See Thru Engine on Turbo Nitro and Dyno (How much HP does it make?)

[@CapeCodCNC]

You will never make boost with giant turbo on that tiny engine, there is not enough exhaust pressure to make boost. You need a teeeny weeny turbo like an IHI RHB31. then if it stays together maybe 15hp. but you will need a bigger carb like Carter #30 Carb. put a shock absorber on your scale.....

[@WarpedYT]

If you going to use that big of a turbo it should be a compound turbo setup. However that's going to a crazy build and you'll definitely want a thicker shield to stand behind

[@Fizzer99]

Add a boost gauge to see if you are actually making positive intake pressure.

[@WarpedYT]

That's a great idea, I can't believe I didn't think about that, oh wait a second actually I did that's what that little T is for on the intake tube, I actually think I forgot to put it on, but yeah I'm pretty confident this thing's going to make some serious boost and Power

Now do an electric motor comparison at 3 HP rating. You will find that the electric motor will increase in horsepower as you load it down beyond its nameplate rating. Something combustion engines are not capable of. Don't use compressor duty electric motors as they are already peak rated. Use a real 3 HP electric motor. A good one that is not too pricey is Leeson 120341, 3 HP wood working motor. You will need 220 volt supply.

Forget the turbo, just attach a leafblower to it, that turbo is almost as big as the engine, it was probably restricting airflow rather than improving it. Though i do love the spool noises

[@SuperEvo1990]

i've seen videos on that two guys putting two leaf blowers on there car. the leaf blower wasn't producing any boost that's because the engine itself has ability to suck same amount of air that leaf blower was producing hence it was doing no effect, but might be another thing for this engine which is shown in video.

[@deztructo123]

a leaf blower would have to work as a blow through, which would complicate the setup massively. probs best to persevere with the turbo.

[@CardboardSliver]

Mighty Car Mods did that with a Daihatsu Chirade and it made a few more hp.

[@FelonyVideos]

I agree. An oversized turbo like that will result in a loss of feed air pressure. That single turbo might work with 4 or more of those motors tied together and breathing through it.

[@FelonyVideos]

Although you can't use a leafblower in that setup. The fuel air mixture will detonate due to the slipring spark. It would explode the leafblower. Now, using an air compressor and pressurizing the fuel system would probably do the trick. Would probably destroy the bearings and explode the motor at about 9HP.

[@glumpy10]

I'm not sure the Turbo IS too big but I can gaurantee you the carb is too small to make max power the engine will produce. they are a horrible ancient design anyway. I used to Modify these engines and go from a 12mm carb to a 24 or 27 Mikuni and that made a HUGE difference with no other mods than a decent exhaust that wasn't made for a 5 HP flow rate. If the turbo is boosting it it probably wasting energy creating a vaccum as it were through that little carb. Remember, the carb is designed to flow enough for the engine rating, 3.5 or 5hp. It becomes a restriction when you are trying to get double/ 3times or more through it. Most basic thing of hot rodding was bigger carb and exhaust. Mikuni Carbs are good because you can change the jet sizes easily and they are readily available. If you don't know what you are looking at it can be bit of a challenge but black smoke is Rich, back firing is lean and read the plugs after a run till you get a nice tan colour and ajust accordingly till you get there. Until you get enough air and fuel in there, the thing will never really get up on the boost curve and make it's full power.

[@supersmalls]

He's in a workshop for goodness sake, just hook up the air compressor to the carb and squirt in compressed air, why waste hp on such a small engine to drive a turbo blade on the exhaust.

[@thelol1759]

supersmalls I’m pretty sure the hp loss from driving a turbo is negligible.

[@BrotherdMike]

I agree, it will need allot more fuel when it starts to come on boost, I would love to see you try adapt a bigger carb and get it to suit the turbo. Great videos, looking forward to more like this.

[@Diesel8290]

supersmalls that’s not how it works pal 😂

[@dco5055]

Plus the carb is not designed to work under boost. Clearly it isn't making any real boost or he would be pushing the fuel out of the carb back in to the fuel tank.

[@benspeedschannel888]

Turbo is too big I reckon, fit a wideband o2 sensor on it to help get the tune right 👍

[@korishan]

I was thinking the same thing. The turbo is too massive for that exhaust to spin up since there's only 1 cylinder pushing it. If this were 2 cylinders, it 'might' spool it up fast enough. Maybe go down 1/3 in size of the turbo. Hopefully after reading these comments he'll make the suggested changes and review the performance :)

[@WarpedYT]

@@korishan yes sir, my figured why not try it out, what I thought was super cool was looking at the high-speed footage during the last take, even though the turbo is spooling up you can see the individual exhaust pulses.

[@jrdn.lauren]

@@WarpedYT. I like your idea of getting injectors. I met a guy that had two turbos in series with each other. If you do find a smaller turbo maybe use both? I mean, why not... right?

