is AWSOME content !
So entertaining. Sounded so great !!!!
You need to move your weight a bit further back to plane. I don't think you have enough power though. Less wetted area and displacement, less drag. As you are nowhere near full motor output, go lower pitch and diameter on the prop. Lower pitch will give you more push but less diameter will unload the engine more and possibly permit sufficient combination of torque+RPM to get your SUP board to plane. That's your next goal. From there, you can optimise pitch and blades, diameter to get best planing speed. Beware water ingress into cylinders. Trying to compress water doesn't end well. For that reason, don't put hydrofoils on at this stage. Lots of refinements needed yet.
Yes, scientific approach totally missing here, just accounting on the mythical name "V8" to solve everything. You should put your motor on a power bench to find out at which RPM you get the most power,then determine the speed that you can expect with this power, and enter those number into a propeller calculator that will give you the pitch and diameter you need.
a chain drive for transferring power to the prop would be a lot simpler and less power lossy solution
It's great to see someone actually use one of those tiny V8 engines to power something, thanks!
if you are trying to get it to not bog down in higher rpm you will need to advance your ignition timing in order for the firing to keep up with engine speed and be efficient. This is awesome seeing a model engine being used for something other than a desk ornament!
You are right. I also think it's running lean. If it wasn't it would smoke when bogged down.
wow, you are really getting better and better at engineering bro keep up the great works
To combat the coolant getting hot, you should design something that lets you submerge it in a container as it circulates so that the lake can cool the engine
A flat copper coil mounted under the board should do.
Perhaps a sealed propulsion jet unit (like a jet ski) would work better with that configuration.
Also, mounting the coolant tank or heat exchanger under the board would help keep it cool
this is exactly the content I signed up for :) That little v8 sounds amazing too!
Toothbrush mic is underrated
Next time you are looking at making a clutch like this look into automatic transmission clutch plates. they are designed to hold on steal plates. You just need the correct pressure which is easily produced with a hydraulic pump. Or use a clutch drum and planetary from a auto trans. Just tap threads directly in the drum for a fitting.
I love the energy in this video so much fun keep up the great work man
It absolutely sounds amazing
This is so cool. You should try mounting it on the outboard like the 7 Marine outboards. Also the smaller prop should have a higher pitch to take advantage of of the rpm.
Btw if you are interested in other petrochemical vs electric unpractical comparisons you could try making a fixed wing .049 cox powered drone… and compare it to a racing quad motor powered one of the same design. Cox is remaking the famous tiny engine and has a throttle-able RC version.
You have the mind of an elite engineer and the motivation of 1000 men, props to you good sir 🎉
The elite engineer needs to learn about timing advance. You know, like a Ford Model A.
This thing sounds AMAZING. Great to see these toy V8s actually get used for something.
