Im looking at one of these kits from Snow performance.
Water Methanol Injection Gas Stg 3 MPG-MAX Boost Cooler
The MPG MAX® Stage 3 Boost Cooler® is unmatched for increases in Fuel Economy AND Power in water-methanol injection systems. Key to this is accuracy and adjustability designed into the system. This Boost Cooler® can be used on ANY EFI engine (naturally aspirated or forced induction) and any forced induction application (EFI or Carbed).
In the lighter load states, it can read and inject according to either EFI Fuel Injector Pulse-width or Boost level, or any combination of BOTH! This allows it to be extremely accurate when injecting smaller amounts to prevent quench.
Additionally, the MPG MAX® Has the software and hardware capable to inject the correct amounts under the higher load states for serious increases in power.
Very easy to set up and dial in - the software creates a 3 dimensional delivery map from just a few easy to set start and full points you punch in.
The LCD Screen displays boost pressure, Injector Pulse width %, as well as water-methanol injection percent. Quick, easy, positive adjustments are made with 2 push buttons. Low profile design allows for easy-to-view and discrete mounting.
Kit includes:
• 150+ PSI High Volume Pump
• 3 Quart Reservoir
• LCD Screen, Pushbutton Digital Variable 3D Mapping Controller
