Thanks for this comment; I'm happy with what you wrote. I love radial engines, their sound and showmanship. However, it's never easy when I record races because I'm always afraid that the microphone will be damaged. Inside this microphone, I have a noise limiter that automatically activates to avoid damaging it, but as you well know, recording the sound of these motors is the most extreme thing that can happen to these electronic devices. Fortunately, so far, the microphone has done its job admirably.😉👍
i know how you feel, finally seeing that tractor in hd or anything else, a car for example. I used to look at the Dragonfire puller like wtf is that radial engine. Never saw that in hd
@@Nightwing690 Only at high power settings. At lower power settings, the propeller doesn't beat the air as hard (nor do the blade tips get close to the speed of sound). Ever heard e.g. T6, an AN-2 or maybe even a Ju-52 rumble past, taxiing out to the runway?
As an aircraft mechanic I find this use of these powerplants to be interesting. They are aircooled needing forward flight to stay cool with a large propellor. Compression ratios are relatively low, so the methanol fuel mixture must be to keep them cool. Working on radials is very labor intensive and there are lots of things to go wrong with 70+ year old technology. Pretty wild.
I was waiting for your comment; you are the right person to answer. What you wrote was said to me by a mechanic who takes care of the maintenance and modifications of the Italian tractor called Joker, and that you see in the video. He's a very knowledgeable and stubborn person and continues to work to improve engine performance.
@@Italiansupercarvideo Knowledgeable AND stubborn is what it would take to keep those things going! Finding parts would be quite a challenge, little rubber couplers and seals, things that don't age well. He is doing a good job to keep it going!
@@upsidedowndog1256 He's truly a mechanic with two "golden hands" who likes complicated challenges, and it's no coincidence that he has chosen a radial engine to be mounted on this tractor. Of course, he knew it would be complicated, but he's someone who likes challenges, and from what I see, after a lot of work, the tractor works well and has room for improvement.
Sono tutti motori Curtis-Wright radiali, non ci sono Allison, però sono felice che il video ti sia piaciuto 😉👍 L'effetto dei "lumini" notturni è davvero bellissimo 👍 Sono tra i motori più spettacolari che puoi vedere nel tractor pulling 💪
Many years ago, I flew DC-7s as air tankers that dropped retardant on forest fires. These planes had 4 - R3350s and if I remember, each engine would produce 3400 HP for takeoff and 2800 or 2900 HP continuously. 2800 or 2900 RPM. They were supercharged, 2 speed. Low speed was for under 12,000 feet and high speed was for higher altitude. At takeoff on a hot day, the manifold pressure was just short of 60 inches. They had the turbo compounds, also known as 'power recovery turbines' too. Mechanics absolutely HATED the PRTs, apparently they were pretty hard to work on......... They would burn from 1 - 4 gallons of oil per hour during normal operation and leaked quite a bit onto the ground when they were not running. An old joke was 'fill it up with oil and check the gas'........lol The propellors were 14 feet in diameter. There was a gearbox in the front that was 16:7 engine to prop. They burned 115/145 avgas, it was purple. Since we flew only in the summer, the oil was 80W. It was 60W for winter but there aren't forest fires in winter......At normal cruise, they would burn around 100 gallons per hour. If you treated them properly, they would give very little trouble but they were not very tolerant of any sort of abuse. Especially applying takeoff power when the heads and/or oil was not up to temperature yet. These engines were designed in the mid 1930s, the first one ran in 1937. They didn't have computer drafting back then, not even calculators. If close was good enough, you used a slide rule, if it needed to be exact, you wrote out the math on paper. Pretty amazing for an engine that would produce more than 1 HP per cubic inch of displacement. This video brings back very fond memories of these planes and the engines that powered them........
Thank you very much for this comment which I have read very carefully. You are a competent person. What you wrote I read on the internet to document me about these engines, and you wrote everything exactly. I'm happy that some "crazy" has remembered these engines in modern times and that now they find a second life in the tractor pulling championships. The spectacle of a running radial engine is hard to beat; perhaps only helicopter turbines in this sport give the public the same awe.
Ja, Sie haben Recht, trotz des hohen Wartungsaufwands haben sie eine zweite Anwendung bei Traktor Pulling gefunden. Sie haben ein enormes Antriebsdrehmoment und sind daher perfekt für diesen Sport.
It's insane seeing the kinds of torque these engines have at 2000RPM considering they made so much HP, and are making even more with over driven superchargers and methanol. Also 5:27, you're supposed to keep the nitrous a secret.
Spettacolare questa disciplina. Ho visto che c'è stato un evento ad Agazzino, a pochi km da casa mia. Nei dintorni di Piacenza, c'è un trattore tipo questi, non so però che motore abbia, sicuramente di derivazione areonautica.
Ad Agazzino si svolgeva una tappa del campionato italiano, è sempre stata una bella gara con tanta gente. Forse ti confondi con Parma, ed il trattore Starlight Express 3 che monta il Motore Allison da aereo.
@@Italiansupercarvideo Non so che trattore sia, ma lo vidi dalla strada, nell'aia della azienda agricola qualche anno fa. Mi dissero che faceva il campionato italiano di pulling. Altro non so. L'azienda è sulla provinciale che va da Piacenza a Cortemaggiore...
@@YuriBruschi Sto andando a memoria, comunque dopo la Romagna, la zona Parma-Piacenza è quella in regione dove c'è l'altro zoccolo duro di appassionati/creatori 👍
Sure they are the most spectacular, but over the years, I have always seen tractors with even more V8 engines do very well and win and those with turbine engines quite well.
@@justinmanse2849 As soon as I have the opportunity to meet the Italian team that has one of these tractors with a radial engine, I ask them a few questions.
I don't use Fakebook. I can only "follow" you here. So post more videos. Radials kick ass. Can 3350's be paired? 36 cylinders. Frankenstein. It would absolutely destroy all competition. Including zvedza dragon fire. It would be the final word in tractor pull. Unless somebody paired a couple zvedza's. 84 cylinders Insane. Need a bigger lead sled.
Thank you for following me. I should be following some tractor pulling competitions this year, so I hope to publish some videos soon. Also, I'm a massive fan of radial engines 😉👍
I notice on the radial engines one of the pit crew flips a lever on the carbuerator just before the pull and many times someone flips it back at the end. Anyone know what that lever is for?
I have been thinking the same.. I think it is mixture lever they switch from lean to auto-rich/full rich (there was this kind of lever in the airplane cockpit too. Rich mixture for takeoff, lean mixture for cruising). Driver has no time to do that by himself?
The question is interesting; I can't give you a precise answer; perhaps the mixture of fuel composed of aviation gasoline and methanol generates this smoke.
My guess would be both fuel mixture, as stated above, and tuning. These are supercharged to high pressures stock and probably even more so here, easiest way to keep a boosted engine safe is to tune it fat(rich) and as difficult as it is to get parts for these, it wouldn't surprise me if they ran them fat for longevity

