V6 Mustang Billet Flywheels
Billet Aluminum and Steel Replacements for Cast Iron Originals Offer Numerous Advantages
Ram 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 32lbs, the
billet steel unit is significantly stronger. 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.
In comparison, the aluminum flywheel has the
decisive advantage of carrying minimal weight. In this case it rids itself of
half its mass—tipping the scales at 16lbs. Lower mass means a lower moment of
inertia, which translates to faster response—faster acceleration and deceleration
as well as less wheel spin.
Constructed from 6061-T6, Ram’s aluminum
flywheels use 1/4in thick steel inserts to avoid distortion. To maintain their flatness the inserts, which
mate with the clutch disc friction surfaces, are fastened to the flywheels by
18 rivets.
To overcome clutch snatch or chatter and
provide minimal run-out, these new flywheels are Blanchard-ground, contributing
a proper friction surface. It also ensures the flywheel is parallel to the
mounting flange. In addition, Ram counter-bores the flywheels for button-head
cap screws that secure the starter gear ring to the flywheel. Ram’s
new flywheels replace the original cast iron units on all 3.8 liter V6 Mustang
models of the following years: 1997-1998; ’99-’00; and both 3.8 and 3.9 liter
models 2001-2004. The flywheels on model years from 1997 to 2000 are externally
balanced; the later units from 2001- ’04 have zero balance. All flywheels are
fitted with 164-tooth starter gear rings.
- Billet
steel flywheels are stronger than cast iron and safer at high rpm
- They
also function better than cast iron when used with modern friction
materials
- Billet
aluminum flywheels are light: they accelerate and decelerate faster
- Blanchard-ground
flywheels are free of clutch snatch, chatter, and run-out
- Blanchard
grinding ensures the flywheel is mounted parallel to the crank flange
- Billet
aluminum flywheels with robust 1/4in steel inserts avoid distortion
