Created on June 28, 2009 using FlipShare. Quick run up at the American Military Museum in El Monte, California. Siren run at under 1000RPM. www.tankland.com
Only "32 dB"? Um, no, Sparky Junior, you've got it screwed up. They sounded at a whopping *138 dB* at full power (measured at the standard 100 feet away)! They're the world's loudest sirens! But then still, they were made and used, which means it was okay at some point to rev them full-blast. And some of them also had a seat right on them for either revving them up and down manually while spinning around, or for engaging the clutch or something, so without remote-control mechanisms attached, someone had to be right there to operate one. They would have ear protection on, of course. So those,, then, revalidate my above question.
David Stall is fortunate enough to own one of the three fully functioning Chrysler Air Raid Sirens that exist today. He also has his siren located in rural Texas surrounded by lots of open space, which is very helpful since he loves to run the Hemi® and blow the siren. The clear zone (minimum safe distance) extends 320 feet. Even then, if you are in front of the siren it would be uncomfortable and prolonged exposure could damage your hearing.
for those wondering, this system was built in the cold war era, in case of a Russian or Japanese attack on american soil, so they wanted the most powerful siren to alert cities of the imminent attack in order to evacuate as earlier as possible, they wanted to mount the least possible, but the louder posible sirens at that time this system was mounted in a rotary base so it would be listened clearly as far as 16-25 miles at full throttle, that's why it had an industrial HEMI 331 V8, and the compressor system was a 3 stages system peaking at deafening 138 dB at 100 feet.
138dB at 100 feet is just absurdly loud. A rock concert where you would feel slightly uncomfortable from the volume would be at around 110-115dB just to put it into perspective. And the gap between 115 and 138dB is MUCH MUCH bigger than people may expect it to be.
What happened? I don't know how this thing works. But it didn't really start. From what it sounds like and I'm blind by the way so just guessing from sounds that truck engine thing after you warm the sucker you open up the siren how ever that works which they did but correct me if I'm wrong after you start the alarm part aren't you supposed to rev the Hemmy? To get the thing really going? Also at 138 DB SPL it's mind blowing to think that the little snap off mics of a Zoom H5 will handle this sucker. Also the Zoom H4N Pro. The H6 XY mics will almost cause they take 136.
@@MrHamit64 The siren itself is powered by the engine you are hearing. The engine is spinning a gear system, connected to a rotary disc which is perferated, and chopping air creating the pulsing pattern and producing the siren sound, firstly the engine is started, then the gear lever is pulled, allowing the drivetrain to interacted with he siren "chopper" assembly. The entire siren is about 12 ft long. The siren is directional so therefore when the engine is running, through an intricate pulley system, The siren rotates 360°. Hopefully that makes sense to you but it's a little hard to explain this to someone who's blind
@@seanjuth Ah kinda. But I guess my question was more on how you work the thing. So you are supposed to rev it then once you get the siran part going then. as to how it turns I'm not good at angles. So I'd hav to touch the thing to see. But I kinda get what you meant. But again my thing was more how do you get the thing going. So yeah I guess once the ciran was going they didn't really rev the engine to really make it go then.
We watched one being run up in Halfmoon Bay at the show at the airport. It actually lifted 3/4 inch gravel off the ground and made it dance like it was water on a hot skillet. Made your knees buckle darn near
@lexmarks567 There was a remote control box that would allow all the sirens in a given area to be triggered from a central location (usually the fire station), plus a "local remote" at the base of the pole or inside the building it was mounted on, so it could be triggered locally without going up to the actual siren. Obviously, there were also controls mounted on the siren itself, too, as a final option. Many of the control boxes would have been retrofitted for radio operation later.
0:46 seconds Reminds me of workplaces where the power tools are run on the same power grid as the discharge lamps and somebody goes to change a saw blade--thinking that it's stopped...
The fanblade is synchronizing with the camera at times. Reminds me when we took readings on our pumps using a strobe light...the blades would look like they were stopped.
So I guess during normal operation you would lock in the clutch and rev the engine up and idle back down repeatedly? Or were you supposed to bring the engine up to speed and slip the clutch in and out like in the video?
Apparently, these things produced soo much sound pressure out of the horns, that anything in front of it, like grass, could catch fire. It's painfully loud
hOW DID THAT THING WORK? Did they start trying to crank the engine when NORAD detected the bombers taking off in the USSR; and finally get it yowling about the time the first one was on its way down? Seems like a whole megillah for a little drone.
@sacheus the chrysler air raid sirens were gas powered from new.los angeles county and probably others converted them to run on propane which was much more reliable for starting.therewas no loss in performance of the siren
im in canada and a friend of mine has one of these we are trying to get back up and running the engine needs a rebuild since its been left abandoned cant wait to fire the thing up and hear that siren sing once more with the beating heart of all those bald eagles ready to fly
This is a victory siren not a air raid siren that was made in 1950-1952 and it had a l8 engine wale this has a v8 (yes i know that they were both air raid sirens i am talking about this one's predecessor)
What if... you replace that weak HEMI... With a GAS TURBINE! Because the HEMI=180 HP, while a gas turbine like a GE T58 has only a minimum of 1,250 HP!
im going to build a customMack v8 and a bigger air raid siren the motor will have 12 inch stacks to make it sing.could some one help me fin d a big siren for it??
Talk about a siren on steroids. If you do not think an air raid siren power by a Hemi V8 qualifies. Then I would say you a wrong. It's almost a shame to use such a great motor for this siren. I wonder what the siren would sound like powered by a Blown Nitro Methane NHRA dragster motor? It might be more (RPM's) than the siren is able to handle.
That 331 hemi was not considered a high power motor they put them in luxury cars 1950's. Later the 426 hemi was the high performance. I think at the time this motor was used for a lot of things including air-raid siren's.
This is a standart setup. They where buildt like this. The sirene is actualy a big fan. And a fan like that needs a lot of power. If you reach a higher rpm the pitch wil change. But it wil not produce more sound. But its realy old american technice. If you need to power it you use a V8 :-).

