Default Re: Cast vs. Steel Crankshaft

The cast crank is lighter which in turn reduces the reciprocating mass of the engine producing more power. The other school of thought is to use a heavier steel crankshaft to keep the rotational momentum of the motor high due to the heavy weight of the car.

Anyone have experience on this subject?
My experience and preference is for a lighter assembly.
The reduction of the reciprocating weight will allow the engine to accelerate quicker.
You can purchase a steel crankshaft that is as light as a cast iron piece.
