"With the development of the new factories, men and women had to be trained to make and repair aero engines in areas where the skills were not endemic. Both built their global. The tiny engine produced only 24 horsepower, yet pushed the 1,310 pound two-seater machine to almost 60 mph. experience! Since Autoweek is talking tolerance this week, it seemed like an opportune time to dig a little deeper into the Merlin storywhich, after all, is a big point of pride for Packard car owners like myself. Your email address will not be published. The supercharger was toward the stern and the gear shifter toward the bow. To keep things simple there was a clutch or gearbox with just a fixed rearend ratio. The main tube parts are 20mm electrical 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 consumption rate for each engine at a cruising speed of 23 knots was about 66 gallons (250 l) per hour (200 gallons per hour for all 3 engines). And sometimes, the occasion calls for a Timex. "PT Boats were powered by three V-12 supercharged engines," remarks Roger Luksik, member of the Packard Motor Car Foundation's Board of Trustees. The pictures below show earlier versions of the Packard V12 The photo's below are of an early war Packard engine restored Contrary to some sources, the Packard V12 4M-2500 marine engine did not start its life as a copy of the British Rolls Royce Merlin engine. Powered by three Packard 5M-2500 V12 Gasoline engines rated at 1850 horsepower each! 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. Melbourne using an Epilog Mini 50 watt CO2 desktop laser cutter, I want one of the original engines were a boring The modelling objective here is to make an operational 1/20th scale Here's the web site You may want to contact them for information. The first "production" version of the engine was the Merlin I, which arrived in 1936, but fewer than 200 examples were built. Atlantic Cruising Club's Guide to Florida's West Coast Marinas - Book with b Leave feedback about your eBay search experience - opens in new window or tab. It beggars belief. 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. Weighing 2,900 Its best effort was a 171.02 mph clocking at the Brooklands Road Course in England. Also please see our website at www.savetheptboatinc.com. "dashboard" tachometers show a top speed of 3000 rpm. The PT Boat Forum & Other World War II Small Combatants / Message Board. And to give a sense of how thoroughly this largely parallel, if somewhat staggered, transatlantic development effort has clouded the record, Neal states that Packard modified the design two-piece block to better facilitate production; when Rolls-Royce eventually implemented a slightly different two-part block, Packard subsequently adopted the Rolls-Royce design. A Holley 1685FR downdraft carburetor, crank-driven centrifugal supercharger, and Delco-Remy 841 electric starter motor are retained. adding armor to the parts of the bombers with, third-angle projection to the first-angle projection, The Packard Merlin: How Detroit Mass-Produced Britains Hand-Built Powerhouse. From this modern vantage point, it might seem inevitable that Rolls-Royce would join forces with Packard to produce Merlins. The supercharged 41-liter V12 produced 1,200 horsepower when new and features overhead camshafts and four valves per cylinder. As WWII approached, both companies had extensive experience with aircraft engines under their respective belts. . Missed updates will be sent once your connection has been reestablished. Please help! I've uploaded a fixed version here: https://youtu.be/Y3leTYmAiWMOr you can use the subtitles.Everyone knows the WW2 PT boat was a rocketship, and that it was powered with big, beefy engines. 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. Get A Closer Look At The Detroit Speed-Built 1965 Buick Riviera Gran Sport, Watch This Pulling Tractor That Uses A WWII Packard PT Boat Engine Drag The Sled All The Way Home. 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. I am trying to find out more about how that worked. Does the Clock in Your Old Car Actually Work? Dump some 100 octant gas in it, let it get warm, and then give it hell! There were 1M, 2M, and 3M series marine engines so the 4M, -2500 was not a brand new engine but a new generation engine. So, the Vosper built Motor Torpedo Boats have a direct link to the American Auto Industry. These modifications have been mentioned by several sources but specifics remain elusive. Taking some of those ideas and the basic platform as inspiration, Packard built upon it. A number of Ford engineers arrived in Derby, and spent some months examining and familiarizing themselves with the drawings and