Patented nozzle technology provides better atomization for maximum horsepower! • Tunable from 100-250 additional engine horsepower • Fuel Shear™ technology injects enrichment fuel directly into the nitrous plume for better atomization • Active Fuel Control™ adjusts fuel enrichment in accordance with bottle pressure • Features a patented electronic TPS switch for perfect system activation at wide open throttle The just released ZEX™ Race EFI Nitrous System incorporates several nitrous technology breakthroughs; making it the perfect choice for serious race applications. One such patentworthy advancement is ZEX™’s Fuel Shear™ technology, which injects the enrichment fuel directly into the center of the nitrous plume yielding total and even fuel atomization. As with every ZEX™ nitrous system, the new Race EFI System includes the tuning and safety feature that has revolutionized the nitrous industry - Active Fuel Control™. Fuel enrichment is automatically adjusted in accordance with bottle pressure, so tune-ups stay dead-on despite bottle pressure fluctuation. In addition, the Race EFI Nitrous System also utilizes a patented electronic TPS switch for perfect system activation at wide-open throttle. Tunable from 100 to 250 horsepower, the new ZEX™ Race EFI Nitrous System is compatible with any fuel injected engine.
