Dont get me wrong this is by far my favorite youtube channel, they could be makin way more money with the brains in that shop, but it wouldnt be as fun thats for sure
Back in the day in a communist country if you got the opportunity to have a car you kept that car on the road any way you can. It's how they have skills like this and that gets passed down. In a country like the US or Japan cars are much more disposible. My uncle who was a street sweeper mechanic and worked for the city and motor pool in the military HE had skills like this. Anyone working on regular cars in the US would just buy a new crack or a new car because they are so plentiful and available. A lot of these old cars you see in Cuba are like this, hardcore hack jobs but because of that they have no real value on the international classic car market.
Other than the possibility of the cam lobes and crankshaft throws being slightly off, the problem with the engine not revving lies in the intake manifold. It was designed for a flat plane crankshaft, and it was manufactured to flow well with that crank setup. Make a pair of manifolds with two runners each and a single carb on each manifold. The engine will rev until the crank falls out.
The intake has four individual runners. It is not going to make any difference if its a flatplane or crossplane engine. It doesnt rev because the crank- and camshaft are complete junk, literally welded together from pieces. They should be turned and balanced, and even then you're missing a balance shaft, which is going to be a pretty diffcult issue to solve.
@@CatrikI agree that the intake has 4 individual runners, but it is fed from a common plenum . The center two cylinders would run rich, because the carb is directly across from them, and those runners are shorter, so they make those runners smaller in diameter to lean the mixture. The outer runners are longer and of a different diameter. They were designed for that particular firing order, which has dramatically changed, which will make a different intake manifold design necessary. There are cam grinders that make a cam for Ford 351W engines to change the firing order. More horsepower results, but the stock intake manifold must be changed or two cylinders (I don't recall which two) run rich with the new firing order.
@@Catriknew engines make camshafts like this with the lobes simply pressed on. These ones are at least solidly attached unlike a lot of brand new machines
The cross plane crank in motorcycle applications was intended to help the drive tire have improved traction by controlling the power pulses released by the engine. Instead of the power pulses with the standard firing order assaulting the tire and making it harder to control, the cross plane crank allowed a pause in the firing and this allows the tire to gain traction.
@christopherdesbaux5950 Triumph uses the same principle with their Tiger dual sport. Their triple has an altered firing order so it runs more like a big twin
Have never seen Garage 54 use a dyno before. Hopefully the guys (and gals) who are a part of G54 can get themselves a dyno. Would love to see the HP and kW of each car.
It’s a lot of them already done on rus segment of youtube. Even 700+ hp ladas existing. Niva, on factory engine with turbo that beats nissan gtr, and many others. This guys do things that never been done before.
@@Hi---There almost every experiment they do would be more fun if they had more than 70hp... They make neat things but a Lada can barely get out of its own way...
@@mac24seven several years ago they put three engines straight. It was fun indeed. 6 cylinder engine, welded from two 4 cylinder. I showed more power… and been shown to neighbour auto repair shop. Reaction was really fun. 8))) 0_o ??? 6 cylinder lada engine???
@@mac24sevenMaybe a Toyota engine in a Lada could work. Japanese reliability + Eastern European ruggedness = perfection. All the Lada needs is some German interior.
Y'all are amazing cobbling together a distributor for a custom crank an cam and it firing right over is on another level...if garage 54 said hey we're gonna build a diy stealth jet I would genuinely believe they could do it 😅😅😅
Damn!!!! Sounds like a Small Block Chevy!! Sounds incredible! If you just heard the sound, and didn't look under the hood, you would swear someone stuffed a V8 in that thing! I bet you guys have every Lata withing a 50 mile radius shaking in their boots! None of them want to wind up in your shop!!
Hahahaha. Yeah I thought they vacuumed-up every old lada in the state; and have their eye on the next one too. They must have a yard full of all their freak creations !. Hahahaha
Hahaha! The old cross-plane crank I4. Yamaha did that for the R1 motorcycle a few years ago. The noise is the same as that of a V4 (such as my VFR800). The sound of a V4 or cross-plane I4 is fantastic! Welcome to my world whenever I get my bike out for some play time! 😁
I wish it was, but this video also shows the hard reality why it (Almost) isn't used. It requires balence shafts and increased complexity which means high cost for the performance it provides. Not viable for automotive use. 🙁
This is the greatest Lada engine mod yet. That sound is incredible. Sounds so much like a V8 I can't believe it. Had to keep rewinding it and listening to it. And the revs those welds handled is impressive.
You might want to actually look at Lada prices in the USA before you say that... They need to be 25 years old to import, and good used examples of that age are not exactly leaving Russia in huge numbers. By the time they're shipped here by a used car dealer specializing in that type of import auto you're looking at minimum $30k.
I've been waiting for a different channel to finish their version of this for years, and these random Russians just go and DO IT in a frickin weekend. Hats off, fellas. This is badass.
