Nitrous Express 66447-00 Dry Quad Stage Billet Crossbar Plate System Flange - 100-2000HP 4500

The Nitrous Express 66447-00 represents the pinnacle of dry quad-stage nitrous injection technology, engineered for high-performance carbureted applications requiring 4500 flange compatibility. This professional-grade system delivers adjustable power levels from 100 to 2000 horsepower through four independently controlled stages, making it ideal for serious racers and performance enthusiasts.

Advanced Billet Crossbar Technology:

• CNC-machined billet aluminum construction eliminates traditional round spray bars for superior nitrous atomization and cylinder-to-cylinder distribution
• No spray bars to sag, rotate, or disrupt critical airflow through the intake system
• Precision-engineered flow paths ensure consistent nitrous delivery across all four stages
• 4500 flange design fits Dominator-style carburetors and intake manifolds

Complete System Includes:

• Custom billet aluminum solenoid mounting bracket for secure installation
• High-flow braided stainless steel lines from solenoids to nitrous plate
• Billet aluminum Y-fittings for optimized flow distribution
• Nickel-plated AN fittings for corrosion resistance and professional appearance
• Wide-open throttle (WOT) activation switch for precise nitrous engagement
• Master arming switch for enhanced safety control
• 40-amp relay and complete relay harness for reliable electrical operation
• Comprehensive jetting for 100-2000HP power range across four stages

Important Note: This is the 66447-00 model which does not include a nitrous bottle. Nitrous bottle, lines, and bottle valve must be purchased separately. This configuration is perfect for racers who already own bottles or prefer to source their own bottle setup.

Designed and manufactured by Nitrous Express, the industry leader in high-performance nitrous systems since 1996. Professional installation and proper tuning are strongly recommended for optimal performance and engine safety.
