| 8100 Series Compression Adjuster |
 From
Formula Vee to Indy Car, the 8100 Series adjuster offers a wide range
of compression adjustment for the serious racer. The method in which
the PENSKE 8100 adjusts compression forces is simple. When the damper
is put into a compression condition, the fluid being displaced by
the shaft entering the body must pass through the compression adjuster
drum and the selected orifice located in the remote reservoir. As
the knob is rotated, a drum inside the compression adjuster is rotated,
aligning the chosen orifice within the direct flow of oil into the
remote reservoir. The adjustment knob is numbered, from one to six.
By clicking to the number one position, the adjuster is set at full
soft (utilizing the largest hole in the compression adjuster drum).
The number six position on the knob denotes a full hard setting (oil
flow is greatly restricted). This method of adjusting compression
damping is ideal for most forms of racing, especially those having
higher shaft speeds and displacements. The redesigned orifices make
every adjustment have a noticeable "feel" and have increased
the range of adjustment. At higher shaft velocities, oil passes through
the orifice in the compression adjuster drum and gets a point of "packing-up".
Instead of packing-up and increasing the damping force, a valve in
the compression adjuster housing allows for the oil to bleed off,
making for more linear force curves. |

When the damper is being compressed, the fluid is being displaced into the adjuster and passes through a piston in the adjuster. When making an adjustment, the secondary valve shims are being preloaded, giving you different compression forces. For a minimal investment, the 8660 Series Compression Adjuster may be upgraded to the 8760 Series Compression Adjuster. The addition of a few extra parts will offer you separate adjusters for both high and low shaft velocities. |
When
increased low speed damping control is required, the 8660 Series
Compression Adjuster is ideal. Many teams are looking for a range
of control at low shaft speeds, such as body roll, corner entry
and exit. The design of the 8660 Series Compression Adjuster offers
35% more low speed adjustment than the 8100 Series Compression Adjuster.| 8760 Series Compression Adjuster |

When the damper is being compressed, the fluid is being displaced into the adjuster and passes through a piston in the adjuster. When adjusting the high speed, the secondary valve shims are being preloaded, giving you different compression forces. The low speed adjustment meters the fluid and bypasses the piston in the adjuster, providing an adjustable combination of bleed and shim controlled damping. In effect, the combination of a low speed and high speed adjustments will offer the ultimate tuning combination. |
The
8760 Series compression adjuster is the ultimate tuning tool for
the professional race team. The 8760 Series adjuster offers separate
adjusters for both high and low speed shaft movements. The high
speed adjuster controls larger track inconsistencies that may disrupt
the car, while the low speed adjuster controls slow shaft movements
such as body roll, corner entry and exit.
