BTW, boost is boost. Doesn't matter SC or turbo.
That is incorrect. SC'ers loose 3% per 1,000ft just like an NA engine as they are a closed circuit (belt driven).
Turbo's have sensors to reach target boost.
Well that depends on the SC setup. Although some can be limited by belt pulley size, newer ones can also be limited via bypass valve and other electronic tricks. So it's possible for SC cars to be able to keep the same boost level similar to a turbo. Only thing is that they will lose in the low-end and top-end (if they originally tapered down without electronic nannies) due to being mechanically linked via the crank. So it may take more RPM to achieve the same boost level and it may taper off the boost sooner as well due to lower air densities.
