Smaller SC pulleys and or larger crank pulleys with PSKs would be the worse condition for this obviously.
The dog bone springs in the SC pulley would be under greater stress and lead to earlier failure.
All interesting points Dave; I'm not certain. I didn't have any belt slip before
or after the mod.'s. I've been scratching my head over this for awhile now. The surge is definitely the SC clutch "hooking", and happens at precisely the same rpm. Here is my theory: With the added torque and horsepower from the modifications, the engine works easier, and it's harder to reach the 44% "load" threshold that our AMG power plant was originally programed with to engage the SC. Thus, it will reach the "2900rpm" threshold before it reaches the "load" threshold.
Does anyone else with highly modified SRT6 experience this? I've got big air
and big fuel.
