A BRIEF HISTORY AND DISCLAIMERS
FIRST DISCLAIMER I don't know what I'm talking about.
Both the fork and shock can be dyno tested. - There are two different types of dyno tests.  We refer to them as: Dyno load cell test: where the load cell records the overall compression and rebound forces from the shock. Pressure test: Pressure sensors are added to the shock body recording pressures in the three chambers. P.c . . . pressure in the compression chamber (comp). P.r . . . pressure in the rebound chamber (reb). P.ca . . pressure in the compression adjuster chamber (cadj). P.gas .  pressure in the reservoir, which is the same as P.ca, so we don't record P.gas.
In 2006 we acquired a dyno and started running tests. The test results were not what we expected, so we decided to document these discoveries. - From 2006 - 2013 we ran the dyno load cell tests. Any documentation in that time frame is limited to our experience with load cell results. From 2013 - present we run both dyno load cell and pressure tests. Documentation from 2013-on is more precise and includes pressure test experience.  We had found that incorrect assumptions were made with the load cell tests because we didn't have a breakdown of the forces.  - Pressure testing breaks down the forces into their four main parts: comp force from the main piston cadj force from the cadj piston gas force from the nitrogen charge drag force from the shaft seal, bushing and piston band
SECOND DISCLAIMER With hands-on experience we thought we knew what we were talking about, then learned we didn't. With dyno experience we thought we knew what we were talking about, and found out we didn't. Now with press testing experience we think we know what we're talking about, but probably don't. HENCE THE DISCLAIMER We don't know what we're talking about.
