And at the center of its story are two great automotive marques, Rolls-Royce and Packard, which built Merlins by the tens of thousands simultaneously on both sides of the Atlantic. I use a harmonic balancer installation tool for big and small block Chevys and just flip it around to mount on my lathe. Were in that kind of situation. I am trying to find out more about how that worked. Packards involvement in boat racing goes back to the early 1920s when the engine of choice was the Model 1237 V12 aero engine with the four numerals indicating its cubic inch displacement. While PT-boats had an option to muffle their engines by routing the exhaust underwater, no such option was on either the 63' or 85' rescue boats, so with straight pipes,stealth operations were not an option on most rescue boats. Whether youre scouring junkyards, ordering cores, investigating factory options, looking at aftermarket cast iron or aluminum blocks, or spending big bucks on billet LS blocks, youve probably noticed its been harder to find exactly what you want for the foundation of your LS build than it historically has. The Packard engine took charge early in 1904 at Daytona, a four-cylinder Packard engine powered a vehicle called the Gray Wolf and covered the five-mile course record of four minutes and 21.6 seconds. Packard built between 12,000 and 14,000 marine engines during the war,depending on the source, three of which went into each of the Navy's 768 PT boats, two astern and one amidships for better service access and the British Vosper MTB's (Motor Torpedo Boats) in addition to the USAAF 85 Air Sea Rescue Boats which used two per boat. The main tube parts are 20mm electrical LS swaps are popular for many reasons, but there are a lot of variations and details to sort through more of them than you may expect and many of them are associated with the intake manifold. There were 1M, 2M, and 3M series marine engines so the 4M, -2500 was not a brand new engine but a new generation engine. The tiny engine produced only 24 horsepower, yet pushed the 1,310 pound two-seater machine to almost 60 mph. On the other hand, I've also read that Packard's cutting-edge manufacturing methods made for Merlins with tighter, more consistent tolerances. Neal and others must be referring to the fit and tolerances of the parts produced, rather than as-installeda distinction that will make more sense as we explore Rolls-Royce's prewar manufacturing methods. Reconnected! It had quickly become evident that the project was going to be more complicated and expensive than planned and Packard lost $300,000.00 (1939 dollars) on the 3M-2500 project. The combined power of the three 27 liter Liberty engines was quoted as 1,500 horsepower from its 36 total cylinders. record holding speed boats of the 1930's and the licence built Merlins were not But there is one designation that really had motorsports engine builders panting through the years. choice with those. other side of the planet, so the freight would have been ridiculous. You're the high bidder. Both built their global reputations as top-level luxury automakers on the strengths of their engineering expertise and high production standards. A number of Ford engineers arrived in Derby, and spent some months examining and familiarizing themselves with the drawings and manufacturing methods. If Im not using torque plates, I tape up both sides and trim out the bores. This page was last updated: 18-Apr 01:01. C-46 Commando: Higgins Aviation was contracted to build 500 Curtiss C-46 Commandos at the aircraft assembly plant in Michoud. What many are unclear on is exactly what they were, and where they came from. But its section on Merlin development, the superchargers of which Hooker played a role in developing, is illuminating: "In my enthusiasm, I considered that Rolls-Royce designs were the ne plus ultra, until the Ford Motor Co. in Britain was invited to manufacture the Merlin in the early days of the War. If the part doesnt fit, it is machined until it does meet required specifications. Packard built over 50,000 Rolls-Royce Merlin aircraft engines before the war was overa stellar achievement given the technology of the day. 4M engine serial numbers range from 701 to 13,400, and the seller states this unit was likely built during the early portion of US involvement in World War II. Rare earth Neodymium magnets are so strong Boats were powered by three 4M-2500 Packard Marine Engines developed by the Packard Motor Car Company specifically for the United States Motor Torpedo Boat program. Thats apparently what this puller did and did so successfully. These modifications have been mentioned by several sources but specifics remain elusive. View cart for details. . Fuel consumption of these engines was phenomenal; a PT boat carried 3,000 gallons (11,360 liters) of 100 octane avgas. Hunt The Frontmulti-car dirt late model team and one of the most successful content creation organizationshas announced a new regional tour called the Hunt the Front Super Dirt Series presented by Sweet Victory Apparel. The BaT Service Fee is 5% of the bid, with a minimum of $250 up to a maximum of $5,000. Lot #37,084. American PT boats served during World War II in the Philippines and the Southwestern Pacific areas, in the English Channel, off Normandy, and in the Mediterranean Sea. This rules. (i.e., 3A-2500 then 3M-2500). re-popped Liberty. 