AQUAMIST 806-065C_3x1mm Water / Methanol injection kit HFS4-V3.1 for DI engines (red LED) 3x1mm jets

### Product Description __** Please note the HFS4 supports all DI engines under the "universal" option__ Update: we are offering a 3000cc/min pump option for 1000hp+ engines. It is not recommended for engines below 950hp. When this option is selected, we will include the 1600cc FAV and large flow sensor tube. In keeping with the excellent integration with the Di engines, the latest HFS4-v3.1 is packed with even more capabilities. An additional AUX input (0-5V) allows the system to alter flow based on air, exhaust temperature or air fuel ratio. If one of signals exceeds a pre-set level, failsafe will be triggered to protect your engine. The standard turbine flow sensor based failsafe remains. A “Fast Acting Valve” (FAV) controls the delivery rate based on a PWM signal from the HF4 controller. The FAV enables superior linearity and atomization across the entire injec- tion range. A constant line pressure (160 psi) is provided by an Aquatec pump working in the “by-pass” mode. This method is very similar to the conventional fuel injection sys- tems, allowing wide dynamic range and lighten responses to engine load. The combination of quality components, superior method of delivery and a precision Di signal decoding algorithm, the HFS4-v3 remains to be the most advanced and capable water/methanol injection system in the world to date.
