All the heavy modders end up against this ceiling for a reason. The supercharger gets so far out of it's efficiency range that added boost gets offset to a great degree by that inefficiency. I stacked my Code3 with the 178 and my 1/8 mile was faster but the 1/4 was the same. That's our problem. Hence, nitrous, cams/head work, turbo, larger custom supercharger, acceptance or moving on are the choices. I'll keep chipping away for the foreseeable future. I kinda see a possibly of cams and head work in my future. Time will tell if I have the fortitude to make the leap.