manufacturing methods. Apparently this engine is now going into a Hackercraft. . document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); We are always looking for good bang shifty stories, projects, photos & videos. Find them Robert. See each listing for international shipping options and costs. It probably helped that America was not at war when ground was broken for itand anyway, the threat of Axis bombers flying to the Midwest to flatten it was somewhat less than the chances of the Luftwaffe raining fire on the manufacturing plants of the Midlands. These beasts will propel the 50 ton boat at speeds up to 50 knots. I am obviously not the first person to compare British and American-built Rolls-Royce Merlin engines; over the course of writing this survey, I found several other articles that covered similar territory and add further insight. Robert was kind enough to send me these photo's which show However, the basic dimensions remained. You get the idea! Driven by Indy Car star Ralph DePalma at the Daytona Measured Mile, a new record was established at 149.875 mph. New to Buying Tools? 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. But were they better than the ones built in Britain? STA-BIL is designated for 2023 as GRIDLIFEs Official Performance Chemicals and 303 is the events Official Appearance Products line. neodymium magnet based crankshaft, 6 sets of coil 'C' cores which fit in the DAA Industry Opt Out It conjures up thoughts of the rich, the famous, long limos along with the brands perfectly molded fenders and hoods. A Chief of Naval Operations (CNO) PT Boat Conference convened in May 1941 to discuss future PT characteristics. Packard was stated as 2400 rpm but note that the Elco 1943 Packard Engine Precision Built Power PT Boats Mosquito WWII Era Print Ad. The war was over, and the shortage of Packard engines for the PT boats never materialized. and then by the end of the war 1500 BHP, therefore a late war Elco 80' PT had three engines However, at top speed, consumption increased to 166 gallons (628 l) per hour per engine (or 500 gallons per hour for all 3 engines). magnets in 60 degree staggered sets of 4 and 12 electromagnet coils will be up Introduced at the New York Auto Show in January of 1932, the classic Packard V12 was an all-new engine, but it did have a historical precedent with the company. Packard had investigated the prospect of building Merlins under license as early as 1938. Navy's 768 PT boats, two astern and one amidships for better service access. This rules. Required fields are marked *. 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. Rolls-Royce Limited was established in 1904; the Packard Motor Car Co. was founded in Warren, Ohio, a few years earlier, in 1899, and set up shop in Detroit in 1903. There are many variations on this basic storyline, more than a few of which are contradictory. The engines were fresh water cooled via fairly small tube type heat exchangers, as were the V-drives. At the end of World War II, there was great availability of surplus equipment at unbelievable prices. 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. Bad ass. Number of bids and bid amounts may be slightly out of date. If there's any truth underlying the mythos, it's likely to be in the somewhat incongruous comparison of the early Rolls-Royce Merlins and later mass-produced American Merlinsand it would still hold true if you stacked the earlier engines up against those Rolls-Royce itself would construct in great quantities once it began employing unskilled labor and modern production methods. Reconnected! Rolls-Royce was crafting Swiss watches; Ford was cranking out Timexes. Packard built many thousands of engines prior to the second world war In this case we are talking about a tractor using a WWII Packard PT boat engine to drag the sled all the way home. With an aluminum block with steel cylinder sleeves and weighing in at 2,900 pounds, the engine had a 6.4:1 compression ratio, and a centrifugal supercharger; later models were also fitted with an intercooler. This was sort of a race and the slower boat would get the lead boats rooster tail whipped over his bow and a resulting bath. Under the Operators Manuals button you will find a PT Boat Engineers Handbook; essentially a Packard Manual without pictures. It would suck down 474 gallons of fuel an hour and propel a PT boat to the blazing speed of 40 knots while working with another identical engine. Today, modern engine builders are building more Merlin horsepower with Allison V-1710 engines, connecting rods and replacement of the intercooler with an ADI injection system (half alcohol and half distilled water). rebuilt at Norfolk in 1959.

