8100
Series
|
From Formula Vee to Indy Car, the 8100 Series double
adjustable dampers are now an industry standard. The
light weight and hand built quality of these dampers
puts them at the top of their class. The 8100 Series
dampers are available in lengths from 10.00"
through 24.00" in 1/2" increments making them
available for most forms of auto racing.
The category, double adjustable, comes from the
fact that the compression and rebound damping is
adjusted externally instead of removing the damper from
the car. The compression adjuster is located on the
remote reservoir. |

The rebound
adjuster is located in the eyelet at the base of the
shaft. The main valving, located inside the damper, may
also be altered in a matter of minutes, by removing the
damper from the car. |

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. |