14. only be sustained for a relatively short period of time. But in 1922, the governing American Powerboat Association (APBA) decided to lower the engine displacement to only 625 cubic inches, which was about half that of the 1237 cubes of the Packard 1237 engine. America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft thats 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. However, the basic dimensions remained. Only 15 examples of the 1M, 2M, and 3M versions were built, but 4M production ramped up ahead of the United States entry into World War II, resulting in 12,700 examples being manufactured between 1940 and 1945. Packard made a three terminal electrical device to synchronise Packard was stated as 2400 rpm but note that the Elco This restored motor was apparently going into a The pre and early world war II engines developed some 1200 brake horse power, this had been increased to 1350 BHP and then by the end of the war 1500 BHP, therefore a late war Elco 80' PT had three engines Others, however, like the two-piece block, were actually designed by Rolls-Royce and not yet implemented in production. Is the Florida Climate All That Friendly to Cars? However, there is substantial evidence that three boats in the OSS (forerunner to the C.I.A.) Both of these cannot be true. The pre and early world war II engines developed some 1200 [citation needed], Data from Aircraft Engine Historical Society[5] and Race With the Wind By Birch Matthews[citation needed]. But when it was ready to try a run, it was Indy 500 driver Ray Keech at the wheel turning a scary 207.55 mph. The license built Merlin engines were not produced by Packard until well into the war years and were of smaller displacement (1670 CID).

And a large part of that was Packard's ability to use modern industrial processes to create low-tolerance, highly interchangeable parts. This will make a 12 cycle per revolution motor which the likes of General Electric on superchargers went into the development of the During the early part of the 20th century, there were some Big Cars (now sprint cars) seen with Packard powerplants. Most recently, I was told very matter-of-factly (and by a Brit, if that makes any difference) that Rolls built a more precisely fitted, finely tuned engine that had slightly higher performance potential for a given unit. Courtesy of the National Automotive History Collection, Detroit PublicLibrary, COURTESY OF THE NATIONAL AUTOMOTIVE HISTORY COLLECTION, DETROIT PUBLICLIBRARY. The U.S. Navy used the Packard V-12 Marine Engine (4M-2500) in all U.S. Navy World War II PT boats. As Harvey-Bailey writes in The Merlin in Perspective: "Prior to the War the majority of operations in aero manufacture, build and test had been skilled in both a Trade Union and actual sense. The stock horsepower of the engine was reported as 315 horsepower, but no doubt was probably producing 400 or more in race trim. to align the various sections) and then the right hand picture shows the I would like to have bought it, only it's in the US and I'm around the that all three propellers turned the same way, clockwise looking from aft. directly, whereas the port and starboard wing engines faced foward and drove into Auctions Search Auctions Live Now Premium Like so many historical yarns, the idea that American know-how was able to build a better Merlin (either through greater precision or some degree of calculated, mass-producible impression, depending on whom you ask) than Rolls-Royce is hard to dispel out of hand. Running on gasoline, weighing about 2,900lbs, and using all 12-cylinders to their maximum potential, this mill is one of the neatest we have ever seen in a puller and we have seen a few. But were they better than the ones built in Britain? The Vosper 71-foot Motor Torpedo Boat PT-728 in 2015: In looking at the disposition column in the Tables 2, 3, 4 . There is disagreement among sources as to whether the Packard 4M-2500 marine engine was an updated Packard Liberty engine which was introduced in 1924. It had a gearbox and a chain-drive set-up. And sometimes, the occasion calls for a Timex. A little-known fact is that these engines were produced under license to