Don’t make the intake pipe go straight into the barrel, make it semi tangent so the air inside can swirl and burn better
Into the bottom!!!
Great idea sort of like how a centrifugal air or oil filter works.
@@ThePower1037 more wood flakes will get in the turbo
just dont have it knock up to much debris or the turbine wheel probably will get mangled, seen a few of these on youtube lately where air goes in the bottom and turbos getting chewed up
Route the intake air through a pipe or tubing internal to the burn barrel with holes facing towards the center. It acts as a diffuser as well as directing the flame front inwards. With the incoming air being routed near the walls of the burn barrel, it'll also act to keep the outer vessel cooled to some minor extent. If the fuel is semi-enclosed in a metal box within the burn chamber, less debris kicked up - the thing should be able to run on what amounts to wood gas.
it's time for fuel injection.
Okay this isn't a terrible idea
Was about to comment this. Or maybe even diesel injection or both haha
Fuel injection will turn this thing to a jet engine, whole point is to use wood as fuel, if you start using liquid fuel, that is not as interesting as it is now.
A little gasoline and nitrous would make this thing interesting
After burner??
This is what happens when video production quality meets mad lads. And I am here for it.
me too
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
?? Blow of valve works on the 'cold' side.
@@TheAdatto yes it does. Most jet powered airplanes and helicopters use cold side compressed air to power other things. You can pipe it in locations that would be affected by heat, and less temperature change won’t stress parts as much. I figure in this case, it might spin slow enough to not become a chicken flinging turbine
jet-shaft powered car/cart first for me seeing solid wood powering a jet, im use to liquid power or powder dust
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!
Great idea!
An intercooler would fix that issue
@@Jamxknife how would that solve the issue
@@PredaFran It stops shit from going into the motor
@@Jamxknife so they should get something that would immediately clog and fail, that isn't designed for this application at all, will cool down the air, which would make it lose power.
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!
Haha just need to convince someone to let us do it haha
@@MattBerrymotorsport :D
The thing about APUs is they compress cool air rather than hot, this barrel may or may not even damage engine components lol
@@poloska9471 lol
or since it still has useable exhaust pressure they just pop another turbo on the end and use that charged air to start whatever with @@poloska9471
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.
in the industry this is an afterburner and your idea should be implemented!
@@yz250ftony In the industry, it is also 'reheat'... They're the same thing, different terminology.
I think it is an American vs European thing. Kind of like "hood" and "bonnet" are the same thing on a car.
@@sstroh08 nah american vs biritsh. its like saying erupeans drive on the left
It may well be that there is unburned CO in the exhaust (similar to wood gas stoves), so even just piping the wastegate into the turbine intake or exhaust may get some additional power
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
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 🤔
Only one way to find out !
need an elite series haltech for electronic gate lads
Episode 5 coming soon…
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.
Electronic throttle bodies aren't stepper motors though, so the control is more complicated but would be awesome!
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!!!
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
Yeah, but the output gas is so hot it may break the wastegate.
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 th-cam.com/video/WTze6g9ZuF4/w-d-xo.html
Follow us on Instagram here instagram.com/eviltwinep91/
We love you and we'll always be there to give you stupid or even smart ideas !
btw, the wastegate is usually after the engine, but before the exhaust side of the turbo. you have it before the engine.
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
Could just do water injection like a jet skis exhaust
@@fattnnvxbhjnccnvvcyn if you do the copper tubing you can have a burn barrel and a hot tub
You mean like maple sap 😜💨
This would be counter productive if you do not install some kind of insulation on the inside, the purpose of the fuel is to get things hot, so don't smuther the flames.
nitrometh + water injection XD
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.
The mental image of them going "shit shit shit" as they back away with the whole contraption following them around is golden😂
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.
I feel y'all are edging up to that darwin award list. But by all means, soldier on 👏 👍. Great content
You know we live in Darwin, doesn’t that say enough lol
@@MattBerrymotorsport 🤣🤣🤣
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.
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.
Imho the tank gets to much air, so most of gases burn in it and that why it is getting so hot.
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.
@@Chozey-wq1bb repositioning waste gate won't fix the problems I've identified
@@Chozey-wq1bb yeah
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.
???
