Nitrous Oxide - nozzle placement

I am wanting to spray 50 shot on my car to cool the intake charge. i see most of you doing this use 2 nozzles one on each side of the procharger box. can i just use one nozzle or is it a must to run two.

Anyone?

1 nozzle should be just fine, maybe the people running two are using a TNT kit that comes with 2 nozzles.