[@WarpedYT]

Well This is a 27 mm turbo, the smallest that I can find online is a 25 mm. Keep in mind that this is the primary turbocharger of the sequential setup on the SL 65. If you have ever heard a SL65 Idle, you will notice that you can hear the turbo whine in the exhaust even when the engine is at 600 RPM. This little turbo is basically producing boost at idle when on it's original application, then at about 2, 000 RPM the transition occurs into the bigger turbo which I believe is a 55 mm, I'll have to measure it but yeah, for me 2mm isn't anything a little more fuel and timing can't make up for. And for the record I actually went to buy that little turbo, but I thought it was way cooler to take a turbo from a car and modify it to fit this engine.

Normally you would be correct, however in this case keep in mind I'm running nitromethane, if you add more fuel than turbo will spool, and also be red like a cherry on top, seriously. but in the next episode I'm going to compare this turbo setup to a proper smaller turbo setup and see which one makes more power, I'm personally curious to see what's going to happen.

Warped Perception, I loved the video. It shows a lot of thought. The home made dyno was the bomb. Point of trivia. I have a machine shop guru neighbor, who builds 3.5 Briggs, and 6.5 Honda single cylinder engines, for professional go cart racing. He's getting, the last I heard him say, 32 horses out of a 3.5 Briggs, and over 60, out of the Honda clones. 14.5 compression, big titanium valves, Mikuni carbs, wide overlay cams, and Methanol, with trick exhausts; fly weight aluminum flywheels. The Briggs are balanced and turning over ten thousand RPM's. The Hondas are balanced, and turning 12,000, to 14,000 RPM's. They make 100 mph go karts, if you have the nads to stay in them. I understand what you are doing, and why. It's fun, and something to learn. But, if you want to turn that little one lunger on, there is nothing like big tuned carbs, and compression, with breathing ability. Five thousand RPM's is just the beginning of making horsepower. As my uncle said fifty years ago, "If you want more horses, you gotta feed more oats."

[@WarpedYT]

Lol, that's a great story thanks, I can totally believe it. As for more horses from more oats that makes sense. My goal here in this series is to focus on variables outside of the engine design, pretty much I don't really want to modify the engine much but modify the variables if that makes sense. My original goal was to get the thing to blow up so I can move on with the engines that I'm featuring right behind this one, but this little Briggs is not cooperating so I'm just upping the ante as I go. Hopefully it blows in the next episode. Thanks for the story and thanks for the feedback that was awesome.

[@buckkidder6435]

Exactly, and I'm all in, on what you're doing. Two different goals, with different means. Those engines start with $$$. When you asked for bets, on horses produced, in the beginning, I said '75 horses,,,,, no,,,95' haha. I thought it would be exotically wild!

That's a lot of useful information actually. I saw that in the turbo version the intake of the compressor wheel is smaller when the carburator mounts on.

I thought about that too, but I think would stall/surge because the engine would never have enough flow throughput for it and would almost immediately cause detonation. A smaller turbo would be best, maybe like a MPS or small 4cyc turbo diesel turbo, the newer the better because it would be more efficient providing a better chance to spin up from an engine this small. Additionally that expansion chamber weirdness he has, leading down to a small pipe again that's on the back of the turbo wouldn't be doing it any favours with spool.

Wet vs dry boost; probably a very valid idea! As far as US production cars are concerned in the modern era, Studebaker used a carb box on their blown Golden Hawk in 1957, then starting in 1963, they used a special sealed AFB carb on their R2 engine, and reverted to the carb box with the higher boosted R3 and R5 engines. The latter ran over 200 MPH at Bonneville in 1964, all with a 5 liter engine. Pretty impressive for a stock bodied car at the time! They used basically box stock Paxton/McCulloch blowers. The R2 would make about 8 pounds of boost in bone stock condition, although some claimed more...but with all new parts I'm assuming. In a completely different situation, the 2 stroke Detroit Diesels all were supercharged, but later models offered turbos. In my own case, a Turbo 6V92 engine was speced at 350 HP at 1950 RPM. When the boost reached about 12 pounds, you could feel the difference. That was 552 cubic inches.

Really enjoy these videos however I think your measurement of horsepower is flawed. You are measureing horsepower at the peak observed torque. Engines almost never make peak horsepower at the rpm that peak torque is made. My diesel for instance makes peak torque (425lbft) at 1800rpm whereas peak horsepower is made at around 4200rpm where it is making significantly less torque. If one were to use your measurement method on this engine by snapshotting peak torque and calculating there you would only see 145hp. About half of the cars rated horsepower. I think to get better data points you need to devise a damping mechanism for your spring scale based dynamometer (look into cheap ebay motorcycle steering dampers) and try to get accurate torque measurements in something like 250-500rpm increments and plot the torque/calculater horsepower on a graph. This will give you a much better idea of any increase or decrease in performance. Again, love these vids and keep it up. Just trying to help you out.

[@rationalmartian]

Yes, engines make peak torque at a lower RPM than peak horse power. The lines on the dyno graph cross at ,I think, I'm a little rusty, 5252 rpm. Due to how the maths works with how they are calculated. As I say, I'm a little rusty.

