What Nitrous safety features are available for Vipers?

[1BADSNK]

I'm using a BTR NOS/propane/gas kit and was wondering if there are any NOS safety features available to be used on the Viper. I have never ran juice on a car without a fuel pressure safety switch and an electronic box to pull timing out when activated.

My brand new Mallory pump for the gas injection took a crap on the dyno. I would like to prevent the juice from ever working if I lost fuel pressure again. Any Nitrous users out there using a fuel pressure safety switch or timing retard box?

A couple UK guys have brought BTR kits this year (one was a propane), they both had installed numerous safety devices which didnt come with the kit, which caters for everything except a blocked nozzle. Thats all I know, no technincal info.

I presently don't have any fuel presure safety switches. I am not sure but I have heard of people having problems with them on the viper.

As for other safety devices, I just put in a Nitrous RPM Window Switch/ Small shift light / Digital tach combination unit. Really is cool and works good. I can now program the nitrous to come on at what ever RPM I want to start spraying (of course once the main switch is on and the full throttle switch is on). I can also program it to stop spraying at the high end RPM, to avoid spraying should you ever bump the rev limiter.
Now it is nice I can arm the system and go full throttle and don't have to think about what RPM I am at the Shift light takes care of it.

I have a ton of safety stuff built into my system. It has a fuel pressure cutoff, O2 sensor that shuts it down if it leans out, a window switch that turns it on or off at whatever rpm I want, and a wide open throttle switch that also delays the spray for a tenth of a second after shifts in case I miss a gear. It should be fool proof, but I'm sure I'll find my way around that!

I have a WOT switch, fuel pressure switch, and Viper-modded MSD window switch. Plus the regular blow down tube, gauge, and I have a remote bottle opener and bottle warmer blanket.

I had bought a NOS-brand progressive controller box. But I didn't like the idea of a system that required a backup solenoid in line because the constantly strobing/pulsing main solenoid was actually expected to fail under use.

So I didn't install that unit, and everything works fine.
I just short-shift in first.

I have a vec2 and a saftey on the propane but the max #'s that I got so far I haven't even had to retard anything. The propane is a great way to go. The fuel saftey is comming asap.

Thanks for the responses guys. I'll check on getting the NOS rpm switch and a fuel pressure safety switch.