Rolls-Royce. In the legend of the Merlin, any theorized variation in fit and tolerances cannot be more than a very tiny footnote. Feb 01, 2023Brian LohnesBangShift XL, HISTORIC, RACING & ACTION, Videos, XL Videos0. Tour the worlds only operating authentically restored WW2 Higgins PT Boat PT658 Engine room! The first engines developed 1,200hp, butlater modelswith higher boost levels by the end of World War II made1,500 hp. Your email address will not be published. In any case, Packard's version of the Merlin XX, which the Detroit automaker dubbed the V-1650-1, was ready to run by August 1941. Following the attack on Pearl Harbor in December 1941, and the United States' declaration of war on the Axis powers, civilian automobile production quickly ceased; by early 1942, Packard was free to focus all of its effort on military engine production. Did you mean to enter this number as a bid? Blueprinted, handmade and expertly tuned Merlins might have been nice to have under ideal circumstances, but WWII demanded materiel in almost unfathomable quantities. This Packard 4M-2500 engine is one of approximately 12,700 built and is believed to have powered a US Navy patrol torpedo (PT) boat during World War II. The 3A-2500 was an improved version of the 2A engine used on the Huff-Daland XB-1 Liberty bomber of World War I vintage. Here was an incredibly complex piece of machinery, conceived before the clouds of World War II gathered and continuously refined in the pressure cooker of combat, that would go on to power some of the most unforgettable piston-driven warplanes ever designedthe Supermarine Spitfire and the P-51 Mustang among them. The mistake here, and the foundation of the file-to-fit Rolls-Royce Merlin idea, is likely in conflating early engines, which were built in relatively limited quantities throughout the early to mid-1930s, with the mighty (and mightily improved) mass-produced Merlins that emerged as the war progressed. The Liberty engine showed strong again about a decade later, only in this case, on the White Triplex Special, there were three Libertys installed two side-by-side in the rear and one centered in front of them. Robert says he has drawings somewhere! document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Please enable JavaScript to engage in the discussion on this site. Packards early efforts resulted in the successful Liberty V12, which arrived several months after the United States April 1917 entry into World War I. Rolls-Royce began producing its Eagle V12 in early 1915, also to power warplanes; it started development of the PV-12, the engine that would become the Merlin, in the early 1930s and had running prototypes by 1933. PT658 FACT SHEET . BaT MOTO Alumni Gathering: May 6 at The Quail in Carmel, CARegistration is Open! The Packard Motor Co. is best known for its "super-luxury" cars. Lot #35,238. Packard built many thousands of engines prior to the second world war The first "production" version of the engine was the Merlin I, which arrived in 1936, but fewer than 200 examples were built. improved versions with higher boost levels nominally made 1,500hp. So this is the new lower cost engine plan, these two pictures The early engines required 91 octane gas, but the early W7-W8models were up to 100 octane and toward the end of production,serveral Korean War veteransstate thatthe model W14 required 115/135 octane (green avgas), although the Operators Manual, located in the Manuals & Publicationssection does not specify anything higher than 100 octane. ', "I replied loftily, 'I suppose that is because the drawing tolerances are too difficult for you, and you can't achieve the accuracy. Packard Automotive would supply engines to power Allied planes and maritime vessels, including the British Royal Air-force and U.S. PT Boats. So, the Vosper built Motor Torpedo Boats have a direct link to the American Auto Industry. However, at top speed, consumption increased to 166 gallons (628 l) per hour per engine (or 500 gallons per hour for all 3 engines). The 4M-2500 was the fourth marine variant, succeeding the 900 horsepower 1M-2500, 1,000 horsepower 2M-2500, and the 3M-2500, which debuted in 1939. (Opt Out of Sale/Targeted Ads). The right hand picture Packard built between 12,000 and 14,000 marine engines during the war,depending on the source, three of which went into each of the Navy's 768 PT boats, two astern and one amidships for better service access and the British Vosper MTB's (Motor Torpedo Boats) in addition to the USAAF 85' Air Sea Rescue Boats which used two per boat. Retained equipment includes a Holley downdraft carburetor, centrifugal supercharger, and a Delco-Remy electric starter. The tiny engine produced only 24 horsepower, yet pushed the 1,310 pound two-seater machine to almost 60 mph. Rolls-Royce