PWM Controlled CWA400 Pump and Trunk Mounted Ice Tank
For the best performance -16an (1 inch) line is highly suggested!
The CWA400 is a beast of a coolant pump but it comes at the cost of high amp draw on your electrical system. Over time this will reduce the life of the pump itself and your charging system. The fact is the coolant pump doesn't need to run full speed all the time so we got together with Kaizen Speed to utilize their CAN cased relay. The Kaizen relay receives data directly from your CTS-V CAN messaging system to control the CWA400 pump speed. A detailed explanation of pump control will be listed below but the Kaizen relay will look at things like intake air temp, vehicle wheel speed, throttle position and engine RPM to dictate the duty cycle of the coolant pump. Only pushing the pump hard when necessary.
Operating parameters:
- Engine running = 35% duty cycle
- Accel Pedal > 50% = 100% duty cycle
- Cruise Control button latched = 100% duty cycle
- IAT > 135 degrees = 100% duty cycle
What's included:
- DMS 7.5 Gallon Tank with the dimensions of 20" Length, 12.25" Width, 8.5" Height
- Pierburg CWA400 PWM Coolant Pump
- Kaizen Relay with Plug and Play wiring harness
- Drain Fittings
- 6 Inch Plastic Tank Lid
- Feed/Return Pushlock fittings for pump/tank and 50 feet of high quality hose (Either 12an or 16an depending on selected options)
