I caught this on the "Where they Raced" video.
Trying too figure out the physics of how he got more efficiency by this piston setup.

Anyone running one of these?

The pistons don't care where they are, the "efficiency" was it now breathed So much better, it made more power. Because the T block had 4 exhaust ports and only two intake ports this restricted getting more fuel into it.

From a past thread Frank Harris wrote:
"Here is how it came to be. The Model T block has two intake ports. One fires and then two fires. Then four fires and then three fires. The front port flows the mixture fore two power strokes and then the rear port flow for two. Ed Winfield made a crank shaft with the front two flying together and the back two flying together.

The result was a constnat flow with no change of direction. A four port head resolves the issue but he did this when Fords had two intake ports.

So he got a mass improvement in the flat head class and blew away all of his competitors. You have hear about two port Reiley's and four port Reiley's. This is like a four port.

But he got to run in the flat head class. He even beat the twin cam Frontenacs with it on the short tracks.

Suck squeeze bang blow, that's what really makes them go."

Here is the crank:

Thank you for that incredibly informative post, Mr. Wang.

The load path through the crankshaft has fewer reversals in direction which makes for a crankshaft that is less likely to break. Ed Winfield was an incredible genius, so smart that he was nearly impossible to deal with. A very interesting man and a very interesting crankshaft concept.

I would live to build one. Maybe someday. I have a twin brother in Ohio who build race engines. He would be my primary go to guy. The problem is he is so busy. He is "retired" but works every day. He loves flat head engines.

This is quite the idea....
I imagine these cranks are impossible to find?

Is that one yours Jim?

I caught it Jim...
Posted question before I viewed the link you attached.

Russel,
Not my crank, just one posted on this forum.
Jim
