Throttle Position WOT Switch w/Bracket - 4150

The Throttle Position WOT Switch w/Bracket - 4150 from Nitrous Express is a precision electronic component engineered for high-performance nitrous oxide systems. WOT (Wide Open Throttle) switches are essential for any serious nitrous application, detecting full throttle conditions and triggering nitrous injection at peak engine demand. This component is purpose-built for dedicated drag racing, bracket racing, and street performance builds where controlled nitrous activation is critical to engine safety and consistent performance. Whether you're tuning a carbureted or EFI engine, this switch delivers the reliable throttle signal your nitrous system needs.

Mounted via an integrated bracket directly to your throttle linkage or pedal assembly, the WOT switch monitors throttle position and sends a signal to your nitrous controller only when the throttle reaches full travel. This prevents accidental nitrous activation during part-throttle driving, protecting your engine from lean conditions and detonation. The compact 4150 design weighs just 0.06 lbs, making it ideal for tight engine bays without adding significant mass. The bracket system allows precise adjustment and secure installation, ensuring repeatable throttle position detection across multiple passes and ambient conditions—critical for consistent ET's in competitive racing.

This WOT switch is ideal for racers and performance enthusiasts running Nitrous Express kits or any quality stand-alone nitrous controller that requires a WOT input signal. Installation requires mounting the bracket to your existing throttle mechanism—a straightforward job for anyone with basic mechanical skills and a socket set. Proper WOT switch tuning is non-negotiable for safety; once installed, validate that the switch activates only at genuine wide-open throttle by using a test light or multimeter before your first pass. Compatible with both carburetor and electronic fuel injection systems, this component is an indispensable addition to any nitrous-equipped platform.
