The Engine That Won World War II - Jay Leno's Garage

[@IRONHORSE427RACING]

A old mustang mechanic from WW2 lived not far from us when I grew up as a kid. He got me interested in Hot Rods mostly due to his old Flat head Ford Pickup with a Offenhauser headed Engine and 3 -2 BBL carbs anyway he had bought a decommissioned P-51 Mustang from some place in South America and had it shipped up to the middle of Nebraska complete with it's Packard built Merlin and I was there the day he finally got it all reassembled and started it for the first time....it leaked oil and av gas several places so after making the needed repairs and tightening of fittings it fired right up and he and I taxied it on his home built grass runway behind his barn turned shop...the wheels lifted off the ground on the return trip down the runway and I saw daylight in the setting sun under the wheels....then we safely taxied it back to the barn and a little over a week later he flew it to his Brothers Farm in Northern Missouri where he visited for a couple of days before returning home in it. He landed it safely parked it in his barn and it sat there for the next few years. He faithfully started and ran it every week or 2 till he sold it to a War Plane Collector some place in Northern California I think he told me. Funny thing is he never had any children and his only wife died at the age of 64 so most of the time I spent with him it was just him and me working on hot rods or that Mustang.....when he passed some years later I got a call from his Atty. Telling me he had left me his entire accumulation of tools and that 1950 Flathead Ford pickup. His Brother's family got the house and farm and had a huge auction where many of his treasures were sold to the highest bidder but I got the tools and Truck and still own them all today. Someday I will pass them on to my Son but man the greatest gift he gave me was his friendship, patience, knowledge and experience....that and a ride in a real honest to goodness Merlin Powered P-51 Mustang ! the greatest gift of all.

[@IRONHORSE427RACING]

@Chris Banks I know I did.....though it would have been Perdy nice to have the Mustang too....lol Our Son asked to borrow the Flathead one day and about a Month later brought it home.... wearing a bright new shiny paint job...(he used it as his Senior Auto Shop Project ) and completely re did the body and Oak plank Bed in the Box of the Pickup.....it's still my Daily Driver and has well over 200,000 miles on it now total but people who are alot sharper than me about those Flathead Pickups are always telling me it looks better now than when those trucks were brand new....and I gotta take their word for it.....I know this much.....for how heavy it is.....it's still really fast and sounds fantastic.

What an awesome story. Thanks, for sharing.

[@IRONHORSE427RACING]

@@starfighterusscv-6693 I was afraid when first posting this people might think me a Liar of the first order but interesting thing is I have a whole photo album we put together of him and I working on the old war bird...(that was what he named it)...he let me have my High School Art Teacher come out one Saturday Afternoon and paint a nasty looking Hawk that was black above and brown underneath in flight with leather flight hat on diving under the name on both sides of the nose) it had a black and white checker board design on the tail and lower rear fuselage and a blood red nose cone with the flat black top of the engine canopy right up to and around the cockpit.......anyway I have bunches of 110 kodak instamatic photos in the album from the very day it was delivered on 2 semi truck flat beds and a Van Truck...right up to the day we said our goodbyes to the plane when it's new owner hopped in her and pointed her nose to Sunny California several years later......I know it went to Santa Monica but from there have lost track of it in the years since. I only hope it's still flying someplace giving the thrill of a lifetime to people like it did to me....my only regret in this life is I didn't take him up on his offer to teach me to fly it....who knows I might own it today yet if I had. Someday if I ever run into the old girl I will make a present of the photo album to whoever owns her now.

I lived half a mile from the National Helicopter Museum so was used to odd things flying around. One dayI heard something very different. Two P-51 Mustangs buzzing my street at a couple of hundred feet, went out to watch and they did it 4 or 5 times that afternoon. Turns out a neighbor knew one of the pilots. Priceless :)

[@robertcallahan6273]

