Enter fixed drag force from zeta_backwards_shc.xlsx, which is an averaged fixed value based on many tests |
| |
10-28-19, we changed ca% to equal (ca force / c force) = 15%. Below we have ca force / (c force + ca force) = 13%. But they are both basically the same. |
| |
7-11-21, we changed everything to ca% = 15% for id 14, but not the others

8-23-22 We took id17 (3075) and id19 (3694) and created 4 new incremental targets.
a) id17 (3075) target curve was good, but we had to multiply x 1.27 go get it to align with id19 (3694).
b) We took id17, multiplied cforce by 1.27 and created id22 target, soft.
c) We took id19, changed cforce at 1ips from 32 to 34 and created id21 target, stiff.
d) Then we added those together and divided by 2 to get id22 target, middle.
e) Then we created the 4th stiffer yet target.
f) Then created a softer one.
For drag force we averaged 30 recent dyno tests with LDPB. This drag was used to create c-zeta numbers.
We used actual dynamic gas force for phm bladder kit, i.e. 75
mx18-psh with ressy pist, gas force = 69c, 73d with 16 flsprs
mx18-psh with bladder kit, gas force = 71c, 75d with 16 flsprs
10yzf450-psh with bladder, gas force = 73c, 77d with 16 flsprs
This curve is based on 'prel ring ls' for s50oval
See vdb / excel / zeta_backwards_shc.xlsx for details
Bert says this shock works very well.
