Snow Performance Stage 2.5 Hellcat/Demon Water Injection System w/Billet Supercharger Lid

If you're looking to get the most out of your supercharged Dodge Challenger, Charger, or Jeep Grand Cherokee, especially if you're pushing higher boost levels, a water-methanol injection system is a smart addition. This Stage 2.5 system from Snow Performance is designed to cool your incoming air charge, which is crucial for boosted engines. Cooler air is denser air, meaning more oxygen can get into your cylinders, and that translates directly into more power and torque. It also increases the effective octane of your fuel, allowing for more aggressive ignition timing without risking detonation.

This kit includes a billet supercharger lid, which is a key component for ensuring proper nozzle placement and distribution of the water-methanol mixture directly into the supercharger's airflow. The system uses a high-output pump and a 3-quart tank, along with filtered nozzles and push-lock lines for a clean and reliable installation. A unique feature is the electronic controller that allows you to progressively manage the water-methanol output based on boost or vacuum levels, giving you precise control over when and how much mixture is injected. This advanced control means you get the benefits when you need them most, without over-injecting during cruising or low-load situations.

Beyond just cooling, this system can significantly reduce or even eliminate the need for timing retard when running nitrous oxide, further enhancing performance and safety. The kit comes with everything you need for installation, including the pump, tank, lines, controller, and the custom billet supercharger lid. It's designed to fit Dominator or 4500 series intake flanges, common on high-performance applications. Please note that this system is not CARB approved and cannot be shipped to California.
