It has been a long time since I last wrote the things I promised in this thread. I have not taken all the measurements I would like yet (corner weights left to do), but I don?t have easy access to such scales. Anyway, will do it soon, as I may have found a solution.
I have however gathered some info, and made some progress with an excel file ? calculator, which is also not finished.
HERE IT IS
First of all, I found some info from the KONI dealership about the yellow shock absorbers, which for some reason they keep it ?confidential?. So here they are:
Part #86-411245 Sport (front) = serviceable
@0,33 m/s -> Rebound = 950N , Bump = 700N
@0,13 m/s -> Rebound = 510N , Bump = 480N
Part # 26-1129 Sport (rear) = NOT serviceable
@0,33 m/s -> Rebound = 2200N , Bump = 1150N
@0,13 m/s -> Rebound = 1050N , Bump = 700N
I feel that these are the maximum values ie when adjusted to the hardest setting. I did ask for clarification, but I got no answer. At least this is a start.
I was also told that these dumpers are not linearly adjusted if you pass the middle setting.
Maybe some of you who followed my project know that I had my old (red) KONIs revalved to yellows. Well, as I found out this was a general assumption, since many kind (numbers ? called 3,5,6 etc) of valves are available and I have no idea which were installed, and generally the red KONIs have different type of manufacturing compared to the yellows. For example a yellow with valve no3 is much stiffer than a red with valve 5!! Also my red, were just oil, while the yellows are gas-oil filled. Reds of this type are no longer available and they were front and rear serviceable, since they had no gas.
Since I intended to use the revalved reds with Ben?s coilover stuff, I had them tested at the dyno, and got some interesting results:
Front ? soft setting ? all left:
@ 50mm/s -> Rebound = -100N , Bump = 261N
@ 100mm/s -> Rebound = -116N, Bump = 452N
@ 150mm/s -> Rebound = -316N, Bump = 581N
Front ? hard setting ? all right:
@ 50mm/s -> Rebound = -268N , Bump = 214N
@ 100mm/s -> Rebound = -379N, Bump = 353N
@ 150mm/s -> Rebound = -467N, Bump = 467N
Rear ? soft setting ? all left:
@ 50mm/s -> Rebound = -471N , Bump = 241N
@ 100mm/s -> Rebound = -709N, Bump = 267N
@ 150mm/s -> Rebound = -837N, Bump = 287N
@ 200mm/s -> Rebound = -960N, Bump = 303N
@ 250mm/s -> Rebound = -1089N, Bump = 312N
Rear ? medium setting ? middle:
@ 50mm/s -> Rebound = -579N, Bump = 184N
@ 100mm/s -> Rebound = -941N, Bump = 223N
@ 150mm/s -> Rebound = -1097N, Bump = 247N
@ 200mm/s -> Rebound = -1275N, Bump = 263N
@ 250mm/s -> Rebound = -1486N, Bump = 275N
Rear ? hard setting ? all right:
@ 50mm/s -> Rebound = -734N, Bump = 160N
@ 100mm/s -> Rebound = -1195N, Bump = 220N
@ 150mm/s -> Rebound = -1378N, Bump = 231N
Also attaching the measurement sheets, just in case I wrote something wrong, or if someone wants to see more details.
FRONT MEASUREMENTS and
REAR MEASUREMENTS
Next step is to complete my excel file with POIK's equations. Hopefully i will have more done soon
