Bro - 8:11 I knew I would see this ..to be honest - I hated these engines straight out of the first notice- for many reasons ..one they were originally made for a minibike and a fail attempt at that.. Too wide- making the balance dangerous for a little kid along with top heavy- the aluminum is very poor quality the plastic gears still a bad idea .. But if you use only 1 supercharger you would have gotten at least 6 psi to 8 maybe ..the 2nd one added drag.. Not actually increasing the "compounded pressure" I love your channel and you are by far a better engineer than the makers of that engine - ways to fit the problems at hand (the metal in that engine will loosen its form because it's like cheap Chinese steel ..it has an extra mix of bad fillers causing the metal to bend break distort and the weight will warp and shimmy ..ok the overheating problem - you and I both think outside of the box ..maybe I even do it more but you managed to put alot of great ideas in to works *-applause-** so arctic cpu thermal paste could be smeared all over it .. Forcing the temperature 🌡 down ..i use it on heatsink it drops my cpus from 198 degrees to 135 - running a robotic automated program constantly processing for days on end - use it itll work there to .. You need a fan blowing on that engine itself ..anything with the force or a cool hairdryer is enough to get your heat down.. The balance in those pulleys and parts are whats the major problem - if you remake that engine using your own 3d printer and metal you'll come out much better I'm positive.. Be safe Bro! ❤- *Wonka*

[@233kosta]

When you run two stages of boost like that, you need to size your compressors accordingly. They can't be identical. When they are, either the first stage is overflowing or the second is starving. The first will necessarily need to be bigger than the second. I've run some numbers for you: - The engine displacement is 14cc - Maximum rated speed is 13 500 rpm - Total volumetric flowrate (ideal) at that speed is 1575 cc/s (call it 1600 or 100 ci/s or 3.34 CFM). You can't fill the cylinders that quick, but that's the goal anyway. - Your compressors have a pressure ratio of about 1.68 (10psi overpressure) - Assuming adiabatic compression (no heat loss), that means a volume ratio (inlet to outlet) of 0.69, or sucking in 1.45 times more air volume than what comes out. You'll obviously lose some heat, but this should be close enough - This means that the second stage must suck in roughly 2300 cc/s, which means the first stage must be able to supply that at its outlet - Assuming the same pressure ratio, that means the first stage must be sized to flow about 3400 cc/s at its inlet You also need to mind the heat here. Keeping to the assumption of adiabatic compression (because the air moves fast enough to lose very little heat), and assuming your workshop is at about 20°C (68°F), your first stage outlet temperature will be about 67°C (152°F) and your second stage - 121°C (250°F). Obviously some heat will be lost to piping/environment/etc, but at those pressure ratios your cylinder inlet temperature will still be upwards of 100°C which may or may not be too much for the engine. I'd check with Toyan. You might need intercoolers to protect it (either at every stage, or just before the manifold). If you do, it's worth recalculating the sizing for the compressors, because the total volume ratios will change.

[@233kosta]

@jesse james I don't, but perhaps I ought to - looks like good fun! I'm an aero engineer, we used to do these sorts of calcs for jet engines just for fun at undergrad ;) In fact I'd enjoy helping out with his jet engines more if he's interested, but this stuff needed much less information from him to put together. These days I mostly do advanced modelling for work, so going back to basics on side projects like that is quite enjoyable. As for electric motors, I know they spin when you apply current :P Don't they use them to start jet engines? Joking aside, you can get some pretty cool control systems for those, and if it's a standalone commercially sold unit you should be able to get a data sheet for it which has performance curves, power limits, thermal output, etc. And if you have a mystery motor (or its data sheet is barren), they're not too difficult to characterise, so you know exactly what you're dealing with.

The "compound" idea is flawed; the pressure isn't additive the way you're calculating it. That's why you're getting so little pressure overall. It wasn't the boost pressure pushing out the intake pipe - it was the vibration. You have a bad bearing in your idler pulley. And you're running your fuel mixture way too lean, which is why your engine temps are rising so fast; your "increasing the air charge" isn't all that you need to do!

