I forgot to ask for pros and cons about the supercharger if any. Thanks!

 

pros: more power! more torque! bolt-on! factory-warranty!
cons: uses more fuel, constant increased roughness on the engine (whereas nitros(NOS) is only for a short-period, and with a turbo... spools/kicks-in at high rpms...whereas SC is ALWAYS boosting)

Rambo is pretty much dead-on as far as the pros & cons go, but...

I'm not so sure about the "factory warranty" bit. Unless you can buy a supercharger direct from Nissan / Infiniti, installed by a dealer with written proof that it will not affect your engine's warranty, you better consider you've tossed the warranty out the window as soon as you bolt the sucker on. At 10:1 + compression, the G35's powerplant is in no way designed, or able to handle a supercharger with any significant boost. Most supercharged engines utilize 7:1 or lower pistons, because your average supercharger is going to roughly double the starting compression ratio. Newer units designed for higher compression engines may work with much lower boost levels, but the added performance suffers as a result. Instead of a true "supercharger", you've got more like an "instant-on turbo" instead.

"Bolt-on" is a bit over-simplistic. It's a little more involved than changing an air filter... and definitely not something for your average shade-tree mechanic to considering doing himself. But the same holds true for a turbo.

yeah, true, he was talking about his Seqouia though, the TRD 4.7L V8 supercharger that adds 120HP and 140 torque
