safety equipments?

Honestly, it's tough to watch all the gauges in the quarter mile, and my car has not been tuned on the nitrous yet. But hopefully when I pill up on the dyno I'll be able to pay real close attention to everything.
I also tried wiring my fuel and N2O noids in series so if the fuel noid failed the N2O would not spray but the noids draw too much current in series so it would have required getting pretty fancy with multiple relays and I didn't want to over engineer it. KISS as they say