Why do so many people refuse to rev one of these to full blast? Come on!
The Chrysler Air Raid Sirens produced 30-32 dB when maxed out. If this was reved fully, the siren could possibly blow someone's eardrums out.
Only "32 dB"? Um, no, Sparky Junior, you've got it screwed up. They sounded at a whopping *138 dB* at full power (measured at the standard 100 feet away)! They're the world's loudest sirens!

MaxxFordham I'm saying if they were to sound it off,at full speed, as a civie would be walking by, it would blow the ear drum.
Only if they were really close and without hearing protection, Sparky Junior. I'd like to see a time when they're prepared to do it.

@@hamitcampos4989 Well no the engine revolutions make the siren disk go faster and more louder
Fast forward to 3:20 and save yourselves some time.
but the engine sounds beautiful anyhow
Love the rolling-shutter effect on the fan.
We watched one being run up in Halfmoon Bay at the show at the airport. It actually lifted 3/4 inch gravel off the ground and made it dance like it was water on a hot skillet. Made your knees buckle darn near
Is anybody going to say how nice this Chrysler V8 sounds?
OH WOW THIS IS COOL IN ALL WAYS!!! I love Chrysler and I love air raid sirens!!!
Sounds more like an old plane flying over!
old man* farting* after eating a burrito*
Because it's not at full rev.
love the warp of the fan blade spinning lol
you realize that this was made back in the 1950's right?

That fan blade though!!!
it is a optical illusion cause by the shutter speed of the digital camera.That fan is always going at engine rpm.
I'm aware of that. Doesn't change that it looks cool.
Yet I'm the one with an engineering degree.
James Willich wow you must be proud of yourself
It's going to be funny as hell when it grenades and throws shrapnel everywhere
Had one installed in Lomita ca. They told us they couldn’t test at full speed it would blow out windows for a mile or more
The small hydraulic pump at 0:39 powers the turntable.
This monster could lead the tthunderbolts to victory
0:46 seconds Reminds me of workplaces where the power tools are run on the same power grid as the discharge lamps and somebody goes to change a saw blade--thinking that it's stopped...
Brent Fisher - Remember setting the timing on your old car using a timing light? Every man alive touched the fan. 😳 ONCE.
@@blipco5 Don't mess with a berserker...a bear messed with him...once.
Can I borrow that to scare all the deer from my neighbors property over to mine this hunting season?

