The vortech makes more peak horsepower, but it doesn't do so until near redline. The JRSC from what I've seen has a much flatter torque curve, and much more usable power. Neither of them is really unique, but then again not much is nowadays. If I was going to do something, it would be turbo. It is not belt driven like a blower, and therefore reduces the parasitic losses from the engine. Remember, the superchargers are driven from the crankshaft. Turbo will allow for further growth and power output as you decide to go faster and build your motor.
