The NOS Pro Race Fogger system represents the ultimate in state-of-the-art direct port nitrous injection technology. Simply state, it produces the largest horsepower gains of any single stage nitrous system available today and is designed for all-out competition-only import four cylinder and rotary engines. Several top-running "Pro" Imports have recorded 7-second clockings with this system. The primary benefit of port injection is that fuel/nitrous charge for each particular cylinder. And, because of the cool, dense "fog" like charge of atomized fuel and nitrous, it will produce optimum power. Some of the key components in this system are a Super Hi-Flo bottle valve, Pro Race solenoids (the highest flowing available) Y-shaped distribution blocks, stainless steel lines and your choice of Soft Plume 90 degrees or Annular Discharge stainless steel nozzles. They are adjustable to produce power gains from 80 to well over 225 hp

Note: Due to the high power levels and cylinder pressures produced by the Pro Race Fogger System, you must use high strength forged pistons, rods, and crankshaft. Use of cylinder head and main studs will help insure reliability. A high quality racing ignition system with timing control must be used with these systems. Use of racing gas (100 Octane plus) is recommended