Jay, As a long time aviation buff, A&P mechanic, and pilot, thank you for giving the Merlin another chance at life. The Merlin is one the most beautiful sounding engines ever built. In my early career as a mechanic I worked for Biegert Aviation out of Chandler AZ. We maintained a fleet of 9 Douglas C-54 (DC-4) aircraft outfitted for large area crop dusting for spruce bud worm in Main. Our typical contract was to treat over 1.3 million acres of forest. We had six aircraft on a two week start up and system check out for about two years. How cool is that for a guy just out of A&P school to be on a crew to start and run these classic aircraft every two weeks. The DC-4's were equipped with 4 Pratt and Whitney Twin Wasp R-2000 radial engines. With 2000 cubic inches of displacement and a two stage supercharger (much like your Merlin) it netted around 1450 HP @ 2700 RPM @ sea level. I loved watching your engine demo but I do have a suggestion on your starting sequence. These old engines start very similar to each other. The next time you run it try this starting sequence. -Master ON. -Pre-oilier ON until high regulated pressure reached. oilier-OFF -Throttle cracked, Mixture-Idle cutoff, Prop-High RPM, Blower-Low -Mags ON -Starter switch ON and count nine blades (this clears any fuel or oil out of the cylinders) -After nine blades, primer switch ON and hold, even after the engine starts, it will run fat but that's OK. -After its running, push the mixture lever to full rich position, once the engine starts to falter because it now too rich, Primmer switch OFF. Engine should pick back up and clear out. -Leave the mixture rich until the engine warms up. -After the engine warms up, idle the engine up as high as comfortable and cycle the prop from Hi to Low RPM, wait for the prop to respond, return it to High. Do this three times. -After this, slowly pull back the mixture until the engine starts to lag then back up a notch till it runs normally again. -Throttle back to a smooth idle This should make it a lot easier to start. I've been a fan of yours your entire career. I love watching JLG and how enthusiastic you are about all mechanical things car/motorcycle related or not. I'm fascinated with your Stanley Steamer. Keep up the good work and keep em running! Robert Callahan, Mesa AZ

That Lancaster flies right over my house every time the weather is nice, all summer long. You can hear those four Merlins coming from close to a mile away. Nice plug by Jay for the guys in Hamilton who do a great job keeping that thing in the air.

[@NickFortier]

I've seen that plane. A friend of mine is a framer, and as a carpenter thought I'd go work with him one summer. I forget exactly where in Ancaster we were working, but on one house we were just finishing the ridge when we heard the Lancaster . my friend told me his grandpa flew one in the war, and he and I both are still interested in history, and this is likely how he knew what plane it was. I swear to god it was flying so close to us at one point that it was as if we could touch it but j will tell you this; it was scary as hell! That plane shook our roof, and the sound was a lot like a top fuel car at the line. Just feels like it grabs you by the collar and shakes you. But yeah, that's as close as I've ever been to it, though I'll likely go check it out kn the ground one day:)

The Merlin does have a very distinctive sound, and I’ve visited the museum in Hamilton Jay speaks of in the video...Toronto is close to Hamilton. The Lancaster is something to experience...when they fly it, they “buzz” the museum, over an observation deck to put on a bit of a show, and it’s quite impressive. The museum is extensive with an impressive gift shop with many items covering a vast array of aircraft models, artwork, toys and memorabilia...well worth the price of admission. A flight in the Lancaster is $2500 I believe...maybe someday I’ll get a chance to go up in it.

P and W R-2800 was the greatest in my opinion. The P-47s smashed the Luftwaffe and killed the majority of their experienced pilots before the Merlin Mustangs arrived on the scene. It’s a common misconception that the Mustang beat the Luftwaffe but it was actually the Thunderbolt and it’s R-2800.

[@nabirasch5169]

The mustang, too. It was a flying dirge until they put a Merlin in it.

[@arcanondrum6543]

The P-47 Thunderbolt "Jug" was so good in its role that the A-10 "Warthog" is actually the Thunderbolt II in its honor. Air Cooled Radials can take ground fire and keep flying on fewer cylinders. Liquid Cooled Engines like the equally fabulous Merlin and then the Griffin were liquid cooled and could fly stronger where the air was thinner but one good shot to the engine block would leak out any hope of more ground support. The Radial and the Piston had their roles and they were reaching their maximum potential by late in the War. Ironically, Air Passenger Travel is well suited to a return to propeller driven aircraft given the lanes that airlines travel in and the lines for aircraft departures and arrivals at the airports. Their effective travel speed can be matched by a Mustang or Spitfire. There is a limitless supply of electricity available by drilling (about the same distance we already drill for Oil) to use the heat of the Earth to Boil Water (and Nuclear Power Plants Boil Water to generate electricity). For you doubters, the reason we don't already is because what was once a Utility Service is now a for-profit business that purchased all the infrastructure for fractions of a penny on the dollar "thanks" to Ronald Reagan. Once you turn that into a business, they will protect their profits - remember when Oil Companies claimed for years that Electric Cars were "too slow"? (Or when Tobacco Companies claimed that Cigarettes were "safe"?) Finally, a P-51 would certainly be used as needed however, Steven Spielberg is to blame for the P-51 CGI in his movie instead of P-47's. ▪

A few years ago outsiders who'd moved to the area near Bentwaters complained about the noise the Spitfire made; they'd obviously never lived close to an operational airbase. They started a petition to get the Sptfire's flying times restricted but the locals told them to get stuffed.

