it might not be 50, but I personally think that it would be a better alternative to spending 1000+ on jag heads, or 3500+ on a supercharger
strapping a blower to a 10+:1 compression motor is not the greatest idea. Sure it'll work great with low boost, but you're really putting limitations on the tune (fuel/timing maps would have to be "extra safe") and the amount of total psi you can run, safely. Plus you have to overcome the power required to turn the supercharger...
those eatons are ok for stock applications (look at the 03 cobra) but when you really want to get serious, they fall well short of being efficient
