how come they never made it to the auto world. i would think a radial half moon shape would be good for pushing the engine as far towards the middle of the car possible.

a harley engine is essentially a two cylinder radial engine.

any ideas? schmleff?

I could personally see this being of much bigger use in utility trucks and tractors than in a car.
One of the main benefits to this design seems to be insane torque at very low rpm. That kinda torque wouldnt be of much use in a passenger or performance car.

Radial engines take up waaaay too much space for one thing. They have other issues too that make them impractical. Cant recall the big ones off the top of my head, it's been a while since i studied them in aviation... But there are W engines, that have the top three banks (ie W12). again though, these seem to be problem children of the internal combustion engine familly.

you wouldnt think that they would be to big. smash two harley engines together, narrow angle between the cylinders. im pretty sure some of those harleys can make like 140hp off of two cylinders

They get big because they only have one rod throw. There is a master rod with articulated rods connected to it.

almost all of them are supercharged, and geared.

The use them on pull tractors