Not only that. It's those engineers' deep understanding of classical thermodynamics, which even now gets the job done and involves some pretty meaty math(s)!

My Uncle flew B 25 s in WW2. He was in the thick of it. He came back from one mission. He didn't know until he landed and went to check on his crew. He discovered he was the only one on the plane alive. The the young soldiers were so brave. The metal was so thin. You really had no protection. Thank you to all our brave soldiers who fought and gave there lives for our freedom. Thank you Jay for your great shows. Best to you Dave

Sometimes my appointments at the VA hospital are a blessing in disguise. They take some blood for tests with a urine sample. Standard stuff. But while you are waiting for Meds or the doctor you are sitting right next to older men and women who know what you've been through. I've chatted with men who were waist gunners on B 17's over Germany, Guys on the ground in the Soloman Islands and every conflict since. They have helped me deal with crap 98% of people will never know.

No soldier died for our freedom. Maybe Dutch freedom, Jewish, French, whatever, but Germany and Japan were never a threat to the American continent, and pretending so is pure jingoistic BS.

Thank you for your compliments on Canada and the War effort.

[@bone3013]

It seems Canadians never get much credit, probably because the Americans love taking credit for everything, but good on you mate. Much respect for the Canadians and all great nations who took part in the war effort.

What incredible piece of engineering I’ve been fascinated by the merlin engines for my dad tell me about him in the second world war he was a flight engineer on a B 24 but I saw my first Merlin on a P 51 Mustang just incredible thank you so much for sharing what a beauty I turn my speaker on full blast so I could feel it wonderful

09.27 Lancaster bomber VERA came over to the UK. Amazing sound of 8 Merlins on 2 Aircraft. Back in the 1960's saw these engines being scrapped, such a shame. They are Kings of the V12's. I loved driving a series three XKE with the 5.3L V12. From the first drawning of a merlin I wanted to be a engineer.

I truly love the fact that, no matter how sophisticated or how unusual the vehicle, no matter how incredibly expensive, no matter how old or off-the-showroom-floor, every post is on the subject of what a sincere man Jay is. Gotta love that !

[@jakeroark6718]

That is one of the best sounding most powerful engine's I've seen it was truly stunning and I appreciate and approve of the Merlin 1650. Thanks Jay for letting us see and hear it.

[@wilburfinnigan2142]

The Allison made as much or more HP at sea level !!! Check the specs

[@BryanJohnson4891]

@@wilburfinnigan2142 Depends which Merlin you compare it to… Packard Merlin’s? Maybe. Later war British 2,300 HP ones…. Nope. Plus air combat doesn’t happen around sea level. It happens at 25k ft where a two stage supercharger makes all the difference and the Merlin can perform to its top capability - and where the Allison flops.

@@BryanJohnson4891 Late War BF109 engine was far better got as high as 2800 hp and was super charged and electronically fuel injected and controlled first engine in the world with computerization and built during ww2 under wartime conditions and they built more BF109 than all the other ww2 fighters combined. Its the most produced fighter in history.

[@BryanJohnson4891]

@@pilsplease7561 It wasn’t computerised - that was the FW190, and it certainly wasn’t putting out 2,800 HP - the massively larger expertly designed PW 2800 could just squeeze that with 150 octane fuel. It could get a few hundred HP lower with H2O/Methanol injection, but this was a massive risk to the engine. In practise it never went close to this as it used slide bearings and awful synthetic lubricants. Nowhere near 2800 mate - same displacement as the griffon but worse design and fuel. No replacement for displacement!

[@erikjensen6503]

My dad always talked about how that was the one engine for aviation that certainly win the war. Thank you for sharing it with us!

[@spyintheskyuk]

Well it certainly did indeed win the war simply because without it the war would already have been lost (for Western powers) before it could have been won. Any winner would have been called either Russia or Germany.

Thank you Jay for being this awesome!

"The initial Packard modifications were done on this engine by changing the main bearings from a copper lead alloy to a silver lead combination and featured indium plating. This had been developed by General Motors' Pontiac Division to prevent corrosion which was possible with lubricating oils that were used at that time. The bearing coating also improved break-in and load carrying ability of the surface. British engineering staff assigned to Packard were astonished at the suggestion but after tear down inspections on rigidly tested engines were convinced the new design offered a decided improvement."
