Episode 6 is now out, we put it on the roof of a car and drove around! Click the link here and check it out! kzfaq.info/get/bejne/rKmPlL2Fx52UpWQ.html

The best part about making something dangerous is when everyone starts running away laughing nervously 😂

Love that the main takeaway from this was "we need a bigger boost gauge"

Their tool safety is incredible. Those safety flip-flops are the bomb!

"We need a bigger boost gauge." Is 100% the attitude we all need! Brilliant!

These turbo-burns are fun to watch, and I'd love to see it taken to the next level of backyard engineering. For example, partially submerge the tank or weld on some tubes to the tank and pump water through. Use the heated water to rapidly heat a swimming pool. Or use the exhaust gasses to fill a hot air balloon. Or go more of a technical route and do some analysis on the exhaust gas composition. Or build a mechanical PID closed loop system using a BOV / wastegate, and throttle body to get the system to maintain a steady boost that you can select. Or put it on wheels, add basic steering with an RC car servo and get the thing driving under its own power. Or add an oil cooler and pipe the intake to draw air through the cooler so that the system is able to maintain better oil temps Or... you know, the grand finale, add a 100 shot of Nitrous

That’s wild. At 30psi it is like a supercharged forge. Get some EGT gauge happening for the turbo and inside the furnace. Be cool to know how hot the fire gets.

Watching the guys run for cover reminded me of the Ford Dorset engines. I started my 40 years at Ford UK Product Development at Dunton in Environmental Test where we did cold start tests in four big cold rooms that would go down to -40° (-40° is the crossover point for fahrenheit and centigrade). Between tests the engines, which were on pallets so we could eight in each cold room, were run up for at least an hour to evaporate any fuel that had got into the oil while cranking. The oil was changed between every test as well. The Dorset engines could get so hot that they would start to run on oil vapour that was piped to the inlet manifold from the engine breather. With nothing to control engine speed they would run away and eventually explode! We had one brave lad who would run in and pull off the breather pipe, but most of us ran for cover. The runup room was lined with sound proofing and I can still see bits of crankcase embedded in the wall, and an almighty mess that we had to clean up. This was in the mid 70s so we didn't all have phones to record these events, and having a camera onsite was a sackable offence anyway.

Throttle should be setup to dump boost to the open air, not restrict that going to burner. Instead of hammering the thing with excessive backpressure, you drop the overall system pressure feedback to the burn chamber. Make a Y or T junction somewhere on the main boost line from the turbo, and stick the throttle on a branch from that to vent. This is because you're not able to control fuel in this setup, so instead you control the fresh air being introduced. If it's done right, it should be able to do some pretty smooth throttle control. Also that compressed air being vented will be rather hot too, so direct it accordingly. Also if you're clever, design internal burners to use the pressurized boost air. The flame front will form from the fresh air coming into the atmosphere of heated flammable gas. If you ask somebody who works on stuff like coal fired powerplant burners, they may be able to explain it better. Still room to optimize it if you want to. Or just ignore random internet person suggestions, yet the advice is out there.

Safety Flipflops like a Boss!

“3 pounds, 5 pounds!….*needle passes 25 PSI of boost*” and the the scream lmao 🤣

Now this is what I was looking for about 11 years ago, I had a wood furnace with an "electric supercharger" that regulated the input air to control heat output. Interesting thing, but I'm more of a turbo guy, but nobody had done that kind of swap yet. Good job guys, Turbo wood stove is a win in my book lol

You need to control drive pressure. Venting the vessel's internal pressure before the turbo exhaust. Choking the air charge side will destroy the turbo oil seals rapidly. You can gain more control by fabing up a spring-loaded vent cap on the charge pipe. Set the spring tension to be fully open at 1.5bar. Allowing the charge air to vent to the atmosphere at a regulated pressure. This will stop it from running away. If you turned it into a boiler with steady water flow circulating through it, you'll have stable temps and a pile of steam that could used to warm a house, a pool/tub or power a steam turbine genset.

