Alright 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

it's time for fuel injection.

Don’t make the intake pipe go straight into the barrel, make it semi tangent so the air inside can swirl and burn better

This is what happens when video production quality meets mad lads. And I am here for it.

Please use the dump air from the blue off valve to power a rotisserie to evenly cook a chicken with the exhaust heat. Extra points for adding spices, peppers and onions inside the barrel to inject them at high velocity. Also, I’ve never seen a water cooled work foot before, I’ll have to try that

From other boost barrels, it seems that hot wood chip ingestion is a major issue. So a filter of some sort on the hot end (a simple cycloidal, perhaps?) is probably a good idea. Other than that, I think just upping the limit on the waste gate and you're there. This may be the most reliable setup I've seen so far!

You people are our type of people. We love stupid ideas!!! Let’s get this thing ripping 40psi next video!!! If you missed the second episode click here kzfaq.info/get/bejne/jbqqmJmYnsDZdmg.html Follow us on Instagram here instagram.com/eviltwinep91/

Put some fire bricks on the bottom so you dont burn out the drum at high temps. Maybe put the intake into the drum more to the side to cause a better vortex in the front part of the drum to distribute the heat in the drum more efficiently. And maybe try a copper gasket around the wood chamber opening since it seems to be leaking a lot of boost.

I still want to see you guys use your turbo burn barrel as an APU to start a very large engine!

Definitely much tamer this time. As a dumb idea, what if you added a 'reheat' feature? Pump a bit of fuel into the exhaust for an actual flamethrower. You *may* need a simple constriction to make that work, and a flame tube.

need an elite series haltech for electronic gate lads

Love the additions and using a haltech is just awsomly bonkers but I can't help but think once the burn barrel is perfected with ecu and potentially waste oil injection as fuel.... it could be the first step towards turbo steam power obviously that would jump the dangerous level up a bit but an interesting concept I think 🤔

Welcome to episode 23, here’s our fully forged block for the new compound turbo burn barrel. Our new anchor system is installed after the burn barrel pushed the shed from the back yard to the front last episode

Add a cooling jacket to the barrel. It'll last much longer. Use copper tubing and flow water through at a speed of 25 to 50 m/s

Real nice adjustments made! One thing what did catch my eye. A wastegate is supposed to bypass exhaust smoke, not intake air. This way it can still overspeed

So, I didn't mention this in my last comment, but for version 4 you should do an electronic throttle body controlled by a potentiometer. The stepper motor in those will allow you to open it consistently to precise amounts, this way you can have an idle, a low, a mid, or whatever you want and all you have to do is turn a clicky knob to the next position. Also a proper oil pump mechanism and an oil reservoir and cooler with a fan or two.

Love the overkill attitude of this. Id be curious how the wastgate would work on the hot side before the turbo like a typical turbo setup on an engine. Keep it up!!!

I feel y'all are edging up to that darwin award list. But by all means, soldier on 👏 👍. Great content

You can tell these guys thought every steps through. The part where they set the metal wrench on top of the hot burning metal thing. And the part where they connected the pressurized fire thing to their car were great. I was waiting for something to go wrong and they decide to try and back the car away from the fire. Either the fire will still be attached to the car and chasing them around, or they'll cut the oil lines and be squirting that oil into the fire. Its like watching a pack wile-e coyotes all teaming up to catch that road runner.

You are taking it so far with all the additions. Fantastic and hilarious 👍👍

The wastegate is just acting as a second blow off Valve, it's on the cold side of the throttle blade, it should be on the other side so I can still vent pressure from the burn chamber when the throttle body is closed.

Used oil injection for the fuel. If it's thick, preheat it using the exhaust. Great way to clear all the mozzie outta darwins rural area and get rid of old oil.

You put the wastegate in the wrong spot. It should be on the turbine side so you can dump pressure into the turbine housing and slow the turbine.

Couple of ideas. 1 - open the barrel and weld in some sort of mesh over the exhaust port of the barrel. Make it cover a large area so there's still loads of space for air to pass. Don't just put it in the pipe itself. The reason is because I could see in the video where chunks of fuel were running through the exhaust wheel and getting chewed up by the turbo. 2 - reposition the intake to barrel pipe to either the front and bottom of the tank facing the back OR in a position to encourage a vortex in the tank which will get oxygen to more places and encourage burn.

Read about Ericsson cycle, if you heat up compressed air with hot exhaust before injecting it to barrel, it should gain a lot of power and efficiency. Currently it works in Bryton cycle, which is best for multistage high pressure ratio systems - Ericsson is much better for low pressure ratio, like turbocharger gives. Also add some ceramic bricks inside as obstacle for direct path of hot gases to turbine side, should help decrease smoke production and prevent charcol chunks from hitting turbine.

