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.

Tech Resources

To supply the proper amount of fuel to the carburetor and Cheater System, a fuel pump must be used that is designed to operate between 5 and 10 psi, with a flow rate of 0.1 gallons per hour per horsepower at 6 psi. For example, an engine that produces 450 horsepower when the Cheater System is activated will require a fuel pump that flows at least 45 gallons per hour at 6 psi. This Nitrous system includes the 12500NOS Nitrous Plate that is Legal for Use in DXP Street Racing Class.
