What does a ATI damper do?

In contrast, the ATI Super Damper employs a combination of O-rings and a unique, full-captured inertia ring to dampen harmful crankshaft vibrations. This configuration allows the damper to actually absorb crankshaft harmonics over a wide rpm range.

How do I know if I have an ATI Super Damper?

The Super Damper shell assembly is indexed to the crank hub with an offset hole marked by an indent dimple on the front of the hub and on the front face decal with an arrow. These must be aligned for proper assembly. 2.

What is the difference between a harmonic balancer and a damper?

A harmonic balancer (sometimes called crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly.

Are Fluidampr good?

Fluidampr, a viscous style damper, is among the very highest quality because of its superior durability, effectiveness, and protection across broad frequencies and multiple orders of torsional vibration throughout your rpm range.

Is ATI a fluid damper?

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.

What is a high performance damper?

A common part found on all high-performance engines is a harmonic damper (or harmonic balancer, as they are often called). Found at the front of the engine attached to the snout of the crankshaft, harmonic dampers are used to quell the harmonics of the crankshaft.

How do I choose a damper?

When beginning to size a damper, one needs to first calculate the kinetic energy at impact is generated by the load. This calculation depends upon a number of factors such as mass, impact speed, gravity, whether it’s free moving or driven, translational (linear) or rotational, and stroke of the shock.

Does damper size matter?

As a rule of thumb, the longer the stroke and greater the torque, the larger the diameter and mass. However, larger dampers can affect the acceleration and revving ability of an engine, so the right diameter and mass can help you strike the right balance.

How far should a harmonic balancer go on?

When I tighten down the Harmonic balancer, it goes to about 1/4 inch from flush with the end of the crankshaft. Meaning that the balancer sticks out 1/4 inch past the crankshaft.

Is a bigger harmonic balancer better?

No matter what anybody tells you, size does matter when it comes to the harmonic balancer you use on an engine. Putting an incorrectly-sized balancer on an engine will do more than just cause it to not reach its full performance potential … it will cause serious damage to the rotating assembly.

What size damper do I need?

A simple formula of Width X Height divided by 144 will give you the square footage of a damper. Example: The damper in question is 45 inches X 23 inches using the formula. 45 X 23 = 1035 divided by 144 = 7.1875 square feet of damper area.