You can check some of their previous shenanigans like plastic pistons, transparent crankcase, or beer cans for tires. I'm not sure if they had been dubbed in English though...
I think I would be awesome to take this to the next level. Next time have a machine shop do the cutting and balancing anything out. Then put it to a long term test!
I guess I’m referring to an extremely advanced machine shop that can truly balance cranks, use dial micrometers to clock and rotate the cams and crank shaft. Basically actually build the engine like they were factory or aftermarket parts that are perfectly clocked and balanced. I love that they do stuff like this. But taking a flat plane crank to a cross plane with no adjustments to the counter weights on the crank is going to cause huge vibrations, like what broke the bell housing. It would be super cool to see a “built” cross plane Lada engine that they could put on dynos and take racing.
@@joesutton3181 there may be easier ways of fixing the broken bellhousing issue, such as using a gearbox for a larger engine, using longer bolts and a reinforcing steel frame, using a dual mass flywheel from a tdi etc.
I have told them this before, a 5 cylinder diesel Lada with a modernized interior, GPS, fancy dashboard and new paint job. A luxury Lada with 800 km of range. But Garage 54 has to get through other people's requests. :) I don't drive, but if I did, a modernized 1980s Lada with bleeding edge technology and 5 cylinder modified diesel engine inside would be my dream car. Economy cars are the best.
@@thatguyalex2835 they not do ordinary things. Just swap MB or BMW diesel in lada quite common . A lot of Nivas swaped on diesel. Make 5 cylinder, after they did 6 cylinder and convert to diesel. It will not go 800 even once. Just conversion petrol lada engine in to diesel is already done.
So a 4 cylinder sounds like a v8 and a v8 in the same configuration sounds like a 4 cylinder😂 Absolutely love you guys. The creativity and the talent you all have that goes into all of this fun stuff is amazing👋👍. Greetings From Norway😊
LOL, it sounds like an old V4 Wisconsin industrial engine. I didn't think that a cross-plane would have disturbed the normal 180 degree firing order, but I guess it does. Pretty crazy stuff!😆
@@gabrielv.4358Hah hah, thanks. I wish I still had mine. I've been reduced to an '85 Toyota 'soccer mom' van. Same general feel, but it ain't a VW bus!😄
I love your curiosity and your willingness to go through complex procedures to test your ideas. You are a talented group of gentlemen. This is always an interesting place to visit. Thanks for recording.
The advantage of Yamaha's cross-plane arrangement, as i understand it, is to stack power stokes so traction will break momentarily when traction is near its limit. This is useful (as feedback) for motorcycle riders as they (we) apply throttle when exiting a turn to accelerate. As the rear tire begins to untermittently slip, the rider can optimally modulate power for the conditions. It seems to me, this mod would only help in a car; 1) if your engine has enough power to break traction, and 2) the car doesn't have ABS/traction control.
The reason yamaha used the crossplane in the r6 was to change the firing spacing. Normally, the spacing is even but with the crossplane you get 2 cylinders firing in quick succesion then a breif pause the idea was the 2 quick pulses would accelerate you out of the corner while the small pauses give the tires a break keeping from exceeding the grip of the tires. Quick edit: This is why the cross plane motors were called big bang motors . The 2 quick power pulses acted as a bigger power pulse.
exactly, except it was the R1 not the R6. It gives the rear tire a chance to keep traction when on the side of the tire. It was used on the M1 yamaha in Motogp, where they get 300 hp out of 1000cc engines, no turbos, bore limit of 78mm and limited fuel and they stlll make insane hp
Bro speaking like it takes an eternity for 2 quick succession bangs inside an engine, and that the pause also has any significant time delay to do anything of whatever bullshit he tried to describe. Where dafuq do these people come from? 😂😂😂
You guys are making science with old Lada platforms never cease to amaze me, pure quality content at finest Recreating the Yamaha's crossplane crank for Lada engine is a job for mad geniuses Next time try with a custom made billet crankshaft with full 8 counterweighs to reduce vibrations and NVH levels to the minimum acceptable levels, a custom cam with better profile will help for revving the engine up to stock redline or better performance, test it in a dyno and you can show the results These videos are fun and educational at best, keep this great work
Very neat video. I know this comment is being posted to the video 2 months after it has been posted online, but I do have one suggestion for the balance. Besides Yamaha, GM produced an TON of crossplane I4s in the form of the Detroit 2 stroke diesel engine. If I'm not mistaken, they balanced those particular engines mainly using the crank itself via the counterweights. Cylinders 1 and 4 have counterweights while 2 and 3 don't. If this is implemented on this engine it should smooth it out to some extent, although due to it being 4 stroke and oddfire, there is nothing that can be done to make it run without vibrations from the uneven power delivery. The balance shaft in the Yamaha basically is composed of similar counterweights to take care of the primary imbalance, while the crank has counterweights for each cylinder. I think their solution was chosen to allow for the engine to rev quickly.
