Race EFI Universal (Wet) Blackout Nitrous System
- Add 100-250 HP to Nearly Any EFI Racing Engine
- Fits Many Applications; View Product Page For Details
◄ Race EFI Universal Wet Nitrous System
For serious race applications, the ZEX™ Race EFI Nitrous System is the best choice. Featuring Fuel Shear™ Technology, enrichment fuel is injected directly into the center of the nitrous plume, yielding total and even fuel atomization. Tunable from 100-250 horsepower, the race kit features other important ZEX™ features such as Active Fuel Control™ to adjust fuel enrichment with fluctuations in bottle pressure and the patented ZEX™ electronic TPS switch for nitrous activation at wide open throttle.
Complete wet nitrous system; Includes everything for a safe, proper install
Adjustable from 100-250 HP w/ supplied tuning jets; Perfect for mild to wild performance
Multiple fuel tap fittings included to assure easy fitment to many applications
Detailed instructions provide for an easy, single afternoon installation
- Designed for serious street/strip & race applications
Why ZEX is SAFER, SMARTER, FASTER NITROUS
◄ Active Fuel Control™
Active Fuel Control™ is a revolutionary nitrous tuning and safety feature. In your engine, a vacuum is created as nitrous gas is sprayed across the open end of the nozzle’s fuel transfer tube. As bottle pressure rises or lowers due to bottle temperature changes, the speed of the nitrous discharge varies to the same degree. This causes the level of vacuum draw in the fuel transfer tube to vary as well. This variable vacuum draw causes the ZEX™ nozzle to actually “pull” more or less enrichment fuel into the engine. This means your engine never runs dangerously lean or overly rich. The nitrous tune-up stays dead-on for maximum engine safety and power at all times.
◄ 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.
◄ Fuel Shear™ Technology
ZEX™ Fuel Shear™ Technology injects enrichment fuel using a fuel transfer tube. This tube allows the ZEX™ nozzle to directly inject fuel into the highest velocity area of the nitrous plume. This high-speed nitrous shears the fuel away from the tube, atomizing it to levels other nozzle designs never achieve. This high level of atomization ensures perfect fuel distribution from cylinder to cylinder, ensuring one cylinder is never dangerously rich or lean, like competitor’s nozzles. This finely atomized mixture delivered by the ZEX™ nozzle also burns more powerfully and maximizes the horsepower you get from your nitrous system.
