SYSTEM INFORMATION:
This system is designed for use with Holley HP and Dominator EFI systems. It is not a stand-alone system. The components are designed for 100% water and up to a 50/50 percent mixture of water and methanol. Windshield washer fluid is commonly used. Do NOT use more than 50% methanol in the mixture, or damage to components may result.
NOTE: If you use other hardware in the installation of this system, it must be compatible with the fluid you use. Brass, aluminum, steel, natural rubber, and silicone are not suitable for use with a water/methanol mix and should not be used.
NOTE: The solenoids must be driven by an ECU injector driver output. If an extra injector driver channel is not available, a PWM output can be used to trigger Holley PN 554-115. This is a two channel injector driver device that can control two water meth solenoids using two high (+) or low (-) side PWM outputs.
PARTS REQUIRED:
This kit is an installation kit only. A pump and solenoid(s) are required as well. Note that you must use Holley solenoids for proper operation in conjunction with HP and Dominator EFI systems. The system is set up to allow up to two solenoids to be controlled. These parts are offered by Holley in the following PNs:
557-100 – Pump. This is not an “off the shelf agricultural pump”. It is designed for water/methanol injection.
557-103 – Solenoid/Nozzle Assembly (includes bung) 600cc/min – 400 HP engines
557-105 - Solenoid/Nozzle Assembly (includes bung) 900cc/min – 600 HP engines
557-106 - Solenoid/Nozzle Assembly (includes bung) 1000cc/min – 800 HP engines
557-107 – Replacement Filter
2 solenoids – If you are running two solenoids, you need a “T” fitting to go to them. McMaster-Carr PN 5182K434 or 8239K223 can be
utilized.
System Setup - Injection Mode: Duty Cycle (%) Mode – Injects based on the program’s duty cycle entered. Fuel Flow (%) Mode – This is the advised method of injection. Injects a precise volume of water/methanol mix, which is a percentage of the actual engine fuel flow at that point.
System Setup - Number of Outputs: Definition: Select from 1 or 2 solenoid outputs. Note that an injector driver output is required for this function. If one is not available, a PWM output can be used to drive Holley PN 554-113.
System Setup - Output Mode: Definition: Selects method that dual nozzles will be sequenced.
· Sequential – One nozzle will be ramped in as the duty cycle of the other approaches 100%.
· Parallel – Both will be fired at the same time.
System Setup - Manual Enable: Definition: Enabling this will create a switched input that allows the water/meth system to be completely disabled if desired. If the switched input is turned off, the water/meth system will never activate and the pump will not run. If the switched input is turned on, the water/meth system will activate as programmed.
System Setup - Turn Pump Off: Definition: Time for pump to turn off after activation. If the “turn pump off after non-use” time is set to 0 seconds, the water/meth pump will run all the time when the engine is running. If the “turn pump off after non-use” time is set to a value above 0 seconds, the pump will turn on when water/meth injection is commanded and turn off after the programmed time. It will then turn back on once water/meth injection is commanded again.
System Setup - Low Reservoir Warning: Definition: Enabling will create an input to the ECU from a low reservoir warning.
Low System Safety: Definition: Used if low Reservoir warning is enabled.
Low System Safety - Timing Reduction: Definition: Amount that timing will be retarded if low reservoir warning is enabled.
Low System Safety - Max Boost: Definition: If boost control is employed, amount that boost will be limited to.
