As a automotive technician in the game for over 20 years.... I have to give this guy my respect. He's doing shit that makes no sense, but that I've always wanted to to. Not to prove a point, not to further my education.... But just because he wants to. Damn.... If only my boss would let me do pointless projects like this.

Crazy Russian mechanic: "We're gonna put five flywheels on this Lada" Crank main bearings: "Say what?"

When a Russian says “it looks dodgy” you want to watch out!!

Thank you for actually doing the stuff the rest of us just sit around and daydream about.

Try the car when the snow goes away, and you have a big dry surface to try it on. You will get another big surprise! Around 1973 a top NASCAR team tried this concept for their car at Daytona. Their reason was that at Daytona they ran full throttle all the way around the track, and the corners would pull the engine down in revs. Their theory was that the energy in a heavy flywheel would let the engine maintain RPM in the corners. They built a 250 pound (100+kg) flywheel and gave it a try. They were surprised to learn that the heavy flywheel was a big gyro and the car would not turn. When the car came to a corner, it wanted to go straight, through the wall.

In Russia the wheels fly you. That little engine has the rotational mass of a Mack truck diesel. Lol

Around 6:35 He says, " It's still vibrating." Of course it is. It's a Lada. If you look in the owner's manual, under "troubleshooting", under the issue of "no vibrations", the response is, "engine is most likely not running"

I can imagine the stored energy from the extra flywheels would be great for hypermiling and coasting. Well done and another great video!

My guess is going to be "The smoothest idle you ever heard."

Bottom of car looks like it might crumble to rust dust at any second: "We are looking very good."

I like how he said “we’re not running a welded diff in this car,” like that’s such a normal thing.

Cool video. It’s extra neat that they got Kermit the frog to do the voice over.

4 flywheels + automatic clutch = the perfect beginner's car.

I bet it could do some wicked clutch pop wheelspin launches. You could have a cheat dragster, just revving a 50 horsepower engine into a giant flywheel for a minute straight, then release and do a tyre smoking 10 second 1/4 mile.

Super. I tried this on a VW Beetle. I only added a little over four pounds at the rim of the flywheel, and not only did the engine rev up and down much differently, if you floored it, waited for it to rev up, and then dropped the clutch, it would really burn rubber. 💙 T.E.N. Edit: After reading a bunch of comments, a heavier flywheel means lower miles per gallon and less power available at the drive wheels, however, initial torque off the line and speed shifting are fun. 💙

It's like one of those kids car toys. The ones where you have to wind it up by repeatedly running it across the floor, then it takes off

That stack of flywheels looks like an iron birthday cake.

4 flywheels adds "a lada" weight, comrade!

Jesus, that is a horror story waiting to happen. The energy in that flywheel stack could twist that Lada like a pretzel.

God I love how these guys improvise.

,,Seems to be some kind of weirdness with the timing chain. My guess is that the tensioner has fallen apart'' *REVS THE ABSOLUTE SHIT OUT OF THAT ENGINE*

I would turn down the idleadjustscrew on the carburetor and see how low the idle can go. With all that mass keeping the engine turning.

Smoothest, engagement, ever. Congrats you made an engine that uses it's power to drive a flywheel instead of a car.

The voiceover is golden LOL I like how he’s translating and in the background my guy is like OOoOoOO

When your flywheels have more metal than the body and frame, lol.

If you used this many flywheels and the "automatic clutch" from before the car would be un-stallable

Obviously the curse of the FIAT 131 rust issues haven’t gone away . 😵‍💫

3rd gear on what appears to be off-roading snow, with no engine breaking and no abs, this guy is a maniac hahahahah

3+ tranmissions would be fun! How slow can you go?!?

Legends say that no learner driver can stall the engine, even on a slight incline.

A heavier flywheel would in theory would have more momentum, I want to see a test of going uphill at 45 mph with and without this modification. I'm wagering the extra flywheels will help it keep steady up the hill than the standard configuration.

You can see that this man is having so much fun. Messing about in the snow in a car that keeps it rev's going looks like great fun.

Keep this car for a later episode. When the snow is gone, do a show on dry pavement.

