two pistons up at one time, down at one time.
OK, thanks noboD. I thought all four cylinder's were virtually two up two down, but maybe both of the two fires at the same time?, similar to flat single plane V8 crankshaft engine builders are doing for some short track applications?
Here you go(w)-
Thanks Mac! Pete Eastwood took that stuff and built a perfect running replica/tribute/clone. I've said this with other old race car engines, I'd rather see a running car than the engine in a display stand. Bob
My 153. Aren't those happy looking pistons?
Six Ball, Why not add a second distributor and make it fire two simultaneously? That would be a real thumper.
Do the 2U / 2D engines fire two at once? Blowing up the pic of the distributor didn't tell me anything.
Somehow, the sound of Harley V-twins on a single crank pin comes to mind.
The original Winfield " 2 up 2 down " car .
And the Winfield " 2 up 2 down " car today.
It's the original engine in a recreated car .
I built this recreation for Rick Rawlins , here in Calif .
Pete, thank you for bringing Winfield's creation back to life!!!
SOMEday, I would love to carve out a 2 up 2 down crank and have some fun
And if I could spend time with any three people from the past, they would be Ed Winfield, Harry Miller, and John Gerber (in no particular order)
Let's try this: What is the firing order?
1 2 4 3
Flyer, You'd need a new cam to get 'em ready to fire at the same time. I don't how the siamese ports would work and they already shake enough.
ehdubya, What year is that page from?
Thanks for the photos Pete! Recreation, I like the sound of that better. Crazy Chris sure would have loved to see that running. Bob
Here's a not-so-great pic of the camshaft- check out the lobes!
Is there something wrong with that photo? The cam is on the other side of the block. Bob
That looks like it kicked a rod and windowed the block at some point.
Pic may be reversed- don't know about the block getting windowed at all
1911? That is truly impressive. 8 years before a 1919 Essex 4 (178.8 ci) did this. The Essex run is like 6 Indy 500s back to back.
"These cars were noted for their performance and reliability and on the Cincinnati Speedway a racing bodied standard chassis set a world long distance endurance record, in 50 hours covered 3,037 miles, an average speed of 60.7 mph"
Man, I am having such a hard time envisioning how that 2U2D engine works. The pic of the crank shows the 1 and 2 journals are in the same plane. Journals 3 and 4 are in the same plane, but clocked around by what? - 90 or 120 degrees?? So if the firing order is 1-2-4-3 how can that be unless 1 and 2 fired simultaneously? But the pic of the cam lobes clearly shows 1 and 2 are not firing simultaneously. Maybe my question should have been "What is the firing sequence of that engine in terms of degrees of crankshaft rotation?"
A street S74 somewhere in the 30s?
^^^^^^^^^^^^^^^^^ Looking for a photo of this car with the correct size wheels. I think it is an S74 owned by George Waterman at the time of this photo. Here are a few team mate photos. Bob
Bob that is widely believed to be David Bruce-Brown's old car. Plenty of info here https://www.vanderbiltcupraces.com/blog/article/mystery_friday_foto_50_a_historic_race_car
edit; i see i misread your post I'm sorry Bob, What date do you reckon? He must have created quite a stir.
Just back from a Google search, the FIAT that Barney Oldfield drove the former David Bruce Brown car was the one that Brown wrecked and died in. I don't post fatal wreck photos, but it must have been rebuilt for Oldfield to drive. David Bruce Brown in happier days.
Same car now with the proper size wheels & tires. From the 1962 issue of Automobile Quarterly Vol 1 number 1. I remember the day I bought this issue in the Barrett Book Shop in Stamford, Ct. I was eleven years old, it helped shape my interest in the hobby. Bob
