Enthusiasts around the nation are switching to water/methanol injection. The kits work by injecting a fine mist of water/methanol into the intake tract to ward off detonation, increase air density, add timing and power. In fact, it’s not uncommon to see good gains in horsepower and torque with this equipment. So Snow Performance, a water/meth specialist, has just released its stage 3 kit for BMWs equipped for the 3.0-liter twin-turbo N54 engine. The kit features a three-dimensional controller that offers more versatility and smoother power than previous products. Special mapping for the N54 provides accurate injection. The new system also has an LCD screen that displays boost, fuel injector duty cycle and injection pump output.