You should make a rocket engine next. Get 2 turbos and make a turbo pump, one for fuel on for air. Mix it in a nozzle and voila, home made rocket engine.

i fucking love it. this is the greatest thing ive seen all week

Drilling that hole @1:00 is the most Territorian thing I have seen on the internet.

Awesome stuff boys I'm obsessed with these videos and wanna build one. I reckon add a hectic intercooler and a throttle body after it just like a car so you can build boost and shut it for some mad turbo dose/flutter with all that added volume of the intercooler

A burn barrel hooked to a laptop computer! FN AWESOME

My suggestions would be to line the lower third of the barrel where the fuel sits with fire brick and have water injection on the inlet of the exhaust turbo.

if you go to 9:25 and press "L" and then "J" to skip back and forward whilst the video is paused you can see how the canister deforms in the heat

Maybe active cooling the barrel? (Some kind of fan pointing at the hottest part so it can run harder for longer)

The car being used as an oil pump like an old-timey blood transfusion got a good laugh out of me! My thoughts for further development would be a throttle-controlled bypass tube that lets some of the charge air past the barrel, that way boost pressure could be controlled by letting some of the air skip the combustion chamber plus the cold air mixing in could cool the exhaust and burn some of the smoke before it hits the turbine. Maybe something to distribute the air coming into the barrel too, looks like it's heating the hell out of the spot right below it. Also maybe a slight jet-like nozzle for the post-turbine exhaust to see if it can get some thrust going ;)

"Danger to manifold!" @7:10 LMAO!

Two fuel injectors, using diesel because it's a lil more stable at temperature. Put one where boost enters the tank and one on the turbo outlet. Run it with a micro squirt ecu. You could also pipe the boost further into the tank with some kind of diffuser tube to help prevent hot spots in the tank and a potential blow out.

Hey guys episode 5 is out now and is by far the best episode yet!! (Electronic wastegate and we build a flamethrower) click the link here and check it out kzfaq.info/get/bejne/q9CmediQm6q6d2Q.html&si=EnSIkaIECMiOmarE

I honestly didn't think nitrous would add much in that setup, pretty cool lol

A jet engine(or the power unit of a turbofan) will often have ~80% bypass air, that is only 20% of the air sees combustion, and 80% cools that air to safe levels for the metal of the turbine and housing. As for the turbo barrel, adding a 1/2 or 3/4 pipe with a ball valve to dump air from the intake tube (before the nox), into the barrel to cool the exhaust heading into the turbo, could be used to prolong the turbo's life, unless it causes a secondary burn, in witch case its gonna shoot fire directly into the turbine. That said you should probably have a baffle or 2 before the barrel's exit to the turbo, to extend the minimal distance the air/flame will travel from the fuel to the turbine.

Now THIS is how you make a turbo barrel. Fucken mint.

OutSTANDING work! Never knew these things existed, so guess what is tacked on to the retirement project list 👍. Cheers from N.Z

Seeing how many times the bottom has heated up, you should add a second layer or more support so it doesn't burst out the bottom

You guys are feeling really brave w/ that car that close…….

use petrol for fuel or spray starter fluid in the intake

damn. i read online that jet engines(even wood burning ones) cant run nitrous properly. i was wrong. as soon as i saw that nitrous i was like what the hell? that actually works?

Those weld’s are better than the weld’s on my turbo manifolds! Not even kidding! Btw It sounds lean af that’s why the nitrous didn’t go ballistic she needed a wet shot but leave out the fuel jet for max fuel or run kero

It's gonna be a cold winter, glad you guys are keeping at this project I'm taking lots of notes from this 🤘

The flying embers are hilarious! All the pressure pushing them through every gap

The data logging is neat even if overkill. But now you have some stuff to go on if chasing an "ideal" design. The temp difference across the turbo shows how much work it's doing. The main things with this one is there's no run-away condition with steady RPM on the turbine and the oil situation was good. In that regard it's a success. The visible issue is the hot-spot on the burn barrel. Maybe try having the incoming air come in through a coil of high-temp tubing that spirals around just inside the burn barrel with air-holes facing inward? Although having the fuel fill panel on the side rather than as an end cap means you might have to do something besides having the incoming air tube spiral it around in that area.

Put an intercooler in front of the intake with a shroud to direct air like a car cooling fan

Imagine sticking this to a car or pickup, connect it to another turbo that feeds the engine of the vehicle. Mad boost, sick launches.

This is one of the coolest things I've ever seen

Have you thought of adding propane injection instead of nitrous???

I think a bigger tank with a built internal setup to create swirl inside the barrel will produce higher boost pressures as well as reduce the spot thermal stresses that might prevent higher boost pressures. Maybe a cool KZfaq collab with Hunter Goodrich for this??? Earned my subscribe...cant wait to see where this goes!!

