nitrous is a chemical supercharger. the pressure remains realitivly the same but the oxygen content is increased chemicaly.
to simplyfy:
at sea level the airpressure is roughly 15psia. with a 10:1 compression engine the pressure inside the cylinder is at 150psi (15 * 10 = 150) (roughly obviously valve overlap and other variables will change this this is a simplifycation.)
add 15 psi of boost to the 15psia of the air pressure for a total of 30 psia
(this is still a 10:1 comp engine) so 30 * 10 = 300 psi! thats ALOT of pressure.
Dont forget that when we compress a gas it heats up too!
now nitrous is injected at sea level (15 psia) When the liquid nitrous flashes off into a gas as soon as it hits ambiant air pressure (this has a cooling effect on the surrounding air.)
nitrous is N20 two nitrous atoms and one oxygen atom. (33% oxygen)
At sea level on a 59* day with low humidity there is 21% oxygen in the air.
so, there is the payoff more oxygen to add fuel to.
Depending on how much you have to spend, you will probably want a ProCharger, or turbo system. Also, if you haven't done any suspension, chassis, or tire work... how do you plan on hooking up? I would say do some suspension, and put a sticky tire on.

The suspension will have subframe connectors, adjustable panhard bar, and a new torque arm. The rear wheels are going to be 17x11s, and I may use stickies for the race. Is there anything else for the suspension that will help me hook up better?

First of all......Am I the only one who thinks that he should have no problem taking him with his combo??? He should make AT LEAST 420hp at the wheels with the 383....depending on what kit he's spraying with....and what shot he uses(150-200) should put him between 560 on the low end with a 150....and as high as 610-620 on the high side if he squeezes with the 200 shot.
That being said, my first opinion is that your converter is a bit small....honestly I would have gone with AT LEAST a 3500 stall on that motor/gear combo. Cam is respectible as long as you go with one of the later/larger ones you mentioned. If you can get the power to the ground.....I think you should wipe the pavement with this guy depending on what else he has done besides the blower.
Just my .02 take it for what its worth, and let us know what happens.

p.s........Definitely get yourself a set of LCAs(lower control arms) with relocation brackets, and some sticky tires

I will keep you guys posted on what happens. I am using a 3000 stall because I want to keep this car very streetable. It will be my daily driver, so I don't want to go too high. Would a 3500 stall be very streetable? I know my stall is larger than his.
