i know that lighter flywheel = less torque, so heavier flywheel will = more torque?

 

a heavier flywheel will have more momentum if your say dumping the clutch and the engine will bog down less

 

A lighter flywheel = more torque and less rotating mass

 

Aluminum flywheels are usually for road racing. the lighter rotating mass allows you to accellerate out of corners faster. For a strip car or daily, I'd stay w/ a stock or steel FW to help keep your rpm's up between shifts.
