And I feel like this should be noted.
Forced induction is a sure way to kill a stock long block. Your stock iron heads are only good for high 9.x/1 at best. With the stock 9.4 c/r if you ONE pound of boost you're at 10.2~.
This is partially why i never thought about a supercharger before without forged internals. On the other hand, boosting doesn't change the compression ratio, just increases pressure itself in the cylinder. Compression ratio compares the volume of a cylinder at bottom stroke versus top dead center. The cylinder volume or head chambers are not increasing in size. Only thing increasing is cylinder pressure.
