So, just to be clear, your reason is that everyone sucks at driving and thats the reason why not to reduce rotating mass. lol
Crusti, aluminum connecting rods exist, and so do lightweight flywheels and lightweight driveshafts. If those parts didnt work, they wouldnt keep making them for years and years. People would eventually figure it out and stop buying that product.
YOU didnt notice the increase in fuel economy and acceleration because YOU did not have the right logging tools or engine setup. I, with my little data-logger software and my lead foot on the dyno DID notice a difference in fuel economy and acceleration when adding a knife edged crankshaft to an SR20DET for instance.
Just depends on the setup and intended use for the vehicle. Lighter is better in general because rotating mass is an energy hog. Thats all Im saying and its dead accurate.
