Our engine has an awesome powerband where it actually matters (5500 to 7500 rpm), and I'm sure theirs does as well.

I'm not sure why people would be so caught up about low-end torque on a Z car. They've always been high-strung and gutless down low, with the exception of the 300ZX TT and maybe the 350Z.

which is why it needs tq there and why low end tq cars will get the jump on us.

Again, only if you roll race from 3500 rpm.

As far as acceleration is concerned, torque doesn't mean anything - all that matters is effective horsepower. If you're already within your powerband, you're set.

BTW, a centrifugal supercharger doesn't add much if any low-end torque. It'll probably start giving you extra power starting at 4000 rpm or so, with gains climbing from that point. I think that's accurate based upon the Stillen and GTM supercharger dyno sheets I've seen. Centrifugal superchargers are all about making more top end torque/horsepower. Imagine your torque curve being absolutely flat from 3500 or 4000 to redline - that's what this type of supercharger will get you.
