I believe they're giant clutches feeding into 1 transmission

If you’re still interested, Phillip Kaess‘ chanel featured them. It’s in german though. Basically huge flywheel-clutches joined by huge straight cut gears. Only one gear and reverse gear.

@@peteharder6325 That is correct!

Those engines powered the P-38, P-39, and P-40. They powered the P-51 until some Brit test pilot said "I wonder what would happen if we stick a Merlin in this thing?" The Allison wasn't a bad engine. Allison was told to not bother developing a supercharger. GE would handle that. GE fell short.

Homemade - basically the same as what is used in a Top Fuel dragster. Check Molinari clutches.

theyre actually 16 inch lol

LOL I know right. Little bitty things. Each engine weighs 1,595 lbs.

And if I am not mistaken, don't they have overhead cams and 4 valves per cylinder?

24 cylinders they are two V12

+soaringtractor Actually, they're not "fighter" airplanes. they were "Pursuit", thus the "P" nomenclature. You should have known.

+soaringtractor But all of us aviation nuts will always remember it as the P51. I'm not the aviation expert having only served in the US Army aviation rotary wing (helicopter) at Fort ill's 14th Aviation Battalion. My "birds" consisted of the Bell UH-1, AH1 & OH-58, the Boeing CH-47 and the Sikorsky CH-54 Skycrane. The Skycrane is still used exclusively by nearby (10 miles) Erikson Sky Crane fighting fires worldwide under a different nomenclature but whenever they're circling over the house or I see one, they'll always be a "CH-54" to me. It's the only rotary-winged aircraft I've ever flown in.

+soaringtractor I'm reminded of this old fart who claimed he flew a P-38 in Korea. He was dead serious! Speaking of Lockheed, my late best friend's late mother worked for Lockheed in Burbank, Ca. during WWII installing the nose cones on the fuselages. She had some funny-ass stories. She was tiny and Lockheed liked her because she could crawl inside the wings and do shit. One of her stories she was working on a Constellation and they pulled her out of it and wanted to test fly it. She told them if they flew it, the tail section would fall off (or wing, can't remember) and they brushed her off. Sure enough, when it landed, it happened. I know it sounds far-fetched but I don't think this lady was smart enough to come up with a fairy tale like that. I was her power of attorney and ended up with all her "stuff" (useless junk mostly) and one goodie was a mint pair of right and left-handed tin snips in a nice metal box. The box had a "Property of Lockheed" metal plate riveted to the lid. Nice aviation collectable! I sold it for $80 I think. Still have a little WWII-era Lockheed "stuff". She died at the age of 97 and was born in 1914.

+soaringtractor Yes, I can't afford a publisher. Why? You got a problem with that? What does that have to do with aviation? Are you mental?????????????????????????????????????? You should have known.

+soaringtractor "Free"? I wish, kid! I personally pay Charter Communication $117 a month for the privilege to mock you kids! How much does your Mom pay for you to play on the computer, kid? You should have known.

I heard a comment by the team that they think most US teams didn’t put enough engineering and evolution into the Allison engines. The engines used today are heavily modified.

WW2 Airplanes Allison V12‘s

These are both allison v12 engines from planes

+soaringtractor 'No Replacement for Displacement'

OLD SKOOOOOOOL=BEST SKOOOOOL!!!! BRO!!!

The plane racers have used most of them up. The ones left are super expensive.

n. woody The V12 engines are definitely becoming as scarce as hens teeth and costing nearly there in gold or at least silver. I remember back in the mid to late 70's about half the unlimited tractors in the US were powered by V12 and the rest were split between Hairdryers and V8 that had there cranks bolted together and timed as 16 cylinders and now and then 24 cylinders engines or some off the wall power plant that the tractor owner dreamed up. Now most all pulling tractors are Hemi V8's of some form or Big Block Chevy's all plumbed together the same way. I am not taking away from the new tractor engineering design but truthfully they don't style and attitude or ingenuity but that is just my opinion and opinion are like certain body orifices everybody has one.

Yes it is.

If you meant @ 8:18 then it's "We Are The Champions" by Queen.

we are the champions by Queen is the song playing around the 8:50 mark

Do you mean "Maria" from Scooter? kzfaq.info/get/bejne/a5eSm6VoqrGslIU.html Please do not look up the "lyrics" as alway with songs from Scooter.

***** Thanks Its a great song.

Yes they are. Lot of torque and Horsepower

Not to mention 4 valves per cylinder

In german its called „Bremswagen“ translated it would be „Breaking Wagon“

Less force needed to turn them? Just guessing.

so it's harder to flip it by making the centre of gravity at the front axle closer to the ground.

mitchamus Hm... is that a definitive answer or just a guess? Seems to me they could just place the axle higher with a larger wheel to keep CoM low. I'm guessing it's something to do with some rules they have to follow.

Categories are in part determined by weight, that is why the rest is also made of no more then tube frames. And the more weight you save the bigger your engine can be.

My guess would also do with weight savings. But also they can build a more stout, small wheel tire that can live up to all the load being thrust upon them as the front crashes down. So durability and strength.

M8fv lp, ij5 gute

SANTYU🤘

All the power is sent to the back tires. No need for (expensive) large front tires.

one Allison V12 about 2800hp

nope it was 5600 hp

Jack Notts over 10 000

@@RundUmsGamen yea both together but one is 2800hp and 2800hp+2800hp is 5600hp

They are two V12 Allison Airplane Engines