EXCELLENT!! You've answered a question I've always had since Yamaha came up with their cross plane engine for their motorcycles. It really does sound like a small V8. I think a change of exhaust tailpipe would really make a difference to the sound 👍
Much respect for the upload fellas, awesome work, very enjoyable, thank you! And thanks BMI Russian for the voice over and translation, big love from the UK.
As I understand it, the Crossplane engine was designed with the concept that, on a motorcycle, there is a long section with no firing which allows the back tyre to regain grip so the bike handles better at racing speeds
For the race application you spoke of. You wouldn’t reduce engine vibration. The standard online 4 has acceptable balance already. The Yamaha R1 cross plane has balancers that were added for the cross plane set up that weren’t on the previous motor. Those balancers try to equal out the new inbalance of the cross plane. As the standard Lada engine doesn’t have those balancers I would expect there to be more inbalance with this set up. The point of the cross plane 4 in the Yamaha bike is that all the bikes had more power than they could use in MotoGP so they sacrificed engine power for better acceleration out of the corner on the limit of the grip. The “lumpier” drive out of the corner gives the rider better feeling adding to the control of the drive out of the corner.
This is really sweet as well as the work put into thinking this all out, well thought out and it worked . outside of ballencing the moving parts this was unique kudos to all of you .
literally just like cutting n american V8 in half, and putting it in a lada. got that same sound. and imo, small displacement V configuration engines with multiple cylinders and a cross plane crank, like a slant six from an old muscle car sound good.
Chevrolet did the opposite of this quite a while ago. They used a 90 degree V block and a 180 degree crankshaft instead of a standard 90 degree crankshaft. They called it a flat plane crankshaft, worked well. You can find a lot of information on it via internet.
Balance shafts would have to be redesigned. Fluidampr would help, and, as mentioned, twin Weber 2-barrel carbs would even out mixture at each cylinder.
Very cool. Just wanted to set you straight on the original intent though. It certainly wasn't for reduced engine vibration as you suggested, these motors vibrate much more than a traditional crank and so they have balance shafts in performance applications. The original idea came from the old 2 stroke Honda 4 cylinders in Motogp in the 90's I think, the idea was to spread the engine pulses out to increase edge grip while leaning in a turn. Motorcycles have a very small contact patch and the constant firing of a traditional layout punishes the tyre under power. The engineers theorised if you have a large gap (270 degrees) between the last pulse and the first you give the tyre a break. It worked to great effect. They affectionately called it the "big bang" engine because of the distinctive sound. Yamaha still uses it in Motogp and have the only 4 cylinder road bikes with the cross-plane crank. It seems to be hindering their ability to match the other brands at this stage as they can't seem to get the same sort of top speed. As the layout is naturally unbalanced, higher RPM is likely harder to achieve while maintaining reliability. The stresses at 20,000 rpm are unimaginable.
Good effort! You are half way there. Now do one in a different way : cut the crank in the middle only, and rotate one half 90° away. You will see that Yamaha has done it wrong. This way, it can operate without balancer shafts, same as an URS engine.
My first thought listening to the intro pitch was thinking a custom ground crank and cam then saw the rapid prototyping and loved the solution it might not last for 100’s of Km but works for the proof of concept
A long anticipated episode and one after my own heart. Still cant beleive the welding skill of these guys, Lada must use forged steel (ie not cast iron) in thier cranks for this one to even survive being cranked to life (after chop and weld), let alone the lumpty dump torsional vibration it is subjected to with this firing order. One question answered here is how much low rpm idle vibration there is in a X-plane 4 without balance shafts. Best episode yet and many thanks for playing out a dream. In a dedicated production car all issues would be solved using a 270 degree crank boxer 4 layout, and sticking to a heavily built manual FWD transmission. There's absolutely no advantage to be held in this power dynamic accept acceleration and that head turning sound.
Well done guys! Sounds beefy. You should get a machine shop to make you a billet cam, billet crank, and some balance shafts to match and then strap a turbo on it 👌😎
Finally! Been waiting for this for years ❤ (A four cylinder with 90 degree crank will sound similar to a V8 due to the uneven firing order creating that epic beat)
Sounds like a racing motorcycle or a formula one car. All up in the top end , the balancing is so far off from the welding and cutting it with self destruct for it is going to eat the bearings out of the crank and rods. The balancing was so apparent that the bell housing went right away from the excessive vibration, but it run like a formula one car until the balance or lack there of destroyed it. Need to plan, blueprint and balance the rotating assemblies for the bottom end and value train. Top end will be almost impossible but it could be done with work 😢 and time. Good luck on your new adventure. Bravo and congratulations on your achievement with the video. Very enjoyable and educational for someone wanting to learn and try something. God bless you all and enjoy your day today.