Feed some fresh air directly from the compressor to the exhaust turbine to cool things down, and it should survive a bit longer. (That's how they do it in jet engines.)

That tiny bit of extra air making an extra 25+psi of boost is a great example of how turbos cars drive too, once you get the turbo rolling you can be giving very little throttle and still make a lot of power.

These are rooky numbers. When my dad sneezes, he produces at least 69+ psi of boost.

Wonder what it would do if you put coal instead of wood? 😂 Great fun though as is!

You need a better way to control it. A waste gate or dump valve something anything more then the throttle which was a decent idea but it unexpectedly failing like that didn't help. Was still funny though and great to see in day light. The only other thing you might consider getting is an oil cooler you almost had another type of fire there lol

I love seeing these builds, and have watched videos from Bobby McBoost, some guys out of portland, a few others. The one common thing I see is the boost becomes uncontrolled and the turbo blows up every time. It doesn't seem like limiting the intake air works. You need to limit the fuel. I'd like to see a build using wood pellets (Pellet stove) as the fuel source. By adjusting the speed of the feed auger you can increase or decrease the fuel intake rate.

Omg this was awesome exactly the type of videos I’m looking for please make more content about this you definitely earned a subscriber

Grab an axial power turbine from a Detroit diesel dd15 engine and add it after the turbo. You could rig up an alternator and now you’ve got yourself a generator powered by literally anything that will burn 👍 Of course you could use the gear from the power turbine to power a myriad of other things, but electrical power seemed the most desirable. Now to figure out an easier way to start it 👍 I also liked the idea that several others mentioned of using a wastegate to help keep the impeller cooler. If you added an EGT gauge you’d be able to dial it in for maximum sustainable power output, which again would allow you to use it as a generator. Another good idea may be trying to add a screen coming up to the turbo to help keep chunks of wood going into the turbine. Cool project 👍 keep it up

Good to see you’re using all the safety equipment

I love the tool use you guys left in, it makes it less discouraging for people who might want to do this at home!

Seems to have warmed up my living room just watching it, good job.

Needs a waste gate and a manual boost controller. You also need a blow off valve to let the boost pressure out when the throttle plate is closed.

Absolutely smashing the algorythm boys !!! Fantastic video, already got me wondering about the next episode 💪🏽😎

I love the health and safety aspect and precision engineering🤣, nice work!

That's the funniest thing all week so far. You guys are ridiculous haha

i have no idea whats happening besides a turbo doing its job but man is it insane

The level of safety in this video is AMAZING!

Build a fresh air cut off like the manual plate your using with a pull cable and spring to return to off. And yes bigger gauge. Your almost there!!!!!!

Probably the best turbo experiment i’ve ever seen! Just incredible!

Holy crap. I love everything about this.

I'd put a T on the boost side and have the throttle body act as a pressure relief instead of trying to block the boost. I think you will get better control over it by venting excess boost/air out of the system.

You should weld in a metal mesh before the exhaust side of the turbo to help preserve the turbo

I suggest use a thicker oil, like racing oil, and an oil cooler, just don’t forget to use an expansion chamber in case oil overheats

love it. i’ll keep up to date w this channel. all things

“We need a bigger boost gauge” haha yess

Throttling the compressor outlet without blow off valve puts it in surge and destroys bearings. I like the bypass air idea, compressor inlet emergency throttle, particle screen before turbine inlet, and waste gate. You should probably have some fail safe tank pressure relief before the tank pressure limit.

One of the coolest and outside the box projects I've ever seen!🎉😂

Just in case someone hasn't already said this - Keep a water hose handy, if it runs away turn the hose on and blast the turbo inlet. I imagine it will hurt some things, but it might be better than a complete meltdown.

perfect for that family camping trip

We just hit 10,000 subs! You idiots are no more responsible than us!!!

Thank you saved me a lot of time trying to browse videos for an actual working one

Now THAT is a high quality turbo!

