You'd be crazy to throw water into a gas tank and expect to get anywhere—but power and torque can be increased if you inject it into the incoming air charge with Nitrous Express water/methanol injection systems. Cooling the air charge allows for increased timing and the resulting performance benefits. These versatile units have a wide open throttle switch for naturally aspirated vehicles and an adjustable boost-activated switch for forced induction models. Nitrous Express systems inject a fixed amount of fluid when the WOT switch or boost is activated—and continues until the switch opens again. They reduce intake temperatures and the need for timing retard when used with nitrous. Stage II kits come complete with a high-output pump, 3 qt. reservoir, nozzle, boost activated progressive controller, switch, hardware, and detailed instructions. Water has always been used to cool motors down, but with Nitrous Express water/methanol injection systems … it'll be heating things up!
