But the difference is that ECU wouldn’t let it over-rev and destroy the engine. For 99% of owners who want to fire it up and give it a run and show their buddies it’s fine. The motor isn’t making anywhere near its full capability, look at the exhaust ports, nothing is polished or ported, they’re tiny. I’d bet the inlet is exactly the same, and the runout on the crank is crazy, probably just running a brass bush in the back not a true bearing, they’re built to a price.

[@montecorbit8280]

For an engine this size, the better solution to dyno it would have probably been something similar to what Torque Test Channel does When measuring watts on drills and grinders and the like. The hook it directly to an electric motor from a BattleBot and then measure how much electricity the motor produces, (FYI: electric motor run in reverse = generator). They have half of the video telling what they did and how they did it, then they upgraded it somewhere along the line. Try doing that next time, they also have a dyno rig to test torque for the equipment they test, but that brings the electric motor to a stop....that would probably be bad news for a gas engine and probably should not be used....

Cosworth?? thats a joke. I worked on brits sometimes they do good things by accident but they have no idea what quality control means. If you wanted a well built micro motor you would got to Honda they already did multi cylinder tiny engines in the early 1960s they built a 125 cc 5 cyl. that got around 34 hp naturally aspirated .But they had Japanese engineers and Sochiro Honda overseeing a formula racing engine not a chinese novelty. the poor ignition was probably a cheap safety device to prevent the engine from grenading at above 2500 rpms.

[@ianhussey5036]

Great demo, loved the sound with the headers and new ECU.

[@kevinkline3491]

The fact that you can hold the throttle wide-open and the engine basically self governs itself, tells you that the airflow through the engine is highly restricted. The porting in these doesn’t really scale down compared to a real size engine. They’re actually quite restricted port wise in reality with the proper porting, it should make quite a bit of power theoretically as long as you can have an ignition system that will match the RPMs. As you can see most of that ignitions that they come with really aren’t up to the task.

[@WarpedYT]

actually i forgot to include the clip but i rev limited it with the ECU to 9000 so I could focus on only the dyvo pull, in all the future videos im going to try and include all those points, but yeah the airflow is restricted none the less

[@cosmicraysshotsintothelight]

Then one needs to consider the cam as well. These scaled down engines have a different set of problems related to the scaling down of the flows. So there would likely be a very low amount of exhaust scavenging, and likely a low cam lobe overlap, etc. Valve openings cannot be before top dead center because there are not the same fuel/air "slugs being moved around and they would close at bottom dead center because there would be very little inertial push to add to the incoming fuel air charge so no reason to hold a valve open past bottom dead center. In other words, even if constructed exactly as the ports are on a real full sized engine, the flow results would vastly differ. This engine will produce, but not likely put out huge amounts of power due to efficiency limitations of the intake and exhaust cycles flowing through those tiny passageways. Which is why I said that using a gas instead of a fuel droplet/air mix might get a better yield.

[@Turavin0]

I'm sorry to tell you that this guy's testing methods were so bad that we still don't have any idea how much horsepower this engine produces. To start, he set out to measure the torque the engine produces in ft-lbf by using a 6-inch (1/2 foot) lever arm on a pound-force scale and then dividing the result by 2 instead of multiplying by 2. The next incorrect bit was he used the force required to stall the engine to calculate the torque. If the engine was capable of making that torque, it wouldn't have stalled. 1 horsepower might still be right, but we can't determine that from this video.

[@45johngalt]

I was guessing about the same as my knock off 49cc Honda 4 stroke single cylinder I use on my bicycle makes about that much as far as I know, might be more like 1.5hp

[@crissd8283]

​@@Turavin0I think divide by two is correct. If the arm was twice as long (12") the force would have been half on the scale. So to get the same number he should divide by two. I agree, it certainly isn't a real dyno run with a full sweep and such. However, I feel he was trying to get the torque while it was running using the camera. I think it was a decent attempt without going crazy with a custom dyno.

[@Turavin0]

@@crissd8283 Let's break this down barney style. Let's say you have a ratchet that you're using to tighten a bolt, and that ratchet is 2 feet long. You're pushing down on the end of this 2-foot long ratchet with 100 pounds of force, how much torque are you applying to the bolt?

I'd go with more durable material and connect them according to the cylinder timing so you get some scavenging effect too - silent blocks for the mounts AND the dyno leg so it pushes into the scale more consistently Other than that - if the gasket wasn't blown, my mind was.

