Hello
I was daydreaming earlier today and thought about seeing a funny car in the early 80's with a flat crank in it( 180 *) It sounded like the loudest VW I had ever heard
I do remember Gary Beck using one, but I guess they seemed to die out.....cannot remember any thing else
Does anyone remember them????
take care
Tom

Way back in the day, we are talking the late 40 threw 50s they had what they called a crossfire ford flathead. Thes where the ford 60s small flathead that was used in midgets. They fired 2 cylinders at a time. Was thought they gained torque. I never seen one but was told you needed a different crank, cam and rotor for your mag. There was a lot of mystiqe about them, because it was beyond most peoples tecknolegy. Old guy told me they ain't that much. My mentor said they was a bad breathing small Offy. If you want a 4 cylinder buy one. Made sence to me.

If you ever get a chance look at an old Miller or offy as they became later. they are a work of art. Always amazed me they was invented in 1928 or so and was competitive so long.

I remember the reverse engines with inlets on the exhaust etc...

The 180 crank thing ..


Most of the modern day V8 road (circuit, F1 etc) are 180 cranks.. run as two inline 4's on a common crank.. it possibly has bigger advantages at much higher revs 9 to 14,000

Problem with a flat plane crank is it vibrates a lot, .. now if your looking for power who cares about a bit of vibration.. but for the mainstream manufacturers they wouldnt sell many cars..

Road car even high performance use a 90degree... race car 180...

A british sports car manufacturer made a road car with a flat crank, they shook themselves to bits down the road..
