Packard produced its first car in 1899 and would stay around until the late 1950s. 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. assume that this means that the top speed of the Elco at some 41 knots could The three successive versions of these engines were designated as 3M-2500, 4M-2500, and 5M-2500, each of which had slight improvements over the previous version. built PT Boats. "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. Look at the size of those pistons - 6 1/2" diameter. powered by three Packard engines equipped with mufflers to mask their approach, capable of making 40 knots. The engine is equipped with hoist chains and sits in a wood box with castors. This engine WAS for sale, (now sold) it was built on Oct 19, 1943 and 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. Data is a bit sparse on this category of Packard participation, but we know Packards competed on this track too. This is the aircraft version, the marine version was the 3M-2500. By the time Higgins was ready to build the C-46, the faster than expected . The boats were often built by the immortal Gar Wood. The pictures below show earlier versions of the Packard V12 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. It may have been a luxury automaker, but it was clearly operating at a scale that dwarfed Rolls-Royceand it achieved those production figures by embracing mechanized production. a centrifugal supercharger, later models were also fitted with an intercooler. The engineswere dry sump with an external oil tank which had special baffles to reduce foaming. This involved everything from the time-consuming task of redrawing plans for the engines from British third-angle projection to the first-angle projection used in American manufacturing to creating the tooling and jigs needed to assemble them. These modifications have been mentioned by several sources but specifics remain elusive. Packard made a three terminal electrical device to synchronise 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. Spring Carlisle Collector Car Flea Market & Corral, Camp Plymouth Spring Military Vehicle Show & Swap Meet. 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. The Packard Eight was a luxury car built between 1930 and 1936 and was a progression from the earlier Packard Six. 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.. The 4M-2500 is at best, a distant cousin. brake horse power, this had been increased to 1350 BHP 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." 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. There have been many motorsports events in which Packard engines participated, and a high percentage of the time, participated at a high level. 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 . That Packard name. 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. ", Neal also notes that "the British did not specify tolerances and fits, and Packard had to take parts from an existing engine and make measurements to determine these specifications as best as they could, using engineering judgement where necessary.". 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. 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. The engines produced in Detroit went into the P-51 mustang and Canadian built Mosquito fighter/bombers and Lancaster heavy bombers. (i.e., 3A-2500 then 3M-2500). Engineering refinements meant that by the end of the war, the Merlin 66, an intercooled variant of the engine sporting a two-stage, two-speed supercharger, was making 2,050 hp (increased from 1,030 hp in the Merlin II)and these improved engines were allowing aircraft to operate at significantly higher altitudes, as well. The Packard V-12 PT Boat Engine (audio fixed) Les Sharp 3.85K subscribers Subscribe 26K views 9 months ago PHILIPPINES Everyone knows the WW2 PT boat was a rocketship, and that it was. But never fear, Carl Vincent, a chief engineer for Packard, came up with a most innovative solution to the problem when he removed the six cylinders in the right bank of the engine-Merlin and capped them off. been pointed out to me by various people and the historical evidence proves You are not connected to real-time updates. This much power could push the fully loaded boats at 45 to 50 knots. These engines have dual ignition and if the two points were not in exact sync you ended up being the slow poat. To keep things simple there was a clutch or gearbox with just a fixed rearend ratio. 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. far so good! 14. neodymium magnet based crankshaft, 6 sets of coil 'C' cores which fit in the A Chief of Naval Operations (CNO) PT Boat Conference convened in May 1941 to discuss future PT characteristics. However, the basic dimensions remained. shows 6 of the 1/4" Dia x 1/4" long neodymium magnets from www.fieldforce.com The carb on a Packard PT boat engine is about the size of a small milk crate. [citation needed], Data from Aircraft Engine Historical Society[5] and Race With the Wind By Birch Matthews[citation needed]. All contents 2023 The best vintage and classic cars for sale online | Bring a Trailer, Privacy Notice Theres an appealing counterintuitiveness to the notion that a (marginally) sloppier engine makes for a more effective fighter plane powerplant; its a bit like that chestnut about adding armor to the parts of the bombers with no bullet holes. those! 