Each engine has 48 valves, 2 inlet/2 outlet per cylinder. Owing to variations in development programs, the varied aircraft they powered and the different mission profiles they fulfilled, it is difficult to compare Packard and British-built Merlins directly to determine if one was in fact "better." Their aircraft roots gave them many features of aircraft engines, such as superchargers, intercoolers, dual magnetos, two spark plugs per cylinder, and so on. I am intending to use some Packard produced a number of remarkable V12 engines through the years, including this one: the silky Packard Twelve of the Classic era. This engine was used for both the 85 ft. crash boat, the more common PT-boats and The British Power Boat Co. high speed rescue launches . built PT 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. 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. Propulsion. shows 6 of the 1/4" Dia x 1/4" long neodymium magnets from www.fieldforce.com by J and M Machine Co of Southborough, MA, USA, http://www.jandm-machine.com The centre engine faced aft and drove the centre prop shaft The 4M-2500s initially generated 1200 hp (895 kW) each, together roughly the same power as a Boeing B-17 bomber. Copyright 2023 BangShift LLC. electric motor (and possibly gearbox) housed in a cast shell and when completed it should fit the exact mounting The following specifications were derived from Elco drawings, the Navy build manual, reference books, and the net. Data is a bit sparse on this category of Packard participation, but we know Packards competed on this track too. The engine and ancillaries are finished in gray paint, which is peeling throughout. 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. did not start it's life as a 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. 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. Michelin and BFGoodrich Tires are now Official BaT Partners. 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. According to the owner Robert A Stadler, it only ran for 5 minutes since Makes for a pissed off skipper and we would be down working on very hot engines the minute we tied up. 1939). Redline was 2,400 rpm and it was OK to run the thing at 2,000 RPM sustained on the water. 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. directly, whereas the port and starboard wing engines faced foward and drove into bearings into the end pieces as the crankshaft bearings. 14. A number of famous boats of that era used the powerplant including the Packard Chriscraft II and III boats and the Miss Packard, which competed in a number of unlimited races such as the 150-mile International Sweepstakes race. conduit and a couple of fittings glued together. Another photo showed a 1916 Packard Twin-Speed 299 car with a V12 engine, possibly a Liberty engine. In the end, the mass-produced Ford & Packard upgrades resulted in the Merlin becoming a very dependable engine with longer service and rebuild intervals than the R-R designed and craft-produced engines. Spring Carlisle Collector Car Flea Market & Corral, Camp Plymouth Spring Military Vehicle Show & Swap Meet. A Rolls-Royce did not manage its incredible overall production numbersagain, greater than those achieved by Packard, albeit at multiple plantsby adhering to its prewar manufacturing methods: It did so by mechanizing. Navy acceptance trials for every boat required it be able to demonstrate ability to achieve design speed of 41+ knots. The supercharger was toward the stern and the gear shifter toward the bow. these photo's were sent to me by John and Michael of J and M. So if you are all the clockwork. shatter. are only 1mm wide and I must say from past experience I expected them to burn Exactly, PT Boats used 3x 2500 series Packard V-12's rated from 1200 to 1850 HP. improved versions with higher boost levels nominally made 1,500hp. I have not looked at the layout of the PTs but the difference in the number of engines may be due to the need to allow space for the dispensary with eight litters in the stern of the crash boats, or due to the additional weight of the torpedoes. using for the crankshaft. much compression that he had to back out a set of plugs (these engines have two We can have substantial parts of the population committing suicide, and still run and look fairly good.Thomas McGuane (b. Union rules and demarcations had to be eased by dilution agreements, and such were the aptitudes of the British that all over the country the so called butchers, bakers and candlestick makers and their wives and girl friends increased the trickle of engines to a river of power.". Packard Automotive would supply engines to power Allied planes and maritime vessels, including the British Royal Air-force and U.S. PT Boats. A conveyor belt brings the engine to the parts which always fit for by American methods all parts are made so precisely that they are always interchangeable.. at 2400rpm, some source state 1,800 hp.but that was the emergency rating at 2800rpm according to Packard documents. Much, but not all of the above information comes from http://www.PT-Boat.comand Packard documents on their website. The stock horsepower of the engine was reported as 315 horsepower, but no doubt was probably producing 400 or more in race trim. Before and after shots showing the supercharger impeller and 2010 March 1 update: Added camber information, and fuel tank capacity corrected. [citation needed], Data from Aircraft Engine Historical Society[5] and Race With the Wind By Birch Matthews[citation needed]. Blueprinted, handmade and expertly tuned Merlins might have been nice to have under ideal circumstances, but WWII demanded materiel in almost unfathomable quantities. This content is imported from YouTube. 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. 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. Both propellers turned the same way, clockwise (right-handed), looking from aft. carbking Members 4.2k Author Posted November 29, 2007 Thank you, question answered.

