Sometimes the application of too much power can be detrimental to a good launch. This is especially so when the vehicle chassis or prevailing track conditions contribute to a loss of traction. These are times when you need the help of a NOS® Dual Shot Cheater system to maximize performance from the starting line, all the way through the lights. It's like having two systems in one. The first stage is activated by a throttle switch on the carburetor and includes jets to add anywhere from 100-150 extra horsepower. Then, when the tires are fully hooked up, the driver can activate the second stage with a push of a button, or add a delay timer 15838NOS for the ultimate in consistency. The second stage immediately takes over and provides an extra 150 to 250 horsepower. Changing conditions can easily be accommodated simply by changing the nitrous jets, which takes just seconds to accomplish. The Dual Shot Cheater system incorporates two Super Powershot solenoids for the first stage and two Cheater solenoids for the second stage. The system includes a variety of power jets that can be used to reduce nitrous power output to as low as 50 horsepower. Other components included with the systems are a 10 lb. nitrous bottle, 1/2 injector plate, aircraft quality steel braided hose, and all necessary electrical and mounting hardware for a complete installation. This system is intended for use on V8 engines with a minimum displacement of 350 CID. For best results, a single plane intake manifold should be used.
