ATI Damper Technology
The patented ATI Super Damper® is the only harmonic
damper designed exclusively for high performance engines
yet forgiving enough for everyday drivers. The proven
elastomer design is actually two dampers in one: A 4"
inner diameter and a 5-1/2", 6 3/8", 7",
or 8" diameter outer damper in two shells that
bolt to the crank hub.
ATI Super Dampers® feature a replaceable bolt-in
crank hub. Steel shells are black zinc chromate finished
and Aluminum is Hard Anodized. All have computer controlled,
laser engraved 360° timing marks.
All units are SFI manufacturer
certified and exceed SFI spec. 18-1. The patented Super
Damper® also gives you guaranteed performance. Your
car will run as fast as or faster than with your present
damper or your money back. Dyno tests have proven the
Super Damper® will allow the engine to produce as
much as 45 HP over a poorly sized Fluidampr at 7,500
RPMs and commonly 12 to 30 HP over OEM and other aftermarket
brands on high performance engines.
For years, major manufacturers have used the elastomer-type
damper design. These conventional, single-strip elastomer
dampers have proven very effective on OEM applications
operated at low RPM's. They were also surprisingly effective
at high RPM's. Many engineering studies have shown that
elastomer style dampers to be the far superior to the
friction type and markedly better than the viscous type
in controlling vibrations over a wide range.
Conventional single strip elastomer dampers are not
re-buildable. The main problem with this type of damper
is a loss of certain controls inherent in the manufacturing
process. An inertia weight pressed with a rubber insulator
to the crank hub allows the possibility of the ring
to move in its relation to the keyway. It is also impossible
to maintain the concentricity of the inertia ring during
manufacturing. The ring must be machined after it's
pressed to the hub, and then balanced after machining.
When it works loose with age or from multiple cycles,
the ring will move, and the damper will be out of balance.
Hundreds of these OEM imitation SFI approved dampers
have failed in service on high RPM engines.
Viscous fluid dampers are sealed and you don’t
know you have problem until it’s too late. The
inertia weight can become fixed (locked) by bearing
failure or, more commonly, from the silicone turning
to a solid mass. Your first warning of damper failure
will probably be a broken crankshaft resulting in the
replacement of your damper AND the engine. Viscous fluid
dampers are not only ineffective but are actually detrimental
at high RPM's.
The solution? The ATI Torsional Super Damper®
- the unconventional, unbonded elastomer Super Damper
that is actually 2 dampers in 1 diameter.
The ATI Super Damper® is the only damper designed
exclusively for high performance engines. The proven
elastomer design is actually two dampers in one and
O-ring life has been tested to over 3.5 million race
cycles in Sprint Cup competition (6500+ RPM, 600+ miles)
and 10+ years (188 - 11 run weekends) in drag racing.
The unit is re-buildable to new specifications by installing
new O-rings and field serviceable. You can have a totally
fresh Damper for as little as $75! Extensive dyno and
on-the-track testing by ATI, GM, Toyota Racing Development
(TRD), and all of the NASCAR engine builders have proven
the Super Damper® far superior to all other designs,
and is trusted by 100% of NASCAR engine builders and
reputable engine builders around the world!