Hi Guys , you're getting there, your P2 pressure is dependant on the TIT temperature going into the turbine stage , with our homemade DIY gas turbines using turbochargers we only need ~350-400 deg C for idling at 7 psi P2 , but ~550 C for higher powers , you need to be able to lower the temperature going into the turbine , the TIT , to prevent overspeed , so put your bypass/shutoff valve on a tee piece and feed the outflow from it to the duct going into the turbine scroll , once you hit your desired P2 slowly open the bypass to maintain it , the mix of hot gases and "cold" air will produce the require TIT , you will then be able to add a jet nozzle onto the turbine exhaust to produce thrust/noise, or add an afterburner for even more thrust and noise

I like when it pegs out and they take off running

Thx for sharing. This is completly NUTS🔥 INSANE😍❤️🔥

You guys running around frantic laughing brings back so many sketchy memories 😆

You need a high pressure relief valve on the compressor side with a water injection tank pressurized by the compressor and regulated by the size of the water injection nozzle. This setup will help control and stabilize the operation. You might also need a larger turbocharger unit.

I love these videos, it would be cool to see the system accomplish some sort of work.

I just found this channel now i wish you guys best of luck with your new youtube channel!

definitely earned a subscriber. once you guys get the control portion of it dialed you should experiment with different fuels, maybe dump some oil in there... lol

Would be cool to use diesel as the fuel source instead of wood. Certainly would save the turbo from being destroyed by debris. Also, perhaps a better coolant system is needed, that oil was about to flash for sure. Can't wait to see phase 3!

Holy Geezus, I'm 2 min in and curling my toes. The Aussie safety equipment and protocols are AMAZING!!

As more than a few have said, need to have most of the air bypassing the burn chamber and mixing with the burn chamber exhaust to limit the EGT. Put a Y pipe and 2 throttles on the compressor discharge, 1 throttle to the burn chamber the other to the bypass duct. Mechanically link them to be opposite each other, when one is open the other is shut. Like so your control rope can control the burn rate while also keeping the exhaust gas temp down. And having both throttles on the cold side will prevent that sudden failure, what got you was the hot gases damaging or jamming it. Also consider a much longer rope, or better some form of radio control that can shut this thing off from across the field. Its all fun and games till someone gets hurt. Even better if you can put a guillotine gate on the intake, run from a separate remote as a failsafe.

I would add a tube to the compressor inlet and put a throttle body on that tube. This is your emergency shut off. Then add a wastegate to the compressor outlet where your current throttle is. Make sure the wastegate is manual and will purge at a set PSI. I'd set the psi to 20. This is your automatic throttle. Then add some sort of baffles / screen to the turbine inlet to breakup or catch wood particles before they go through the turbo. Then get a better pump so make sure there's enough flow and add a bunch more oil since coolers are expensive finicky. It won't run continuously, but it'll keep the oil from burning.

Love the safety flops! May wanna go Crocks if you feel that you may need crush protection. ;)

Loving the safety flip-flops, and "grip anything" vice there lol...

Thank-you for your content.

Would be so cool to see this used as a water heater of some sort! This is such a fun project.

Gasification is a great fuel source it was used alot between 29 and 49

You blokes are legends. Crazy but legends.

Christ Berry, you guys are nuts!!! Love it!

You should force the exhaust through a cyclone separator to limit ash and debris going through the hot side of the turbo.

This is awesome! Any chance you could mount an actual wastegate before the turbo on the hot side? or would it just melt? hmmm wish I could play with fire too!

I watched a few of these and thought these guys are mad, then I saw the Territory plates and subscribed, as I lived there for 32 years.

I loved that video, for the moment there that engine is going to explode 🔥🔥🔥💕💕

It seems like this experiment is vastly scalable... I would like to see you guys experiment with some sort of high-octane liquid fuel being injected...

Needs a pyrometer... for science

The hole bit breaking halfway through is painfully relatable

Good to see you guys using the right ppe-thongs,no safety glasses, no hearing protection,no gloves. Very good.