Basic characteristics. Packard V12 Marine Engine that looks like the original V12 engine but is actually an The right hand picture The engine continued to bea four-stroke, 60-degree V-12 with a6.40-inch boreand a 6.50-inch stroke, which brought it to 2,490 cubic inches,with four valves per cylinder. Three marine versions, used most prominently in American World War II PT-boats, the 3M-2500, 4M-2500, and 5M-2500, were also derived from it. choice with those. While some people will say that the PT boats used Merlin engines, they would be wrong. (i.e., 3A-2500 then 3M-2500). Some of these improvements were developed by Packard engineers in an effort to make the complex engine easier and quicker to build in quantity. Bid for the chance to own a 1920s Packard V12 Marine Engine at auction with Bring a Trailer, the home of the best vintage and classic cars online. To see excellant cut-away photos of the Packard engine click here and scroll about one third down the page. It did feature a number of improvements over the British-built Merlins, such as a two-piece cylinder block. 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. The Eight was available on several wheelbases, from 127.5 inches to 145.5 inches. The received wisdom, at least in America, usually runs along the lines of: If Rolls-Royce birthed a stupendous engine, Packard brought American mass-manufacturing know-how to the equation, perfecting the design and mechanizing production. A normal patrol for these boats would last a maximum of 12 hours. In 1927, the Packard Liberty engine was tested again in the Higman Special racecar. In this video we go through the development history of the Packard M-2500 series of engines, and common misconceptions as to what they were.No monkeys were harmed in the making of this video.Chapters0:00 Start1:53 Liberty L12 engine4:33 Packard 1A-25008:00 Packard 1M-2500 marine engineSincere thanks to Randy 'Motor Mac' Smith for the video clip of a 4M engine starting up. Bidding will advance immediately to $. Though these initial discussions went nowhere, the British declaration of war on Germany in September 1939 meant that a new manufacturing partner was urgently needed. That is the only way we can achieve mass production.'". at 2400rpm, some source state 1,800 hp.but that was the emergency rating at 2800rpm according to Packard documents. There is a PT boat with a Packard engine undergoing restoration here in Portland, OR. We need more information about your vehicle to confirm fit. Fuel consumption of these engines was phenomenal; a PT boat carried 3,000 gallons (11,360 liters) of 100 octane avgas. It had a gearbox and a chain-drive set-up. We'll give you credit for the submission (of course) and what is cooler than showing all your gang that you have a story on Bang Shift? produced by Packard until well into the war years. If you want to dive into the minutiae of Merlin development, it's worth grabbing a copy of The Merlin in PerspectiveThe Combat Years, by Alec Harvey-Bailey; there's simply too much info to relate it all here. 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. The U.S. Navy subsequently awarded a contract to Elco on December 7 for 11 motor torpedo boats and 12 motor boat submarine chasers. by two spark plugs per cylinder. All of a sudden, we had a 617 cubic inch engine, eight cubes less than that specified by the new rule. It was a legacy of its World War One job of building the famous Liberty engine. PT658 Detailed Fact Sheet. [1] Five aero variants were produced, of which the 3A-2500 was the most numerous. As mentioned earlier, 85 ASRs also had two Chrysler 6 cylinder cruising engines in the original design, others say they were Kermath marine conversions of 110 hp Ford V-8s, although very few were actually built,which may have taken the space of the third Packard engine installed on the PT boats. 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. Thanks Jerry . assume that this means that the top speed of the Elco at some 41 knots could The audio on this one is mangled. 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. By the time Higgins was ready to build the C-46, the faster than expected . Stanley Hooker's autobiography, Not Much of an Engineer, deals mostly with his work on Rolls-Royce jet engines. This notion is also reflected in the March 1946 issue of Flying magazine, which includes a retrospective on the powerplant by Paul H. Becker titled Mass Producing the Merlin: It took the war to prove that the aircraft engine is not that complicated micro-micro-inch construction problem peacetime talk has made. Packard built over 50,000 Rolls-Royce Merlin aircraft engines before the war was overa stellar achievement given the technology of the day. After the challenges were overcome, they had redesigned the engine patterns,upgraded the quality control and metallurgy standards and made many major changes that involved extensive redesign. This is perhaps where historians like Neal acquired the notion that Rolls-Royce did not supply tolerances for Merlin component production; small batches of parts and pieces could have, conceivably, been fettled to meet specified tolerances by skilled laborers on the bench before assembly, at least in the early days. Terms of Use, Your Privacy Choices The Packard 1A-2500 is an American V-12 liquid-cooled aircraft engine designed by Packard in 1924 as a successor to the World War I-era Liberty L-12.

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. 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. Attempting to connect. 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. It is not in running condition and sits in a wooden box equipped with castors. 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. This is the aircraft version, the marine version was the 3M-2500. These were serial numbers 43-43339 through 43-43338.
