(Note: These numbers vary slightly depending on the source.). Packard built over 50,000 Rolls-Royce Merlin aircraft engines before the war was overa stellar achievement given the technology of the day. Both propellers turned the same way, clockwise (right-handed), looking from aft. 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. The Packard Eight was a luxury car built between 1930 and 1936 and was a progression from the earlier Packard Six. Much, but not all of the above information comes from. There is a PT boat with a Packard engine undergoing restoration here in Portland, OR. Basic characteristics. We may earn money from the links on this page.

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. That last factory began churning out engines in mid-1941, but not before Ford, like Packard, overcame a few hurdles. The 4M-2500 is at best, a distant cousin. The detail is amazing, I didn't expect them to come out so well, the rings There are few things better than pulling tractors that use monster vintage engines to put the power to the ground and haul the sled. Something went wrong. However I have another idea which I am also in the "pots". See each listing for international shipping options and costs. 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. 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 boats were often built by the immortal Gar Wood. 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. We are a 501c3 non profit that is in dire need of donations. 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). But it's even tougher to prove conclusively, especially (as Neal notes, regretfully, in Master Motor Builders) given that so many Packard records were destroyed when the company folded. Taking some of those ideas and the basic platform as inspiration, Packard built upon it. looking for someone to restore your PT boat engines, these guy's have the 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. The carb on a Packard PT boat engine is about the size of a small milk crate. The PT Boat Forum & Other World War II Small Combatants / Message Board. commercial ferrite coils (or chokes) for now, just to try out the idea, later I Every part on our car engines has to be interchangeable with the same part on any other engine, and hence all parts have to be made with extreme accuracy, far closer than you use. Thats apparently what this puller did and did so successfully. much compression that he had to back out a set of plugs (these engines have two and a 6.50-inch stroke, which brought it to 2,490 cubic inches. it was rebuilt. In 1927, the Packard Liberty engine was tested again in the Higman Special racecar. 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. See it in all its glory here: All of this seems to back up the claim that Packard went its own way when building the Merlin, at least when it came to tolerances. Powered by three Packard 5M-2500 V12 Gasoline engines rated at 1850 horsepower each! 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. 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. During the early part of the 20th century, there were some Big Cars (now sprint cars) seen with Packard powerplants. The Eight was available on several wheelbases, from 127.5 inches to 145.5 inches. 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. Serial number P3255 is stamped in the crankcase base as pictured above. only be sustained for a relatively short period of time. STA-BIL is designated for 2023 as GRIDLIFEs Official Performance Chemicals and 303 is the events Official Appearance Products line. 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. "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 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. And that meant taking the craftsman out of the equation to whatever extent possibleor in other words, embracing mass production. To keep things simple there was a clutch or gearbox with just a fixed rearend ratio.

Packard modified them for marine use in PTs, hence the "M" designation instead of "A". Senior Packard management report that Jesse Vincent, Packards lead engineer, started on the 3M-2500 experimental engine in 1939 based on converting the Packard 2500 aircraft engine into a marine versionand seven were built for the U.S. Navy. The engine is equipped with hoist chains and sits in a wood box with castors. The photo's below are of an early war Packard engine restored pursuing for a much simpler version. We (engineers) never objected because this blew the carbon out of the engines. the original engines were a boring 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). Remember, Packard, and for that matter, Ford of Britain, were able to jump more or less into mass production of the Merlin, while Rolls-Royce took the engine from a blank sheet of paper to eventual mass production at its three facilities. And sometimes, the occasion calls for a Timex. 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. If so please use the bidding box above. I Instead, Vincent, Packards lead engineer, started with a clean sheet and designed a 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. Hydra-Matic: The First Successful Automatic Trans, The Asna Brand Still Seems Weird Decades Later. Retained equipment includes a Holley downdraft carburetor, centrifugal supercharger, and a Delco-Remy electric starter.

What many are unclear on is exactly what they were, and where they came from. 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)). Packard, you see, was a lot more than just Knudsen's Plan B after Ford rejected the Merlin contract. 1943 Studebaker US Army Flying Fortress Cyclone Engines WWII . So, the Vosper built Motor Torpedo Boats have a direct link to the American Auto Industry. plugs per cylinder, two distributors etc) S/No: 8614. It beggars belief. In the legend of the Merlin, any theorized variation in fit and tolerances cannot be more than a very tiny footnote. original engine. The Packard Marine is a powerful high-speed supercharged, lightweight engine of the aviation type. I'm told that some crews upgraded the engines in the field by changing the The only major revision from the Scott-Paine model was the use of a Packard engine in lieu of one from Rolls Royce.

The license built Merlin engines were not produced by Packard until well into the war years and were of smaller displacement (1670 CID). 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 Merlin II was developed about a year later, and from there it was off to the races: A dizzying number of variants would follow in quick succession. A normal patrol for these boats would last a maximum of 12 hours. Data is a bit sparse on this category of Packard participation, but we know Packards competed on this track too. While Packard had a deal to make the Merlins for airplanes, the engines used in the boats had nothing to do with those. 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. Microfilm Reel provided by Al Ross File: 08Packard_4M-2500-Training Manual.pdf: One of my first idea's was to laser cut all the parts for a 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. 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. Note My intention is to resin But it can be made with the same ease, relatively cheaply, and on a similar assembly line.. pounds, the 4M-2500 had four valves per cylinder, a 6.4:1 compression ratio, and including car engines, of course, and the famous "Liberty" aircraft 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. 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. One of those cars was a 1919 Packard with a straight-six engine, while a 1923 model carried a V12 powerplant, probably a variant of the smaller V12s of the time period.

This may have been in part caused by how they were drained for storage between the wars. P.T. 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. 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. Starting out with an 1100hp rating, it was eventually raised with better performing parts through the war. directly, whereas the port and starboard wing engines faced foward and drove into using for the crankshaft. 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. powered by three Packard engines equipped with mufflers to mask their approach, capable of making 40 knots.
