Upgrade your Progressive Nitrous Control System with one of these NOS safety application kits. What these kits do is give you an extra nitrous solenoid and hardware to plumb into your existing nitrous system. They reduce plunger wear in the regular nitrous solenoid, thereby extending its life and reliability. Also, the safety kits close line pressure and prevent nitrous from building up in the intake manifold when the ignition is turned off. This eliminates engine destruction and unwanted fireworks under the hood when the ignition is turned back on.

Features:

  • For Time Based Nitrous Control
  • For Wet Manifold EFI Kits
  • For Carburetor Kits
  • Not Required for Dry Manifold Kits
The NOS Cheater system uses large nitrous and fuel solenoids that can be adjusted for power levels up to 250 horsepower, in a matter of seconds. Cheater systems are easy to install and utilize a 1/2" thick injector plate which fits between the carburetor and intake manifold to provide ample hood clearance. These systems are available in both single-stage and dual-stage models. Dual-stage models are best suited to those applications where full power cannot be applied at once, due to traction limitations. However, even greater control can be realized by using an NOS Progressive Nitrous Controller, shown elsewhere in this catalog. Cheater systems include a 10 lb nitrous bottle, four (4) stages of jets, aircraft-quality steel braided lines and all necessary electrical and mounting hardware for a complete installation. Each single carburetor Cheater system includes Jet Pack #13725 that allows jetting to four (4) different horsepower levels: 150, 180, 210 and 250. Each multiple carburetor Cheater system includes Jet Pack #13735 that allows jetting to four (4) different horsepower levels: 150, 175, 200 and 250.

Features:

  • Large Nitrous and Fuel Solenoids
  • Adjustable In a Matter Of Seconds
  • Easy To Install
  • Thin 1/2" Injector Plate
  • Gives Ample Hood Clearance
  • Includes Necessary Electrical Hardware
The NOS Big Shot systems use a special "fogging" plate design that vastly improves nitrous flow, fuel atomization and mixture distribution. This Big Shot plate utilizes a unique spray bar that is equipped with tiny orifices. These are precisely located to efficiently dispense a powerful nitrous/gasoline mixture for unbelievable horsepower. Power output is adjustable from 190-300 horsepower simply by changing fuel and nitrous jets. Single stage Big Shot systems incorporate a NOS Pro Shot nitrous solenoid with -6 AN nitrous supply line. Systems include a variety of power jets, nitrous bottle, 1/2" fogging plate, filters, fuel and nitrous fittings, switches and all electrical and other hardware necessary for installation. Big Shot fogging plates are available separately.

Features:

  • Unique Fogging Plate Design
  • Vastly Improves Nitrous Flow
  • Improves Fuel Atomization
  • Improves Mixture Distribution
  • Advanced EDM Technology
  • Highly Efficient Nitrous System

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.

Features:

  • Maximum Performance From Starting Line
  • Like Having Two Systems In One
  • Both Stages Adjustable
  • Includes Power Jet Variety
  • 1/2" Injector Plate
  • Aircraft Quality Braided Hose
  • Includes Necessary Electrical Hardware
