You'll see that the objective of a Super Charger is generally the same as a turbo. However, one does this much more efficently.

And be fore you degrade what works for everybody else - Check the credibility of you're source. If your friend had bad luck with a turbo setup, and theres lots of people here telling you there good then i wouldn't be so quick to take his advice on getting a JRSC. Im almost positive that the Fuel Delivery on his setup is very similar to that offered by Jackson Racing.
