Things you should know before purchasing.  
Nitrous is the cheapest way to get substantial power, followed by Turbo. Compare Nitrous kits from $390, Turbo kits from $2699 and Supercharger kits $5500.

Nitrous kits simply bolt right on with the minimum of effort and fits any vehicle, any engine carb or fuel injected. The big benefit of nitrous is you are using it ONLY when you need it, otherwise engine is running complete stock. And to change the power, simply change the jets. Couple of minutes.
AFR is controlled by a Power Commander or Bazzaz fuel controller. Small jetting can be controlled by your airbox sensor.
Nitrous is NOT Nitro Methane. Nitro methane is a fuel used by top class Drag bikes/cars and is in no way similar or linked to nitrous oxide. In fact they couldn't be more different, as nitro methane is a flammable fuel, while nitrous oxide is a non-flammable oxidiser.

Summary: Nitrous can be run very simply just by pressing the button to spray nitrous into your airbox.
Turbos use the exhaust to power the twin turbine which rotates the induction part that pulls ambient air into the throttle bodies (two turbines that are directly linked to one another).  Its a very clean system that does not use any engine power to force air into the engine.  The benefit of ProBoost Turbo kits is they use the stock rad and oil cooler, providing excellent performance, but making road and highway riding better for the motorcycle.
Superchargers leach power from the engine, so less power overall. In racing, you don't need low end power since your never low in the rpm band.  
Running a turbo on a  low boost is easy, but larger boost would in our opinion require an extended swingarm. Racing kit provides more control over boost delivery.
