FACT: harmonics CAN destroy these motors despite their ideal
'inline six' balance. Popular word on the street says the OEM units
do not fail, but we have dozens of clients who prove otherwise.
Some racers would bring a few spare units to each event -not any
more. Simply fitting their engines with the VAC damper solved their
issue and restored confidence in the powertrain.
ATI Performance Products, a leader in harmonic dampers has
developed a VAC exclusive damper for the S54 engine.
These VAC exclusive dampers eliminate nearly all unstable
crankshaft harmonic vibration which allows the engine to produce
more horsepower and torque, maintain reliability and ensure
internal engine wear in minimized.
When used with our included VAC Pulley, this is a direct bolt on
solution. Available in overdrive, underdrive (for use with standard
size pulleys) or standard diameter (for use with under driven
accessories, or supercharged cars). Also, configurations available
for use with our dry sump kits. This damper has a 7" outer
diameter and it includes OEM style timing alignment tabs.