The exhaust ports look about 5mm. That's a total port area of about 200 sq mm, equivalent to a single port of about 16mm diameter - very rough I know. The stroke on these engines is about 18mm and the total is around 50cc IIRC. Now 18mm stroke is about half that of a 50cc single, so 8000 rpm is equivalent to a 50cc single turning over at 4000 rpm, which is quite low. The usual calculations show that, allowing for the total piston area, the engine should be equivalent to a 50cc single turning over at about 5000 rpm. This means that with all the complexity this engine is quite a bit worse than a single cylinder 50cc engine like the ones produced in millions by Honda, and that isn't all friction. The total port area is adequate for well over 4BHP. The conclusion is that the valve train is probably very poorly designed.

[@mikesmith1290]

I noticed that the HP was decreasing as more headers were falling off. Each dyno run had fewer headers than the previous one. Exhaust systems do affect HP. Maybe those headers provided just enough back pressure to increase power?

[@TheBeeMan1994]

Back pressure doesn’t make horsepower lmao, it robs it. Real headers are designed to pull vacuum on the neighboring exhaust runner to help evacuate the exhaust faster on the next exhaust stroke. This isn’t a 2 stroke that requires a tuned pipe for backpressure, 2 strokes and 4 strokes are wildly different. It was putting out less power because it was getting hotter, and the rotating assembly, pistons, etc were expanding and causing higher friction, you will see this in full size gas engines when they overheat. Those “headers” were doing nothing but directing exhaust away from the table

[@cosmicraysshotsintothelight]

It would not be a "back pressure", it would be a "scavenging" reduced pressure allowing for better flow and cylinder evacuation.

[@FancyPants43]

Was it just me, or were the welds on some of the headers melting off?

[@MigotRen]

could you put on some 6 into 1 headers on this with expansion chambers. i wonder how close this coudl get to f1 sounds. there is a great video on how this works by maisteer "How F1 sound is Made"

I think that's the next step, I do have another V12 up next right after this one, yeah I watch his channel actually, the videos are really good but very strange which is sometimes refreshing on KZbin.

[@cosmicraysshotsintothelight]

​ @TheBeeMan1994 Another consideration is that the brake is applied at a specific distance from the crank center. THAT is the "lever" applying the force against the crank. Then, the output arm is a lever that gets torqued against by that brake disc, at that brake pad distance from the crank. I think this also may not be being factored in. But one supposes it does not matter since the output arm is measuring (applying) the force properly to the force transducer (scale). And that arm length is all that matters. Choosing whether it doubles or halves is the question. The same torque yields half the torque on the half length arm, Or is it double the force. Do we half the reading or double it? Applying force a double length arm applies double the force, which is why a breaker bar exists, but when reading torque applied to an arm by a hub, the same torque output at the hub applies what force to a one foot arm and what force to a six inch arm?

[@mixxedboyybuilds8273]

​@@cosmicraysshotsintothelightsame question I was having, the torque should've been doubled before plugging it into the horsepower calculation, not halved right? Since the lever was 6" instead of 12".

[@mixxedboyybuilds8273]

​@@cosmicraysshotsintothelightso I actually just asked Gemini AI how this equation should be constructed 2 different times in different ways of wording the scenario. I have to say I stand corrected, the scale reading actually does need to be halved to get the ft lb measurement when using a 6" lever instead of a 12"/1' lever.

[@mixxedboyybuilds8273]

Now that I think of it it does make sense though. Sit a scale on a table, use a 6" pipe to press down on the scale with the end of the pipe positioned horizontally, repeat with a 12" pipe. The scale will read about twice as high with the 6" pipe due to having more mechanical advantage ("about" because of human error), with the 12" pipe leverage would be working against you instead of in your favor due to the end of the lever being farther away from the pivot point (your hand).

