Snow Performance Pumpless Water/Methanol SystemNX Pumpless water methanol systems inject the water methanol mixture into the intake charge pipe at high pressure(user adjustable 100 400PSI) providing excellent atomization even in high boost applications. These systems include a pressurized reservoir that eliminates the need for an electric pump. The adjustable pressure regulator allows the user to fine tune the amount of water methanol injected into the engine without swapping different size
