Show original supplier description
The Nitrous Express GENX-2 accessory package is designed to streamline the setup of your EFI nitrous system by providing all necessary components in one convenient kit. It includes an NHRA legal safety blow off fitting, a blow down tube, and a fuel pressure safety switch. The package features an automatic, pressure-controlled bottle heater that maintains optimal bottle pressure for consistent performance during launches and at top end speeds. A Nitrous Express nitrous pressure gauge with a color-coded bezel is included to quickly verify if the bottle pressure is within the ideal zone. The kit comes complete with relays, switches, wiring, and all necessary hardware for an easy installation. This accessory package is designed for use with a 4AN feedline. The included adjustable pressure switch can be set between 900 PSI and 1200 PSI, with a 50 PSI working window for consistent bottle pressure. The bottle heating element specifications are 240 Watts @ 12V, 312 Watts @ 13.8V, and 425 Watts @ 16V. The pressure switch features a 1/8 NPT port and is pre-set at 1050 PSI. The Gen-X package includes specific part numbers: #15940 Bottle Heater, #15508 Bottle Gauge, #11720 Fuel pressure Safety Switch, #11709 NHRA Blow Down Tube Fitting, #11708 Blow Down Tube, and #15600 Nitrous Purge kit. Due to the adjustability of the pressure switch, this kit is compatible with all nitrous kits on the market.
