Yo Ken,Superchargers create more pressure in cylinders and therefore create more engine power. Nitrous creates more pressure in cylinders and therefore creates more engine power. Superchargers are expensive, drain power from the engine up to a certain RPM, and lower your MPG. Nitrous you turn on when you want, it's cheap, and no MPG problems. For a daily driven 07GT and an infrequent racer, doesn't it make sense to do nitrous or am I missing something? Thanks, Jim Lagergren Johnson City TN.
