USRT Boost Trigga

  • Sale
  • Regular price $55.00

Need a simple and dependable way to activate your direct port or pre-compressor water methanol injection system? Or, perhaps you'd like to turn on a second fuel pump only under high load?

Look no further. Our adjustable boost switches can be set to activate between 10 and 60psi range. Adjustments are made via a small 1/8" Allen screw recessed in the top of the switch. Switch comes with normally open contacts making it perfect for a variety of functions.

Example: A sophisticated water/methanol setup would use a nozzle after the intercooler for air temperature control, direct port for octane boost, and also single nozzle mounted in the turbo inlet spraying directly at the compressor nut.

The post-intercooler nozzle would be set to spray at the point that intake air temperature reduction is needed. -typically at low boost. Once into heavy boost, octane is needed to protect the engine. So, the Boost Trigga is set to activate the direct port solenoid. Lastly, the pre-turbo nozzle's solenoid is activated as the turbo reaches the end of its efficiency zone. This will be found at/just after the torque peak (i.e. typically once the manifold pressure begins to drop at higher rpms). With this control arrangement, fluid consumption is minimized, tuning is easier, and a turbocharger flows air more like a larger one while still spooling quickly.