One thing. For compounding to work the first supercharger needs to be bigger at the same RPM or be the same size while spinning faster. Because right now the second supercharger is creating suction at its intake which completely destroys the boost from the first supercharger while creating more heat than a single charger setup.

[@noahpaulette1490]

If I am not wrong he could also run a different sized pulley on the first stage for more rpm

[@daemon4470]

the point of this video is to destroy the engine.

[@pw383426]

Incorrect. Superchargers produce positive atmosphere, it can be rated in cfm, cubic inches, liters, several ways. For every rpm the supercharger turns it creates positive atmosphere displacement. Compound simply means 2 or more parts doing positive displacement. It's the same concept of when people used to stack 2 roots style blowers on top of each other, they would have the same positive atmosphere displacement even if they were side by side. Superchargers are much simpler than turbos in that aspect. The only problem I see in this setup is if the first supercharger inlet I.D. is enough to flow the amount of air required by both superchargers

[@orppranator5230]

Daemon No it’s to make as much power and boost as possible, and not give a shit if it blows up the engine.

[@anonym3017]

@@pw383426 let's go through this. Superchargers don't produce positive pressure. They move around air so that it can't go back. If you connect one to a long open pipe ( or a mine which is what the things were first designed for) you'll find that it isn't prodicing any pressure. if you connect it to a pipe that is being sucked empty at the same rate as it's filled (for example by another supercharger of the same size turning at the same rate) it also won't produce any boost. Now lets use some number picked right out of the air. The first charger takes 10 liters and turns it into 5. the second one also takes 10 liters and turns it into 5. They are spinning at the same rate so they are sucking in air at the same rate. But the second one doesn't have access to an unlimited supply of air. It only has access to the 5 liters per second that the first one provides. So it pulls a vacuum destroying the boost produced by the first supercharger. so in conclusion the first supercharger needs a smaller pulley to actually be useful. which also happens to be what can be seen on every compound charged racecar that has ever existed.

[@zacharyevans5016]

AFR's are massively important to keeping the engine cool while running aswell. Fuel "cools" the combustion cycle. so a richer mixture may not produce quite as much power, but it will massively improve the temps you're seeing and how fast it gets up to temp. Super cool video though, these little motors are super cool.

[@tilldeathdoesmepart]

I know it's it's old video, but I came to say this as well. He's adding air but he didn't talk about increasing fuel. And the Temps and overheating seems like it was running very lean. Which is great for power but not for the engine

[@williamallen7836]

@@tilldeathdoesmepart Extra fuel is being added via the preasure reference to the fuel tank. As boost preasure increases the preasure in the fuel tank increases. Which in turn adds more fuel delivered to the carburetor at an amount directly related to the amount of boost. So it shouldn't be running lean at all.

[@Modna89]

I think you need to 1) shorten your coolant hoses and 2) increase the hose diameter. You have a lot of resistance to flow through those long little hoses. You can see when the bubbles go through them how fast the water is trying to flow. Fast water = lots of friction loss

[@garyr7027]

And faster the water flow thru the radiator means less time for the water to cool down, plus it doesn't have a engine fan. Also, I highly doubt this engine has a thermostat... a setup for disaster.

[@speeddemon1092]

A larger radiator wouldnt hurt, either. A cheap 120mm aluminium PC watercooling radiator is like $10-$15 on ebay, tops. A 240mm radiator would be around $20ish. A chunkier fan to draw air through it would also be needed. 3000-4000rpm Delta or Nidec fans would do the job quite nicely and aren't too expensive.

@@garyr7027 that's why in a car , there's a right way and a wrong way to remove a sticking thermostat to get you home. Don't just throw the whole thing out , you need to gut it like a fish and reinstall it. Cut the pellet and spring part off , and place the disc back in , it's the restriction you need to maintain the right flow and pressure throughout the system. It doesn't necessarily need a thermostat, it needs to have the correct flow and pressure on the system.