[@direfox240]

*I was wrong. Original comment left as is, correction/update after. TLDR Divided. Should have multiplied. I believe the math is off. Force exerted being measured at half the lever length should be a division by 0.5 not 2. If I'm right it should look like this for run one. 1.875lbs / 0.5 (6inch arm) = 3.75 ft-lb 3.75 x 7,000 = 26,250 / 5,252 4.9981 Or roughly 5hp depending on where you round it to. *update explaining why/how I was wrong Seeing a whole number in the math for lever length correction got me since lever was shorter than 1ft. Plugged in the correction as is. But that is opposite of what should be done. We are working with force on lever FROM torque not force TO MAKE toque. To find torque that made the force, divide by lever. 1ft for ft-lb, 1meter for Nm 3ft vs 1ft vs 0.5ft(6 inch) math for 10ft-lb would look like this. 10 / 3 = 3.33lbs 10 / 1 = 10lbs 10 / 0.5 = 20lbs To find torque the force is making, times by lever. 3ft vs 1ft vs 0.5(6inch) for 10lbs from lever would look like this. 10 x 3 = 30ft-lb 10 x 1 = 10ft-lb 10 x 0.5 = 5ft-lb Vid math is 1.875 / 2, which is the exact same as 1.875 x 0.5 So yeah run one is 1.25HP

[@ryancawdor9381]

I also think you are correct. I did dyno testing and a 6in bar is half a foot. It has half of the leverage so the force value needs to be doubled to get to ft/lbs.

[@tomclanys]

Torque is force multiplied by distance (of the arm). If you have half the length of a foot, in this case 6 inches (god I hate imperial. Use metric please), you need to multiply the force x2 to get the same torque number. If you want to know the force which would be exerted by a twice as long arm, you divide the force in half. So 1.9lbs * 6inch = 11.4lbs-inch. Now into lbs-ft -> 11.4lbs-inch *2 = 22.8lbs-ft.... now I'm confused, why the f* divide by 12, why not 10? Just why. Let's start over. Again: 1.875lbs*6inch is the same as 1.875*0.5ft, because you have to take into account the unit change. Here, in the *0.5 is the division because you have the arm that is half of what we need. Force reduces with length of the arm. I think Warped was right after all in his calculations.

[@MilesPrower69420]

this is what ive been saying, mat was wrong, yeah its 5hp

[@Cyrix2k]

That's what I thought as well... 6in arm means the force measured needs to be doubled to get ft/lbs.

Neat! I have been to the IC model show in Detroit a few times, those guys are nuts! Their engines are scale models. I heard a Riggle 4cyl 4 carb motor in a car that would hit about 15k rpm in .5 second! Those guys made a V12 Mercedes running car from the blue prints that was about a foot long and had working hydraulic brakes and functional gauges! That motor is hurt. It should only have about .0005" to .001 main bearing clearance I'm guessing. On a motor that small .001 difference in how high the piston comes up will make a huge compression difference. Looks to be in need of a head porting job, tuned headers and at least one more carb. The highest scale reading will be peak torque not peak H.P. The setup on the back is WAY too heavy. Make the brake stand-alone and run a shaft with Love Joy style rubber joints in it to isolate load and vibration, then mount the engine in a rocking cradle and measure torque there to eliminate loss thru joints and bearings. I wouldn't expect it to live long. Keep the water circulating after shutoff. I'm very surprised the crank may still be in one piece! (They can run broken sometimes) exhaust valve, may be next issue. great job! Always wanted to see one pull.

This engine stops revving at 10k rpm as delivered without any load on it. That means that the losses required to turn the engine (pumping losses for intake and exhaust, water pump, oil pump, bearing friction) consume 100% of the power that the engine is producing. At max speed the engine would be producing zero horsepower otherwise it would still be accelerating. You measured 1 lb 14 oz on the scale to stall the engine. If the engine could be stalled by that amount of torque, it isn't capable of producing that amount of torque. Your force calculation is also incorrect, because your lever arm is 1/2 foot, meaning you need to multiply your force output by 2 to get the result in foot pounds.

Wow it is night and day difference on throttle response when you put that chain ECM on! Amazing

[@raymondeemon125]

Before it failed the main reason you lost power is because the exhaust fell off and the imbalance of the intake pressures and exhaust pressures need to be managed to squeeze some power out of it. Also with small engines like this the exhaust pipes help to dissipate the heat from the engine. The combination of that and redlining it over and over in a short time just added to it's failure. I bet with a better carburetor or some type of fuel injection plus a more efficient exhaust system would result in the best performance that thing could give. I work on small engines and these toy ones. They really don't like or cannot handle fast Revving. The seals they use for them are not ment to handle that kind of instantaneous pressures from that high of an RPM. I know for a fact that engine could put out a atleast 3 hp or something close to it. You should try to make a R/C car and put this engine in it! It would be a beast. Even better! make it a POV R/C car with a V12 engine! That's a video I would love to see.
