My father flew fighters for the 80th Headhunters in WW II, the P-38, 63, 39 all used versions of this engine. He always spoke of them with great admiration.
It's sure interesting to read the comments below, and see how much some people don't know ! For the record, I restored this engine and do know a little about it. Some errors appear in the comments. Firstly, the prop is not a test club but simply a cut down alloy prop which is a variable pitch type. However, I've got it fixed on almost feathered position so there isn't too much pull, especially as I run it up to take off revs (3000 rpm) for a short time. It is set like this to also provide considerable drag, and this way the engine functions correctly pulling approx 25 lb boost. The start up is prolonged, sorry, because I had a battery collapse and we had to resort to hand cranking it for the display. Usual start up is straight forward, switch on the inertia starter (you can hear it whirring up in speed), prime with fuel (a ki-gas pump squirts raw fuel into the manifold) and then engage the starter. Allison engines had a single stage supercharger, Merlins had 2 stage and this allowed them to fly at higher altitude, especially helpful over Europe. This Allison was a spare engine for the NZ P40 Kittyhawks which were used in the Pacific theatre of war, and didn't need high altitude. I hope you all respect the people who built these engines, they were the best you could get in 1942. Cheers. Doug
@@colinashby3775 This is a cut-down prop (some 0.5m trimmed off the ends of each blade and a great deal of the pull of a prop occurs from this area, so, yes it would really "stretch the towbar" if it was the full length, and at a take off pitch. The intent of my ground runners is to offer good load to the motor so they run up angry, but not drag me around the arena !! Glad you enjoyed it, Cheers
Allison V-1710 powered most U.S. Army fighters in World War II, including the Lockheed P-38, Bell P-39 and P-63, Curtiss P-40, and early North American P-51s. Love the Sound.
my dad told me once that they used to use the engines on deck of the carriers to navigate through the straits and tight channels. Immense power. great video thanks
This baby outclasses any street rod at this show. Hell Yes! God, I love that sound. Ear Candy! Thanks for posting man. 👍 P.S. he wouldn't be reving this puppy at full pitch. 😁 It would be by, by Ford..
@@daleval2182 they are hard to start. You develop a technique and most of the time it works. But if it doesn’t, you need to just walk away and come back later.
@@daleval2182 been there. I must be a true mechanic, can’t get my stuff fixed, I have a lawn mower and pressure washer that need the right choke. Also need to pump fuel bulb on mower to keep it running while it warms up.
I was at a car show at the West Port Plaza outside mall in St.Louis county, Mo. in the late 60s. This guy had one of these engines mounted on a trike frame specially built. It was amazing. It actually functioned as a moving vehicle, not just a show piece.. Haven't seen it since or anything like it.
In the late 1960's/early 1970's in New Zealand there were two boats that used these engines to compete in the Masport Cup races; Aquanaut a deep V hull; and Miss Tru Jen..a hydroplane. When the thunder of these engines rolled back off the hills at Picton Harbour it was amazing....
He has an amazing setup. Having the trailer and tow rig color matching is a really nice touch. Looks like a Ford Everest I think? That Allison engine, though it did seem hard to start made for quite a spectacle once it was running.
Like others, I first saw one at a tractor pull in the 70's. It was nirvana, as I was a WWII aircraft buff, thanks to my fathers service in the Navy as an aircraft mechanic, Hellcats specifically, or anything with a radial engine.
Andrew Loy , Andrew , my dad worked on the carburetors on these engines at a base in Italy in WW2 in Italy and received a commendation medal for designing a tool that allowed one mechanic to do fix the carbs in short order ! John
Será que podem me explicar oque é esse som que faz antes da hélice girar, esse som que parece que vai aumentando e para quando o motor tenta dar a partida...
davidca The Allison was BETTER than the 20 series Merlins that had the single stage superchargers just like the Allison !!! Only the 60 series, the HIGH Altitude 2 stage super charger topped the Allison at High altitude only !!! Under 20,000 ft the Allison ate the Merlins lunch, no matter the series !!!! Just the facts less the lies, hype and BULLSHIT stories !!!!
@MrAarovic the british want a plane that could escort the bombers the P47 COULD escort the bombers but their range is the problem same problem with the Spits
I was at the local county fair about 40 years ago, and I happened to catch the tractor pull. In the open class a lot of the guys were running duel Chevy 427s and 454s built to the max. But, one guy comes out with an Allison engine just like this one. I wasn't too impressed at first. It seemed like it was running rough and it even stalled as he was pulling up to the starting line. He restarted it and when he lit it up to start his pull... Goddamn... Flames where shooting about five feet out of the headers. The roar was so loud one felt it as much as heard it. He pulled the weight sled down the field like it wasn't even there and won the competition. To this day, I've never heard anything like it again.
You know that begs a question. Why not use these engines in commercial vehicles on the ground? Like imagine a tractor or semi with a Merlin engine. I would say use the Allison engine here, but from what I've heard these weren't quite the best.
As long as it doesn't protrude beyond the width of the trailer, then no problem. There are two of these trailer-mounted Allisons in New Zealand and I've seen both at the Classic Fighters Omaka 2015 and 2017 air shows. I never saw either arrive, so I can't say if the propellors are removed for road transport. In 2015, I was standing too close while they were running and the tremendous racket didn't help my tinnitis at all. In 2017, I made sure that I took earmuffs. Much better.
In the late sixties...an Allison powered car was raced at us 30 dragstrip. The driver was named airplane Freddy. Car did well enough. But took to long to reach revs for a really good quarter time. The legendary green monster jet also ran there.
not sure if this even needs a reply, shit i would be to embarrassed, please someone else tell this stupid fuck about drag racing, boat racing , and land speed records involving aircraft engines. has anyone else ever heard of old airplane freddy, i got to have another drink.
They kept them warm, tuned to a T and ready to start at less than a minute's notice. This engine is only started every few months and ran for a few minutes, not hours and hours in flight.
Radials are nice but issue with them is rotational forces, when under constant acceleration change of the engine speed like he was doing. even that thing was twisting pretty good would think a radial it would be even worse. small aerodynamic form factor was a big choice besides this motor is reversible also. :) mustangs are like flying engines the wings are purely there to point its thrust in a specific direction :) also imagine a big radial blocking your view if you had that on the front of a mustang (its already bad enough), I can see them used on a p-38 but not on a p-51.
something like this i belive. i dont know to much about aircraift piston engines, but i belive having the blades angle like that keeps the engine from overrev to. upload.wikimedia.org/wikipedia/commons/e/e0/Prop_feather.jpg
The propellor is called a test club and is used for engine runs to load the engine - it’s not designed for propulsion. You’ll also notice that the blades are at nearly a 90 degree angle of pitch on the constant speed hub.
The starting of this engine was extremely frustrating. It wasn't the person cranking, the guy kept engaging the starter before it was up to full speed.
Gives more elictrcal power, and it would be supplied through to generators power unit with 115 volt 400hz accordingly, very very impresive and inspiration.
I am surprised there was no backfire on her overrun? The RR Griffon 58 makes one hell of a racket when the throttle is choked off.Non the less a great video and sound.
