Quadruple U

This is my very overengineered Quad U/ Dual W. Its firing order is clockwise in order of rotation then set back one, so out of 8 Cylinders at dead top, 4 are in power stroke, 4 are in exhaust stroke/ intake stroke. So somewhat like a corkscrew motion.

Very fun to listen especially in low RPM. Hard to fit in a decent sized vehicle.

Let me know what you think!