Awesome machine - I need one!
Interesting that the drive line U-joints don't employ the minimum operating angle to ensure long life.
so when these were installed for use how did they start, if there was a attack did someone go around and manually start the engine up?
Can the Chrysler siren shatter glass?
@sacheus the chrysler air raid sirens were gas powered from new.los angeles county and probably others converted them to run on propane which was much more reliable for starting.therewas no loss in performance of the siren
I sure hope you guys wore ear protection
is that the thermos stat kicking in for the engin water i noticed the water dont flow all the time
open the throttle and blast the big fucker to 138 dB's it sounds much higher pitched and i love the V8 hemi engine
Just geeking out watching the cooling fan
@shorttman1968 the siren or chopper unit was made by american blower corporation.
were these all gas or petrol run so as the gas would never be off.
Yeah that's the Hemi 331 on it. Most of the later Chrysler Air Raid Sirens had the 331s, though some had 318s and others had an inline 6.
engine runs just fine thanks,its the short pipes and no mufflers that your hearing!and you should hear it when your right next to it!
The camera shutter is cool!
A nitro burning fuel Hemi would make that thing bark.
Like it doesn't already?!
More is better.
+Thebuilderofthings1 AW COMEON!!!! THEY SHOULD'VE ET IT RIP!!!
is there a specific model of the actual siren part.
i would love to see the chopper from this siren
These were powered by Propane gas, which doesn't go off like petrol would.
Cooling it with a garden hose?
Holy crap.
came for the air raid siren, stayed for the Shutter effect on the fan blade...
totally cool,i wish i had one,oh wait i do!see this siren running at car and airshows around the so cal area this summer
they said that this was loud enough to turn fog into rain O__O is that true
***** XD
***** lol the new slogan "Chrysler Air Raid Siren. Getting you naked for your safety" XD
+EpicEverythingDude75 What kind of siren is your profile pic?
Lukas Evans It's a vintage ACA Allertronic siren :-D
Is there a yt recording of it somewhere?
im in canada and a friend of mine has one of these we are trying to get back up and running the engine needs a rebuild since its been left abandoned cant wait to fire the thing up and hear that siren sing once more with the beating heart of all those bald eagles ready to fly
one of the best v's ever buit by crystler! crank it! it ain't gonna hurt it!
There’s a spinning mechanism that makes the siren wail.
This is a victory siren not a air raid siren that was made in 1950-1952 and it had a l8 engine wale this has a v8 (yes i know that they were both air raid sirens i am talking about this one's predecessor)
Yes, a 331 Industrial Hemi, based on the automotive 331
So that's whats creating all those sounds at night people are catching on their cellphones.
i want to meet the guy who decided, "ya know, these electro-mechanical sirens we have just arent doing it for me. Lets strap a hemi to this mother!!!"
It sucks how butchered the audio quality is, those V8's sound amazing
At full blast this thing puts out 178 decibels @ 1 foot. Holy christ Krakatoa eruption was 180 db.
So you are located in texas?
FIre Station 5 just up the street from you used to have one on a big tower. (Rosemead/Huntington)
Is it pissing gas???
What if... you replace that weak HEMI...
With a GAS TURBINE! Because the HEMI=180 HP, while a gas turbine like a GE T58 has only a minimum of 1,250 HP!
It would probably be heard in Japan
Why not try pulsejet engines? They blast gases with extremely high speed at sound frequency, so they're nice noisemakers themselves.
Do you guys still have this siren? :-D
im going to build a customMack v8 and a bigger air raid siren the motor will have 12 inch stacks to make it sing.could some one help me fin d a big siren for it??
Why not just build the fan yourself, since you're going to fabricate everything else.
Whoa!!! That thing's got a HEMI !!!
im guessing it has a V8 engine 180HP
looks like a commando hemi running it.. jesus.. 392 ?
they were indeed hemi powered if i remember correctly
ya another site say 331 hemi, around 180 hp.. for a siren ? my goodness
Man after my own heart
That, is something else.
Don't stick your hand anywhere near the fan, OK ?
It must be almost as bad to have one and not be able,or willing, to run the sucker through its paces once in a while than not have one.
cool
i'll promote this vid
i would like to see this thing in full blast action
The fan looks slow
how come no one ever cranks it up? I grew up hearing the one at the fire station on rosemead blvd, and still miss that magnificant siren to this day..
I bet the This is Santa’s future sleigh
warning fpr headphones
this thing peaks at 138 dB like so all can see
run out of gas and you might not have enough guys show up!
This is a hemi V8 😳
That should've scared the enemy into not attacking!!
catman5169 ikr
I wanted to hear a wail but ok
Well that was cool !!

I wonder what the siren would sound like powered by a Blown Nitro Methane NHRA dragster motor? It might be more (RPM's) than the siren is able to handle.
I think the rotor would fly apart at those speeds, or the engine would fail because it isn't running with much of a load on it.

Every owner is always scared to put it full power. Probably because these things can produce like 170 dB fron where theyre standing. 😂
Blast the rain from the clouds,let it piss down on a democrat rally ,the essence of Detroit Mopar on acid
Have you ever opened it up all the way?
0:42
It's A V8 Generator
want.
NO WAY!
test thunderbolt hi lo
Cow siren maybe
I want the motor in a car
Atradies Inc. It's a V8 Hemi. Intended for car use. But adapted for siren
+Mavrick I'd put a turbo on it when it's hooked to the siren and rev it
id put that engine in a car ! :)
It's only 160-80 HP
wimps! crank that dame thing " it's a hemi!
wtf are you talking about?
cmon wind that joker up!!!!
331
The quality sounds like a potato
I dont like the sound of these, as cool as they are
Disapointing.....
I could find a way better use for that hemi.
This monster could lead the tthunderbolts to victory
