On my Six Pack I'm currently running the purple springs in the secondary diaphragms, was running the light yellow springs before. Since switching to the purples at times while accelerating I can feel a sudden kick in my pants as the car surges forward. Could this be the secondaries suddenly opening up more, or could it be from the clutch fan shutting down?
What springs is everyone else running in the secondaries? And would a stiffer spring make the sudden acceleration surge even more noticeable? I know I know, try other springs myself and see what happens, just curious what others are running. i read an article where someone states to use the black springs (the stiffest) as the surge is most impressive with the black springs. The only thing with the black springs is the instructions state that the secondaries won't open fully, whereas with the purples they open fully at a certain RPM.