[@li7in6]

@@rationalmartian you are correct. The lines cross at 5252rpm because horsepower is calculated by: hp=(tq×rpm)5252

[@JViello]

This engine will only rev to where he is measuring. If it would make X hp at 6000rpm, it would have gone there and he could have measured it. From what I saw the motor made more tq down low, but he measured where max RPM was. I could swear I saw some TQ numbers in the mid 20's on the vid at lower RPM which would have put this engine about 5hp and 8lb ft. Right in line with what it should do. These type of engines always make more tq than hp. I don't know if he removed the governor, but I certainly hope so. If not, that's what's holding him back as it tends to limit these engines to about 4000rpm max with an operational rpm of about 3600. It's actually acting very much like it does still have the gov on there.

[@StreuB1]

Likely blowing out the spark. Not enough energy once you go into positive pressure. They make stronger coils for those engines and I think you will get what you are looking for. With nitro (as I mentioned before) the equation is simple, enough fuel till the engine chokes and enough spark to light dirt. Once you add boost, you need more sparky. Love the build!!! :-D BTW draw through is perfectly fine for nitro like this. You need loads of fuel so you almost don't even need a carb lol. Just a hose in front of the turbo inlet and a flap in front of the inlet to limit the airflow. Nitro is a funny animal, and I do mean animal.

[@WarpedYT]

That's a good point.

[@dddzzzdddzzz]

I have made a few very high-compression engines work well even with stock ignition/coils and aged wires, just by reducing the spark gap. I ran a high-compression Super Gas bike for three years to good result just by reducing gaps from .028" down to .024"! Nitro doesn't like to stay mixed within the air stream, so may really limit how much fuel that can be fed in. You need a LOT(!) of liquid volume per unit air volume when running nitro. The upstream carb might be a problem because of this, and yes it is restricting the intake air by a lot. Any slight improvement in air flow rate will show about double the expected improvement, since the added exhaust energy will further help the turbo along, so improving the carb (or improving the exhaust flow from the ehxaust valve to the turbo) may show a disproportionate improvement in power. Two-strokes also work this way because their exhaust system supercharges the engine from the exhaust side. And another poster here was RIGHT ON about the intake manifold needing an elastic reservoir to allow pressurized air/fuel to build up unrestricted while the intake valve is closed! Adding a large "boost bottle" tee'd into the intake is needed here but becomes an explosion hazard that must be passively contained with a "blower blanket" strapped on. Anyway, the apparent "shortcomings" of this experiment are actually an educational feature of this video that makes people think and discuss what it takes to actually achieve actual benefits in the real world. An exhaust O2 sensor might not work on a setup like this because there will always be a ton of O2 in this engine's exhaust when running nitro and ESPECIALLY with a turbo added on. Excellent video.

[@loosewirewire7954]

Great work actually going out and trying to turbo a little 3hp. Most people just scoff at the idea and say it won't build boost. If you really want to build usable horsepower, however, you will need a smaller turbo. You are limited to your exhaust pressure by bore/stroke and rpm. The suggested IHI RHB31 suggested by Cape Cod CNC just might do the trick if you concentrate on keeping the exhaust temps and hot side of the turbo as hot as possible and keep the exhaust velocity as high as possible. You want the exhaust to keep a high velocity until just before the wheel and as hot as possible to take advantage of the rapid expansion of gases to aid in spooling up the turbo. The heat will do as much or more to spin the wheel than the exhaust pressure will with that small engine and modest rpm range. If your really stuck on using that turbo you could run it very rich to where you are blowing raw fuel into the exhaust and then lean it out and hammer it. You need the fuel in the exhaust to ignite until its cherry red. The heat might be enough to actually spool the turbo enough to gain some horsepower. Its not ideal, but its very effective.

[@dominicuri9102]

Have you considered twin-spark? Because the combustion chamber is odd shaped on a side valve engine, it might benefit from another spark plug to ignite the flame front more evenly thus giving a sharper kick - if it is possible to fit another one on the cylinder head.

[@aarontompkins5179]

I would like to mention I do believe that the horsepower was less on the Turbo System because the impeller was too heavy and actually became a slight restriction to the exhaust. I don't know if that's true but it's just a thought one thing that I had thought about is using a high volume of air discharged from something like a compressed air tank into the system that would give you a very cheap turbocharged but it would be very finite I don't know if that would be something that could be engineered to give it a forced induction

[@WarpedYT]

Yes you are correct, up to the point where the turbo spools and starts capturing heat energy it's just a restriction, but as soon as it gets up into its operating range the efficiency skyrockets. I'm not going to pretend that I didn't know that but I wanted to end episode there, that gives everybody a chance to put in their own opinions before the next episode. But yeah you hit it right on the money. Also with the compressed air I'm not sure, that might be something I can try out in the future but I know for sure it's going to have to be matched with the correct amount of fuel I was just going to start running lean almost immediately.

Try funnelling the exhaust down to about half the square area and aim it directly at the turbine. Make the nozzle go past the connecting flange so the velocity doesnt slow down before it hits the vanes. Its like comparing a leaf blower to an air nozzle with 100 psi. They put out about the same amount of cfm but the leaf blower could never spool up a turbo like an air nozzle could. Look up how steam turbines are built, specifically the nozzles. Keep it up.
