2. What cams would you be able to run on a supercharged motor? As in a mildly aggressive to a very aggressive profile.

3. Is there a difference between turbo boost (psi) vs supercharger boost(psi)? (example 10psi on a turbo vs 10psi pulley)
All I have to say is, do your research. Know what power (HP, Trq) numbers you are looking at, then search for setup and prices. If a SC gives you the numbers you want then just go ahead and go with that, if a turbo makes enough for you to have fun then do that. Also look at install time and cost of install if you don't DIY.

All I know is that a turbo might have more CFM and LBS compared to a belt driven SC. I think the belt creates to much of a drag on a engine as a turbo doesn't but then they both have there drawbacks as well.
