Often times, the application of too much nitrous at the starting line can ruin a good launch. The NOS Dual Shot Cheater nitrous systems are designed with this in mind. They inject 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 systems include 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.