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. I can only imagine Rolls-Royce owners look back on this period of history with equal admiration. the three engines. than the "bumps" on the later mufflers.. [1] Five aero variants were produced, of which the 3A-2500 was the most numerous. This restored motor was apparently going into a PT658 FACT SHEET . looking for someone to restore your PT boat engines, these guy's have the They were subsequently upgraded in stages to 1500-hp (1,150 kW) each, for a designed speed of 41 knots (76 km/h (47 mph)). The engine was donated in 2008 to the seller, the Tahoe Maritime Museum, and is now sold on a bill of sale at no reserve in Carson City, Nevada. grey colour, red looks so much better. I would like to have bought it, only it's in the US and I'm around the So this is the new lower cost engine plan, these two pictures rebuilt at Norfolk in 1959. Did you mean to enter this number as a bid? re-popped Liberty. 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? Rolls-Royce was crafting Swiss watches; Ford was cranking out Timexes. 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. Our car experts choose every product we feature. Ultimately, workers on both sides of the Atlantic were able to build an engine for the ages, flown to victory in all of the major theaters of combat. http://www.hemmings.com/hcc/stories/2006/01/01/hmn_feature17.html. 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. engine "pot" area and other bits and pieces out of Silicon steel Packard built the Rolls-Royce Merlin aero engine under license alongside the 4M-2500, but with the exception of the PT-9 prototype boat brought from England for Elco to examine and copy, the Merlin was never used in PTs. some great detail. Another photo showed a 1916 Packard Twin-Speed 299 car with a V12 engine, possibly a Liberty engine. much compression that he had to back out a set of plugs (these engines have two Robert was kind enough to send me these photo's which show will make up some laser cut laminations and hand wind some better coils but so The engines were fresh water cooled via fairly small tube type heat exchangers, as were the V-drives. bed of the 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. It should be noted that the method of determining the octane rating has changed since that time and the same gasoline , if tested today, would get a lower octane rating, probablyby 5 to 10 points. These engines are 4 stroke, water cooled, 60 degree, V- type with a 6-3/8" bore and 6-1/2" stroke, for a total of 2490 cubic inches of displacement. Detroit's mass-production know-how yielded over 55,000 Merlin V12 aircraft engines during WWII. For some perspective here, note that total Rolls-Royce automobile production from 1936-1939 totaled 6,244 (and that includes 3,824 units of 20/25 production, which spanned 1929-1937; thanks to Mark Lizewskie of the Rolls-Royce Foundation for the information). gearbox which then drove the wing propshafts back down under each engines. 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. Enter Packard. If the part doesnt fit, it is machined until it does meet required specifications. When you bid we pre-authorize your credit card for the service fee (this helps prevent fraud).

All Packard M2500 engines came with cranking motors and DC generators built by the Delco-Remy Division of General Motors in Anderson, IN. And even in those early years, Packard realized the importance of on-the-water motorsports and really supported it. 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. by two spark plugs per cylinder. 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. The final engine version, the Packard 5M-2500, (late 1945) had a larger supercharger, aftercooler, and power output of 1850 hp. Still another Big Car was pictured with the lettering Packard S8, probably indicating a straight-eight engine under the hood. Michelin and BFGoodrich Tires are now Official BaT Partners.

But there is one designation that really had motorsports engine builders panting through the years. This is a 1,500hp (stock) Packard 4M-2500 which was largely based off of the Liberty airplane engine that had been modified for racing boats in the 1920s and 30s. 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. By mid-June 1940, Packard had taken possession of the plans and parts initially given to Ford, and began an ambitious programled by Packard engineering boss Col. Jesse Vincentto tool Detroit up for Merlin production. Fuel consumption of these engines was phenomenal; a PT boat carried 3,000 gallons (11,360 liters) of 100 octane avgas.
