NOS Solid State Relays
NOS solid-state relays address the need for reliable, rugged, and affordable control of various electrical equipment on your race car. Originally designed to control the high-current switching loads of nitrous solenoids, these relays can also be used to control other high-current devices—such as electric water pumps, trans-brakes, and line locks. NOS relays feature an ultra-low activation/release time of less than 16 microseconds to ensure no delays in reaction times. The solid-state relays can also be Pulse Width Modulated (PWM) with no minimum-duty cycle at frequencies up to 1000hz. NOS solid state relays feature: * 5-20 V DC operation * Rugged solid-state circuitry * Easy 3-wire connection * Included terminated pigtail * Included extra contacts for build-your-own wiring * Ultra-fast activation, under 16 microseconds * Pulse Width Modulation (PWM) compatible * PWM 0-100 percent * Up to 1000hz frequency * Vibration-resistant * Maximum continuous current = 40 amps * Maximum switching current = 20 amps

NOS Cheater Nitrous Oxide Systems
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
