Nitrous Express 66242-00 Dry Dual Stage Billet Crossbar Plate System Flange - 100-1000HP 4150

The Nitrous Express 66242-00 represents the next generation in crossbar nitrous plate technology for carbureted engines with 4150 flange manifolds. This dry dual-stage billet system delivers adjustable power from 100 to 1000 horsepower, making it suitable for street performance builds to serious race applications.

Advanced Billet Crossbar Design:

• CNC-machined billet aluminum construction eliminates traditional round spray bars for superior atomization and cylinder-to-cylinder distribution
• Rigid crossbar design prevents sagging, rotation, or airflow disruption common with conventional spray bar systems
• Dry configuration delivers nitrous only—fuel enrichment handled by carburetor jetting adjustments
• Dual-stage capability allows progressive power delivery for better traction control

Complete System Components:

• Custom solenoid mounting bracket for clean, secure installation
• Billet aluminum Y-fittings for professional appearance and durability
• Braided stainless steel lines from solenoids to plate for reliable, leak-free operation
• Nickel-plated fittings throughout for corrosion resistance
• Wide open throttle (WOT) activation switch ensures nitrous delivery only at full throttle
• Master arming switch provides safety control over system operation
• 40-amp relay and relay harness for proper electrical load management
• Comprehensive jetting selection for tuning across entire power range

This system is designed for 4150 flange applications and does not include a nitrous bottle. The dry configuration makes it ideal for carbureted racing applications where precise fuel control is maintained through carburetor tuning. Professional installation and proper tuning are essential for safe, reliable operation.
