The efficiency range is not tested until the higher rpm range (where the S65 shines) because amount of air required... Do you agree with this?
While it does make sense its not 100% accurate. It would depend on many variables such as the type of supercharger used, pulley size ect. One supercharger can be more efficient then the other from 2000 to 7000 and still out perform the blower with the higher rpm efficiency. Maybe not on a dyno but in a real world situation where it matters.
Check out this dyno thread to check your theory. You will notice the differences in cars with the same or more rated Hp.
