Clamp pressure is clamp pressure. You get it low base + centrifugal, i get it high base - whatever i choose to temporarily hold back. You have reduced clamp pressure on launch, so do I. You have more clamp come in later to keep the clutch from slipping down track, so do I. I pointed out the difference in clamp after the shift, something you don't necessarily want from your setup but can't do anything about. My setup can launch higher than yours without knocking the tires loose.
You keep saying i wear out clutch discs, but typical slip time here on launch is around 1 sec. How long does your clutch slip on launch?
