Nitrous Express 60540-00 4150 Gemini Twin Pro-Power Nitrous Plate System 100-500HP Less Bottle

The Nitrous Express 60540-00 4150 Gemini Twin Pro-Power Plate System is a single-stage nitrous plate system engineered for high-performance gasoline applications on standard 4150 flange carburetors. Delivering adjustable power from 100 to 500 horsepower in five jetting stages, this system gives racers and performance enthusiasts precise, tunable control over their nitrous output.

At the heart of the Gemini Twin design is a unique direct-port spray pattern that delivers even nitrous and fuel distribution across all cylinders. This architecture directly addresses the uneven distribution problems commonly encountered with single-plane intake manifolds, especially on small block and big block Ford engines. With no traditional spray bars in the flow path, there is nothing to sag, split, restrict airflow, or sustain damage — resulting in superior atomization and more consistent power delivery.

The system ships as a complete kit, less bottle, and includes NX Lightning solenoids featuring an improved internal flow path that eliminates sharp turns and keeps nitrous in dense liquid form for maximum efficiency. The Lightning solenoids carry a limited lifetime warranty and are built with CNC-machined aluminum bodies and carbon fiber cans for an optimal strength-to-weight ratio.

Kit Includes:

• Gemini Twin Pro-Power 4150 nitrous plate
• Jetting for 100, 200, 300, 400, and 500HP power levels
• NX Lightning solenoids (limited lifetime warranty)
• Heavy-duty 40-amp relay
• Stainless steel bottle brackets
• Extra-long 4AN D6 Race Hose supply line
• Fits standard 4150 flange carburetors (Holley 4-bbl style)

Sold as a system less nitrous bottle — pair with your choice of NX nitrous bottle to complete the setup. Ideal for strip and competition use where a high-output, configurable single-stage plate solution is required.
