NOS Cheater nitrous oxide systems are designed with the serious racer in mind. They feature larger nitrous and fuel solenoids than the Powershot systems and can be adjusted in a matter of seconds to add an additional 150 to 250 hp, simply by changing fuel and nitrous jets. They use a thin, 1/2 in. injector plate that fits between your carburetor and intake. Highly accurate spray bars within the plate simultaneously inject both nitrous and fuel into the manifold, creating a smooth rush of extra power on demand. Kits are also available without the bottle or injector plate. They are not recommended for intake manifolds with a separate inlet for each carburetor throttle bore, except for 3 x 2-barrel setups. Racing fuel is recommended. Most kits come complete with: * Unfilled nitrous bottle * Cheater nitrous and fuel solenoids * Injector plate * Filters * Fittings * Four stages of jets * Switches * Aircraft-quality stainless steel braided hose * All other necessary hardware for a complete installation

Holley Dominator billet fuel pumps feature a patent-pending twin-pump design. It allows you to use one pump for cruising and both pumps when you activate the nitrous switch or start building boost. By staging the second pump, you eliminate the unnecessary recirculation and heating of extra fuel, which can lead to poor performance and hot fuel issues. They can also be wired for full-time duty to get the maximum performance and are proven with an 18 V compatibility at pressures of up to 80 psi. At only 5.1 lbs., they weigh half a pound less than other 1,000 hp pumps, and yet they have twice the features. Features include: * Billet aluminum construction with anodized finish * -10 AN O-ring inlet/outlet for high flow and superior sealing * Excellent for use with carburetor or EFI applications * Compact for easy installation on frame rails or other tight spaces * Proven durability beyond 3,000 hours in gasoline or diesel fuels * Fully sealed, can be submersed if necessary
