Boost Cooler Stage2 NA

The Stage2 NA water/methanol injection system (for normally aspirated gasoline-powered engines) provides all the basic parts needed to start making big HP! High-compression and advanced ignition timing on pump fuel is no problem because octane surges well past 100.

Includes: engine load-referencing (MAP/MAF) controller that varies the quantity injected vs. air flow for the smoothest power curve possible. Also equipped with 220 psi high volume pump, 3qt reservoir, two spray nozzles, Bosch relay, all electrical parts, fittings, tubing etc. to install a complete kit.

Alternately utilize this kit to safely and easily tame the savage beast that is Nitrous Oxide.

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.