* If you want to do something similar to true rocket engines, you would have 2 barrels like these, but one is burning incredibly rich while the other is very lean, the exhaust for both of those would mix in the main combustion chamber -> rocket nozzle like you see in conventional rockets.
@@brycekovalik2381 would be interesting to balance the turbos for the mixture and egt. If one barrel was used to produce wood gas from another barrel of wood that would be very cool!
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.
You are taking it so far with all the additions. Fantastic and hilarious 👍👍
It’s not our fault, it’s you guys!!!
Its going to. Be a engine soon
@@ras4782 i was thinking this too! that you need a jet turbine on the exhaust, which can then be connected to a drive system!
Drilling that hole @1:00 is the most Territorian thing I have seen on the internet.
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
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
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.
Maybe active cooling the barrel? (Some kind of fan pointing at the hottest part so it can run harder for longer)
put it in a bathtub lid and turbo over the water line then pipe out rad then into the same car engine as the oil and use its water pump then back to the bathtub
Electric water pump with closed loop temperature control to maintain the exact temp of the barrel and cool the turbo.
A burn barrel hooked to a laptop computer! FN AWESOME
I honestly didn't think nitrous would add much in that setup, pretty cool lol
it would if you did a mild wet shot after the turbo, it would act as a afterburner but i would prob use something like heating oil its cheaper
Dude if you've ever played with nitrous you'd know it always makes HUGE difference.
@@thedude7726 Every other turbo burn barrel I've seen was not in any way starving for air - it looks like something was bleeding off boost way too early here and the nitrous was compensating for the flaw.
In fact before all the changes they were hitting 30 PSI and getting a runaway system - This seemed to go a bit too far in the opposite direction and was having trouble hitting even 5 PSI.
@@thedude7726 Not with a gas turbine , just a waste , nitros makes oxygen , a gas turbine dumps 3/4 of the oxygen coming from the compressor, straight out the exhaust, nitros is OK on an IC piston engine where all the oxygen is burnt , but not on a GT .
@@Entropy512 had a waste gate on it with a spring this was just a trial run
use petrol for fuel or spray starter fluid in the intake
i fucking love it. this is the greatest thing ive seen all week
"Danger to manifold!" @7:10 LMAO!
OutSTANDING work! Never knew these things existed, so guess what is tacked on to the retirement project list 👍.
Cheers from N.Z
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 ;)
It's gonna be a cold winter, glad you guys are keeping at this project I'm taking lots of notes from this 🤘
What a madlad's, love your crazy setup you guys have there!
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
Put an intercooler in front of the intake with a shroud to direct air like a car cooling fan
I like the idea of using the intake flow to move air across an intercooler, but question whether it would have any effect on the intake temp. You’d be rejecting heat from the intake air into the intake air like a thermodynamic ouroboros.
@@fjord-fjesta good point! It pretty much cancels the benefit lol I guess then use a electric radiator fan then!
Awesome build. Yes more improvements are needed.
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.
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?
We were very surprised too !!
N2O doesn't burn alone, you have to add fuel. Open a bottle N2O a bit and hold a lighter at it. Doesn't burn. You should inject it in front of the turbo compressor inlet to cool down the intake air.
Most of the air in a turbine engine goes straight through and is not used in the combustion - so most of the nitrous will also be wasted.
This is why the wideband sensor didn't show an AFR.
In a piston engine, a lot of the combustion heat is lost during the expansion in the power stroke, but if you run the same air fuel ratio in a turbine, the temperature will be way too high.
For the same power output, a turbo used as a turbine engine needs to be much larger than it would be when used on a piston engine.
You guys are feeling really brave w/ that car that close…….
Its a a good car!
Good work as always guys
Man, this is the best thing ive seen so far
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
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 TH-cam collab with Hunter Goodrich for this??? Earned my subscribe...cant wait to see where this goes!!
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.
Always make sure to keep the working material cool. Glad you guys know your stuff. Nothing worse than a hot foot.
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
th-cam.com/video/ujvFu_6DVG0/w-d-xo.html&si=EnSIkaIECMiOmarE
Pls give me turbo😢
Two things,
Don’t run a wastegate, run a blow off from the cold pressure turbo out , to, hot exhaust into turbo.
This will cool the exhaust and slow it but maintain full efficiency.
2, have you thought of running total loss oiling and feed the return into the turbo as fuel or even just as flame thrower?
