what did you calculate the Min/Max CSA of the X-cellerator to be? I know it's smaller than a Victor but IIRC it's bigger than a torker or Torker 2. Also has less taper than an M1 or the old Strip Dominator.
What is your opinion on runner length and how it effects flow? Longer strokes tend to like shorter runners when the cross sections are relatively small for the displacement, at some point the total runeer length itself (plenum to Valve) becomes a flow restriction. That's in part why I think (theorize) that a ported Victor could be a HP advantage over a SV on a longer 4+" stroke motor is the CSA and min/max CSa's were identical. additional Runner length tends to be beneficial below peak torque, but beyond that point becomes a HP restriction.(as RPM increases the motor would like the runner to be shorter and shorter = CLOSER to the carb)
It there a formula for runner taper (Plenum CSA relative to Runner outlet CSA) that works best for mopar Wedges? runner length (and more appropriately -Total Runner Volume) also comes into play here as well in terms of inertia tuning but that's too much to go into here I think.
