The operation is very simple: The Boost Cooler system starts injecting when the boost switch reaches the user-adjustable point and it injects a fixed amount of fluid through the nozzle until the switch opens again.

This kit progressively injects more or less water or water/alcohol, according to manifold boost pressure. The system is applicable for turbo diesels making up to 1.7bar of boost pressure. It has two dials to set the start and full points to tailor the delivery to your engines needs. Progressively injecting according to boost pressure allows for the most power over the widest range of rpms.
