Which guages are critical to have up front? One is mounted on the bottle already it is the the pressure guage. Also, how do i monitor how much shot of NOS i am spraying? Do you know by the pressure guage?? Any help appreciated.

 

I'm new at the nitrous thing. The gauges I have are the EGT, fuel pressure and nitrous pressure. The jet you place in the line determines how much you spray, unless you have some type of controller. The pressure gauge lets you tell what the bottle pressure is. It should be about 900-1100 psi from what I am told. Your purge can let some of the pressure out and the NX bottle heater will keep the pressure where it should be.
