depends 100% on the engine and what tuning is done to it. It isnt always so much that you can run more boost as it is the more dence air with the same boost along with the added safety.
Take the Tiburon V6 for example.
Stock they have about 150whp
With a supercharger at 9psi that figure more than doubles. All they do is tune it, boost it, and add WI. with out the WI they wouldnt be able to have as aggresive tuning, this along with the WI itselft wouldnt let it make as much power, and it wouldnt be as safe.
