Most nozzle designs are all alike. Other manufacturers may change a hole location here or atip angle there, but in reality, there really hasn?t been a breakthrough in nozzle technology inover 20 years? until now. The most important function of a nozzle is to properly mix andatomize the correct amounts of nitrous and fuel. Some designs spray a solid stream of fuelat the nitrous stream and hope that it will atomize properly. Other designs are forced to runexcessively rich, so when nitrous bottle pressure and flow increase, their systems won?t rundangerously lean. ZEX has developed two new nozzle technologies that not only give ourdesign the ability to atomize the fuel to levels never achieved before, but also to adjust fueldelivery on its own. The result is a nozzle that atomizes fuel and nitrous better than any previousdesign and provides the optimized tune-up at all bottle pressures. These groundbreakingtechnologies give you a significant power advantage over conventional nozzles. 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 velocityarea 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 highlevel 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.
