The Nitrous Express Gemini Pro-Power Alcohol kit for 4150 flange carburetors includes jetting for 100–500 HP and a composite nitrous bottle for reduced weight. The single-stage Gemini plate uses a direct-port pattern for superior nitrous-fuel distribution and atomization, and ships with Lightning solenoids, a 40A relay, stainless bottle brackets and an extra 4AN long supply line.
