Show original supplier description
The LAP3 Stage4 Water Methanol Injection Kit is an advanced system designed to optimize engine performance. It uses a PWM controller that leverages engine RPM, boost PSI, and throttle position to create a 3D adjustable water-methanol injection strategy. Furthermore, it decreases cylinder temperatures by up to 300 degrees, helps reduce the effects of heat soak in warmer climates, and enables the safe application of more boost and timing. The kit facilitates increased octane at user-programmable boost levels, contributing to a cleaner combustion chamber by reducing carbon buildup. Key components included are the LAP3 Injection Control Module (ICM) with harness, a Snow Performance Meth Tank, a 300 PSI rated pump, and a Snow Performance nozzle with holder, along with nylon tubing. The system is controlled via the PROSS METHAN App, allowing for detailed Injection Duty Cycle tuning. Please note that this item does not work with the LAP3 Pro-Tuner. A link to the Pro-Tuner V2 Meth Kit and the installation guide are provided.