3, catalytic converter as combustion chamber for diesel or oil feed.
Have you thought of adding propane injection instead of nitrous???
why not add oxygen wile there at it
The flying embers are hilarious! All the pressure pushing them through every gap
You should change the angle at which the compressed air enters the barrel to get a swirl on it for better burning
This is one of the coolest things I've ever seen
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.
Once you start making enough boost, you could use this as a booster for a small pickup truck.
It only makes boost because it's delivering boost to the fire. So impossible to use it for something else.
Sweet as boys can't wait for the next one
This will be the project that brings humanity together. Keep it up boiz we're counting on you.
Absolutely smashed it 😎 about to hit 14K subs ! The toe cooling system and kebab management 🤣
Hopefully next week bro! Hope you’re going alright
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
My thought is bringing the air up through the fuel like a lot of forced air furnaces do. Could be as simple as turning the barrel up on its end.
Then have some of the charge air bypass the fuel section to cool the exhaust and provide oxygen to burn the smoke/ash before it hits the turbine. They could put a throttle on the bypass pipe and use that for pressure regulation instead of the waste gate system.
My idea aims to have the fuel creat the heat and reach full combustion by the time it reaches the inlet of the turbine it may even make sense to feed stock in at the air inlet and direct the burn in only a spiral between the barrels. Also if you insulate the outside of your barrel you'll gain efficiency as well
Maybe make a pellet feed for pellets you would normally use in a smoker. I bet those would burn evenly and won't throw so many chunks.
Have a starter burn area open to the main burn chamber, and a larger metal box enclosure with holes or vents that the rest of the wood fuel goes into. The result is a solid fuel gas generator as long as it's kept hot enough (easy when internal to the burn chamber itself), it should run just fine as a wood gas setup and you can prevent debris from flying around if you're clever about it.
Keep doing video like this and in couple year your channel gonna be a huge success
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!
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.
I like this idea! Like a revolving door with little logs in each segment to keep it sealed. A fuel carousel!
Making a piggyback steam engine with the waste heat off the barrel would be hilarious.
@@matthewridgeway9250 yeah could build it like a revolver or something similar to that.
Could do this easily with wood pellets.
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.
Now THIS is how you make a turbo barrel. Fucken mint.
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
You need to use the nitrous to spool the turbo. Your just cooling the mixture down spraying into the charge pipe
This is awesome.
I could watch stuff like this all day. Haha. Nice.
Definitely need a baffle before the exhaust into turbo to keep churned wood from getting pumped through
🤣 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!
This might be the best thing I've ever seen
Believe me it’s only getting better
Seems like the ultimate in Turbo-Lag!
Thanks!
Thanks a lot mate much appreciated!!
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!
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.
LOL, I hope you're talking degrees F not degrees C , at 1000 C there'll be bits of turbine wheel flying out the exhaust
4:57 The magic moving wrench.
"add wheels and a seat next" lmao this'll be a new subgenre of land speed cars soon
WATER INJECTION. The water converts to steam, Expands to help boost, but also aids with cooling and prolonging the burn.
Coolbeens. Use the nos to spin the turbo at the wheel
the foot vice got me. 🤣🤣😂😂👍👍
love it lads. 😀
I lost it as soon as I seen you cooling the bare foot down with water XD
You guys are my kind of crazy. 👏👏👏👏
Welcome
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
Imagine sticking this to a car or pickup, connect it to another turbo that feeds the engine of the vehicle. Mad boost, sick launches.
I'm so glad I subscribed, also glad y'all actually put nos on it
Lol that foot coolant really got me.
I have been watching this,and a couple others like it... All in anticipation of success so that I have a running design to work with to make a multipurpose device that will heat my shop and be a great source for burning my garbage... Keep at it guys, couple more small problems to address and I think I will have what I need to fabricate something up.
i straight lol'd at the water hose on his foot!
Well done.
You listened to my EGT probe suggestion! I'm surprised they weren't higher. Cheers from Indianapolis
Twin turbskies fellas,
I'm curious what the barrel pressure is too... 🤨
Keep up the fine work lads 🫡
This has got to be the most refined turbo burn barrel I've seen on the internet.
Now it need a fmic, long intake pipe and a cable throttle body 🤙🏻
I never thought I would see someone datalog a burn barrel, but here we are!
9:01 beautiful!!
