J: "immagine what a full size pulse jet engine can do" Colin furze: "hold my safety tie"

The ideal engine for the backyard. All neighbours will love you !! 😂😅 I've tried it once or twice. Great effect !

The loudest and highest velocity fart ever measured.

Brings me back to the days of pulse jet engines on colinfurze's channel

Back in the '80s I worked at a company that made model pulse jets, Curtis Dyna Products. They called them Dyna Jets. They were indeed *loud*. Hearing protection was a must. A university bought some of them from us to use as experimental sound sources in their experiments to sonically sterlize soil. I never heard how those experiments worked out.

"simple base" pulls out a whole lab equipment rack xD

When I saw the title the first thing I thought was "poor neighbours". Good that you realised they are extremly loud on a beach!

One minute in and the p*** bots are here already, youtube still has not found a solution apparently. Love your videos mate!

Johnny's dabbling in some ADVANCED tech now!

IM PUMPED! Definitely wanna see this power a long board with you on it!!

Scale model of V1 when?

Bluddy marvellous. Way to go sir!

3:53 to 3:58 The same sound that my father makes when he gets up in the early morning to go to the bathroom.

Looking forward to you installing it on the RC 4wd

Wow!! And here I always thought these things ran a little hot. lol. Nice job!! : )

That was MASSIVELY COOL!!! 😊

Very cool! Thanks for sharing

We have lit a full scale of the eng that was used on the old buzz bomb used in the war back in the day, it will make your insides move in ways they never have and multiple layers of hearing protection is needed

These things would make great tornado sirens 😅

Крутой дядька, Михаилу мои слова благодарности и прибавка к карме за такого гостя!

Was buzzing so loud it knocked things off of my shelf, I feel you Johnny haaha

Pretty freakin cool bro!

Robert Maddox would be proud of you

The heat! I thought the was going to start melting!

I run mine on LPG. its a bit bigger and made from stainless steel, but has no reed valves to worry about. the supports are unable to stop the thrust from moving it, so I need to sit a few bricks on it, but yours is amazing, esp the cherry red heat.

HA! We had one of these in auto shop in high school. Finally convinced the teacher to run it one day. Made so much noise, the principal came down to see what was going on. The auto shop was about the furthest classroom from his office.

Cool as heck, think a good addition would be a venturi at the tailpipe connected to a sheath to get some airflow over that chamber. For static use, anyway.

Can't wait to see a R/C V1.5 flying around

Και πάλι Μπράβο

During WWII, the Nazis launched flying bombs, powered by pulsejet engines.....they were known as "Buzz Bombs".

It's way more fuel efficient than I expected. Given the amount of fuel you added to the tank, I was thinking it was too little. It barely moved as far as I could see.

Way Cool Johnny 👍🏻

That was awesome...

Best marshmallow cooler EVER!😂

Wicked. Which part of Aus did you blast out ear drums? Nice looking bay

Nice. You should try making the rotating pulse engine next!

Cool! That thing is freaking loud indeed 😂 but what was the thrust reading? You built a nice test rig but I'm curious for the results!

That. Is. Awesome.

Cool. What's the thrust???

That looks exactly like a Mercury outboard boat motor Reed valve. The Reed valves on these motors are on the crankshaft journals.

It’s amazing how fast it got red hot😮

This is awesome. What kind of thrust did it produce?

15y ago i build few super small ones , smallest one used 7.62 shell second one was 12g co2 bottle from asg (both needed sustained rly small amount of airflow to work- i used for that air pump from blood pressure monitor) ---- they were so loud that neighbours were annoyed when i turned them on

That started well. I've seen others that were a pig to get going 👍

Made a valveless PJ out of titanium a few years back. It's about 38" long with a 6" combustion chamber. I use propane to fuel it. Much easier to start and with valveless PJs you throttle them way back. Anyway, I start it with a Campbell Hausfeld 20 gallon direct drive air compressor. You know, the REALLY loud obnoxious ones. At full throttle, the PJ is so loud it completely swamps out the air compressor, to the point where you can't even tell it's running. I can feel my chest cavity resonate with the jet. Yeah... They're loud.

3:38 the cameraman was shocked

The way the camera person *jumped* when it started! Those things are crazy loud though

That would make a crazy siren.

I Love This ❤️❤️❤️❤️❤️

amazing that it doesn't melt the stainless, but I suppose that if its flying then the air rush would cool the pipe

I need one of these as a home security alarm.

I think that one even scared the fish 😂

Hello What about trust meter? You forgot

ah yes the propulsive whoopie cushion

It looks super hot 🔥 .... did you put a heat gun on it to see the temperature of it ?

Where do you buy your Aluminum Extrusion and Fastners ?

Looks like my old dad's motorbike exhaust 😂 👍

You might want to add a cross brace on your uprights. At that height your current stand might make the bearings less efficient and the readings could be well off.

More jet enjine videos!

Could you try running it on HydroDiesel. I think that would work and have been wanting to see someone with a pulse jet try that fuel. It may run considerably cooler with about the same amount of thrust.

Yes, yes they are loud. Are you ready to graduate to turbocharged burn barrels next?

Is this HOA compliant? No? Where do I order it?

I need one of these for the back yard, fire it up whenever all my neighbors are making too much noise lawn mowing and weed whipping!

Challenge for Johnny: making a mini turbofan with AFTERBURNER😊

They made an even greater noise when the warhead they were attached to during WWII exploded in London !

Well, I think the 1:1 scale ones are louder but on a lower frequency so they hurt a little bit less - but you are feel them more in the stomach...

Great spot to run a pulse jet . What are we thinking, mate, a dragster or maybe a speed boat to go over to the island in this video, so where is this just a great backdrop.

nice, sounds like a 2-stroke engine at full rpm, like 20k or 200k rpm.

Question : is that speed stable ? can you increase the speed ?

The sound is almost like a Formula 1 V10 engine. 👍👍👍

That thing has now deafened Poseidon, what a noise!

👌🔥

So how much thrust did it achieve??

How do you determine the pulse rate?

Is the thrust tube stainless? When you look on their website, they say the "material" is Aluminum. I assuming they mean the valve body?

Lovely kit. Any idea how long one valve lasts?

RC airplane incoming!

what are you going to do with it? is it just a demonstration model or are you going to make a pulsejet rc plane

Now you should make an R/C model of a V 1 buzz bomb to put it to use!!

Greetings from Germany.

the older generations with PTSD from the V1s...

EHH, WHAT? DID YOU SAY SOMETHING?

4:00 that one moscito when try to fall asleep

5:10 you can hear the heated parts cooling and contracting

Integza would be proud

This one runs on gas, but these things can run on anything as long as it's flammable, including solid fuel. It is perfectly doable to have a pulse jet that runs on coal dust, or even wheat flour.

You showed us a force measuring gadget. So what was the thrust created by this pipe bomb?

So how much did you measure the thrust with that scale?

yes johnny q 90, that was a reed valve engine, a proper pulse jet is 3 times as loud.

👍👍👍

imagine putting flute holes in it and using some solenoids to cover the holes loudest instrument ever

I would absolutely love to see that thing in a plane

do a boat! we want a speed boat! what was the thrust? when are you and toyan doing some Motor giveaways contest?

This is my last time asking you to make a model inline diesel engine 😭

can you build a RC plane with this engine? With fpv drone parts

Well, how much thrust did it make?

Build a V1 Rocket with this

How much power did it produce?

Who else is waiting for Johnny to review the new Cison V8?