[@garyr7027]

@@MrTheHillfolk fluctuations in engine conditions require fluctuations in the cooling system, only a operational thermostat can provide a constant cooling temps overcoming those fluctuations. Thermostat is nothing more than a valve controlling the flow to maintain a certain temperature. Sure you could run it without one, but without the proper cooling system setup, it'll either run too hot or too cool. In this case cool might be better since he damn near blew that engine up. In a real engine though, you really should have a thermostat, engines are designed to maintain proper temperatures for optimum fuel efficiency.

[@buildingracingvideos4714]

Looks like you're having fuel delivery issues as well. Using boost pressure to control the fuel pressure will never allow you to have full throttle. At part throttle you're building boost against the throttle blades, but on the engine side of the throttle blades you have less than the 3psi the superchargers are producing which is allowing the 3psi of fuel to be injected. At full throttle the boost and fuel pressure will be equal and you'll never get fuel to the engine. In simple terms the fuel pressure has to be higher than the boost pressure if it's ever going to work at full throttle. You have to remember those aren't carburetors, they are a very simple form of mechanical fuel injection and the fuel pressure has to be higher than the boost pressure.

[@RonaldMcDonald6969]

Yep exactly he’s running lean causing the heat.

[@kleetus92]

I have no idea why people insist on blow through systems. Unless he runs an electric fuel pump with a boost referenced pressure regulator to get that additional differential pressure, it will remain lean.

[@WarpedYT]

😉 ❤️. You're absolutely correct, but my goal for this video was to set up the entire supercharger system to show people that you can make boost with these little engines. You are dead on accurate everything you said, I have my list of open items that need to be corrected to make it 100% And before I use this engine for my project I think I'm going to do an even crazier modification..lol. I appreciate the feedback I love talking to people who know what they're talking about.

[@WarpedYT]

@@RonaldMcDonald6969 it's mainly running lean because the fuel pressure versus intake pressure versus how much extra fuel you need to meet the increased oxygen from the boost is a ratio that is not linear if that makes any sense. There are other ways to make this work, and I was only running half throttle here, can you imagine full throttle?

[@housertelevision9886]

You're having a fueling issue. Even the most efficient naturally aspirated engines run at several pounds under atmospheric pressure because of vacuum dilation from drawing in the air using a vacuum pulse. Since the engine is now running at 3 pounds over. It's actually seeing double the air. NA at high RPM is 14.5 - 8 = 6.5psi or less. This is why all but the most vacuum efficient motors see power loss at high RPM and why mid-history F1 engines could save fuel and still turn faster using high RPM NA grip. Then they survived the early turbo competition by running higher compression and using velocity stacks (like yours does). Giving them 7-8 psi (1.5 psi advantage). Remember this was before variable velocity stacks were invented and computer maping of intake plumes to time the refraction of intake pulse echo. Now your setup is 3 psi over atmosphere 14.5 + 3 = 17.5. That's more than double the air even with your velocity stacks power scavenging the vacuum pressure pulse in NA format. Now this is where the it gets complicated. Not only is there twice the air. Requiring double fuel to reach stoichiometry. People learned in the mid-history and before of racing to run richer mixtures well above stoichiometry for three reasons. 1.) Fuel cooling effect. The vaporization of the fuel draws heat away and puts it from the engine to the exhaust. Making better exhause flow, evacuation of spent gasses and cooling the head or intake gas. This also made more power by making the air charge denser alowing for even more fuel and therefore cooling. 2.) Rich mixtures turn more oxegen to CO2 and CO2 carries heat away with it. That why completely NO2 dependant drag motors use CO2 boosters to keep from melting pistons and valves. Enjoying a 2% power boost per charge and the ability to run even more NO2 and feul before structual failure of metal or meltdown/gauling occurs. 3.) A rich mix burns at a higher rate and continues to burn past the point of the exhaust phase. This creates more power and scavenging oportunities in maping the exhaust pulse reflection which then more completely emptyies the hot spent gasses. Which adds power by allowing more air and fuel to be added, but that also cools the engine better and the hot gas doesn't stay in place multiplying the cooling effect. Normally the forced air (boost) corrects this, but since you're running a naturally aspirated camshaft that effect is nullified. Using a stand alone fuel delivery method (a variable electric fuel pump) and increasing fuel delivery (injector pulse duration in larger engines) should correct this (firstly) and gain you the most benefit. Then change the cam. Then run an inline connected exhaust header. This will net 75% more power and keep you from overheating for 3x longer. Also allow close to an NA RPM ceiling. I really appreciate your CAD skills, but this is what you missed. Engineering doesn't teach this stuff. It's all learned through asking race heads who've been learning these tricks for decades. Can't wait to see you correct this and throw a rod for science. Get it on high speed please.

