The Jalopy Journal
The discussion of the Wisconsin mill, and Ralph De Palma is terrific. I did a little casual surfing on De Palma last night, and found that he had...
The thing though is that as successful as this DePalma Mercedes was (including the win at Indy in 1915) it did have a tendency to break. Jim,...
Paul, the original 1650 cubic inch Liberty aero engines made in the teens were of course single cast V 12s. I am not aware though of too many...
Paul as to how much re-engineering they accomplished on DePalma's new motor I do not know. Maybe that information is out there. It may be in my...
as we also know, manufacturers and racers were not above spying to get information. I wonder if there was any coverage of the design in the...
]Paul/David, I believe that is the engine that Anderson drove to a first place at a speed of 102.59 at Sheepshead in October of 1915. This race...
The recent Wisconsin engine talk, not much to add but this valve timing diagram from Dykes Instruction Manual #9, 1918. In spite of what they say...
also check out the flywheel - that has to weigh 150 lbs if it weighs an ounce The 1915 flywheel was 70 lbs. Paul
If anyone has anything to chime in on Burman's motors I certainly would not object. Jim, Merry Christmas! Some good Wisconsin racing...
In the just wondering department, how much do the vintage Indy racers, like a Miller sized car, weigh? Estimated HP? Gary, The 1920's...
I recall reading somewhere that Marc Birkigt of Hisso fame, once made a claim that one of "les Charlatans" stole his idea for the DOHC engine and...
I would wish that someone would do a definitive study on the origins of all of the various valve train successes of the early OHC cars. Borgeson's...
Anyone know anything about the "1914 Chevrolet engine" in this car ..... http://www.nytimes.com/2011/05/29/automobiles/29MULFORD.html?_r=1
Keith, Car 54 what (where) are you ? Any idea what that is ? Looks like a Bugatti Type 55 next door. Paul
Why would Louis Chevrolet have chosen to use a Sterling engine in 1915 in place of an engine he had assisted to develop? Mr Fire, Is there a...
As to who takes credit for the design of the Wisconsin, In 1917 Charles John, the president of Wisconsin gave credit to his chief engineer,...
The Stutz engine designed by Wisconsin in 1916 looks similar to the Frontenac above. Notice the ball bearing crank, single cam, narrow valve...
It seems whenever I try to give anyone credit for OHC valve arrangements during the teens that someone else actually used the same principles on...
I also believe Chuck Davis had some parts and pieces of another one or two Monroe/Frontenacs engines and I believe they are in Speedy Bills...
It looks like the eight, but the exhaust is on the wrong side.
My first thought was his hand was in the air because the engine let go and blew out all that smoke. It is the signal to let other drivers by when...
T-Head, The "influence" of the 1914 GP Mercedes engine on American and British aircraft engines is discussed in T. Suzuki's book "The Romance of...
As to Griffith Borgeson, I like to read his books (and have copies) and they are loaded with great information but I do not always agree with his...
Chuck, It would be great if you could relate the extent of what exactly Miller (and Offenhauser) did in their fix of the Burman Peugeot. Pictures...
Yes, it is missing it's propeller. ALFA was the Italian Darracq factory before 1910, an aircraft engine that never flew. The exhaust valves are...
T-Head, I don't think it is an ALFA, as it did not exist until 1909-1910. The engine looks like a variation of the Riccardo 1906 Dolphin...
Yes, I do. Are those assemblies threaded into the head ? What makes the seal on the bottom ?
I suspect you are right. I am always amazed by the drain pipe diameter exhaust on those 1.5 liter engines. Technically the answer is better...