Its actually crazy that the fly wheels fit together so perfect

Nothing like having a few spare flywheels in your car....you just never know when one may wear out! 😁

To anyone who really thinks that this could work, I want you to understand the function of the flywheel first. This will tell you why this setup would be a terrible idea for everyday driving, but a good learning experience anyway. The flywheel has teeth along the outside to allow the starter motor to spin the engine. No problems so far... The flywheel mates with the clutch to spin the wheels. Since the clutch mounts the the outside face of the flywheel, we still don't have any problems... The flywheel is rather large and heavy. This is to keep the engine running so that the rotating mass aids the engine between power strokes. A lightweight flywheel is better for performance applications like racing, but impractical for daily driving as it would cause the engine to struggle when taking off from a stop. If a flywheel is too heavy, the engine will struggle in a similar fashion. The engine will have to work a lot harder to spin all this extra weight and will also cause rev hang when shifting into the next gear or a higher gear. Thus making increasing rpm and decreasing rpm a much longer and harder task. Here is the problem. There is too much weight that the engine has to deal with, causing it to struggle. You can move the transmission back on a RWD vehicle like this as far as you want as long as it's mounted securely, but if the flywheel is too heavy, there will be lots of issues with the operation of the vehicle.

I like that they do everything in just one episode and not keep waiting like other content creators

perfect for towing heavy trailers! no more crazy reving or stalling at uphill stop junctions!

Would love to see you guys keep this around, and do a fuel mileage comparison on a road with flats and hills with both the stock flywheel or an even lighter one then this setup. Will the added inertia help with mileage over the coarse of daily driving, with a measured fuel source. Great vid. keep them coming.

There is a vehicle driving and building simulator, Beamng Drive, and the physics are absolutely incredible. One user, put an 1100 pound flywheel on his small car....I laughed so hard...it was hilarious!😂😂😂

Tune it rich and watch the backfires.

Sounds like the flywheels are "pushing" the engine when coming back to idle.

Calvin: "That was cool . . . now let's add another SEVENTY flywheels! I wonder what will happen!" Hobbes: "Yeah!"

Great video. I like how you go from one extreme to the other and compare the difference. You are a true craftsman.

i imagine you rev it up and drop the clutch, so much mass burnout in 2d gear xD

Try this on a Niva and take it off-roading. Watch it climb vertical surfaces.

The best description for that is momentum. Something heavy maintains momentum longer than something light of the same profile.

In the old days of drag racing, when only manual transmissions were available, we'd look for the heaviest flywheel we could find for our small block Chevy's, to help with low end torque. The flywheels from the 348-409 Chevy's, (scalloped valve cover motors from mid-60's), were the best 11" flywheel: 50# (~22KG) After they became too hard to find, I ran a 12" Flywheel from a truck, with an 11" pressure plate, and 10.5" disk to make shifting easier. Worked well. Five flywheels = 50% of engine weight

I think the added mass would make an awesome interstate cruiser and also could be used as a mechanical regenerative braking. As you stop you add your forward momentum to a separate flywheel that spins while the car has stopped. When you want to move, engage the clutch to the flywheel first then to the engine to accelerate once the energy in the flywheel has been used.

300 hp nitrous kit on a bone stock LADA !!!

Jesus Christ himself could not have convinced me to get into that cab with those flywheels. The mind boggles.

Always wanted to know what it would sound like if Kermit the frog dictated a TV show

Poor-boy differential lock: slightly apply brakes to make both axles turn.

"What if you install FIVE flywheels" ... *installs FOUR* "Thanks for watching and subscribe" In Soviet Russia Four is Five greedy gopnik

Redline the RPMs, and dump the clutch, in the snow.....wheel spin for days😂😂😂

When they went to standard hardware bolts for the four flywheels, I was laughing and wondered what they would put in for protection of the flywheels flying off the engine. Instead, they use a hammer to tear out the existing floor so that there is even less protection. When racing, there was an incredible difference between the 20 lb., 15 lb., and 12 lb. flywheels as to stall off the line and the ability to rev quickly. To be putting on 60 lb. or more is insane, especially on a low horsepower four cylinder.

Maybe I'm hearing things.( flywheel comes zinging through the windshield)

So now to try the weight on the front crank pulley with the rear as is then without the extra flywheels, I really enjoy these they get you thinking and still very amusing.

And that's why you want your rims to be as light as possible too. They add rotational inertia to the car, similar to its body weight. When the clutch is engaged, that's exactly the effect you get. You could test engine sound this way because engines generally sound better when they accelerate under load. For the weird noises you heard, they should occur during normal driving too, because as long as there's inertial mass connected to the engine, it will run smoother than without. The springs in the clutch might allow some uneven rotation, but that's about it.

lol the pauses in the middle of sentences r hilarious "meaning that.....we had to.............shorten..............the prop shaft"

this is like mechanical battery 😁

I expected it to significantly smooth out the engine. Weird. Maybe see how low it can idle now without stalling?

Very impressive that the crank could handle the massive rotational mass.

