Forged Steel
In racing or street engines, do steel cranks increase power at all?
I know that forged steel crankshafts are stronger. But if one were to replace the cast iron crank with a forged steel crank, would the horsepower and/or torque output of the engine increase at all?
What is a “Knife-edged” steel crank?
If the steel crank is lightweight, does that increase the ability to accelerate faster as well as horsepower and torque?
Knihe edgeing is when the couterweights or other portions of the rotating parts of the crank are ground to a sharp edge and polished so that when/if they cut through the pool of oil in the bottom of the oil pan (during the course of rotation) the oil causes less drag on the crankshaft. I doubt this would add more than a fraction of 1% of hp unless you have a oddly designed oil pan or crank location. And in some engines the oil pan is designed so that the bottom of the crank actually never dips into the pool of oil.
Sport Compact Car magazine had an article written by an automotive engineer who stated that if you decrease rotating mass it is like decreasing the entire weight of the vehicle by 12 times whatever actual weight of rotating mass is removed. So, any lighter crankshaft would increase hp and torque or at least acceleration. Also, a steel crank will be stronger than a cast iron crank and lighter and a forged steel crank would be lighter and stronger beyond that. I think that people go to the forged crank for the increased strength more than the weight decrease. The crank manufacturer would probably have dyno results to prove out increases in hp to give you an exact idea of the impact for your application.
