Nitrous Oxide Systems
NOS is one of the oldest and most prestigious names in nitrous technology. Using proven knowledge attained through experience since the '70s, NOS kits boast superior quality and fitment with proven performance. Some of the biggest names in professional drag racing credit NOS for their success, which can be attributed to its constant refinement and innovation in the field. Among the latest and greatest, NOS developed one of the first out-of-the-box direct-port kits using a revolutionary technology that requires no drilling or tapping of the intake manifold. The patented NOSzle system slips underneath the injectors for superior atomization and is available for any Gen III motor. The brand-spanking-new spray-bar-less plate system is currently available for all Gen IIIs and will accommodate throttle bodies up to 80mm. It is designed to reduce the air turbulence normally associated with spray bars. Meanwhile, the LT1 dry kit with integrated Holley 58mm throttle body is still a crowd favorite due to its superior packaging.

Nitrous Pro Flow
Using the same break-through engineering talent that created the LSX manifold, Wilson Manifolds brings a number of innovations to the table in its line of Nitrous Pro Flow nitrous kits and accessories. Nitrous Pro Flow specializes in direct-port kits, which use the patented V-Force Nozzle designed to introduce the nitrous-fuel mixture into the intake tract more gradually and naturally. An oval spray pattern is created that can better fill the port rather than a disruptive fan or wedge that is more likely to cause excessive fuel wash. The 90-degree Nozzle is CNC-machined from 303 stainless steel with stainless steel entry fittings and a 1/16-inch NPT thread. Flow matching is not required because of the Nozzle's precise machining, however, the entire kit is flow-tested if you opt for the installed version in either your stock or Wilson manifold. The patented distribution block also comes with the kit, along with the solenoids and hard lines, however to complete the install you will need the System Completion Kit ($409.75-424.75). Included in the Completion Kit is NPF's innovative bottle design. The patented valve design uses a radiused inlet and large-diameter pick-up tube to outflow the competition by 360 lb/hr according to in-house testing. Along with a 10- or 15-pound bottle, the kit consists of quick-release bottle brackets, a 16-foot feed line, a nitrous bottle pressure gauge, and a line adapter with a built-in filter.

Nitrous Works
While Nitrous Works is usually associated with its parent company Barry Grant, EFI racers will soon be giggly over Nitrous Works' Billet Atomizer Plates and Power Wing Nozzle kits. The full line of wet nitrous systems for TBI, TPI, LT1, and LS1 motors are designed to be compatible with OEM components and do not require an additional fuel pressure regulator or upgrade. Gen I and II motors use a freeze-free plate that bolts to the throttle body, while the Gen III kit places a Power Wing Nozzle in virtually any location along the intake tract. The same feat can be achieved with the Universal Power Wing Nozzle Kit available in single, dual and triple stages-with one nozzle for each stage. High rollers can purchase the Universal Pro Nozzle Kit for single- and dual-stage direct port systems capable of 1,200 hp.
