SafeInjection™

For years, many have wanted to use water/methanol injection but have not taken advantage of the power increases do to safety concerns. Designed as an ad-on to the Boost Cooler® water/methanol injection system, Safe Injection™ provides for a safe tune in those instances where no injection is present and an aggressive tune is utilized.“ This system reduces boost or timing anytime injection quantity goes below a set point (e.g. if reservoir level goes too low) making the tune instantly conservative for the ultimate in safe water/methanol injection.

Features

  • The Safe-Injection System by Snow Performance is designed to ensure reliability for highly modified performance vehicles using the Boost Cooler Water/Methanol Injection Systems. The unit can detect the following faults and will output a 12 volt trigger signal in the event a fault occurs.
     
  • No Water/Methanol fluid
  • Blocked Nozzle or hose
  • Pump Failure
 
SI-05 Controller

 
 
 

SI Solenoid

   

Operation / Installing

The SI-05 can be installed in the engine bay of the vehicle. Do not mount the SI-05 directly on the engine block or damage to the product may result.

Insert the high pressure line from the output of the pump into the quick connect fitting labeled PUMP on the front of the SafeInjection unit. Pull on the hose after inserting to insure a tight connection. Insert a second high pressure hose into the quick connect fitting labeled NOZZLE on the front panel. The other end of this hose is to be connected to the nozzle holder included in the Boost Cooler kit.
 

Adjustable Delay
The SafeInjection unit has a user adjustable delay that can be used to control the speed at which the trigger signal is activated. The adjustment dial is located on the back of the SI-10 next to the electrical connector.
 


Add-On Solenoid
For turbo application equipped with a waste gate, the trigger signal can be used to activate a solenoid to divert full boost pressure to the waste gate, there by bypassing a boost control device. This will limit the boost pressure generated by the turbo to the level set by the waste gate. The lower boost level will prevent a lean A/F (air/fuel) condition that could result from the lack of water/methanol leading to combustion detonation. The diagram below shows how the setup can be accomplished.
