- Curtiss-Wright R-3350 32WA.
With very special thanks to Piet de Haan and his son Ed, who woke up this monster in 32 years after storing in container. Pier Francesco Abortivi for this engine, Willie van Dommelen for spare parts, Gerry Nielsen from Neptune Aviation Services, Inc. for propeller and all manuals, Greg Shepard and his friend Jean-Pierre Parizon, shipping propeller for small amount, Kim Slattery from HARS Australia for his very valuable advice, Jodie Routh from Aero Accessories, Inc. San Antonio for carburetor and starter, Wolfgang Dillbaum from aps, Mönchengladbach, Spacecraft Components, Las Vegas, Family H.W. Bogie for using their yard, my employees, my family for their patience and last but not least the buddies from Meerbusch Fire Brigade, where I have to apologize for the nuisance alarm after starting the engine with a lot of white smoke!!!
I imagine that thing would start running hot pretty quickly without any airflow over the cylinders.
Pluck-pluck-pluck-pluck-pluck-pluck-pluck... Man, I love the sound of a radial idle!
this is one of the best sounding radial engine videos out there, I love the sudden throttle at 2:11 and the flame shooting out the top exhaust at 1:32, I even love the turbo whine, even though I'm not usually a fan of that. great video.
The R-3350 has a supercharger, not a turbo.
@james west you are right AND Wrong ,, this engine is what's known as a Turbo Compounded engine
it has a 2 speed 2 stage supercharger but it also has 3 power recovery turbines these are similar to turbos but they do not provide intake air they are geared to the crankshaft through fluid couplings and actually return exhaust power to the crankshaft ,,each one of the PRTs is connected to 6 cylinders and is capable of recovering 150HP so with 3 of them that's an extra 450HP to the crankshaft
the PRTs are responsible for the turbo whine they are where the exhaust is mounted
Its the best cause we are hearing the engine without a prop.
This is unique because there is no prop interference with the engine sound.
The backfire at 1.32 literally killed me! Really sweet rumble, I use this video as a background music while I'm browsing. :D
No replacement for displacement!

Tib, son n law wood say th same wif big v-8s😊then kids put turbos on small Hondas 9 + seconds, 149mph quarter mile.
I was in the U S Navy from 1967 -1973. After active duty, I was assigned to V-P 94 at NAS New Orleans.The squadron had P2V Neptunes assigned. These planes had two of these engines, plus small jet engines that ran on 115/145 also. I was an ADR 3rd class, and I worked on these engines. Nothing like a big stacked radial at idle.
My dad was an aviation machinist's mate in VP-47 at NAS North Island (San Diego), till 1957, and before that at Kaneohe Bay in the late 40s, working on the P5Ms and P5M2s. He was also occasionally flight engineer when they took those beasts up, and mentioned that it took eighteen hours to get from San Francisco to Honolulu at 125 mph.
Killer engine. Strange hearing the thing run without the prop sound to go with it. Cool turbo whine. Sheer music!
Yesss, a symhony, played with several instruments, 18 pistons, 36 valves, two counterweights, three power recovery turbines, an elecrical starter and an external fuel pump.....
Shouldnt a small prop be used to cool the engine down. There is a lot of heat emanating from the engine.
Hi,
thanks for comment. Yes, you are right. We are watching CHT-Temperature (Cylinder Head Temperature) very carefully. Temperature of top cylinders should never exceed more than 240 degrees, otherwise you have ignition without spark plugs. We are working for cooling engine with a cut off prop.
One of the most beautiful and best sounding engines ever created!!!!
Hi Joe,
it`s not a stupid question: First, this engine formerly runs on AvGas with fuel grade 115/145, a highly leaded and purple coloured fuel. This fuel specification is so specially today, that it is only produced for events like air races with its high-performance piston engines. For our "show-runs", we will burn Shell V-Power 100 or equivalent fuel with antiknock additive, because, we don´t ask power.
Before you can start the engine, draining off oil from the bottom intake-pipes and bottom cylinders will be required, preventing a hydraulic lock. You have to remove the spark plugs and three plugs from intake manifolds to do this.
After this procedure, there is always an amount of residual oil in the cylinders and manifolds, that will burn out after starting the engine. That´s the reason for white smoking radials especially after cold starts.
