Scripps Model 302 V12 Engine
Saw one in a Hacker this weekend and am curious about the origin of
the engine. It has 2 plugs per cylinder and the layout looks a bit like the Rolls-Royce V12 engines of wwII. Was this engine used in early aircraft-seem to remember Liberty had a V12 engine. Big sucker, 891 cu in and 316 HP. thanks |

There were several other V12s in WWII aircraft and later used in boats.
Packard and Allison come to mind. The Packards were common in WWII PT boats. I think Allison made W16, which had 4 banks of cylinders. I just saw some in an old warehouse that belonged to a retired competition hydro boat builder. Steve s/v Good Intentions |

SHEESH... how many gallons/hr. at cruise speed on that baby? It probably
has never been run for very long at cruise to do an actual calculation beyond a gph meter... Rob * * * "butch burton" wrote in message om...

Steve s/v Good Intentions Allison also made a W24. This was two V12s joined by a common gearbox. No idea what they were used in. There's a picture of one in the book Michigan Madman, by C.J. Potter. He used them (V12 and W24) in pulling tractors. |
Allison W24 (+ Sea Story)
The "W" configuration I mention is in a single block. Kinda like a third of
a radial engine. I'm not sure if it had a single crank shaft. Sea Story: While in the US Navy, I came across an old WWII PC that had "Quad's". This ship was about 100' with twin screw (two shafts) and a total of 8 engines. Power to each shaft was provided by four GMC V8-71s. Two facing forward and two facing aft. Each engine had a twin disc clutch with pnuematic controls and could be engaged/disengaged from the main reduction gear. I came across this ship (actually several), loaded with Cambodian refugees in 1975. The refugees were disembarked by the US Marines and I, with a crew of 8 US Navy sailors, brought this old PC into Subic Bay. Of the 8 engines. Only one engine on the port shaft was operational and 2 engines on the stbd shaft was running. Only operational generator was a 2-71 aux and after about 2 hours it went due to a leaking SW pump spraying onto the 'ole' open face switch board. No power ment no steering system. We took a tow for the last 30 mile to a mooring in Subic Bay. Last I heard, these 'neat' little ships were turned over to Nat. Chineese Navy. Steve s/v Good Intentions |
