 For V8 engines with Holley Dominator carburetors, two stage (100 to 150 HP first stage and 150 to 250 HP second stage), Dual Shot Cheater nitrous oxide system Often times, the application of too much nitrous at the starting line can ruin a good launch. The NOS Dual Shot Cheater nitrous system is designed with this in mind. It injects nitrous oxide into your engine in two stages. The first stage is an adjustable 100 to 150 HP, turned on by a throttle-activated microswitch to allow the car to leave the line under full traction. Then, with the tires fully hooked up, the second stage is activated with a push button switch that provides another adjustable power increase of 150 to 250 HP. The system includes two Super Powershot solenoids for the first stage, two Cheater solenoids for the second stage, an unfilled 10 lb. nitrous bottle, a 1/2 in. injector plate, filters, fittings, a variety of power jets, switches, aircraft-quality steel braided hose, and all other necessary hardware for a complete installation.