Regards
Andre
turbocompound Very interesting piece of information.
wrong aviation fuel is 100LL 115 145 was stopped years ago. This engine will runn on 100LL, or even car fuel as they are running it there, fly? No.
yes 115/145 was used in the AD Skyraider around 700 gal would keep it aloft for around 8 hours , long enough to use up the 31 gal of oil it carried. 115/145 also made great Napalm with a little jell added..
That's good you were monitoring the head temperatures, I was getting concerned the engine was going to burn up with no cooling air. Even a barn fan or something would help out. But who am I to talk about running an engine without cooling air, though I did limit my FrankenBriggs 4 cylinder to a 40 second long run. I have also made a Tubo-compounded Briggs engine :)
Sweet engine run!
Wow, that rev-up, DAMN! Imagine these engines running for many hours as they did in the aircraft they powered.
Normally a club-prop is used to generate some airflow through the engine and to provide some load on the engine at the same time. Especially with a multirow radial that is not unimportant because the main rod and cascade gears for the timing can otherwise get damaged.
But not having the prop in this case provides a very rare clear engine sound example of this highly complex compound engine with supercharger and PRTs.
Absolutely love it.
Those engines sound fantastic the really make it thunder gotta love Wright and pratt and whitney and rolls Royce as well as many other manufacturers of those days all the giant aircraft engines are thrilling
All it needs is that prop....This is way to cool..
She’s just beautiful. Great work!!!!
The B-29 Superfortress had four of these babies
I thought b29 had R4360 wasp major engines
These engines sound incredible without a propeller distorting the noise. You can hear the supercharger whine which is very cool.
Had these on C-119 D ,3 fluid drive turbos .3350ci put out 3350hp. Flight mechanic EAFB 58 to 62. 🤠
radial engines are of beautiful sound and design, awesome piece of footage, job well done
❤ That Bad A Idle!!!! Sounds like my nasty 406 SBC big A roller cam radical choppy Idle! And ⚠️ BTW the term "Holy Smokes" for some reason came to mind when it fired up! Wow them bottom cylinders and valve seals definitely allow in some oil into the combustion chambers! I know that they'd have to hand crank these radials over by the props to be sure they weren't hydro-locked by too much oil in one or more cylinders! But this shows everyone exactly why the ground crews would run them props over a few times lol!
Great video, and I really appreciate all the answers you have given in the comments. Keep up the good work!
Great job! Love the sound of the round engines.
Impressive and what an engine. Hurts a bit though as I have the impression that they are "Cookig Up" that engine - "No Cooling"
Hallo Proficiat - waar een wil is is een weg -
Echt Perfect gemaakt. Super !
Thats one engine that needs a prop to smooth it out, sounds like it's got a full race cam in it!
very nice! Even the PRT's sound fairly healthy...
Hi David,
in 32 years after first run, engine sounds good. Have a look to second video, there it sounds already better. Now, we are working on fine tuning.
Andre
My grandad worked on these engines!
She just wants to make sweet stinky power. You can tell by the sound
This is what is known as a "turbo-compound" engine. The turbos have NOTHING to to with airflow. Instead, they (3 of them) are linked to the crankshaft thru a fluid coupling, imparting additional power to the prop.
Lowell Goodyear if you want to see a modern interpretation of the turbo compound system, look at a Detroit Diesel DD15 engine in a semi truck. Same system.
Strong eng ,after touchdown reverse props wood not bog engines down. Plus th water alcohol injection for takeoff.
Seeing how much oil came out the bottom exhaust when it started, I'm guessing oil that leaked by the bottom pistons as it sat since its last run; is there a procedure for clearing any oil before starting to be sure the lower cylinders don't hydrolock and break something? Such as a mechanism to hold the exhaust valves open while you spin it over a few times, etc..?
No prop ,no overheat ?
I know what the difference is between a supercharged and a turbocharged engine, but I'm still not quite sure what the difference was between a turbocharged engine on a normal fighter and the "power recovery" type of turbocharged engines on the Super Constellation and DC7. They called them "power recovery" turbines, but aren't all turbochargers, by definition, "power recovery" devices? What's special about the power recovery turbines on Super Constellations and DC7s that makes them different from other turbocharged engines?
Radial engines are the shiznizzle!
I would think the engine would need the propeller blades for cooling. They are air cooled
Sounds like ya got some ignition problems there!
seems to be running sweet,
Amazing!!!!
