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 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

Any IHRA or NHRA-sanctioned track will require blow-off caps in all classes when you run with nitrous oxide. These are safety devices that fit on the bottle. If your nitrous system creates too much pressure, a NOS blow-off cap will allow it to bleed off through the vent tube, which exits outside the vehicle. The caps are available in different styles for specific valve applications.

NOS two-stage wide open throttle/rpm-activated window switches are a compact, user-friendly way to eliminate the need for replacing rpm pills every time you want to change the activation rpm of your nitrous kit. They take window switches to the next level, too, eliminating the need for two rpm-activated window switches to control your two stages of nitrous! NOS two-stage wide open throttle/rpm-activated window switches feature two fully programmable independent rpm window switches. They can operate from 0 to 20,000 rpm for anything from a low-rpm engine to a high-revving sport bike, and they are perfect for carbureted or EFI vehicles. Their capability to read a rising or falling throttle position sensor provides accurate activation--every time. A programmable output activates a shift light for on-time, gear-pounding shifts, and the recall feature shows max rpm and TPS voltage for easy setup. NOS two-stage wide open throttle/rpm-activated window switches have a bright, easy-to-read display and bright LEDs that light up when stages are active for easy activation verification. These versatile switches can be used for nitrous or to activate other accessories.
