GETTING TO KNOW THE AQUAMIST HFS-5
Over the last few years, demand for great engine power output is increasing. Cubic inches option is
no longer the norm. Squeezing out 200-300hp per litre is within the reach of the ordinary folks on the
street. The tuning industry has grown to embrace new tuning technique as well as readily affordable
components to produce powerful and reliable engines.
We, at Aquamist has also coming to terms with the inevitable, meeting the demands of the market
and offering new systems capable of supporting engine power output up to 1000+ BHP.
The HFS-5 reads the duty cycle of a fuel injector and delivers water proportional to fuel flow. Water
quantity is metered by a High speed inline valve and flow is monitored by a turbine flow sensor.
For clogged jet and severed hose. A number of options are available for the user to limit engine
power in the absence of water flow.
We believe the HFS-5 meets all the requirement of a high-end water injection system for achieving
fast engine transient and responses with absolute precision. Tracking the fuel delivery is the most
reliable method to deliver your fluid flow under the whole engine operating cycle. Anything short of
this means having to tailor your fuel map to compensate the irregular fluid quantity ingested by the
engine.
