Dry Nitrous System

ZEX™ Dry Nitrous Systems incorporate the patented Active Fuel Control™ Technology, which monitors the nitrous bottle pressure and adjusts fuel enrichment to achieve the perfect mixture. This ensures your engine will never run too rich or too lean when you engage the nitrous system. ZEX™ nitrous activates at wide open throttle using an electronic switch that monitors your engine’s TPS sensor. The design ensures that your nitrous is engaged at the perfect wide open throttle position every time.The design of the ZEX™ Dry Nitrous System makes it a simple and easy, 2 hour installation. ZEX™ Dry Nitrous Kits only work properly with fuel injected return-style fuel systems.

Active Fuel Control™

One of the most innovative safety and power features of our dry nitrous system is the "Active Fuel Control". The ZEX™ Dry Nitrous System's fuel control circuit references the actual bottle pressure and adjusts the fuel enrichment accordingly. If it is a cool day and the nitrous bottle pressure is around the 700 psi range, the nitrous system will add less enrichment fuel than if it is a warm day and the nitrous bottle is at 950 psi. This unique feature ensures that you always have the optimum ratio of nitrous and fuel. Never too rich, never too lean. It also ensures maximum power and safety at all bottle pressures.

TPS Sensor Activation

Our throttle position sensor switch is truly innovative. For years, nitrous systems have been activated by use of crude push buttons and throttle arm activated micro switches. These devices were very difficult to install and were constantly failing because of the extreme temperatures found in vehicle engine bays. ZEX™ integrated advanced microprocessor control circuits into our nitrous systems so that they "learn" the voltage curve of an engines throttle position sensor. This enables our nitrous systems to activate at wide-open throttle, precisely and reliably, every time.