When air is flowing past the throttle blades its more difficult for the blade to close.

put a plate in it with a bunch of 2.5x25.4mm slots in it, to stop the large wood chunks. put a propane line in the intake pipe, wrap a bunch of copper/steel pipe around it, get 20 foot of catalytic converters copper/steel pipe wound around those to and about a foot think of insulation with 3mm aluminum sheet cover... how much water can it boil up to 400psi off one BBQ tank? get about 1200ft of one inch tubing to run water thru... put an electric motor clutch on the turbo intake. burry the water tank in a 40 ton cement block... 400000 watt compact space heater 26000sqft at 8*C with it being -78*C outside... how long does one tank last?

This is actually such a cool idea. It would me amazing to see this thing actually do some kind of work. It makes me think of either a ram jet or a turbo prop airplane in the way it functions. Except that it runs on wood! Very cool

Best video of the year!

Putting an oil cooler in front of the intake side of the turbo and a wastegate would definitely help make a controlled sustainable burn

Maybe next time with an air to water intercooler?

Good to see the correct application of the safety jandal

Loving the health and safety flipflops.

I'd say get a boost limiter (and obviously a new turbo) set the boost and check the boost & RPM ratings of the turbo. Those things might be able to go a LOT harder than you think. Also you might wanna rig up an oil cooler with a much higher flow oil pump. Something like Superfastmatt has on his motorcycle powered car. You practically made what the aviation industry calls a "start cart" except way too cheap lol. But if it's safe, starting up a big jet engine on nothing but cheap firewood would be hella cool but nobody is insane enough for that lol

Absolutely hilarious when it started spitting wood 😂🤣❗️

that's one the crazyest thing i've ever seen. Science is just great, i'm lovin in

Omg that thing sounds like it's going to kill everything around it. Awesome 💪🏻💪🏻💪🏻💪🏻💪🏻

Can you run it with sugar?

Love those pro safety goggles when grinding🤣

It's good to know that you work with the safety flipflops on!

Put a throttle body on the compressor inlet.

Hi, i'm an aeronautic mechanic, and I really love your videos on that turbo-barrel ! I'm working on making one myself lol, anyway, here's some ideas: -Firstly (and most important advice in my opinion), add some kind of strainer / filter for that turbo, small unburnt wood particules are hitting the blades, and at that speed (i'd say approx. 40-50k RPM) , you're destroying your turbo. ( it would be nice to preserve that beautiful GT45 a bit more than 3 runs). -Your charge pipe being that long and straight, why not add a small intercooler (a bit like on a car) to give your turbo some good ol' fresh air ? -And last but not least, why not add a small radiator as an oil cooling system, (like a small motorcycle radiator or something), bc that oil is just vaporised into smoke, you gotta cool it or your turbo will seize and potentially injure one of you guys !

you guys should add a solids return tube with an expansion chamber before the turbo and add in a fine grate to act as a filter for larger solids to block them from entering the turbo. I'm not sure how much boost you'd lose if any but it is something to try.

Definitely needs a bigger boost gage..thanx for the share gents.🙏🏻

Episode 5 is out now and is by far the best one yet. Click the link here!! (Electronic wastegate and we build a flamethrower) kzfaq.info/get/bejne/q9CmediQm6q6d2Q.html&si=EnSIkaIECMiOmarE

You need better throttle control. An electronic throttle body hooked up to a gas pedal, in front of the turbo inlet.

Love that y’all are cutting metal and drilling it with flip flops on

WOW, gotta try this in the future. A refuelling system would be nice that swaps out waste, you got yourself an engine.

BTW WD40 is the worst lube for drilling/tapping. Get some real tapping fluid and you'll thank me. (Your drill bits will also thank me.) Oh yea, metal cable doesn't burn. String does. Come on guys... you gotta think a little a head.

Hillarious regulate the pressures and install in a pickup. Could be the worlds fastest wood/coal powered motor

Insane! I really appreciate your oil pump! A Drill!

Wow gnarly! Happy I found you guys

That turbo is having an aneurysm lol insane boost but the turbo charger seems to love those hot shots, truly a hungry turbo right there 😂