The sound of the propeller drowns out the actual engine sound.

Yeah, one of the most spectacular engine in tractor pulling races 💪👍
If you don't like the sound of radial engines then I guess you must have never had sex.

@@Italiansupercarvideo Hai perfettamente ragione. Mi ricordo le gare di arature, più di 40 anni fà !!
These engines do NOT have turbo compounding-you can see the exhaust from each cylinder is directly exhausted to the air.
Yes. There is only super charger. I Havent seen any turbo-compound radials in tractor pulling..
are these engines better then the multiple v8s and turbines used in tractor pulling? thanks
Sure they are the most spectacular, but over the years, I have always seen tractors with even more V8 engines do very well and win and those with turbine engines quite well.
What is the lever the crew pull up before starting and back off when stopped?
I can't tell you exactly; maybe they open up a massive influx of fuel?
@@Italiansupercarvideo kinda seems that way tried looking it up there’s not much info on radial tractors lol
@@justinmanse2849 As soon as I have the opportunity to meet the Italian team that has one of these tractors with a radial engine, I ask them a few questions.
what are they setting/adjustinf right before and after the pull ? Mixture?

those engines sound soo evil.

Chega formar shock diamond acima dos tubos de escape.
why are they smoking in pullers ? Not that much smoke in aircrafts

Heaps of boost and fuel makes hp,and rich mixtures are a little safer.
@@carstennobody7047 the octane doesn’t change
ua-cam.com/video/cY9hTg0N0Ek/v-deo.html ...Are there mach diamonds in the exhaust plumes?
Some of those are running so pig rich. Black smoke everywhere. Way to rich for good power. Don't they know how to tune these things?
Not a whole lot of wheel speed that is typical of the diesel pulling tractors... 🤷♂ It just kind of bounces around and unloads the tires. 🤔
I don't think these engines are very well suited for tractor pulling .