Make a set of 'TIRES' out of a stack of large truck/ heavy equipment flywheels put together!!!!!! :)

Man, you do not want a fly wheel flying off, let alone 5 of them! It basically turns into a real life Metalman metal blade weapon from Megaman.

take a old lada change the engine timing, fuel ratio and make it run super rich, then replace the exhaust with a short pipe to make it backfire like crazy

Props to the guy adjusting the exhaust hose on the car "We may be crazy Russians but we like not to die."

I'd love to watch the summer edition of this video! It definitely deserves it!

Runs like an old non turbo diesel like a Volkswagon rabbit from the eightys

Timing chain is probably doing as much pushing as pulling.

It's like one of those toy cars that had a small metal flywheel in it that kept going forever once you got it going.

there is a science to this,race cars usually have very light flywheels,diesel trucks have extremely heavy ones,it's about energy storage vs how quick you want the engine to rev

do you reckon you can make a clutch out of 50 grit sand paper?

Some power generator are started by a mass that is always kept in motion... This allows to minimise the amount of batteries needed for no-break power systems, since the engine is reaching it's ideal revs in less than 30 seconds.

*[rubbing sound intensifies]* Russian mechanic: "maybe I'm hearing things. Let's add some more."

That flywheel is now a battery. Stores energy. Back in the early days there was a bus that had a “battery” that used that principle. Spun the flywheel to really really high speed and the momentum was used to power the bus.

These are the important questions in life. "what happens if I do this absolutely impractical thing"

Inertia..and inertia increases torque this will be very noticeable basic physics of movement.this channel teaches people without them knowing it,I love it carry on good work you do,lots of effort that you put in are appreciated by your fans🥊

Thanks for translating our Ruskie Brother. Empirical vs Theoretical. We need to do stuff and try things instead of trusting what advertisers say. That said, car makers really do their homework obv.

love your videos so much appreciate even more that you do english voice over your one of my most favorite youtubers thank you for the epic work you do

For a second I though those where flying wheels.

The bunch of flywheels looked like a wheel, how about making 4 stacks and fitting them as wheels.

My 1969 CJ 5 with Dauntless V6 came with a factory 50lb fly wheel which helped the engine perform more like a tractor at low idle speed

this was an awesome learning moment.. this means adding a lightweight aluminum flywheel should be a decent bolt on performance mod, depending on what you are putting it in..

Attach engine to a stand with the fly wheel and start it

Probably building lunar levels of vacuum off-throttle in 3rd

A flywheel is, in effect, a "mechanical battery". The increase in time it takes to build revs, is synonymous with "charging" it... while the slow decrease in revs, is the "discharging". Notice how he mentions that the car continues on the "stored energy". The "problem"... is all of the energy required to "spool it up".

When it snows so much you just casually say we just are used to running welded difs

Soo what if yall make it sieze up, with all that inertia it'll have to be insane

Russian cop pulls him over, oh it's you again, why bother. Anyway , what's your act today?

For drag racing on cars with limits on the motor, the extra rotational energy from heavy flywheels helps launch the car. It also gives a little extra kick when shifting.

Here in Norway there was a Rally Cross driver that used the heavy flywheel trick to make sure he was first out on the start line by revving up his 500+ HP Rally car and let it rip in second gear instead of first. He pretty much always was first in the start and in Rally Cross that means much higher chance of winning because the races is short.

I would like to see a lada engine. modified to run on kerosene, like a model airplane engine. Raise the compression and replace the spark plugs with glow plugs, then add a turbo

TRY THEM AS TYRES

Here in the states a company called Tri-County gear sells a weighted fly wheel for use in jeeps. It makes it so a four-cylinder engine in a jeep won’t stall out when off-roading.

The Energizer bunny of Ladas, it keeps going and going and going....until the crankshaft breaks. This one is the opposite of the time they ground off the crankshaft counterweights. Crazy stuff.

Would love do see a full throttle clutch dump on dry pavement, I wonder how hard the car would launch?

You should try to install like 5 gearboxes in one car

Its like a motocross bike and a trials bike. The trials bike has a heavier flywheel and is much more easy going. Motocross engine's are very instantaneous on throttle, but trials engine's are less so. As I expected, a more forgiving and tolerant drive. I really love stuff like this. BRILLIANT 👻

How about putting a fly wheel under the car and make it almost as wide as the car. The fly wheel would consist of weights attached to springs. The faster the fly wheel spins the farther the weights extend. It would be a similar effect as an ice skater bringing in their arms when spinning and then spinning really fast. The ice skater would represent the wheels of the car. When the car is cruising at highway speeds the weights will be fully extended however when slowing down, the weights would begin to move back in toward the center of the fly wheel causing the car to want speed up when you're trying to slow down. Or when going up a hill take your foot off the gas and feel the car accelerate or maintain speed. You're going to make a great discovery accidentally. Keep up the good work.