Hopefully they put the cut blades on this monster after this so as to cool it in future runs.
Brooks Wolters Don't worry, now it has one and engine is in best condition...👍👍😎😎
Brooks Wolters
Great way to over heat the thing ! 😢😢😢
Three years in P5M squadrons I heard many a R3350 start up.
Imagino um motor desse servindo como gerador elétrico. Acho que abasteceria uma cidade inteira!
Mes salutations chers amis pour ce magnifique partage .concernant le moteur puissant en étoile.* pistons retatifs
Don't overheat it!
I love the sound of a fuck off radial " panting" Heaven!
Gota love a radial engine
beautiful engine !!!
Why did you do this? Is this a hobby for you? It is so nice to see this kind of engineering.
+carp614
Yes, it is our hobby keeping this engine running and saving this wonderful piece of engineering from a scrap press. We have a lot of fun doing this. Next part is, mounting a prop for better cooling and flywheel mass
needed to be stripped and fully rebuilt before firing it up again. The amount of oil thrown from the exhaust suggests serious valve stem oil seal and piston ring wear..
Looks like overfulled white smoke and the prop would probably make it run smoother Flywheel effect!!!
What about engine temp without forced air over the cylinders ?
Why do you guys run this beautiful and pretious engine without siginificant cooling?
Don't let the Greens see this :-P
....it's all compound fertilizer....😎😎
One engine isn't going to do any noticeable damage to anything, it's the global combination of every vehicle and powerplant that causes problems.
@@PistonAvatarGuy and cows
@@plot267 ALL human food production accounts for around 15% of the overall warming impact of human activities.
@@PistonAvatarGuy I think you'll find that animal agriculture represents 44% of anthropogenic methane emissions, the primary driver of climate change related to livestock, as methane is 34 times more potent than carbon dioxide over 100 years. Greenhouse gasses trap heat and are the leading cause of climate change.
Holy shit, sounds like a NHRA topfuel nitro methane dragster at idle😱
Magnífico!
*when you're talking like 1:35 straight, and you have to clean your throat... (1:36)
Kind of rough on the engine to have no prop on it.
No animals were harmed in the making of this video. Well, millions of mosquitoes probably killed, but that's it.
Is there a clutch mechanism on the power recovery turbines that they only drive the crankshaft and not the other way around? In other words If you turn the prop by hand or starter does that turn the turbines?
Yes, between shaft of the PRT and gearwheel of the engine, there is a hydraulic clutch. If oil-pressure is rising up after starting the engine, PRT and gearwheel are connectet due to flowing oil. It is working like a torque converter in a car with automatic gearbox. So a smooth running without mechanical vibration is guaranteed.
@@turbocompound Thanks, now I understand fluid coupling.
Power recovery turbines...
I'M GLAD THAT ENGINE ISN'T ON AN AIRPLANE!!
needs propellers for some engine load - and cooling
Omg that sound
Sweet !!
No test prop? Are you trying to blow it up?
it sonds like us school bus lol
does the it run alot nicer with a prop load on the engine? reason i ask is that i assume the plugs don't foul when the engine is under load?
Did is pass emission test?
Lars Birkemose
Definitiv; er hat Euro 7 !
Seems like it would get pretty hot running that long without a prop on it.
1:32 that blow
Fuck yeah!)
Cool, its going to overheat without a prop.
I am actually looking for a Curtiss Wright R-3350 Engine. We currently use this engine to create wind at our testing laboratory. any leads would be appreciated I am located in Ontario Californa.
kinda sounds like a V8 with a big cam in it. never heard a radial without a prop before
have to get one for my fORD truck
Engine stability , so make plans
Is there no issue with running the engine without a prop on it for load? little bit of oil burning off too?
+Todes Jaeger I've been looking into the radial engine last few days, from what i have found, the lack of load shouldn't be a problem. What is a problem tough is that an air cooled radial engine without a prop, doesn't get cooled enough, that's why i think they did not leave the engine on for a long time.
Im in no means an expert tough
Now engine has a prop with short blades.
Seems a little lean at cold start or maybe no enrichment at tip in.
This thing kind of sounds like a muscle car engine when it was being revved really high.
Nice Flowers
....Yes, I agree. Wonderful Hortensien (in Latin: Hydrangea)......
