Vince, you are, like, _spectacularly_ dim.

Tar is a program.  It reads datafiles, and writes new files based on
what it reads.  It is not magic.  If it reads a tarfile that tells
it to create a setuid root file, it will try to do so.

Note that about half a dozen people have said _very_plainly_ that to 
create or make a setuid root file one _must_already_be_root_.

Or am I just wasting my ulcer on you?
