TUNING THE ATI
SUPER DAMPER FOR MAXIMUM PERFORMANCE
Extensive dyno and on-track testing has proven the Super Damper
far superior to all other designs, especially on engines that
turn over 5000 rpm.
Our dampers are used on performance and
endurance engines worldwide. Every Sprint Cup, Nationwide
Series, and Camping World Truck engine, and every ASA
LSI Vortec engine. GM’s Vortec off-road 6 cylinders,
the Katech World Challenge C5R Corvettes, and Viper
V10 engines. They all use the ATI Super Damper because
it has proven to be the most effective damper in the
world, thanks to it’s versitily and tunabilty.
To tune the Super Damper on such a wide range of high perfomance
engines, the dampers use seven different inertia weights from
1.2 to 4.5 lbs. Elastomer O-rings in 40, 50, 60, 70, 80, and
90 durometer are available to match a specific inertia weight
to a given engine to eliminate torsional twist of the crankshaft.
ATI’s
Super Damper™ field testing is performed by J.C. Beattie
utilizing Scentific Atlanta’s SA390-2 state-of-the-art Dynamic
Signal Analyzer and SA 250 torsional convertor. Coupled
to a custom designed optical encoder pickup that bolts directly
to the front of the damper, J.C. can read up to twenty orders
of harmonic vibration. He can then adjust inertia weight
and elastomer durometer to reduce specific orders on a given
engine.
By analyzing the torsional crank twist and installing
the correct ATI damper, torsionals can be reduced to 2/10s
of a degree or less.