*****
thanks for the data.
But the flowers behind make the video beautiful, easy to watch
Epicness +1000000
How did that engine not break apart with out the props to absorb the vibrations of the crank shaft?
metamaster1492 Now, engine has a prop. Engine always ran smoothly without any vibrations. We didn't ask any power and crankshaft never exceeded higher rpm. All important parameters we watched carefully during our test runs. So, don't worry, engine is in best condition.
metamaster1492 THE PROP HELPS AIR COOL IT AND RUNNING UNDER A LITTLE LOAD
Without a prop won't you have cooling issues?
the motor. the motor
Love the sound of a Diesel engine.
it runs on gas.
Was that oil dumping out of the exhaust?
Also, stupid question but what kind of fuel do Radial engines run on?
+o0DraastiK
Yes, most likely oil coming out of the exhaust. And just about everywhere else as well!!
On a cold startup, it was common to see an oil slick from the nacelle all the way back to the trailing edge of the flaps and dripping off the end.
Typically, the R 3350s in the DC7s I flew would burn anywhere from 1 - 4 gallons of oil per hour.
There were 2 old sayings about the 3350s......'if it ain't burning oil, it's because there's none left'....and when we'd pull up to the fuel station it was 'fill er up with oil and check the gas'.
Lol.
Originally, they used 115/145 avgas (purple fuel), but since that is no longer available, they now use 100 low-lead (blue fuel). With the reduced octane, the ignition timing was retarded a bit and high speed on the supercharger is no longer permitted.
Very high octane leaded gasoline.
Radial engines require a special fuel formulated just for radial engines. Same goes for inline engines, opposed engines, V engines and rotary engines. One must be very careful because it could cause extreme fun and out of control laughter.
It's all very interesting. Thank you!
Neil Anderson , Another dumb question: what is the highest octane rating and in what engine is this used?
How is it being cooled with no prop wash?
Hi Paul,
at the moment, that's our problem. We only can run the engine for a few minutes by watching the cylinder head temperature of the top cylinders. Don't worry, we don't overheat the engine. We are working on a cut-off prop for mass and cooling.
Thanks for your answer! I thought cylinder head temperature was an indicator for mixture richness...or was that EGT?!!.....I was just concerned about temperatures elsewhere, like cylinder barrel bases and crankcase.
With exhaust gas temperature, you can read the fuel to air ratio as well. For gasoline fuel, the stochiometric air-fuel mixture is about 15:1, that means, for every gram of fuel, 15 gram of air is required for full oxidation. If you run the engine on that mixture, it's heating up very fast. You can read this on high EGT with the result of fast increase of CHT. To prevent overheating, engines are running on fuel to air ratio less than 15:1, that means, mixture is more rich. Sorry, but explaining in English language, is not easy for me, I'm German, but I hope, you will understand it.
***** English is fine! Thanks.
Paul Fabrique Thank you Paul.........
Is that wise to run a giant air cooled engine with no air flow 😮
Will this fit my honda
what's that liquid coming from the exhaust right after start up?
Hi Mark,
if you stop the engine, an amount of oil will be left in the crankcase. This hot oil is passing the pistons of bottom cylinders an will accumulate in the intake and exhaust stacks. Restarting the engine after longer shutdown, this oil is blowing out through the bottom exhaust pipe during first seconds. Standing behind the pipes during starting prcedure will make you look you like a crumble cake....!!
Вот это звук!!
Where does someone find an engine like this to buy and restore?
and a what cools this huge motor
Air
is it bad to run it with no load ?
2,200 hp at 2,800 rpm (takeoff power) This engine was only revving to about 1,500 rpm and no it's not harmful at these revs without a propeller load. These guys know what they are doing. read the info at the top. Do you have a car? Do you run it with no load, i.e., at idle? Do you even rev it at standstill occasionally?
Who else notices the oil leak
It's supposed to do that
Andreas, bist Du das?
Axel Knoetig
Der Motor ist meiner, der junge Mann im Vordergrund Edwin de Haan.
It's going to overheat without a prop, it's air cooled!
how much petrol does it need?
Star Light If engine is running with 1000 revs, it will need 1 liter per minute. If you start cold engine, it will need 4-5 liters until running smoothly.
turbocompound is that a lot?
That must have been loud
B29 engine?