[@craigknight4836]

I was just about to say that. I might add that the dilation compression of the ventral cam is way too low under current atmospheric conditions. In order to fix that, he would need to triple the boost while adding fuel recovery in the midway valve tank rods. This will increase the power by reducing the power delivery in the centrifugal compression chambers. It’s just a thought but certainly worth a try.

I believe compound compressor setups don't just add x psi of boost each. The total output depends on the compressor's "pressure ratio". If a single compressor made 10psi of boost from atmospheric pressure, it would have a pressure ratio of 1.68 to 1. It's taking the 14.7psi of atmospheric pressure and multiplying that by 1.68 to get 24.7psi of total pressure (+10psi of boost). Now in a compound configuration, you would then multiply that total pressure again by 1.68 for a total pressure of 41.5psi (+26.8psi of boost). A bit more than expected. Awesome project BTW!

So at the very entrance there was like a superchargers screw that helped keep the turbo from surging (giving it a compound effect and therefore raising the possible boost) and after that screw was the normal radial turbo wheel. They reported improvements of about ~20% increase in pressure, if you would be up for the task of trying to build something similar, that would be awesome! :D

You should get together with JonnyQ90, he made a custom cooling setup for this engine, and he needs help with his turbo setup. Bad ass manifold man! That thing sounds awesome with the compound setup.

[@andrewyoung4473]

That actually sounds awesome, Johnny seems really good at all the details, like cooling and pulley design, fuel tanks, valve lapping, etc.

[@lukerosevear3255]

When using a turbocharger or supercharger with nitro fuel you will need to richen up the fuel to air mix. It will keep it cool.

[@jayjohns5653]

Yea; I was thinking the same thing

[@jamestrotter7852]

Compound turbochargers are used on petrol too, common usage is a small turbo feeding into a large turbo. Small turbo spins up way faster but only provides a little boost, big turbo spins up slower but gives massive boost. Helps to even out the power curve compared to having just the large turbo on its own in a performance application.

I know I was fortunate to have the first prototype.. not that that's anything special or anything 🌝. I do think I am the first one to make boost with a miniature supercharger.

[@krugtech]

in general the second stage should be the first stage size divided by first stage pressure ratio. If the first stage can make .5 bar boost, it should be 1.5 x the size of the second stage

[@veoverse4286]

I think you are right, if they are the same size, it wont work... Because the secound turbo can only compress so much air, that the first turbo delivers, if they are the same its useless😅

[@krugtech]

@@veoverse4286 using 3 of the same size with 2 feeding one would work

[@snakeballs8965]

If there's rpm left on the table you can still increase boost pressure. You're pulling in boost and then shoving it through another compressor, boosting it more. You just might as well have a bigger one that has a more ideal power range. Two fans means more friction and mass and whatever so it's less efficient than one big charger.

[@krugtech]

@@snakeballs8965 it all depends on where the compressors are efficient and working around that. a single stage is good to over 70 psi in race applications but staging is needed for real high pressures.
