Banderlog (Water Injection Valve)
What is it? This little box is an electric valve that cuts off cooling water to your headers if the engine RPM falls below its set point. This set point can be either 1,500 RPM or 2,000 RPM.

• Positive water shutoff to headers at preset RPM. No more fooling with block pressures.
• Two presets, 1,500 RPM & 2,000 RPM. Selectable by installing a jumper.
• Included metering valve to adjust the amount of water that flows through the headers.
• Simplified cooling system.
• Trailer running. Because it uses RPM to control the header water, it works equally well on a garden hose.
• Racing cutoff. If you would like to race with dry headers, there is an optional cutoff to run dry for up to 13 seconds, when the throttle is held wide open.

Banderlog (HEI Signal Converter)
If you plan on running a Banderlog water valve with a GM HEI distributor, you must use one of these.

Why? The Tach. Signal provided by GM HEI ignitions is not compatible with Banderlog water injection valve. The Banderlog HEI Signal Converter converts this HEI Tach signal into a compatible signal for the water injection valve.
