you gained the compression ive herd (compression gains abut 4% of hp per 1 point of compression like from 10:1 to 11:1 ) some say you gain from 10-20 hp depending on the engine itself but you lost boost you get about 10-20 hp per pound of boost depending on size and cfm of the supercharger so depending on the supercharger itself it may have just equaled each other out
