Boost Cooler Stage 2 MAP (TSI/FSI)

The Stage 2 water/methanol injection system (for gasoline-powered engines) includes all the basic parts needed to start making big HP! Proper setup ensures superior power output, increased safety margin, reduced stress, and much-improved driveability. The engine load-referencing controller is truly the "special sauce" of a modern water/methanol injection system.

Expect 50degF+ drops in intake temperature and octane boost to over 110. (Non-intercooled engines will typically enjoy even greater reductions in air temperatures.) Includes: user-switchable MAP-based controller that varies the quantity injected vs. air flow for the smoothest power curve possible. Also equipped with 300 psi high volume pump, 3qt reservoir, two spray nozzles, Bosch relay, all electrical parts, fittings, tubing etc. to install a complete kit.

Nozzles MUST be sized properly to match total fuel flow, boost levels, and intercooling setup. Please contact USRT for help with this critical aspect of kit configuration. Other companies randomly provide nozzles that they have in stock with the lazy and false assumption that "one size fits all" applications. They abandon the user to to determine final setup on their own via trial and error. Dyno time is expensive and so are engine internals. Consult with our tech support to get it right from the very beginning.

Special Note: The controller in this kit only sees up to 20psi. Those running significantly more should add this high-boost controller upgrade. It sees up to 100psi for full protection at elevated manifold pressures.
