I would like to know how to check my retard for each stage. i use a safety fuel pressure switch on the nos.. with a WOT switch. Im assumeing i need to jump out these 2 switches turn off fuel and nos. then activate each stage while having motor running and a timing light at the balancer.
Also i would like to know how to flow my fuel system for the NOS.
My goal is to run a small shot (75hp) on the first stage-turn off- then turn on 100hp second stage.
Sorry for being so long winded
Thanks in Advance

This is how I check mine, takes 3 people could be done with 2 though.
Person one has the timing light and watches the timing (usually me)
person 2 is holding the WOT switch down and running the throttle up some 2200-2500 rpms,
person 3 is hitting the nitrous push button in the car, or whatever activates the timer for a short period of time.
I unhook the nitrous line off just to be safe, rev the motor up to burn the extra fuel the nitrous is shooting in. This is also a good time to check your fuel pressure when doing this. Works great for me. Could tape the WOT switch to stay on if you wanted to use 2 people instead.
