Aluminium Flywheels

, ok , underpowered cars won't benefit from a lighter flywheel? way back before most you were born, the trick back then was in a model A ford, was to lighten the flywheel. instant gain in acceleration. you could outrun any other model A on the street. I know, its not with todays cars. I run light flywheel, 12# in my duster, I launch at 4400 to 5000 on the mat, car wheelstands and doesn't bog. this is a 340 low comp motor.