You guys are fucking mad lads i love this. This is the type of shit i wish my dad was still around to watch with me. Cheers boys!

You should change the angle at which the compressed air enters the barrel to get a swirl on it for better burning

Definitely need a baffle before the exhaust into turbo to keep churned wood from getting pumped through

Absolutely smashed it 😎 about to hit 14K subs ! The toe cooling system and kebab management 🤣

Once you start making enough boost, you could use this as a booster for a small pickup truck.

What a madlad's, love your crazy setup you guys have there!

I never thought I would see someone datalog a burn barrel, but here we are!

The largest improvement would come from having a way to meter the fuel burn exposure the hotter and more evenly you heat the fuel charge the more stable the performance. I suggest a internal burn chamber that mixes the fuel in a quantitative manner. Maybe a barrel inside that you can slowly add into the outer barrel. That will reduce the turbo eating large chunks of fuel

4:57 The magic moving wrench.

This will be the project that brings humanity together. Keep it up boiz we're counting on you.

Make it like a feeder nuclear reactor. Have some chamber that can regulated the flow of wood into the main chamber. Could use piston like device that could drop down a perpendicular cylinder to the main chamber. This would collect more wood then bring it up to add more fuel to the main chamber. This would allow for modulation of fuel material while still keeping the main chamber pressurized. This would allow you to modulate the temperature. Also you could water cooling to the exterior and capture that thermal energy.

You could try do direct the fresh air from the blow off vent into the exaust pipe behind the turbo. Then ad some diesel and it should act as an afterburner.

Seems like the ultimate in Turbo-Lag!

"add wheels and a seat next" lmao this'll be a new subgenre of land speed cars soon

You need to use the nitrous to spool the turbo. Your just cooling the mixture down spraying into the charge pipe

This is literally how a turbojet engine works. Ooohhh, i see now, you misspelled “The most advanced/dangerous wood fired turbojet engine on the internet”. Sweet! This project is seriously awesome. How does this not have millions of views by now?

Awesome build. Yes more improvements are needed.

Always make sure to keep the working material cool. Glad you guys know your stuff. Nothing worse than a hot foot.

Twin turbskies fellas, I'm curious what the barrel pressure is too... 🤨 Keep up the fine work lads 🫡

I lost it as soon as I seen you cooling the bare foot down with water XD

WATER INJECTION. The water converts to steam, Expands to help boost, but also aids with cooling and prolonging the burn.

🤣 just wanted to say man I fkn love these videos. Nothing like a turbo screaming along. There’s not many on the internet so if you keep making these you’re looking at a gold mine. Keep it up man!

Have the intake pipe go along the outer circle and slightly pointed towards exhaust so the barrel heats even and all the coals get air across them.

Now it need a fmic, long intake pipe and a cable throttle body 🤙🏻

Keep doing video like this and in couple year your channel gonna be a huge success

Good work as always guys

Man, this is the best thing ive seen so far

Look up wastegate crack pressure. A 1 bar spring is 100% open at 1 bar. It cracks opens significantly lower than that. Your sensors are correct. The reason it didn’t maintain boost is because the fire never got hot enough to maintain “turbine drive pressure”. Give it a bit more fuel and a bit stiffer wastegate spring. 1000-1300 egt is considered “safe”. steel starts to soften around 1300 degrees sustained.

This is NASA levels of fucking around

The most hi tech fully hectic burn barrel in history! Let her rip!!

Can you please partially pivot to a cooking channel and weld a basket holder to the end of the pipe so you can healthily airfry chips and wings 👌 Later you can add a compartment and use as a turbo woodfire pizza oven

When it's fun, and in it's own way, a learning experience it's just that much better. It's also fun to see things spin at high rpm, and burn quickly

Thanks!

Coolbeens. Use the nos to spin the turbo at the wheel

Sweet as boys can't wait for the next one

Using the car as an oil pump felt like a dad joke.

Now this is just great stuff right here!!! I can't wait to see where this little project goes lol id call it a turbo reliability test more than anything hahaha that baby was cherry red and she's still spooling!

My man’s just making a fighter jet in his backyard

I could watch stuff like this all day. Haha. Nice.

This is awesome.

I'm so glad I subscribed, also glad y'all actually put nos on it

It needs a intercooler for filtering and cooling BUT Methanol injection is the shit you need to send it to stratosphere.

This might be the best thing I've ever seen

literally pissed my pants laughing when I saw the hose go on the foot. I'm thinking, fark you're game using power tools barefoot, then the hose came out = mission accomplished!!!

1:54 The 20B just chillin under the workbench 👀

NASA JPL sends a man into space on a rocket. Two Aussies with an air compressor barrel and a turbocharger... Hold my beer
