Nitrous Express 60545-12 4150 Gemini Twin Pro-Power Alcohol Nitrous System with 12 lb Composite Bottle

The Nitrous Express 60545-12 is a complete, single-stage wet nitrous oxide injection kit built around the Gemini Twin plate — one of the most technically advanced carbureted nitrous plate designs available. Engineered for alcohol fuel applications, this Pro-Power system delivers repeatable, consistent power gains ranging from 100 to 500 horsepower using the included interchangeable jet set.

The Gemini Twin plate uses a unique direct-port spray pattern that provides even nitrous and fuel distribution across all cylinders, directly addressing the distribution challenges common on single-plane intake manifolds. With no traditional spray bars, there is nothing to sag, restrict airflow, split, or suffer mechanical damage — resulting in superior atomization and outstanding consistency run after run.

Kit Includes:

• Gemini Twin nitrous plate — fits standard 4150 square-bore flange carburetors
• 12 lb lightweight composite nitrous bottle with high-flow billet aluminum Lightning bottle valve
• Limited lifetime warranty Lightning Series solenoids with CNC aluminum bodies and carbon fiber cans
• Heavy-duty 40-amp relay and relay harness
• Stainless steel bottle brackets
• Extended 4AN Race Hose supply line for flexible routing
• Jet pack with jetting for 100, 200, 300, 400, and 500 HP power levels
• Wide-open throttle switch and master arming switch

System Specifications:

• Nitrous system style: Wet (simultaneous nitrous and fuel delivery)
• Plate delivery style: Square-bore (4150 flange)
• Activation: Wide-open throttle microswitch
• Maximum advertised power increase: 500 HP
• Fuel type: Alcohol only
• Bottle material: Composite (lightweight)

The Lightning Series solenoids feature an improved flow path that eliminates sharp turns and expansion zones, keeping nitrous in a dense liquid state for maximum power efficiency. The integrated purge port on each solenoid also reduces plumbing complexity for a cleaner installation. This kit is designed specifically for alcohol fuel applications and is not intended for gasoline use.
