so your telling me i should buy a bottle heater and a gauge right? the gauge is just going to tell me what the pressure is at and i wont be able to do anything unless i have a heater?

Its also better to have a gauge in the cockpit vs on the tank so you can see it all the time without having to look in the trunk.

It's a must. What if the nitrous pressure is at 1200psi? You could be running lean.

hey jime i noticed about a month ago on your sig you were running a 13.6 now you ran a 13.1. what have you done to get the better times? nice times!!!

I helped a bit on a Zex install they are somewhat different than NOS and NX at least the electronics.

NOS has a good bottle heater. An Autometer #4374 gauge is good, too. You also should consider an EGT gauge. Summit Racing can sell you all these items.
The bottle warmer ensures your bottle pressure is optimal, for safer, more consistent runs. The pressure gauge helps you monitor the bottle pressure so you can keep it in the optimal range. Pressure too low? Turn on the heater. Pressure OK, or running high? Turn the heater off.
The heater is controlled by a thermostat, but you still want to ensure you don't leave your switch "on" when you leave your car. You also want to ensure you wire the heater to a circuit that is "hot" only when your ignition is turned on. All this provides a redundant safety system that keeps your car from peeling itself from the inside out, if you know what I mean...
The EGT gauge helps you monitor exhaust gas temps, to detect any abnormal increase, indicating a lean condition. If you see the EGT heading skyward, take your foot out of it at once!
Good luck.

If you park your car outside in a hot summer day, it will reach that high. An interior of a car can reach 90+ degrees easily. Bottle pressure have a direct correlation to heat. 75F will yield around 900psi. The hotter it is, the higher the pressure. There are plenty of times when my bottle pressure is at 1100psi. Anyways, it's less of a problem on Zex or dry kit since fuel pressure will rise as bottle pressure rise. On a wet kit, forget about it. The fuel system have no idea what your bottle pressure is. Better hope your setup runs on the richer side.

Lots of people run without either heater or gauge but if you have a heater yes you must have a gauge. The pressure will never go that high unless you heat it.

What I was really trying to say before is that if you are on a budget you can get away without a heater, gauge etc as long as you stay away from high shots. I know of a couple of guys who race regularly that have just a base kit ie no warmer, gauges, window switch etc etc and do very well at the races. That said if you really want to be consistent you need to know and have the pressure the same all the time.

Do you guys run a Nitrous line into the cockpit for a pressure guage, or have your found/forked over the $ for an electric pressure guage.

My whole nitrous line runs through the cockpit and likewise the pressure gauge. But I don't do what everyone else does, so expect a whole bunch of people who do different than me.

I ran a ss braided line from my engine bay before the nitrous solenoid to my a-pillar. That was a PITA.
