Nitrous Express 60045-15 4150 Gemini Twin Stage 6 Alcohol Nitrous Plate System (50-300HP) with 15lb Bottle

The Nitrous Express 60045-15 is a complete 4150 Gemini Twin Stage 6 alcohol nitrous plate system delivering 50 to 300 horsepower in six selectable power levels. Engineered for carbureted applications running a standard Holley 4150 flange, this system is tuned specifically for alcohol fuel and ships complete with a 15 lb. nitrous bottle ready to run.

At the core of the Gemini Twin design is a spraybarless, direct-port spray pattern that delivers precise cylinder-to-cylinder nitrous and fuel distribution. This architecture eliminates the common problems associated with single-plane intake manifolds — particularly on small and big block Ford engines — while improving atomization and overall power consistency compared to traditional spray bar designs. With no spray bars to sag, split, obstruct airflow, or sustain damage, the Gemini plate represents a significant advancement in nitrous plate technology.

Key Features:

• Fits standard Holley 4150 flange carburetors — alcohol version
• Six power levels: 50, 100, 150, 200, 250, and 300 HP — all jetting included
• Spraybarless direct-port spray pattern for superior nitrous-fuel distribution and atomization
• Solves distribution issues common to single-plane manifolds, especially small and big block Fords
• Includes NX Lightning series solenoids with improved flow path for denser nitrous delivery
• Includes heavy-duty 40-amp relay for reliable high-current switching
• Includes stainless steel bottle brackets for secure mounting
• Includes extra-long D4 supply line (Race Hose) for flexible bottle placement
• Comes complete with 15 lb. nitrous bottle with billet aluminum Lightning bottle valve
• Limited lifetime warranty on Lightning solenoids

The Nitrous Express 60045-15 is the ideal solution for racers running alcohol-fueled carbureted setups who demand precise, consistent power gains across a wide range of shot sizes without the maintenance headaches of conventional spray bar systems.