did even better at 82,117 (32,377 at Derby, 26,065 at Crewe and 23,675 at Glasgow), and Ford of Britain ultimately built 30,428 at its Manchester facility. Required fields are marked *. rebuilt at Norfolk in 1959. had heavily modified the engines in P-563, P-564 and P-565 to achieve speeds of about 55 mph and added a muffling sytem for low speed stealth operations. I can only imagine Rolls-Royce owners look back on this period of history with equal admiration. . When it came time to build the V-1650, Packard was in an almost indisputably better place to build it in quantity than Rolls-Royce was when it began developing the Merlin in the early to mid-1930s. But it can be made with the same ease, relatively cheaply, and on a similar assembly line.. This is the aircraft version, the marine version was the 3M-2500. There are few things better than pulling tractors that use monster vintage engines to put the power to the ground and haul the sled. Elco 80' PT Boat Specifications Updates 2010 September 14 update: Packard engine data added. The motor end pieces shown above were cut out of 1/16" In twin-screw installations the ideal arrangement is to have the tops of the propeller blades turning outward for better maneuvering qualities but this was not available with the Packard engines in the 85s which made docking a bit more challenging as it was almost impossible to get the stern to move to starboard. You are not connected to real-time updates. Hydra-Matic: The First Successful Automatic Trans, The Asna Brand Still Seems Weird Decades Later. Attempting to connect. The two engines face aft, through Joes Gear transmissions, each drive shaft connectinginto a Watson and Flagg V-drive which then drove the prop shafts back under each engine. Harvey-Bailey's assessment seems to reflect the consensus: "At Squadron level there were times when there were fortuitous variations in reliability either way but when dealing with large numbers of engines at Group or Command level there was good consistency in results between British and Packard engines. powered by three Packard engines equipped with mufflers to mask their approach, capable of making 40 knots. Another photo showed a 1916 Packard Twin-Speed 299 car with a V12 engine, possibly a Liberty engine. Something went wrong. In early 1941 the U.S. Navy Bureau of Ships (BuShips) lent Packard engines to both Huckins and Higgins, which wanted to build competitive boats at their own expense. Here's the web site You may want to contact them for information. By the time Higgins was ready to build the C-46, the faster than expected . In twin-screw installations the ideal arrangement is to have the tops of the propeller blades turning outward for better maneuvering qualities but this was not available with the Packard engines in the 85s which made docking a bit more challenging as it was almost impossible to get the stern to move to starboard. It is not in running condition and sits in a wooden box equipped with castors.

The Martelli Brothers, organizers of the BFGoodrich Tires Mint 400 in Las Vegas and the California 300, have acquired the historic Parker 400 off-road racing series. produced by Packard until well into the war years. Packard, by contrast, built one that was ultimately easier to construct consistently and overhaul at specified intervalsand that one of the ways Packard accomplished this was by building Merlins with looser tolerances than its counterpart on the other side of the Atlantic. I get much less oil in the spray washer this way. The 4M-2500 is at best, a distant cousin. The first engines developed 1,200hp, butlater modelswith higher boost levels by the end of World War II made1,500 hp.

Basic characteristics. You get the idea! looking for someone to restore your PT boat engines, these guy's have the Packard also needed to figure out how to obtain (or create) fasteners that used British thread standardssome of which had been further modified by Rolls-Royce to meet specific needs. All U.S. PT boats were powered by three 12-cylinder gasoline-fueled engines. FrozenMerc, Nov 11, 2011. Starting out with an 1100hp rating, it was eventually raised with better performing parts through the war. Detroit's mass-production know-how yielded over 55,000 Merlin V12 aircraft engines during WWII. However, using the older 4M-2500 engines, increases in the weight of the boats due to more weaponry offset the potential increase in top speed. Rolls-Royce was crafting Swiss watches; Ford was cranking out Timexes. . We were all a bunch of 20 year old kids and pushing too hard in fairly rough water could bounce the boat out of the water hence the overspeed cutout. On the surface, its conceivable that two pretty good Detroit-built Merlins were worth one exquisite Merlin handcrafted in Crewe.
