I am no expert, but I believe that an NOS system done correctly will be activated automatically at a certain rpm. The nos jets are controlled by a special computer coupled with the ecu. I also believe that there is an arm button which you push to turn the system on/off. I hope I got this right.

Light goes green, leave at 4500rpm hard (on slicks), hit the juice about half a second after you launch and enjoy the ride.

If you find you bog before the juice kicks in, leave at a higher rpm.

It's that simple.

I take it you don't have the kit yet? Well I have a 50 shot and it seems to do the trick rather well. Almost too well. I need slicks. The problem I had was last time I went I was REALLY rushed. The night I went on just happened to be the test and tune night before the super chevy show. So I was rushed through. My nitrous lasts me awhile. I don't go spray crazy. I raced 3 times and I'm sure I have PLENTY left in the bottle. My biggest waste is purging. I just have a habit of purging it all the time. Good luck at the track though. I think you should be pulling low 14's high 13's rather regularly. IMHO

I will try to answer your question a little more in depth.
There are a few different NOS setups.

1. Dry manifold System
2. Wet Manifold System
3. Direct Port System
4. JWT Dry Manifold System

1. Dry Manifold System - Consists of 2 Nitrous solinoids and a NOS fuel pressure regulator. This systems is activated with a microswitch on the throttle body at WOT at any given RPM in any gear. Once the nitrous is activated , nitrous passes through the 1st NOS Solinoid , then passes though the NOS Pressure regulator. This bumps up your fuel pressure via your stock fuel pressure regulator. Passes through the second NOS solinoid and comes out through a nozzle placed as close to the throttle plate as possible.

2. Wet Manifold System - Consists of 1 Nitrous solinoid and a Fuel Solinoid. This systems is activated with a microswitch on the throttle body at WOT at any given RPM in any gear. Once the nitrous is activated , nitrous passes through the NOS Solinoid and routed to the "Fogger"nozzle, at this same time fuel passes through the Fuel Solinoid, which is tapped into your fuel line, and is routed into a "Fogger" nozzle. This "Fogger" Nozzle atomizes the fuel and nitrous before it enters the intake planum. This nozzle should be placed at least 12 inches away from the throttle plate to insure atomization.

3. Direct Port System - This system works exactly like a wet manifold system except rather than having one "Fogger" nozzle , you have one per cylinder plumbed into the intake manifold, hence the name "Direct Port" . This is a very aggressive , nitrous kit installed on most of the 11 second all Nitrous powered cars. This is usually controlled with a NOS Nitrous Master which can adjust % of nitrous entering the system per RPM.

4. JWT Dry Setup - This system is essentially a NOS Dry kit minus the NOS fuel regulator. JWT tunes the ecu and uses a NOS Module to switch the fuel and ignition maps when the nitrous is activated. There are 2 setups , a 50 shot which uses your stock injectors or a 100 shot setup which uses 370cc injectors from a Q45/300ZX TT. The 50 shot is activated at WOT @ 2000 rpms. The 100 shot is activated at WOT @ 4000 rpms. This system is used with one Nitrous solinoid from JWT. Ben B and myself both used 2 Nitrous Solinoids inline just as an added safety feature just in case one solinoid ever stuck open the second one would then close. You should launch with slicks out of the hole while the NOS is activated. All you have to do is activate the switch, Rev your motor at 5500-6500, drop the clutch and let the NOS do the rest of the work.

I hope this helps!

A purge kit is not necessary. I never had a purge kit. You can purge your system before you go to the track by driving the car in a high gear (4th or 5th) and activate the nitrous and hit the throttle. Once you feel the car pull, you know NOS is in the line.

or you can do a little burnout at the line too. I promise you will know when the nitrous hits.

Purging is basically adding an additional NOS solinoid inline BEFORE the primary NOS solinoids to "Purge" the line. Basically it clears the line to insure you have NOS, not air pockets, in the line.

Don't do your entire burnout on the bottle. Simply activate the nos while you are doing your burnout and just mash the thottle once, just to make sure NOS is in the line. That is it.
