Ram Automotive Co. has introduced a new range of billet aluminum and billet steel flywheels for V6 Mustangs from 1997 to 2004. The advantage of the billet steel over the original cast iron unit is that, though they weigh the same, around 32 lbs., the billet steel unit is significantly stronger, notes Ram.
Crucially, it remains free of stress cracks and, therefore, safe at high engine speeds and higher clutch clamping forces. In addition, billet steel flywheels operate more effectively with modern high-performance clutch friction materials than do their cast-iron counterparts.
Ram says aluminum flywheels have the decisive advantage of carrying minimal weight. In this case it rids itself of half its mass — tipping the scales at 16 lbs. Lower mass means a lower moment of inertia, which translates to faster response — faster acceleration and deceleration as well as less wheel spin.
